  15. <title>The Mozilla Blog: Firefox DNS privacy: Faster than ever, now on Android</title>
  16. <guid isPermaLink="false">https://blog.mozilla.org/?p=81686</guid>
  17. <link>https://blog.mozilla.org/en/firefox/dns-android/</link>
  18. <description>&lt;p&gt;All web browsing starts with a DNS query to find the IP address for the desired service or website. For much of the internet’s history, this query is sent in the clear. &lt;a href=&quot;https://en.wikipedia.org/wiki/DNS_over_HTTPS&quot;&gt;DNS-over-HTTPS (DoH)&lt;/a&gt; plugs this privacy leak by encrypting the DNS messages, so no one on the network, not your internet service provider or a free public WiFi provider, can eavesdrop on your browsing.&lt;br /&gt;&lt;br /&gt;In 2020, Firefox became the first browser to roll out &lt;a href=&quot;https://blog.mozilla.org/en/firefox/firefox-continues-push-to-bring-dns-over-https-by-default-for-us-users/&quot;&gt;&lt;strong&gt;DoH by default&lt;/strong&gt;&lt;/a&gt;, starting in the United States and in 2023, we announced the Firefox &lt;a href=&quot;https://blog.mozilla.org/en/mozilla/news/firefox-by-default-dns-over-https-rollout-in-canada/&quot;&gt;DoH-by-default rollout in Canada&lt;/a&gt;, powered by our trusted partner, the Canadian Internet Registration Authority (CIRA).&lt;/p&gt;
  19.  
  20.  
  21.  
  22. &lt;p&gt;This year, we’ve built on that foundation and delivered major performance improvements and mobile support, ensuring more Firefox users benefit from privacy without compromise.&lt;/p&gt;
  23.  
  24.  
  25.  
  26. &lt;h3&gt;&lt;strong&gt;Introducing DoH for Android&lt;/strong&gt;&lt;/h3&gt;
  27.  
  28.  
  29.  
  30. &lt;p&gt;After bringing encrypted DNS protection to millions of desktop users, we’re now extending the same to mobile. Firefox users who have been waiting for DoH on Android can now turn it on and browse with the same privacy protections as on their desktops.&lt;/p&gt;
  31.  
  32.  
  33.  
  34. &lt;p&gt;Starting with this week’s release of &lt;strong&gt;Firefox 143 for Android&lt;/strong&gt;, users can choose to enable DoH in Firefox on their mobile devices by selecting “&lt;a href=&quot;https://support.mozilla.org/en-US/kb/configure-dns-over-https-protection-levels-firefox-android#w_increased-protection&quot;&gt;Increased Protection”&lt;/a&gt; DoH configuration. Performance testing with &lt;a href=&quot;https://wiki.mozilla.org/Security/DOH-resolver-policy#Conforming_Resolvers&quot;&gt;Firefox DoH partners&lt;/a&gt; is currently underway. If DoH is as fast as we expect, we plan to enable it by default for Android users in certain regions, similar to desktop users. Until then, these configuration options provide you the choice to opt in early.&lt;/p&gt;
  35.  
  36.  
  37. &lt;div class=&quot;wp-block-image is-style-default&quot;&gt;
  38. &lt;figure class=&quot;aligncenter size-large wp-duotone-000000-8ed1fc-1&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-81687&quot; height=&quot;1024&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/09/image-683x1024.png&quot; width=&quot;683&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;&lt;em&gt;Enable DoH in Firefox on Android&lt;/em&gt;&amp;lt;/figcaption&amp;gt;&lt;/figure&gt;&lt;/div&gt;
  39.  
  40.  
  41. &lt;h3&gt;&lt;strong&gt;DoH performance breakthroughs in 2025&lt;/strong&gt;&lt;/h3&gt;
  42.  
  43.  
  44.  
  45. &lt;p&gt;DNS resolution speed is critical to the browsing experience — when web pages involve multiple DNS queries, the speed difference compounds and can cause page loads to be slow. Since we first rolled out DoH in Canada, we’ve worked closely with CIRA for reliability and performance measurements. Through our strong collaboration with them and their technology partner Akamai, Firefox DoH lookups are now &lt;strong&gt;61% faster&lt;/strong&gt; year-to-date for the 75th percentile.&lt;/p&gt;
  46.  
  47.  
  48.  
  49. &lt;p&gt;With these performance improvements, DoH resolution time is now within a millisecond or two of native DNS resolution. This is a big win because &lt;strong&gt;Firefox users in Canada now get the privacy of encrypted DNS with no performance penalty&lt;/strong&gt;.&lt;/p&gt;
  50.  
  51.  
  52.  
  53. &lt;p&gt;Although the investigation and analysis started with the desire to improve DoH in Firefox, the benefits didn’t end there. Our collaboration also improved CIRA DoH performance for many of its DNS users, including Canadian universities, as well as other DNS providers relying on CIRA’s or Akamai’s server implementations.&lt;/p&gt;
  54.  
  55.  
  56.  
  57. &lt;p&gt;This is a win not just for Firefox users, but for the many other users around the globe.&lt;/p&gt;
  58.  
  59.  
  60.  
  61. &lt;h3&gt;&lt;strong&gt;Robust privacy on your terms&lt;/strong&gt;&lt;/h3&gt;
  62.  
  63.  
  64.  
  65. &lt;p&gt;We have always approached DoH with an emphasis on transparency, user choice, and strong privacy safeguards. Firefox gives users meaningful control over how their DNS traffic is handled: Users can opt out, choose their own resolver, or adjust DoH protection levels, and Firefox makes it clear what DoH is doing and why it matters.&lt;/p&gt;
  66.  
  67.  
  68.  
  69. &lt;p&gt;Firefox enforces strict requirements for DNS resolvers before trusting them with your browsing. Not every DNS provider can become a DoH provider in Firefox — only those that meet and attest to Mozilla’s rigorous &lt;a href=&quot;https://wiki.mozilla.org/Security/DOH-resolver-policy&quot;&gt;Trusted Recursive Resolver (TRR) policy&lt;/a&gt; through a legally binding contract.&lt;/p&gt;
  70.  
  71.  
  72.  
  73. &lt;h3&gt;&lt;strong&gt;Prioritizing your privacy and speed&lt;/strong&gt;&lt;/h3&gt;
  74.  
  75.  
  76.  
  77. &lt;p&gt;Our work with DoH this year shows what’s possible when privacy and performance go hand-in-hand. We’ve proven that encrypted DNS can be fast, reliable, and available on desktop and Android. Just as importantly, we’ve shown that partnerships grounded in open standards and accountability can deliver benefits not only to Firefox users but to the wider internet.&lt;/p&gt;
  78.  
  79.  
  80.  
  81. &lt;p&gt;As we look forward, our commitment stays the same: Privacy should be the default, speed should never be a compromise, and the web should remain open and accessible to everyone. Choosing Firefox means choosing a browser that is built for you and for a better internet.&lt;/p&gt;

  96. <title>Firefox Developer Experience: Firefox WebDriver Newsletter 143</title>
  97. <guid isPermaLink="false">https://fxdx.dev/?p=510</guid>
  98. <link>https://fxdx.dev/firefox-webdriver-newsletter-143/</link>
  99. <description>&lt;p&gt;&lt;em&gt;WebDriver is a remote control interface that enables introspection and control of user agents.&lt;/em&gt; &lt;em&gt;As such it&lt;/em&gt; &lt;em&gt;can&lt;/em&gt; &lt;em&gt;help developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the&lt;/em&gt;&lt;a href=&quot;https://www.w3.org/&quot;&gt;&lt;em&gt; &lt;/em&gt;&lt;em&gt;W3C&lt;/em&gt;&lt;/a&gt;&lt;em&gt; and consists of two separate specifications:&lt;/em&gt;&lt;a href=&quot;https://w3c.github.io/webdriver/&quot;&gt;&lt;em&gt; &lt;/em&gt;&lt;em&gt;WebDriver classic&lt;/em&gt;&lt;/a&gt;&lt;em&gt; (HTTP) and the new&lt;/em&gt;&lt;a href=&quot;https://w3c.github.io/webdriver-bidi/&quot;&gt;&lt;em&gt; &lt;/em&gt;&lt;em&gt;WebDriver BiDi&lt;/em&gt;&lt;/a&gt;&lt;em&gt; &lt;/em&gt;&lt;em&gt;(Bi-Directional).&lt;/em&gt;&lt;/p&gt;
  100.  
  101.  
  102.  
  103. &lt;p&gt;&lt;em&gt;This newsletter gives an overview of the work we’ve done as part of the Firefox 143 release cycle&lt;/em&gt;.&lt;/p&gt;
  104.  
  105.  
  106.  
  107. &lt;h3&gt;Contributions&lt;/h3&gt;
  108.  
  109.  
  110.  
  111. &lt;p&gt;Firefox is an open source project, and we are always happy to receive external code contributions to our WebDriver implementation. We want to give special thanks to everyone who filed issues, bugs and submitted patches.&lt;/p&gt;
  112.  
  113.  
  114.  
  115. &lt;p&gt;In Firefox 143, two contributors managed to land fixes and improvements in our codebase:&lt;/p&gt;
  116.  
  117.  
  118.  
  119. &lt;ul&gt;
  120. &lt;li&gt;Liam (ldebeasi) implemented the logic to &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1754273&quot;&gt;emit events for existing contexts&lt;/a&gt; when subscribing to the &lt;code&gt;browsingContext.contextCreated&lt;/code&gt; event.&lt;/li&gt;
  121.  
  122.  
  123.  
  124. &lt;li&gt;Sabina (sabina.zaripova) &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972865&quot;&gt;added an internal helper&lt;/a&gt; to make it easier to check our session data.&lt;/li&gt;
  125. &lt;/ul&gt;
  126.  
  127.  
  128.  
  129. &lt;p&gt;WebDriver code is written in JavaScript, Python, and Rust so any web developer can contribute! Read&lt;a href=&quot;https://firefox-source-docs.mozilla.org/devtools/getting-started/README.html&quot;&gt; how to setup the work environment&lt;/a&gt; and check&lt;a href=&quot;https://codetribute.mozilla.org/projects/automation&quot;&gt; the list of mentored issues&lt;/a&gt; for Marionette, or the&lt;a href=&quot;https://codetribute.mozilla.org/languages/javascript?project%3DWebDriver%2520BiDi&quot;&gt; list of mentored JavaScript bugs for WebDriver BiDi&lt;/a&gt;. Join&lt;a href=&quot;https://chat.mozilla.org/#/room/#webdriver:mozilla.org&quot;&gt; our chatroom&lt;/a&gt; if you need any help to get started!&lt;br /&gt;&lt;/p&gt;
  130.  
  131.  
  132.  
  133. &lt;h3&gt;WebDriver BiDi&lt;/h3&gt;
  134.  
  135.  
  136.  
  137. &lt;h4&gt;Updated: &lt;code&gt;browsingContext.contextCreated&lt;/code&gt; for existing contexts&lt;/h4&gt;
  138.  
  139.  
  140.  
  141. &lt;p&gt;Updated the &lt;code&gt;browsingContext.contextCreated&lt;/code&gt; event to be &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1754273&quot;&gt;emitted for all open contexts&lt;/a&gt; when subscribing to the event.&lt;/p&gt;
  142.  
  143.  
  144.  
  145. &lt;h4&gt;New: several commands to record network data&lt;/h4&gt;
  146.  
  147.  
  148.  
  149. &lt;p&gt;We implemented several new commands for the network module to enable recording network data.&lt;/p&gt;
  150.  
  151.  
  152.  
  153. &lt;p&gt;&lt;strong&gt;&lt;code&gt;network.addDataCollector&lt;/code&gt;&lt;/strong&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971778&quot;&gt;adds a network data collector&lt;/a&gt; to &lt;code&gt;contexts&lt;/code&gt;, &lt;code&gt;userContexts&lt;/code&gt; or globally. The collector will record network data corresponding to the provided &lt;code&gt;dataTypes&lt;/code&gt;. At the moment, only the &lt;code&gt;&quot;response&quot;&lt;/code&gt; data type is supported. A &lt;code&gt;maxEncodedDataSize&lt;/code&gt; must also be provided, network data exceeding this size will not be recorded.&lt;/p&gt;
  154.  
  155.  
  156.  
  157. &lt;p&gt;&lt;strong&gt;&lt;code&gt;network.removeDataCollector&lt;/code&gt;&lt;/strong&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971781&quot;&gt;removes a previously added network data collector&lt;/a&gt;.&lt;/p&gt;
  158.  
  159.  
  160.  
  161. &lt;p&gt;&lt;strong&gt;&lt;code&gt;network.getData&lt;/code&gt;&lt;/strong&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971780&quot;&gt;retrieves the data collected&lt;/a&gt; for a provided &lt;code&gt;request&lt;/code&gt; id, &lt;code&gt;dataType&lt;/code&gt; and optionally &lt;code&gt;collector&lt;/code&gt; id. When providing a &lt;code&gt;collector&lt;/code&gt; id, clients may also pass the &lt;code&gt;disown&lt;/code&gt; flag to release the network data from the collector. Note that data is deleted when it is no longer owned by any collector.&lt;/p&gt;
  162.  
  163.  
  164.  
  165. &lt;p&gt;&lt;strong&gt;&lt;code&gt;network.disownData&lt;/code&gt;&lt;/strong&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971779&quot;&gt;releases the data&lt;/a&gt; for a given &lt;code&gt;request&lt;/code&gt; id and &lt;code&gt;dataType&lt;/code&gt; from the provided &lt;code&gt;collector&lt;/code&gt; id.&lt;/p&gt;
  166.  
  167.  
  168.  
  169. &lt;h4&gt;Bug fixes:&lt;/h4&gt;
  170.  
  171.  
  172.  
  173. &lt;ul&gt;
  174. &lt;li&gt;Fixed a bug where &lt;code&gt;emulation.setLocaleOverride&lt;/code&gt; &lt;a href=&quot;https://bugzil.la/1980137&quot;&gt;did not apply the override to newly created cross-origin iframes&lt;/a&gt;.&lt;/li&gt;
  175.  
  176.  
  177.  
  178. &lt;li&gt;Fixed a bug where several commands such as &lt;code&gt;session.subscribe&lt;/code&gt; would &lt;a href=&quot;https://bugzil.la/1949037&quot;&gt;fail if any tab was unloaded&lt;/a&gt;.&lt;/li&gt;
  179.  
  180.  
  181.  
  182. &lt;li&gt;Fixed the &lt;code&gt;browsingContext.navigationCommitted&lt;/code&gt; event so that the &lt;code&gt;url&lt;/code&gt; property &lt;a href=&quot;https://bugzil.la/1980137&quot;&gt;now includes basic auth credentials&lt;/a&gt;.&lt;/li&gt;

  188. <title>Mozilla Future Releases Blog: Raising the Minimum Android Version for Firefox</title>
  189. <guid isPermaLink="false">https://blog.mozilla.org/futurereleases/?p=2729</guid>
  190. <link>https://blog.mozilla.org/futurereleases/2025/09/15/raising-the-minimum-android-version-for-firefox/</link>
  191. <description>&lt;p&gt;Mozilla has always aimed to make Firefox available to as many people as possible, including those on older Android devices. For years, we’ve supported versions of Android going all the way back to 5 (Lollipop), which first launched in 2014. That broad support has helped extend the life of many devices. However, the Android ecosystem is constantly evolving and it has become increasingly difficult for us to find ways to maintain and develop apps on these long-unsupported platforms while also allowing Firefox to take advantage of more modern devices and Android operating systems.&lt;/p&gt;
  192. &lt;p&gt;Beginning with Firefox 144, &lt;strong&gt;the minimum supported Android version will increase to 8.0 (Oreo)&lt;/strong&gt;, which was released in 2017. At the same time, we will end support for 32-bit x86 Android devices. Usage of these older platforms has become increasingly rare, and continuing to support them has made it harder for us to deliver the best performance and reliability to the vast majority of our users.&lt;/p&gt;
  193. &lt;p&gt;If your device runs Android 7 or earlier, or if you rely on Firefox for a 32-bit x86 device, Firefox 143 will be the final version available to you. You will still be able to use that version, but it will no longer receive updates once Firefox 144 is released. Please note that 32-bit ARM devices will continue to be supported.&lt;/p&gt;
  194. &lt;p&gt;These changes apply not only to Firefox for Android but also to Firefox Focus &amp;amp; Klar, our privacy-first browsers. By narrowing our supported platforms, we can take better advantage of modern Android APIs, improve stability and security, and focus our engineering resources where they will have the greatest impact.&lt;/p&gt;
  195. &lt;p&gt;We know some users will be affected by this transition, and we don’t take that lightly. Our goal remains to balance broad accessibility with the ability to deliver the best possible Firefox experience on modern hardware and operating systems.&lt;/p&gt;
  196. &lt;p&gt;The post &lt;a href=&quot;https://blog.mozilla.org/futurereleases/2025/09/15/raising-the-minimum-android-version-for-firefox/&quot;&gt;Raising the Minimum Android Version for Firefox&lt;/a&gt; appeared first on &lt;a href=&quot;https://blog.mozilla.org/futurereleases&quot;&gt;Future Releases&lt;/a&gt;.&lt;/p&gt;</description>

  201. <title>Mozilla Thunderbird: Mobile Progress Report – July/August 2025</title>
  202. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3793</guid>
  203. <link>https://blog.thunderbird.net/2025/09/mobile-progress-report-july-august-2025/</link>
  204. <description>&lt;p&gt;Hello wonderful community, it has been a while since the &lt;a href=&quot;https://blog.thunderbird.net/2025/07/mobile-progress-report-june-2025/&quot;&gt;last Mobile update&lt;/a&gt;.&lt;/p&gt;
  205.  
  206.  
  207.  
  208. &lt;p&gt;A lot has happened in the past 2 months, so let’s jump right into a quick overview of current work in progress and primary efforts.&lt;/p&gt;
  209.  
  210.  
  211.  
  212. &lt;h4&gt;Account Drawer in progress&lt;/h4&gt;
  213.  
  214.  
  215.  
  216. &lt;p&gt;If you’re rocking the Beta version of Thunderbird for Android, you might have noticed that all your unified folders have disappeared! Don’t panic, that’s just temporary.&lt;/p&gt;
  217.  
  218.  
  219.  
  220. &lt;p&gt;We’re still churning through the technical debt and the database inconsistencies in order to create through virtual unified folders for all your accounts.&lt;/p&gt;
  221.  
  222.  
  223.  
  224. &lt;p&gt;The final goal is the same as the one we shared in a previous update, which you can see the final mock-ups here:&lt;/p&gt;
  225.  
  226.  
  227.  
  228. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/09/Mobile-Update-July_August.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3794&quot; height=&quot;647&quot; src=&quot;https://blog.thunderbird.net/files/2025/09/Mobile-Update-July_August.png&quot; width=&quot;1600&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  229.  
  230.  
  231.  
  232. &lt;p&gt;Expect more updates in the coming releases.&lt;/p&gt;
  233.  
  234.  
  235.  
  236. &lt;h3&gt;iOS account setup&lt;/h3&gt;
  237.  
  238.  
  239.  
  240. &lt;p&gt;The work on the iOS version is moving at full speed!&lt;/p&gt;
  241.  
  242.  
  243.  
  244. &lt;p&gt;We found ourselves in a bit of a tight spot due to the recent announcements of Apple with their new iOS 26 version, and a somewhat complete redesign of all the SwiftUI and general Human Interface Guidelines.&lt;/p&gt;
  245.  
  246.  
  247.  
  248. &lt;p&gt;When will iOS 26 be widely available and adopted?&lt;/p&gt;
  249.  
  250.  
  251.  
  252. &lt;p&gt;Will we have our iOS version of Thunderbird ready before that?&lt;/p&gt;
  253.  
  254.  
  255.  
  256. &lt;p&gt;If we build it on current iOS 18 design guidelines, how would that look on the new version?&lt;/p&gt;
  257.  
  258.  
  259.  
  260. &lt;p&gt;Will we need to update everything right after releasing the first version?&lt;/p&gt;
  261.  
  262.  
  263.  
  264. &lt;p&gt;Due to these uncertainties, we decided to focus only on the new iOS 26 user interface and be compatible with the new version right off the bat.&lt;/p&gt;
  265.  
  266.  
  267.  
  268. &lt;p&gt;We will need to test and explore carefully how that behaves on iOS 18 and prior, hoping for some available translation layers in order to guarantee compatibility.&lt;/p&gt;
  269.  
  270.  
  271.  
  272. &lt;p&gt;For now, here’s a sneak peek of the Account Setup flow for iOS!&lt;/p&gt;
  273.  
  274.  
  275.  
  276. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/09/Mobile-Update-July_August1.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3800&quot; height=&quot;1600&quot; src=&quot;https://blog.thunderbird.net/files/2025/09/Mobile-Update-July_August1.png&quot; width=&quot;1312&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  277.  
  278.  
  279.  
  280. &lt;h3&gt;Read/Unread status improvements in Android&lt;/h3&gt;
  281.  
  282.  
  283.  
  284. &lt;p&gt;As we move through an old codebase and we work hard to modernize components and layouts, it is unfortunately inevitable that we accidentally break old features or setups that are familiar to users.&lt;/p&gt;
  285.  
  286.  
  287.  
  288. &lt;p&gt;We apologize for the inconvenience, especially in this latest highlighted issue which created some discomfort when it comes to the visual distinction between read and unread messages.&lt;/p&gt;
  289.  
  290.  
  291.  
  292. &lt;p&gt;The old UI offered an option to customize the background color of those states. Even if this solution sounds like a good approach, it created multiple problems related to following system themes, light/dark mode variations, and the overall outdated implementation that needed to be removed.&lt;/p&gt;
  293.  
  294.  
  295.  
  296. &lt;p&gt;Some users were dissatisfied, and rightly so, due to the less than optimal visual distinction between those states that solely relied on background colors.&lt;/p&gt;
  297.  
  298.  
  299.  
  300. &lt;p&gt;We already improved the overall visual consistency and distinction in that area, but we’re working towards implementing a much clearer visual representation for each state that doesn’t just rely on background colors.&lt;/p&gt;
  301.  
  302.  
  303.  
  304. &lt;p&gt;We’re implementing a combination of background and foreground colors, font weight variation, and a visual indicator that specifically represents unread and new messages.&lt;/p&gt;
  305.  
  306.  
  307.  
  308. &lt;p&gt;This approach will remove any confusion and hopefully completely fix this problem.&lt;/p&gt;
  309.  
  310.  
  311.  
  312. &lt;p&gt;Thank you all those involved for your feedback and concerns, and for using the Beta version to provide early feedback and test the new updates.&lt;/p&gt;
  313.  
  314.  
  315.  
  316. &lt;h3&gt;A new release cadence&lt;/h3&gt;
  317.  
  318.  
  319.  
  320. &lt;p&gt;Starting from September, we’re switching to a faster and more consistent release cadence.&lt;/p&gt;
  321.  
  322.  
  323.  
  324. &lt;p&gt;The first week of every month we will release a new beta version, for example v13b1, followed by a new incremental beta version with improvements and fixes directly from the main branch, being released every week during that month (eg: v13b2, v13b3, etc).&lt;/p&gt;
  325.  
  326.  
  327.  
  328. &lt;p&gt;At the end of that month, the current beta, after being deemed reliable and having passed our QA steps, will be promoted as a stable version and at the same time a new beta branch will be released.&lt;/p&gt;
  329.  
  330.  
  331.  
  332. &lt;p&gt;In summary, starting from September you can expect a new stable version and a new beta cycle every month.&lt;/p&gt;
  333.  
  334.  
  335.  
  336. &lt;p&gt;Changing our cadence will allow us to expose new and work in progress features more quickly to our beta audience, and shorten the waiting time for users on the stable branch, with smaller and consistent incremental improvements.&lt;/p&gt;
  337.  
  338.  
  339.  
  340. &lt;p&gt;Cheers,&lt;/p&gt;
  341.  
  342.  
  343.  
  344. &lt;p&gt;—&lt;/p&gt;

  354. <title>The Rust Programming Language Blog: crates.io phishing campaign</title>
  355. <guid isPermaLink="true">https://blog.rust-lang.org/2025/09/12/crates-io-phishing-campaign/</guid>
  356. <link>https://blog.rust-lang.org/2025/09/12/crates-io-phishing-campaign/</link>
  357. <description>&lt;p&gt;We received multiple reports of a phishing campaign targeting crates.io users
  358. (from the &lt;code&gt;rustfoundation.dev&lt;/code&gt; domain name), mentioning a compromise of our
  359. infrastructure and asking users to authenticate to limit damage to their crates.&lt;/p&gt;
  360. &lt;p&gt;These emails are malicious and come from a domain name not controlled by  the
  361. Rust Foundation (nor the Rust Project), seemingly with the purpose of stealing
  362. your GitHub credentials. We have no evidence of a compromise of the crates.io
  363. infrastructure.&lt;/p&gt;
  364. &lt;p&gt;We are taking steps to get the domain name taken down and to monitor for
  365. suspicious activity on crates.io. Do not follow any links in these emails if you
  366. receive them, and mark them as phishing with your email provider.&lt;/p&gt;
  367. &lt;p&gt;If you have any further questions please reach out to &lt;a href=&quot;mailto:security@rust-lang.org&quot;&gt;security@rust-lang.org&lt;/a&gt;
  368. and &lt;a href=&quot;mailto:help@crates.io&quot;&gt;help@crates.io&lt;/a&gt;.&lt;/p&gt;</description>

  373. <title>Mozilla Thunderbird: State of the Thunder: Mozilla Connect Updates</title>
  374. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3783</guid>
  375. <link>https://blog.thunderbird.net/2025/09/state-of-the-thunder-mozilla-connect-updates/</link>
  376. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/09/Blog-banner-State-of-the-Thunder6-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  377. &lt;p&gt;Welcome back to the latest season of State of the Thunder! After a short break, we’re back and ready to go. Michael Ellis, our Manager of Community Programs, is helping Alessandro with hosting duties. Along with members of the Thunderbird team and community, they’re answering your questions and keeping everyone updated on our roadmap progress for our projects.&lt;/p&gt;
  378.  
  379.  
  380.  
  381. &lt;p&gt;In this episode, we’re talking about our initiatives for regular community feedback, tackling a variety of questions, and providing status updates on the top 20-ish Mozilla Connect Thunderbird suggestions. &lt;/p&gt;
  382.  
  383.  
  384.  
  385. &lt;h3&gt;Community Questions&lt;/h3&gt;
  386.  
  387.  
  388.  
  389. &lt;h4&gt;Accidental Message Order Sorting&lt;/h4&gt;
  390.  
  391.  
  392.  
  393. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Clearly the number one issue with Thunderbird that breaks for many of my clients is that if they accidentally click on a column header the sorting of the message is changed. “My messages are gone” is what I then hear all the time from my clients. It would be wonderful if the sorting of the message could be locked and not changed through such an easy operation, which often is invoked accidentally.&lt;/p&gt;
  394.  
  395.  
  396.  
  397. &lt;p&gt;Answer: This is a great usability question and a complicated one. Alessandro recommends switching to CardsView, as it’s harder to accidentally change. This one one of the reasons we implemented it! However, we can definitely explore options to lock the message order in through enterprise policies. We would want to be mindful of users who wanted to change the order. &lt;/p&gt;
  398.  
  399.  
  400.  
  401. &lt;p&gt;Michael discusses the option of a pop-up warning that could inform the user they’re about the change the message sorting order. Increased friction through a pop-up, though, as Alessandro and Jesse Miksic from the design team both point out, can cause its own issues. But this is certainly something we’ll look into more! &lt;/p&gt;
  402.  
  403.  
  404.  
  405. &lt;h4&gt;Move Focus Keyboard Shortcut&lt;/h4&gt;
  406.  
  407.  
  408.  
  409. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Could there be consideration to add a keystroke to immediately move the focus to the list of messages in the currently open mailbox? Even better if keystrokes that would automatically do this for the inbox folder or the default account.&lt;/p&gt;
  410.  
  411.  
  412.  
  413. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; Alessandro notes Thunderbird already has this ability, but it’s not super noticeable. The F6 key allows you to switch focuses between the main areas of the application. So we’re approaching this problem from two directions: implementing tabular keyboard navigation and customizable shortcuts. We don’t have an expected delivery date on the latter, but we plan to have a searchable keyboard shortcut hub. We know our interface can be a little daunting, and we’re tackling it from multiple angles.&lt;/p&gt;
  414.  
  415.  
  416.  
  417. &lt;h4&gt;Option for Simplified Thunderbird?&lt;/h4&gt;
  418.  
  419.  
  420.  
  421. &lt;p&gt;&lt;strong&gt;Question: &lt;/strong&gt;I work for a company which develops a Raspberry Pi-based computer made specific… specifically for blind consumers. Thunderbird is installed on this device by default. Many of our users are not tech-savvy. and just want a simple email client. I would love to have an easy method for removing some of the clutters with the goal of having a UI with fewer controls. Currently, users often have to press the tab key many times just to move to the list of messages in their inbox. For some users, all they really want is the message list and the list of folders, with the menu bar open, and that’s it. A bit like we once had with Outlook Express.&lt;/p&gt;
  422.  
  423.  
  424.  
  425. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; Alessandro and Ryan Sipes, our director, have talked about the need for a lighter version of Thunderbird a lot. This would help users who don’t need all the power of Thunderbird, and just want to focus on their messages (not even their folders). However, Ryan doesn’t want a separate version of Thunderbird we’d need to maintain, but to build a better usability curve into Thunderbird. Answering this question means having a Thunderbird that is simple by default, but more powerful and customizable if needed, without upsetting our current users.&lt;/p&gt;
  426.  
  427.  
  428.  
  429. &lt;p&gt;Heather Ellsworth from the community team also supports the idea of a user preference for a lighter Thunderbird. At conferences and co-working spaces, she constantly hears the requests for a slightly simpler version of Thunderbird.&lt;/p&gt;
  430.  
  431.  
  432.  
  433. &lt;h4&gt;Thunderbird PPA&lt;/h4&gt;
  434.  
  435.  
  436.  
  437. &lt;p&gt;&lt;strong&gt;Question: &lt;/strong&gt;I’m using Linux, one of the Ubuntu-derived flavors. And I have Thunderbird 128.14 ESR installed through the &lt;a href=&quot;https://launchpad.net/~mozillateam/+archive/ubuntu/ppa&quot;&gt;Mozilla Team PPA&lt;/a&gt;. I would love to know when the ESR version of 140 will be available in this PPA.&lt;/p&gt;
  438.  
  439.  
  440.  
  441. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; Heather, who works a lot with Linux packaging, takes this question. This PPA isn’t an official distribution channel for Thunderbird, which leads to some confusion. Our official Linux packages are the Snap and flatpak, and the tarball available on our website. A community member named Rico, whose handle is ricotz, maintains this PPA. In the PPA, you can click on his name to learn how to contact him for question like this.&lt;/p&gt;
  442.  
  443.  
  444.  
  445. &lt;h3&gt;Top 20-ish Mozilla Connect Posts&lt;/h3&gt;
  446.  
  447.  
  448.  
  449. &lt;p&gt;If you’ve ever posted an idea to make Thunderbird better in a blog comment, social media post, or a SUMO (&lt;a href=&quot;https://support.mozilla.org&quot;&gt;Mozilla Support&lt;/a&gt;) thread, you’ve probably been prompted to share your suggestion on &lt;a href=&quot;https://connect.mozilla.org/&quot;&gt;Mozilla Connect.&lt;/a&gt; This helps us keep our community feedback in one place, which helps our team prioritize features the community wants!&lt;/p&gt;
  450.  
  451.  
  452.  
  453. &lt;p&gt;Where we’re falling short, however, is keeping the community updated on the progress of their suggestions. With a dedicated community team, this is something we can do better! Right now, we’d like to provide a quick status update on the top 20-ish Mozilla Connect posts related to Thunderbird.&lt;/p&gt;
  454.  
  455.  
  456.  
  457. &lt;h4&gt;&lt;a href=&quot;https://connect.mozilla.org/t5/ideas/firefox-sync-for-thunderbird/idi-p/28971&quot;&gt;Sync&lt;/a&gt;&lt;/h4&gt;
  458.  
  459.  
  460.  
  461. &lt;p&gt;We implemented this in the Daily build of the desktop app last year, using a staging environment for Firefox Sync. But Firefox Sync is called Firefox Sync because it’s built for Firefox. Thunderbird profiles, in comparison, have a lot more data points. This meant we had to build something completely different. &lt;/p&gt;
  462.  
  463.  
  464.  
  465. &lt;p&gt;As we started to spin up Thunderbird Pro, we decided it made more sense to have a Thunderbird account that would manage everything, including Sync. Unfortunately, this meant a lot of delays. So Sync is still on our radar, and we hope to have it next year, barring further complications.&lt;/p&gt;
  466.

  470.  
  471.  
  472.  
  473. &lt;p&gt;Yes, we’re working on this, starting with native desktop notifications. Ideally, we want to be integrated with more Linux desktop environments through expanded native APIs.&lt;/p&gt;

  478.  
  479.  
  480.  
  481. &lt;p&gt;We already have it! You can access your account settings and customize the colors of each account.&lt;/p&gt;

  486.  
  487.  
  488.  
  489. &lt;p&gt;Already have this too. If this doesn’t happen, it’s a bug, and we’d definitely appreciate a report at &lt;a href=&quot;https://bugzilla.mozilla.org&quot;&gt;Bugzilla&lt;/a&gt;.&lt;/p&gt;
  490.

  494.  
  495.  
  496.  
  497. &lt;p&gt;We’re exploring this as both part of our increased native OS integrations and strengthening and security integrations with Thunderbird.&lt;/p&gt;
  498.

  502.  
  503.  
  504.  
  505. &lt;p&gt;We’re already adopting opt-in telemetry for an upcoming release of Thunderbird for Android, and we want to make this the default for desktop in the future. While desktop is currently opt-out, Alessandro stresses we only have a few limited telemetry probes for desktop Thunderbird. And those probes can show how the majority of users are using the app and help us avoid bad UX choices. &lt;/p&gt;

  519.  
  520.  
  521. &lt;p&gt;Currently in the works for the upcoming iOS release, with plans for support on desktop and Android. Thundermail will also come with JMAP.&lt;/p&gt;

  526.  
  527.  
  528.  
  529. &lt;p&gt;Exploring this is low on our list right now. This is both because of performance concerns and we want to be very cautious with anything concerning machine learning, which includes translation. &lt;/p&gt;

  612. &lt;p&gt;An important step for RFC implementation is for people to experiment with the
  613. implementation and give feedback, especially before stabilization.&lt;/p&gt;
  614. &lt;p&gt;If you are a feature implementer and would like your RFC to appear in this list, add a
  615. &lt;code&gt;call-for-testing&lt;/code&gt; label to your RFC along with a comment providing testing instructions and/or
  616. guidance on which aspect(s) of the feature need testing.&lt;/p&gt;
  617. &lt;ul&gt;
  618. &lt;li&gt;&lt;em&gt;No calls for testing were issued this week by
  619.  &lt;a href=&quot;https://github.com/rust-lang/rust/labels/call-for-testing&quot;&gt;Rust&lt;/a&gt;,

  623. &lt;/ul&gt;
  624. &lt;p&gt;&lt;a href=&quot;https://github.com/rust-lang/this-week-in-rust/issues&quot;&gt;Let us know&lt;/a&gt; if you would like your feature to be tracked as a part of this list.&lt;/p&gt;

  921. &lt;p&gt;Hello,&lt;/p&gt;
  922. &lt;p&gt;We are sorry you aren’t happy with the &lt;a href=&quot;https://corrode.dev/blog/async/&quot;&gt;state&lt;/a&gt; of the &lt;code&gt;async&lt;/code&gt; in the current edition of Rust. The memory ownership intuition you were meant to develop when working with single-threaded and/or parallel execution turned to be too expensive to port into our zero-cost concurrency framework, reinvented from &lt;a href=&quot;https://doc.rust-lang.org/std/pin/index.html&quot;&gt;scratch&lt;/a&gt; for the ultimate benefit to no one in particular.&lt;/p&gt;
  923. &lt;p&gt;We aren’t planning to do anything about it.&lt;/p&gt;

  939. <description>&lt;p&gt;Two months ago, we launched the first &lt;a href=&quot;https://blog.rust-lang.org/2025/06/16/rust-compiler-performance-survey-2025&quot;&gt;Rust Compiler Performance Survey&lt;/a&gt;, with the goal of helping us understand the biggest pain points of Rust developers related to build performance. It is clear that this topic is very important for the Rust community, as the survey received over 3 700 responses! We would like to thank everyone who participated in the survey, and especially those who described their workflows and challenges with an open answer. We plan to run this survey annually, so that we can observe long-term trends in Rust build performance and its perception.&lt;/p&gt;
  940. &lt;p&gt;In this post, we'll show some interesting results and insights that we got from the survey and promote work that we have already done recently or that we plan to do to improve the build performance of Rust code. If you would like to examine the complete results of the survey, you can find them &lt;a href=&quot;https://raw.githubusercontent.com/rust-lang/surveys/main/surveys/2025/compiler-performance-survey/report/compiler-performance-2025-report.pdf&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;
  941. &lt;p&gt;And now strap in, as there is a lot of data to explore! As this post is relatively long, here is an index of topics that it covers:&lt;/p&gt;

  953. Overall satisfaction&lt;/h3&gt;
  954. &lt;p&gt;To understand the overall sentiment, we asked our respondents to rate their satisfaction with their build performance, on a scale from 0 (worst) to 10 (best). The average rating was 6, with most people rating their experience with 7 out of 10:&lt;/p&gt;
  955.  
  956. &lt;div&gt;
  957.    &lt;div class=&quot;bar-chart&quot; id=&quot;satisfaction&quot;&gt;&amp;lt;noscript&amp;gt;
  958. &amp;lt;img alt=&quot;satisfaction&quot; src=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/satisfaction.png&quot; /&amp;gt;
  959. &amp;lt;/noscript&amp;gt;&lt;/div&gt;
  960.    &lt;div style=&quot;display: flex; margin-bottom: 10px;&quot;&gt;
  961.        &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/satisfaction.png&quot; target=&quot;_href_&quot; title=&quot;Download chart as PNG&quot;&gt;PNG&lt;/a&gt;]&lt;/span&gt; &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/satisfaction.svg&quot; target=&quot;_href_&quot; title=&quot;Download chart as SVG&quot;&gt;SVG&lt;/a&gt;]&lt;/span&gt;
  962.    &lt;/div&gt;
  963. &lt;/div&gt;
  964.  
  965. &lt;p&gt;To help us understand the overall build experience in more detail, we also analyzed all open answers (over a thousand of them) written by our respondents, to help us identify several recurring themes, which we will discuss in this post.&lt;/p&gt;
  966. &lt;p&gt;One thing that is clear from both the satisfaction rating and the open answers is that the build experience differs wildly across users and workflows, and it is not as clear-cut as &quot;Rust builds are slow&quot;. We actually received many positive comments about users being happy with Rust build performance, and appreciation for it being improved vastly over the past several years to the point where it stopped being a problem.&lt;/p&gt;
  967. &lt;p&gt;People also liked to compare their experience with other competing technologies. For example, many people wrote that the build performance of Rust is not worse, or is even better, than what they saw with C++. On the other hand, others noted that the build performance of languages such as Go or Zig is much better than that of Rust.&lt;/p&gt;
  968. &lt;p&gt;While it is great to see some developers being happy with the state we have today, it is clear that many people are not so lucky, and Rust's build performance limits their productivity. Around 45% respondents who answered that they are no longer using Rust said that at least one of the reasons why they stopped were long compile times.&lt;/p&gt;
  969. &lt;p&gt;In our survey we received a lot of feedback pointing out real issues and challenges in several areas of build performance, which is what we will focus on in this post.&lt;/p&gt;
  970. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#important-workflows&quot;&gt;&lt;/a&gt;
  971. Important workflows&lt;/h3&gt;
  972. &lt;p&gt;The challenges that Rust developers experience with build performance are not always as simple as the compiler itself being slow. There are many diverse workflows with competing trade-offs, and optimizing build performance for them might require completely different solutions. Some approaches for improving build performance can also be quite unintuitive. For example, stabilizing certain language features could help remove the need for certain build scripts or proc macros, and thus speed up compilation across the Rust ecosystem. You can watch &lt;a href=&quot;https://www.youtube.com/watch?v=-jy4HaNEJCo&quot;&gt;this talk&lt;/a&gt; from RustWeek about build performance to learn more.&lt;/p&gt;
  973. &lt;p&gt;It is difficult to enumerate all possible build workflows, but we at least tried to ask about workflows that we assumed are common and could limit the productivity of Rust developers the most:&lt;/p&gt;
  974.  
  975. &lt;div&gt;
  976.    &lt;div class=&quot;matrix-chart&quot; id=&quot;limiting-workflows&quot;&gt;&amp;lt;noscript&amp;gt;
  977. &amp;lt;img alt=&quot;limiting-workflows&quot; src=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/limiting-workflows.png&quot; /&amp;gt;
  978. &amp;lt;/noscript&amp;gt;&lt;/div&gt;
  979.    &lt;div style=&quot;display: flex; margin-bottom: 10px;&quot;&gt;
  980.        &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/limiting-workflows.png&quot; target=&quot;_href_&quot; title=&quot;Download chart as PNG&quot;&gt;PNG&lt;/a&gt;]&lt;/span&gt; &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/limiting-workflows.svg&quot; target=&quot;_href_&quot; title=&quot;Download chart as SVG&quot;&gt;SVG&lt;/a&gt;]&lt;/span&gt;
  981.    &lt;/div&gt;
  982. &lt;/div&gt;
  983.  
  984. &lt;p&gt;We can see that all the workflows that we asked about cause significant problems to at least a fraction of the respondents, but some of them more so than others. To gain more information about the specific problems that developers face, we also asked a more detailed, follow-up question:&lt;/p&gt;
  985.  
  986. &lt;div&gt;
  987.    &lt;div class=&quot;matrix-chart&quot; id=&quot;problems&quot;&gt;&amp;lt;noscript&amp;gt;
  988. &amp;lt;img alt=&quot;problems&quot; src=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/problems.png&quot; /&amp;gt;
  989. &amp;lt;/noscript&amp;gt;&lt;/div&gt;
  990.    &lt;div style=&quot;display: flex; margin-bottom: 10px;&quot;&gt;
  991.        &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/problems.png&quot; target=&quot;_href_&quot; title=&quot;Download chart as PNG&quot;&gt;PNG&lt;/a&gt;]&lt;/span&gt; &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/problems.svg&quot; target=&quot;_href_&quot; title=&quot;Download chart as SVG&quot;&gt;SVG&lt;/a&gt;]&lt;/span&gt;
  992.    &lt;/div&gt;
  993. &lt;/div&gt;
  994.  
  995. &lt;p&gt;Based on the answers to these two questions and other experiences shared in the open answers, we identified three groups of workflows that we will discuss next:&lt;/p&gt;
  996. &lt;ul&gt;
  997. &lt;li&gt;Incremental rebuilds after making a small change&lt;/li&gt;
  998. &lt;li&gt;Type checking using &lt;code&gt;cargo check&lt;/code&gt; or with a code editor&lt;/li&gt;
  999. &lt;li&gt;Clean, from-scratch builds, including CI builds&lt;/li&gt;
  1000. &lt;/ul&gt;
  1001. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#incremental-rebuilds&quot;&gt;&lt;/a&gt;
  1002. Incremental rebuilds&lt;/h4&gt;
  1003. &lt;p&gt;Waiting too long for an incremental rebuild after making a small source code change was by far the most common complaint in the open answers that we received, and it was also the most common problem that respondents said they struggle with. Based on our respondents' answers, this comes down to three main bottlenecks:&lt;/p&gt;
  1004. &lt;ul&gt;
  1005. &lt;li&gt;&lt;strong&gt;Changes in workspaces trigger unnecessary rebuilds.&lt;/strong&gt; If you modify a crate in a workspace that has several dependent crates and perform a rebuild, all those dependent crates will currently have to be recompiled. This can cause a lot of unnecessary work and dramatically increase the latency of rebuilds in large (or deep) workspaces. We have some ideas about how to improve this workflow, such as the &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/relink-dont-rebuild.html&quot;&gt;&quot;Relink, don't rebuild&quot;&lt;/a&gt; proposal, but these are currently in a very experimental stage.&lt;/li&gt;
  1006. &lt;li&gt;&lt;strong&gt;The linking phase is too slow.&lt;/strong&gt; This was a very common complaint, and it is indeed a real issue, because unlike the rest of the compilation process, linking is always performed &quot;from scratch&quot;. The Rust compiler usually delegates linking to an external/system linker, so its performance is not completely within our hands. However, we are attempting to switch to faster linkers by default. For example, the most popular target (&lt;code&gt;x86_64-unknown-linux-gnu&lt;/code&gt;) will very soon switch to the &lt;a href=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable&quot;&gt;LLD linker&lt;/a&gt;, which provides significant performance wins. Long-term, it is possible that some linkers (e.g. &lt;a href=&quot;https://github.com/davidlattimore/wild&quot;&gt;wild&lt;/a&gt;) will allow us to perform even linking incrementally.&lt;/li&gt;
  1007. &lt;li&gt;&lt;strong&gt;Incremental rebuild of a single crate is too slow.&lt;/strong&gt; The performance of this workflow depends on the cleverness of the incremental engine of the Rust compiler. While it is already very sophisticated, there are some parts of the compilation process that are not incremental yet or that are not cached in an optimal way. For example, expansion of derive proc macros is not currently cached, although work is underway to &lt;a href=&quot;https://github.com/rust-lang/rust/pull/145354&quot;&gt;change that&lt;/a&gt;.&lt;/li&gt;
  1008. &lt;/ul&gt;
  1009. &lt;p&gt;Several users have mentioned that they would like to see Rust perform hot-patching (such as the &lt;code&gt;subsecond&lt;/code&gt; system used by the Dioxus UI framework or similar approaches used e.g. by the Bevy game engine). While these hot-patching systems are very exciting and can produce truly near-instant rebuild times for specialized use-cases, it should be noted that they also come with many limitations and edge-cases, and it does not seem that a solution that would allow hot-patching to work in a robust way has been found yet.&lt;/p&gt;
  1010. &lt;p&gt;To gauge how long is the typical rebuild latency, we asked our respondents to pick a single Rust project that they work on and which causes them to struggle with build times the most, and tell us how long they have to wait for it to be rebuilt after making a code change.&lt;/p&gt;
  1011.

  1018.    &lt;/div&gt;
  1019. &lt;/div&gt;
  1020.  
  1021. &lt;p&gt;Even though many developers do not actually experience this latency after each code change, as they consume results of type checking or inline annotations in their code editor, the fact that 55% of respondents have to wait more than ten seconds for a rebuild is far from ideal.&lt;/p&gt;
  1022. &lt;p&gt;If we partition these results based on answers to other questions, it is clear that the rebuild times depend a lot on the size of the project:&lt;/p&gt;

  1042. &lt;/div&gt;
  1043.  
  1044. &lt;p&gt;We would love to get to a point where the time needed to rebuild a Rust project is dependent primarily on the amount of performed code changes, rather than on the size of the codebase, but clearly we are not there yet.&lt;/p&gt;
  1045. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#type-checking-and-ide-performance&quot;&gt;&lt;/a&gt;
  1046. Type checking and IDE performance&lt;/h4&gt;
  1047. &lt;p&gt;Approximately 60% of respondents say that they use &lt;code&gt;cargo&lt;/code&gt; terminal commands to type check, build or test their code, with &lt;code&gt;cargo check&lt;/code&gt; being the most commonly used command performed after each code change:&lt;/p&gt;
  1048.  
  1049. &lt;div&gt;
  1050.    &lt;div class=&quot;matrix-chart&quot; id=&quot;cargo-commands&quot;&gt;&amp;lt;noscript&amp;gt;
  1051. &amp;lt;img alt=&quot;cargo-commands&quot; src=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/cargo-commands.png&quot; /&amp;gt;
  1052. &amp;lt;/noscript&amp;gt;&lt;/div&gt;
  1053.    &lt;div style=&quot;display: flex; margin-bottom: 10px;&quot;&gt;
  1054.        &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/cargo-commands.png&quot; target=&quot;_href_&quot; title=&quot;Download chart as PNG&quot;&gt;PNG&lt;/a&gt;]&lt;/span&gt; &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/cargo-commands.svg&quot; target=&quot;_href_&quot; title=&quot;Download chart as SVG&quot;&gt;SVG&lt;/a&gt;]&lt;/span&gt;
  1055.    &lt;/div&gt;
  1056. &lt;/div&gt;
  1057.  
  1058. &lt;p&gt;While the performance of &lt;code&gt;cargo check&lt;/code&gt; does not seem to be as big of a blocker as e.g. incremental rebuilds, it also causes some pain points. One of the most common ones present in the survey responses is the fact that &lt;code&gt;cargo check&lt;/code&gt; does not share the build cache with &lt;code&gt;cargo build&lt;/code&gt;. This causes additional compilation to happen when you run e.g. &lt;code&gt;cargo check&lt;/code&gt; several times to find all type errors, and when it succeeds, you follow up with &lt;code&gt;cargo build&lt;/code&gt; to actually produce a built artifact. This workflow is an example of competing trade-offs, because sharing the build cache between these two commands by unifying them more would likely make &lt;code&gt;cargo check&lt;/code&gt; itself slightly slower, which might be undesirable to some users. It is possible that we might be able to find some middle ground to improve the status quo though. You can follow updates to this work in &lt;a href=&quot;https://github.com/rust-lang/cargo/issues/3501&quot;&gt;this issue&lt;/a&gt;.&lt;/p&gt;
  1059. &lt;p&gt;A related aspect is the latency of type checking in code editors and IDEs. Around 87% of respondents say that they use inline annotations in their editor as the primary mechanism of inspecting compiler errors, and around 33% of them consider waiting for these annotations to be a big blocker. In the open answers, we also received many reports of Rust Analyzer's performance and memory usage being a limiting factor.&lt;/p&gt;
  1060. &lt;p&gt;The maintainers of Rust Analyzer are working hard on improving its performance. Its caching system is &lt;a href=&quot;https://www.youtube.com/watch?v=tn6qwhMNBJo&quot;&gt;being improved&lt;/a&gt; to reduce analysis latency, the distributed builds of the editor are now &lt;a href=&quot;https://github.com/rust-lang/rust-analyzer/pull/19582&quot;&gt;optimized with PGO&lt;/a&gt;, which provided 15-20% performance wins, and work is underway to integrate the compiler's &lt;a href=&quot;https://github.com/rust-lang/rust-analyzer/pull/20329&quot;&gt;new trait solver&lt;/a&gt; into Rust Analyzer, which could eventually also result in increased performance.&lt;/p&gt;
  1061. &lt;p&gt;More than 35% users said that they consider the IDE and Cargo &lt;a href=&quot;https://github.com/rust-lang/cargo/issues/4282&quot;&gt;blocking one another&lt;/a&gt; to be a big problem. There is an existing workaround for this, where you can configure Rust Analyzer to use a different target directory than Cargo, at the cost of increased disk space usage. We realized that this workaround has not been documented in a very visible way, so we added it to the &lt;a href=&quot;https://rust-analyzer.github.io/book/faq.html#rust-analyzer-and-cargo-compete-over-the-build-lock&quot;&gt;FAQ section&lt;/a&gt; of the Rust Analyzer book.&lt;/p&gt;
  1062. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#clean-and-ci-builds&quot;&gt;&lt;/a&gt;
  1063. Clean and CI builds&lt;/h4&gt;
  1064. &lt;p&gt;Around 20% of participants responded that clean builds are a significant blocker for them. In order to improve their performance, you can try a recently introduced experimental Cargo and compiler option called &lt;a href=&quot;https://blog.rust-lang.org/inside-rust/2025/07/15/call-for-testing-hint-mostly-unused&quot;&gt;&lt;code&gt;hint-mostly-unused&lt;/code&gt;&lt;/a&gt;, which can in certain situations help improve the performance of clean builds, particularly if your dependencies contain a lot of code that might not actually be used by your crate(s).&lt;/p&gt;
  1065. &lt;p&gt;One area where clean builds might happen often is Continuous Integration (CI). 1495 respondents said that they use CI to build Rust code, and around 25% of them consider its performance to be a big blocker for them. However, almost 36% of respondents who consider CI build performance to be a big issue said that they do not use any caching in CI, which we found surprising. One explanation might be that the generated artifacts (the &lt;code&gt;target&lt;/code&gt; directory) is too large for effective caching, and runs into usage limits of CI providers, which is something that we saw mentioned repeatedly in the open answers section. We have recently introduced an experimental Cargo and compiler option called &lt;a href=&quot;https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#no-embed-metadata&quot;&gt;&lt;code&gt;-Zembed-metadata&lt;/code&gt;&lt;/a&gt; that is designed to reduce the size of the &lt;code&gt;target&lt;/code&gt; directories, and work is also underway to regularly &lt;a href=&quot;https://github.com/rust-lang/cargo/issues/13136&quot;&gt;garbage collect&lt;/a&gt; them. This might help with the disk space usage issue somewhat in the future.&lt;/p&gt;
  1066. &lt;p&gt;One additional way to significantly reduce disk usage is to reduce the amount of generated debug information, which brings us to the next section.&lt;/p&gt;
  1067. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#debug-information&quot;&gt;&lt;/a&gt;
  1068. Debug information&lt;/h3&gt;
  1069. &lt;p&gt;The default Cargo &lt;code&gt;dev&lt;/code&gt; profile generates full debug information (debuginfo) both for workspace crates and also all dependencies. This enables stepping through code with a debugger, but it also increases disk usage of the &lt;code&gt;target&lt;/code&gt; directory, and crucially it makes compilation and linking slower. This effect can be quite large, as our benchmarks show a possible improvement of &lt;a href=&quot;https://perf.rust-lang.org/compare.html?start=0d0f4eac8b98133e5da6d3604d86a8f3b5a67844&amp;amp;end=71ea9a0cacc3473c7b6852c17453259f74635c62&amp;amp;stat=cycles%3Au&amp;amp;doc=false&amp;amp;check=false&amp;amp;opt=false&quot;&gt;2-30% in cycle counts&lt;/a&gt; if we reduce the debuginfo level to &lt;code&gt;line-tables-only&lt;/code&gt; (which only generates enough debuginfo for backtraces to work), and the improvements are &lt;a href=&quot;https://perf.rust-lang.org/compare.html?start=bea625f3275e3c897dc965ed97a1d19ef7831f01&amp;amp;end=87c3e1ecd699573f7cb4c9074b8727956bd37a74&amp;amp;stat=cycles%3Au&amp;amp;check=false&amp;amp;opt=false&amp;amp;doc=false&quot;&gt;even larger&lt;/a&gt; if we disable debuginfo generation completely&lt;sup class=&quot;footnote-reference&quot; id=&quot;fr-lld-1&quot;&gt;&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#fn-lld&quot;&gt;1&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
  1070. &lt;p&gt;However, if Rust developers debug their code after most builds, then this cost might be justified. We thus asked them how often they use a debugger to debug their Rust code:&lt;/p&gt;
  1071.  
  1072. &lt;div&gt;
  1073.    &lt;div class=&quot;bar-chart&quot; id=&quot;debugger&quot;&gt;&amp;lt;noscript&amp;gt;

  1078.    &lt;/div&gt;
  1079. &lt;/div&gt;
  1080.  
  1081. &lt;p&gt;Based on these results, it seems that the respondents of our survey do not actually use a debugger all that much&lt;sup class=&quot;footnote-reference&quot; id=&quot;fr-why-not-debug-1&quot;&gt;&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#fn-why-not-debug&quot;&gt;2&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
  1082. &lt;p&gt;However, when we asked people if they require debuginfo to be generated by default, the responses were much less clear-cut:&lt;/p&gt;

  1090.    &lt;/div&gt;
  1091. &lt;/div&gt;
  1092.  
  1093. &lt;p&gt;This is the problem with changing defaults: it is challenging to improve the workflows of one user without regressing the workflow of another.  For completeness, here are the answers to the previous question partitioned on the answer to the &quot;How often do you use a debugger&quot; question:&lt;/p&gt;
  1094.

  1101.    &lt;/div&gt;
  1102. &lt;/div&gt;
  1103.  
  1104. &lt;p&gt;It was surprising for us to see that around a quarter of respondents who (almost) never use a debugger still want to have full debuginfo generated by default.&lt;/p&gt;
  1105. &lt;p&gt;Of course, you can always disable debuginfo manually to improve your build performance, but not everyone knows about that option, and defaults matter a lot. The Cargo team is &lt;a href=&quot;https://github.com/rust-lang/cargo/issues/15931&quot;&gt;considering&lt;/a&gt; ways of changing the status quo, for example by reducing the level of generated debug information in the &lt;code&gt;dev&lt;/code&gt; profile, and introducing a new built-in profile designed for debugging.&lt;/p&gt;
  1106. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#workarounds-for-improving-build-performance&quot;&gt;&lt;/a&gt;
  1107. Workarounds for improving build performance&lt;/h3&gt;
  1108. &lt;p&gt;Build performance of Rust is affected by many different aspects, including the configuration of the build system (usually Cargo) and the Rust compiler, but also the organization of Rust crates and used source code patterns. There are thus several approaches that can be used to improve build performance by either using different configuration options or restructuring source code. We asked our respondents if they are even aware of such possibilities, whether they have tried them and how effective they were:&lt;/p&gt;
  1109.

  1116.    &lt;/div&gt;
  1117. &lt;/div&gt;
  1118.  
  1119. &lt;p&gt;It seems that the most popular (and effective) mechanisms for improving build performance are reducing the number of dependencies and their activated features, and splitting larger crates into smaller crates. The most common way of improving build performance without making source code changes seems to be the usage of an alternative linker. It seems that especially the mold and LLD linkers are very popular:&lt;/p&gt;

  1127.    &lt;/div&gt;
  1128. &lt;/div&gt;
  1129.  
  1130. &lt;p&gt;We have good news here! The most popular &lt;code&gt;x86_64-unknown-linux-gnu&lt;/code&gt; Linux target will start using the LLD linker in the next Rust stable release, resulting in faster link times &lt;em&gt;by default&lt;/em&gt;. Over time, we will be able to evaluate how disruptive is this change to the overall Rust ecosystem, and whether we could e.g. switch to a different (even faster) linker.&lt;/p&gt;
  1131. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#build-performance-guide&quot;&gt;&lt;/a&gt;
  1132. Build performance guide&lt;/h4&gt;
  1133. &lt;p&gt;We were surprised by the relatively large number of users who were unaware of some approaches for improving compilation times, in particular those that are very easy to try and typically do not require source code changes (such as reducing debuginfo or using a different linker or a codegen backend). Furthermore, almost 42% of respondents have not tried to use &lt;em&gt;any&lt;/em&gt; mechanism for improving build performance whatsoever. While this is not totally unexpected, as some of these mechanisms require using the nightly toolchain or making non-trivial changes to source code, we think that one the reasons is also simply that Rust developers might not know about these mechanisms being available. In the open answers, several people also noted that they would appreciate if there was some sort of official guidance from the Rust Project about such mechanisms for improving compile times.&lt;/p&gt;
  1134. &lt;p&gt;It should be noted that the mechanisms that we asked about are in fact workarounds that present various trade-offs, and these should always be carefully considered. Several people have expressed dissatisfaction with some of these workarounds in the open answers, as they find it unacceptable to modify their code (which could sometimes result e.g. in increased maintenance costs or worse runtime performance) just to achieve reasonable compile times. Nevertheless, these workarounds can still be incredibly useful in some cases.&lt;/p&gt;
  1135. &lt;p&gt;The feedback that we received shows that it might be beneficial to spread awareness of these mechanisms in the Rust community more, as some of them can make a really large difference in build performance, but also to candidly explain the trade-offs that they introduce. Even though several great resources that cover this topic already exist online, we decided to create an &lt;a href=&quot;https://github.com/rust-lang/cargo/pull/15924&quot;&gt;official guide&lt;/a&gt; for optimizing build performance (currently work-in-progress), which will likely be hosted in the &lt;a href=&quot;https://doc.rust-lang.org/cargo&quot;&gt;Cargo book&lt;/a&gt;. The aim of this guide is to increase the awareness of various mechanisms for improving build performance, and also provide a framework for evaluating their trade-offs.&lt;/p&gt;
  1136. &lt;p&gt;Our long-standing goal is to make compilation so fast that similar workarounds will not be necessary anymore for the vast majority of use-cases. However, there is no free lunch, and the combination of Rust's strong type system guarantees, its compilation model and also heavy focus on runtime performance often go against very fast (re)build performance, and might require usage of at least some workarounds. We hope that this guide will help Rust developers learn about them and evaluate them for their specific use-case.&lt;/p&gt;
  1137. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#understanding-why-builds-are-slow&quot;&gt;&lt;/a&gt;
  1138. Understanding why builds are slow&lt;/h3&gt;
  1139. &lt;p&gt;When Rust developers experience slow builds, it can be challenging to identify where exactly is the compilation process spending time, and what could be the bottleneck. It seems that only very few Rust developers leverage tools for profiling their builds:&lt;/p&gt;
  1140.  
  1141. &lt;div&gt;
  1142.    &lt;div class=&quot;matrix-chart&quot; id=&quot;profiling-tools&quot;&gt;&amp;lt;noscript&amp;gt;
  1143. &amp;lt;img alt=&quot;profiling-tools&quot; src=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/profiling-tools.png&quot; /&amp;gt;
  1144. &amp;lt;/noscript&amp;gt;&lt;/div&gt;
  1145.    &lt;div style=&quot;display: flex; margin-bottom: 10px;&quot;&gt;
  1146.        &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/profiling-tools.png&quot; target=&quot;_href_&quot; title=&quot;Download chart as PNG&quot;&gt;PNG&lt;/a&gt;]&lt;/span&gt; &lt;span&gt;[&lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/profiling-tools.svg&quot; target=&quot;_href_&quot; title=&quot;Download chart as SVG&quot;&gt;SVG&lt;/a&gt;]&lt;/span&gt;
  1147.    &lt;/div&gt;
  1148. &lt;/div&gt;
  1149.  
  1150. &lt;p&gt;This hardly comes as a surprise. There are currently not that many ways of intuitively understanding the performance characteristics of Cargo and &lt;code&gt;rustc&lt;/code&gt;. Some tools offer only a limited amount of information (e.g. &lt;code&gt;cargo build --timings&lt;/code&gt;), and the output of others (e.g. &lt;code&gt;-Zself-profile&lt;/code&gt;) is very hard to interpret without knowledge of the compiler internals.&lt;/p&gt;
  1151. &lt;p&gt;To slightly improve this situation, we have recently added support for displaying &lt;a href=&quot;https://github.com/rust-lang/cargo/pull/15923&quot;&gt;link times&lt;/a&gt; to the &lt;code&gt;cargo build --timings&lt;/code&gt; output, to provide more information about the possible bottleneck in crate compilation (note this feature has not been stabilized yet).&lt;/p&gt;
  1152. &lt;p&gt;Long-term, it would be great to have tooling that could help Rust developers diagnose compilation bottlenecks in their crates without them having to understand how the compiler works. For example, it could help answer questions such as &quot;Which code had to be recompiled after a given source change&quot; or &quot;Which (proc) macros take the longest time to expand or produce the largest output&quot;, and ideally even offer some actionable suggestions. We plan to work on such tooling, but it will take time to manifest.&lt;/p&gt;
  1153. &lt;p&gt;One approach that could help Rust compiler contributors understand why are Rust (re)builds slow &quot;in the wild&quot; is the opt-in &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h1/metrics-initiative.html&quot;&gt;compilation metrics collection initiative&lt;/a&gt;.&lt;/p&gt;
  1154. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#what-s-next&quot;&gt;&lt;/a&gt;
  1155. What's next&lt;/h3&gt;
  1156. &lt;p&gt;There are more interesting things in the survey results, for example how do answers to selected questions differ based on the used operating system. You can examine the full results in the &lt;a href=&quot;https://raw.githubusercontent.com/rust-lang/surveys/main/surveys/2025/compiler-performance-survey/report/compiler-performance-2025-report.pdf&quot;&gt;full report PDF&lt;/a&gt;.&lt;/p&gt;
  1157. &lt;p&gt;We would like to thank once more everyone who has participated in our survey. It helped us understand which workflows are the most painful for Rust developers, and especially the open answers provided several great suggestions that we tried to act upon.&lt;/p&gt;
  1158. &lt;p&gt;Even though the Rust compiler is getting increasingly faster every year, we understand that many Rust developers require truly significant improvements to improve their productivity, rather than &quot;just&quot; incremental performance wins. Our goal for the future is to finally stabilize long-standing initiatives that could improve build performance a lot, such as the &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/production-ready-cranelift.html&quot;&gt;Cranelift codegen backend&lt;/a&gt; or the &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/parallel-front-end.html&quot;&gt;parallel compiler frontend&lt;/a&gt;. One such initiative (using a &lt;a href=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable&quot;&gt;faster linker by default&lt;/a&gt;) will finally land soon, but the fact that it took many years shows how difficult it is to make such large cutting changes to the compilation process.&lt;/p&gt;
  1159. &lt;p&gt;There are other ambitious ideas for reducing (re)build times, such as &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/relink-dont-rebuild.html&quot;&gt;avoiding unnecessary workspace rebuilds&lt;/a&gt; or e.g. using some form of &lt;a href=&quot;https://github.com/davidlattimore/wild&quot;&gt;incremental linking&lt;/a&gt;, but these will require a lot of work and design discussions.&lt;/p&gt;
  1160. &lt;p&gt;We know that some people are wondering why it takes so much time to achieve progress in improving the build performance of Rust. The answer is relatively simple. These changes require a lot of work, domain knowledge (that takes a relatively long time to acquire) and many discussions and code reviews, and the pool of people that have time and motivation to work on them or review these changes is very limited. Current compiler maintainers and contributors (many of whom work on the compiler as volunteers, without any funding) work very hard to keep up with maintaining the compiler and keeping it working with the high-quality bar that Rust developers expect, across many targets, platforms and operating systems. Introducing large structural changes, which are likely needed to reach massive performance improvements, would require a lot of concentrated effort and funding.&lt;/p&gt;
  1161.  
  1162.  
  1163.  
  1164. &lt;section class=&quot;footnotes&quot;&gt;
  1165. &lt;ol class=&quot;footnotes-list&quot;&gt;
  1166. &lt;li id=&quot;fn-lld&quot;&gt;
  1167. &lt;p&gt;This benchmark was already performed using the fast LLD linker. If a slower linker was used, the build time wins would likely be even larger. &lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#fr-lld-1&quot;&gt;↩&lt;/a&gt;&lt;/p&gt;
  1168. &lt;/li&gt;
  1169. &lt;li id=&quot;fn-why-not-debug&quot;&gt;
  1170. &lt;p&gt;Potentially because of the strong invariants upheld by the Rust type system, and partly also because the Rust debugging experience might not be optimal for many users, which is a feedback that we received in the &lt;a href=&quot;https://blog.rust-lang.org/2025/02/13/2024-State-Of-Rust-Survey-results/#challenges&quot;&gt;State of Rust 2024 survey&lt;/a&gt;. &lt;a href=&quot;https://blog.rust-lang.org/2025/09/10/rust-compiler-performance-survey-2025-results/#fr-why-not-debug-1&quot;&gt;↩&lt;/a&gt;&lt;/p&gt;

  1181. <description>&lt;p&gt;The promise of an open and competitive internet hangs in the balance. From the future of AI agents to the underappreciated role of browsers and browser engines, the technological landscape continues to evolve. Getting the regulatory and enforcement backdrop right is critical: from competition bills in Congress to the EU’s DMA, the stakes for innovation, privacy and consumer choice have never been higher.&lt;/p&gt;

  1193. <link>https://blog.mozilla.org/en/firefox/shake-to-summarize/</link>
  1194. <description>&lt;p&gt;On mobile, browsing often means quick checks on small screens, squeezed in between everything else you’re doing. We built Shake to Summarize on iOS to give you a clear summary with one move. That way, you can get what you need more easily and keep going.&lt;/p&gt;
  1195.  
  1196.  
  1197.  
  1198. &lt;h3&gt;&lt;strong&gt;How it works&lt;/strong&gt;&lt;/h3&gt;
  1199.  
  1200.  
  1201.  
  1202. &lt;p&gt;Whether you just want the recipe, need to know something fast, or want to see if a long read is worth the time, Shake to Summarize gives you the key takeaways in seconds. To activate it, you can:&lt;br /&gt;&lt;/p&gt;
  1203.  
  1204.  
  1205.  
  1206. &lt;ul&gt;
  1207. &lt;li&gt;&lt;strong&gt;Shake your device&lt;/strong&gt;.&lt;/li&gt;
  1208.  
  1209.  
  1210.  
  1211. &lt;li&gt;&lt;strong&gt;Tap the thunderbolt icon&lt;/strong&gt; in the address bar.&lt;/li&gt;
  1212.  
  1213.  
  1214.  
  1215. &lt;li&gt;Or, from the menu, &lt;strong&gt;tap three dots &amp;gt; Summarize Page&lt;/strong&gt;.&lt;/li&gt;
  1216. &lt;/ul&gt;
  1217.  
  1218.  
  1219.  
  1220. &lt;p&gt;&lt;/p&gt;
  1221.  
  1222.  
  1223.  
  1224. &lt;figure class=&quot;wp-block-video&quot;&gt;&lt;video controls=&quot;controls&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/09/s2s-secretsprinkle-S2S-1.mov&quot;&gt;&lt;/video&gt;&lt;/figure&gt;
  1225.  
  1226.  
  1227.  
  1228. &lt;p&gt;&lt;/p&gt;
  1229.  
  1230.  
  1231.  
  1232. &lt;p&gt;The feature works on webpages with fewer than 5,000 words. (Learn more about content you can summarize &lt;a href=&quot;https://support.mozilla.org/en-US/kb/summarize-pages-ios&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;here&lt;/a&gt;.) &lt;/p&gt;
  1233.  
  1234.  
  1235.  
  1236. &lt;p&gt;Here’s an example of a summary:&lt;/p&gt;
  1237.  
  1238.  
  1239.  
  1240. &lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;Three smartphone screens showing Firefox article summarized with Apple Intelligence on translation updates for Chinese, Japanese, and Korean users.&quot; class=&quot;wp-image-81609&quot; height=&quot;610&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/08/shake-to-summarize-summaries-1024x610.png&quot; width=&quot;1024&quot; /&gt;&lt;/figure&gt;
  1241.  
  1242.  
  1243.  
  1244. &lt;p&gt;If you have an iPhone 15 Pro or later with iOS 26+, the summary is created on your device using Apple Intelligence. On other devices with earlier iOS versions, the page text is sent securely to Mozilla cloud-based AI, which creates the summary and sends it back. &lt;/p&gt;
  1245.  
  1246.  
  1247.  
  1248. &lt;h3&gt;&lt;strong&gt;Rollout starts Sept. 9&lt;/strong&gt;&lt;/h3&gt;
  1249.  
  1250.  
  1251.  
  1252. &lt;p&gt;Shake to Summarize starts rolling out this week in the U.S. for English-language Firefox iOS users, then expands from there. &lt;/p&gt;
  1253.  
  1254.  
  1255.  
  1256. &lt;p&gt;You’ll see a prompt the first time you come across content that can be summarized, and you can turn the feature on or off in settings anytime.&lt;/p&gt;
  1257.  
  1258.  
  1259.  
  1260. &lt;h3&gt;&lt;strong&gt;Designed for user choice&lt;/strong&gt;&lt;/h3&gt;
  1261.  
  1262.  
  1263.  
  1264. &lt;p&gt;Sometimes you want the whole story. Sometimes you just need the highlights. Firefox mobile gives you both and leaves the choice to you. &lt;/p&gt;
  1265.  
  1266.  
  1267.  
  1268. &lt;p&gt;Let us &lt;a href=&quot;https://connect.mozilla.org/&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;know what you think&lt;/a&gt;&lt;strong&gt; &lt;/strong&gt;once you give it a try.&lt;/p&gt;

  1284. <title>The Mozilla Blog: Defending an open web: What the Google search ruling means for the future</title>
  1285. <guid isPermaLink="false">https://blog.mozilla.org/?p=81607</guid>
  1286. <link>https://blog.mozilla.org/en/mozilla/internet-policy/defending-an-open-web/</link>
  1287. <description>&lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;The Mozilla logo in green on a black background&quot; class=&quot;wp-image-78766&quot; height=&quot;576&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/03/Mozilla-Blog-Thumbnail@2x-1024x576.png&quot; width=&quot;1024&quot; /&gt;&lt;/figure&gt;
  1288.  
  1289.  
  1290.  
  1291. &lt;p&gt;Last week, Judge Amit Mehta issued a ruling in the remedies proceedings of the &lt;em&gt;U.S. v. Google LLC &lt;/em&gt;search case. Among the issues addressed, one key aspect that stood out for us was the court’s ruling on Google’s search agreements. &lt;/p&gt;
  1292.  
  1293.  
  1294.  
  1295. &lt;p&gt;The Court ordered changes to Google’s search agreements to give browsers more flexibility. Under the court’s decision, Google cannot restrict browsers from defaulting to or offering different search engines / generative AI services. They can also not prevent browsers from promoting these services.   &lt;/p&gt;
  1296.  
  1297.  
  1298.  
  1299. &lt;p&gt;Crucially, the Court considered but ultimately rejected a proposed ban on search payments to small, independent browsers like Firefox. If the ban had been enforced, it would have made it harder for independent browsers to compete, effectively reducing competition in the browser market. &lt;/p&gt;
  1300.  
  1301.  
  1302.  
  1303. &lt;p&gt;In his reasoning, Judge Mehta cited Mozilla’s &lt;a href=&quot;https://blog.mozilla.org/en/mozilla/internet-policy/google-search-deals-and-browser-choice/&quot;&gt;testimony&lt;/a&gt;, recognizing that banning payments to smaller browsers would harm innovation, competition, and consumers, and would threaten the pro-competitive role of Mozilla in the ecosystem. Ensuring that Mozilla’s Gecko — the only independent browser engine left — can continue to compete with Google and Apple is &lt;a href=&quot;https://blog.mozilla.org/en/mozilla/internet-policy/google-remedies-browsers/&quot;&gt;vital for the future of the open web.&lt;/a&gt;&lt;/p&gt;
  1304.  
  1305.  
  1306.  
  1307. &lt;p&gt;The court also required a range of data sharing remedies — narrowing the scope of those proposed by the Department of Justice and State Attorneys General, while broadening their access. As Mozilla has discovered first-hand through previous antitrust cases and the implementation of the EU Digital Markets Act, ensuring that such remedies are effective in restoring competition requires careful attention and monitoring. Careful thought must also be given to protecting user privacy and security.&lt;/p&gt;
  1308.  
  1309.  
  1310.  
  1311. &lt;p&gt;It will also be critical to ensure that these data remedies avoid simply transferring power from one tech giant to another — particularly given the focus on facilitating greater search competition through AI providers.  &lt;/p&gt;
  1312.  
  1313.

  1315. &lt;p&gt;This balance is something we’ve stressed throughout the trial. True competition in search starts with a healthy marketplace, one where small and large companies can compete on merit, where consumers have choice, and where the best new products, features, and ideas have a chance. &lt;/p&gt;

We’ve historically met market and regulatory shifts with creativity and care. Each moment has helped us grow and discover new ways to live out our mission, and we’re invigorated about the path forward. &lt;/p&gt;

  1325. <title>Wladimir Palant: A look at a P2P camera (LookCam app)</title>

  1327. <link>https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/</link>
  1328. <description>&lt;p&gt;I’ve got my hands on an internet-connected camera and decided to take a closer look, having already read about security issues with similar cameras. What I found far exceeded my expectations: fake access controls, bogus protocol encryption, completely unprotected cloud uploads and firmware riddled with security flaws. One could even say that these cameras are Murphy’s Law turned solid: everything that could be done wrong has been done wrong here. While there is considerable prior research on these and similar cameras that outlines some of the flaws, I felt that the combination of severe flaws is reason enough to publish an article of my own.&lt;/p&gt;
  1329. &lt;p&gt;My findings should apply to any camera that can be managed via the LookCam app. This includes cameras meant to be used with less popular apps of the same developer: tcam, CloudWayCam, VDP, AIBoxcam, IP System. Note that the LookCamPro app, while visually very similar, is technically quite different. It also uses the PPPP protocol for low-level communication but otherwise doesn’t seem to be related, and the corresponding devices are unlikely to suffer from the same flaws.&lt;/p&gt;
  1330. &lt;figure&gt;&lt;img alt=&quot;A graphic with the LookCam logo in the middle. Around it are arranged five devices with the respective camera locations marked: a radio clock, a power outlet, a light switch, a USB charger, a bulb socket.&quot; class=&quot;article-image&quot; height=&quot;423&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/devices.jpg&quot; width=&quot;600&quot; /&gt;&lt;/figure&gt;
  1331.  
  1332. &lt;p&gt;There seems to be little chance that things will improve with these cameras. I have no way of contacting either the hardware vendors or the developers behind the LookCam app. In fact, it looks like masking their identity was done on purpose here. But even if I could contact them, the cameras lack an update mechanism for their firmware. So fixing the devices already sold is impossible.&lt;/p&gt;
  1333. &lt;p&gt;I have no way of knowing how many of these cameras exist. The LookCam app is currently listed with almost 1.5 million downloads on Google Play however. An iPhone and a Windows version of the app are also available but no public statistics exist here.&lt;/p&gt;

  1353.  &lt;/ul&gt;
  1354. &lt;/nav&gt;
  1355. &lt;/div&gt;
  1356.  
  1357. &lt;h3&gt;The highlights&lt;/h3&gt;
  1358. &lt;p&gt;The camera cannot be easily isolated from unauthorized access. It can either function as a WiFi access point, but setting a WiFi password isn’t possible. Or it can connect to an existing network, and then it will insist on being connected to the internet. If internet access is removed the camera will go into a reboot loop. So you have the choice of letting anybody in the vicinity access this camera or allowing it to be accessed from the internet.&lt;/p&gt;
  1359. &lt;p&gt;The communication of this camera is largely unencrypted. The underlying PPPP protocol supports “encryption” which is better described as obfuscation, but the LookCam app almost never makes use of it. Not that it would be of much help, the proprietary encryption algorithms being developed without any understanding of cryptography. These rely on static encryption keys which are trivially extracted from the app but should be easy enough to deduce even from merely observing some traffic.&lt;/p&gt;
  1360. &lt;p&gt;The camera firmware is riddled with buffer overflow issues which should be trivial to turn into arbitrary code execution. Protection mechanisms like DEP or ASLR might have been a hurdle but these are disabled. And while the app allows you to set an access password, the firmware doesn’t really enforce it. So access without knowing the password can be accomplished simply by modifying the app to skip the password checks.&lt;/p&gt;
  1361. &lt;p&gt;The only thing preventing complete compromise of any camera is the “secret” device ID which has to be known in order to establish a connection. And by “secret” I mean that device IDs can generally be enumerated but they are “secured” with a five letter verification code. Unlike with some similar cameras, the algorithm used to generate the verification code isn’t public knowledge yet. So somebody wishing to compromise as many cameras as possible would need to either guess the algorithm or guess the verification codes by trying out all possible combinations. I suspect that both approaches are viable.&lt;/p&gt;
  1362. &lt;p&gt;And while the devices themselves have access passwords which a future firmware version could in theory start verifying, the corresponding cloud service has no authentication beyond knowledge of the device ID. So any recordings uploaded to the cloud are accessible even if the device itself isn’t. Even if the camera owner hasn’t paid for the cloud service, anyone could book it for them if they know the device ID. The cloud configuration is managed by the server, so making the camera upload its recordings doesn’t require device access.&lt;/p&gt;
  1363. &lt;h3&gt;The hardware&lt;/h3&gt;
  1364. &lt;p&gt;Most cameras connecting to the LookCam app are being marketed as “spy cam” or “nanny cam.” These are made to look like radio clocks, USB chargers, bulb sockets, smoke detectors, even wall outlets. Most of the time their pretended functionality really works. In addition they have an almost invisible pinhole camera that can create remarkably good recordings. I’ve seen prices ranging from US$40 to hundreds of dollars.&lt;/p&gt;
  1365. &lt;p&gt;The marketing spin says that these cameras are meant to detect when your house is being robbed. Or maybe they allow you to observe your baby while it is in the next room. Of course, in reality people are far more inventive in their use of tiny cameras. Students &lt;a href=&quot;https://theconversation.com/students-are-using-smart-spy-technology-to-cheat-in-exams-59241&quot;&gt;discovered them for cheating in exams&lt;/a&gt;. Gamblers use them to &lt;a href=&quot;https://www.wired.com/story/miniature-camera-poker-cheating/&quot;&gt;get an advantage at card games&lt;/a&gt;. And then there is of course the matter of non-consentual video recordings. So next time you stay somewhere where you don’t quite trust the host you might want to search for “LookCam” on YouTube, just to get an idea of how to recognize such devices.&lt;/p&gt;
  1366. &lt;p&gt;The camera I had was based on the &lt;a href=&quot;http://anyka.net/en/productInfo.aspx?id=123&quot;&gt;Anyka AK39Ev330 hardware platform&lt;/a&gt;, essentially an ARM CPU with an attached pinhole camera. Presumably, other cameras connecting to the LookCam app are similar, even though there are some provisions for hardware differences in the firmware. The device looked very convincing, its main giveaway being unexpected heat development.&lt;/p&gt;
  1367. &lt;p&gt;All LookCam cameras I’ve seen were strictly noname devices, it is unclear who builds them. Given the variety of competing form factors I suspect that a number of hardware vendors are involved. Maybe there is one vendor producing the raw camera kit and several others who package it within the respective casings.&lt;/p&gt;
  1368. &lt;h3&gt;The LookCam app&lt;/h3&gt;
  1369. &lt;p&gt;The LookCam app can manage a number of cameras. Some people demonstrating the app on YouTube had around 50 of them, though I suspect that these are camera sellers and not regular users.&lt;/p&gt;
  1370. &lt;figure&gt;&lt;img alt=&quot;App screenshot, a screen titled “My Device.” It lists a number of cameras with stills on the left side. The cameras are titled something like G000001NRLXW. At the bottom of the screen are the options Video (selected), Photo, Files and More.&quot; class=&quot;article-image&quot; height=&quot;480&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/screenshot.png&quot; width=&quot;240&quot; /&gt;&amp;lt;figcaption&amp;gt;
  1371. LookCam app as seen in the example screenshot
  1372. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1373.  
  1374. &lt;p&gt;While each camera can be given a custom name, its unique ID is always visible as well. For example, the first camera listed in the screenshot above has the ID GHBB-000001-NRLXW which the apps shortens into G000001NRLXW. Here GHBB is the device prefix: LookCam supports a number of these but only BHCC, FHBB and GHBB seem to exist in reality (abbreviated as B, F and G respectively). 000001 is the device number, each prefix can theoretically support a million devices. The final part is a five-letter verification code: NRLXW. This one has to be known for the device connection to succeed, it makes enumerating device IDs more difficult.&lt;/p&gt;
  1375. &lt;p&gt;Out of the box, the device is in access point mode: it provides a WiFi access point with the device ID used as wireless network name. You can connect to that access point, and LookCam will be able to find the camera via a network broadcast, allowing you to configure it. You might be inclined to leave the camera in access point mode but it is impossible to set a WiFi password. This means that anybody in the vicinity can connect to this WiFi network and access the camera through it. So there is no way around configuring the camera to connect to your network.&lt;/p&gt;
  1376. &lt;p&gt;Once the camera is connected to your network the P2P “magic” happens. LookCam app can still find the camera via a network broadcast. But it can also establish a connection when you are not on the same network. In other words: the camera can be accessed from the internet, assuming that someone knows its device ID.&lt;/p&gt;
  1377. &lt;p&gt;Exposing the camera to internet-based attacks might not be something that you want, with it being in principle perfectly capable of writing its recordings to an SD card. But if you deny it access to the internet (e.g. via a firewall rule) the camera will try to contact its server, fail, panic and reboot. It will keep rebooting until it receives a response from the server.&lt;/p&gt;
  1378. &lt;p&gt;One thing to note is also: the device ID is displayed in pretty much every screen of this app. So when users share screenshots or videos of the app (which they do often) they will inevitably expose the ID of their camera, allowing anyone in the world to connect to it. I’ve seen very few cases of people censoring the device ID, clearly most of them aren’t aware that it is sensitive information. The LookCam app definitely isn’t communicating that it is.&lt;/p&gt;
  1379. &lt;h3&gt;The PPPP protocol&lt;/h3&gt;
  1380. &lt;h4&gt;The basics&lt;/h4&gt;
  1381. &lt;p&gt;How can LookCam establish a connection to the camera having only its device ID? The app uses the PPPP protocol developed by the Chinese company CS2 Network. Supposedly, in 2019 CS2 Network had 300 customers with 20 million devices in total. This company supplies its customers with a code library and the corresponding server code which the customers can run as a black box. The idea of the protocol is providing an equivalent of the TCP protocol which implicitly locates a device by its ID and connects to it.&lt;/p&gt;
  1382. &lt;figure&gt;&lt;img alt=&quot;Screenshot of a presentation slide divided in two with TCP on the left and P2P on the right. Left side shows the calls to establish a TCP connection and write data, right side equivalent function calls with PPC_ prefix&quot; class=&quot;article-image&quot; height=&quot;267&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/slide_tcp_p2p.png&quot; width=&quot;475&quot; /&gt;&amp;lt;figcaption&amp;gt;
  1383. Slide from a CS2 Network sales pitch
  1384. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1385.  
  1386. &lt;p&gt;&lt;em&gt;Side note&lt;/em&gt;: Whoever designed this protocol didn’t really understand TCP. For example, they tried to replicate the fault tolerance of TCP. But instead of making retransmissions an underlying protocol feature there are dozens of different (not duplicated but really different) retransmission loops throughout the library. Where TCP tries to detect network congestions and back off the PPPP protocol will send even more retransmitted messages, rendering suboptimal connections completely unusable.&lt;/p&gt;
  1387. &lt;p&gt;Despite being marketed as Peer-to-Peer (P2P) this protocol relies on centralized servers. Each device prefix is associated with a set of three servers, this being the protocol designers’ idea of high-availability infrastructure. Devices regularly send messages to all three servers, making sure that these are aware of the device’s IP address. When the LookCam app (client) wants to connect to a device, it also contacts all three servers to get the device’s IP address.&lt;/p&gt;
  1388. &lt;figure&gt;&lt;img alt=&quot;Screenshot of a presentation slide titled “High Availability Architecture.” The text says: Redundant P2P Servers, Flexible and Expandable Relay Servers&quot; class=&quot;article-image&quot; height=&quot;209&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/slide_high_availability.png&quot; width=&quot;362&quot; /&gt;&amp;lt;figcaption&amp;gt;
  1389. Slide from a CS2 Network sales pitch
  1390. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1391.  
  1392. &lt;p&gt;The P2P part is the fact that device and client try to establish a direct connection instead of relaying all communication via a central server. The complicating factor here are firewalls which usually disallow direct connections. The developers didn’t like established approaches like &lt;a href=&quot;https://en.wikipedia.org/wiki/Universal_Plug_and_Play&quot;&gt;Universal Plug and Play (UPnP)&lt;/a&gt;, probably because these are often disabled for security reasons. So they used a trick called &lt;a href=&quot;https://en.wikipedia.org/wiki/UDP_hole_punching&quot;&gt;UDP hole punching&lt;/a&gt;. This involves guessing which port the firewall assigned to outgoing UDP traffic and then communicating with that port, so that the firewall considers incoming packets a response to previously sent UDP packets and allows them through.&lt;/p&gt;
  1393. &lt;p&gt;Does that always work? That’s doubtful. So the PPPP protocol allows for relay servers to be used as fallback, forwarding traffic from and to the device. But this direct communication presumably succeeds often enough to keep the traffic on PPPP servers low, saving costs.&lt;/p&gt;
  1394. &lt;p&gt;The FHBB and GHBB device prefixes are handled by the same set of servers, named the “mykj” network in the LookCam app internally. Same string appears in the name of the main class as well, indicating that it likely refers to the company developing the app. This seems to be a short form of “Meiyuan Keji,” a company name that translates as “Dollar Technology.” I couldn’t find any further information on this company however.&lt;/p&gt;
  1395. &lt;p&gt;The BHCC device prefix is handled by a different set of servers that the app calls the “hekai” network. The corresponding devices appear to be marketed in China only.&lt;/p&gt;
  1396. &lt;h4&gt;The “encryption”&lt;/h4&gt;
  1397. &lt;p&gt;With potentially very sensitive data being transmitted one would hope that the data is safely encrypted in transit. The TCP protocol outsources this task to additional layers like TLS. The PPPP protocol on the other hand has built-in “encryption,” in fact even two different encryption mechanisms.&lt;/p&gt;
  1398. &lt;p&gt;First there is the blanket encryption of all transmitted messages. The corresponding function is aptly named &lt;code&gt;P2P_Proprietary_Encrypt&lt;/code&gt; and it is in fact a very proprietary encryption algorithm. To my untrained eye there are a few issues with it:&lt;/p&gt;
  1399. &lt;ul&gt;
  1400. &lt;li&gt;It is optional, with many networks choosing not to use it (like all networks supported by LookCam).&lt;/li&gt;
  1401. &lt;li&gt;When present, the encryption key is part of the “init string” which is hardcoded in the app. It is trivial to extract from the application, even a file viewer will do if you know what to look for.&lt;/li&gt;
  1402. &lt;li&gt;Even if the encryption key weren’t easily extracted, it is mashed into four bytes which become the effective key. So there are merely four billion possible keys.&lt;/li&gt;
  1403. &lt;li&gt;Even if it weren’t possible to just go through all possible encryption keys, the algorithm can be trivially attacked via a &lt;a href=&quot;https://en.wikipedia.org/wiki/Known-plaintext_attack&quot;&gt;known-plaintext attack&lt;/a&gt;. It’s sometimes even possible to deduce the effective key by passively observing a single four bytes &lt;code&gt;MSG_HELLO&lt;/code&gt; message (it is known that the first four bytes message sent to port 32100 has the plaintext &lt;code&gt;F1 00 00 00&lt;/code&gt;).&lt;/li&gt;
  1404. &lt;/ul&gt;
  1405. &lt;p&gt;In addition to that, some messages get special treatment. For example, the &lt;code&gt;MSG_REPORT_SESSION_READY&lt;/code&gt; message is generally encrypted via &lt;code&gt;P2P_Proprietary_Encrypt&lt;/code&gt; function with a key that is hardcoded in the CS2 library and has the same value in every app I checked.&lt;/p&gt;
  1406. &lt;p&gt;Some messages employ a different encryption method. In case of the networks supported by LookCam it is only the &lt;code&gt;MSG_DEV_LGN_CRC&lt;/code&gt; message (device registering with the server) that is used instead of the plaintext &lt;code&gt;MSG_DEV_LGN&lt;/code&gt; message. As this message is sent by the device, the corresponding encryption key is only present in the device firmware, not in the application. I didn’t bother checking whether the server would still accept the unencrypted &lt;code&gt;MSG_DEV_LGN&lt;/code&gt; message.&lt;/p&gt;
  1407. &lt;p&gt;The encryption function responsible here is &lt;code&gt;PPPP_CRCEnc&lt;/code&gt;. No, this isn’t a cyclic redundancy check (CRC). It’s rather an encryption function that will extend the plaintext by a four bytes padding. The decryptor will validate the padding, presumably that’s the reason for the name.&lt;/p&gt;
  1408. &lt;p&gt;Of course, this still doesn’t make it an authenticated encryption scheme, yet the &lt;a href=&quot;https://en.wikipedia.org/wiki/Padding_oracle_attack&quot;&gt;padding oracle attack&lt;/a&gt; is really the least of its worries. While there is a complicated selection approach, it effectively results in a sequence of bytes that the plaintext is XOR’ed with. &lt;em&gt;Same&lt;/em&gt; sequence for every single message being encrypted in this way. Wikipedia has the following to say on the &lt;a href=&quot;https://en.wikipedia.org/wiki/XOR_cipher#Use_and_security&quot;&gt;security of XOR ciphers&lt;/a&gt;:&lt;/p&gt;
  1409. &lt;blockquote&gt;
  1410. &lt;p&gt;By itself, using a constant repeating key, a simple XOR cipher can trivially be broken using frequency analysis. If the content of any message can be guessed or otherwise known then the key can be revealed.&lt;/p&gt;&lt;/blockquote&gt;
  1411. &lt;p&gt;Well, yes. That’s what we have here.&lt;/p&gt;
  1412. &lt;p&gt;It’s doubtful that any of these encryption algorithms can deter even a barely determined attacker. But a blanket encryption with &lt;code&gt;P2P_Proprietary_Encrypt&lt;/code&gt; (which LookCam doesn’t enable) would have three effects:&lt;/p&gt;
  1413. &lt;ol&gt;
  1414. &lt;li&gt;Network traffic is obfuscated, making the contents of transmitted messages not immediately obvious.&lt;/li&gt;
  1415. &lt;li&gt;Vulnerable devices cannot be discovered on the local network using the &lt;a href=&quot;https://github.com/pmarrapese/iot/tree/master/p2p/lansearch&quot;&gt;script developed by Paul Marrapese&lt;/a&gt;. This script relies on devices responding to an unencrypted search request.&lt;/li&gt;
  1416. &lt;li&gt;P2P servers can no longer be discovered easily and won’t show up on Shodan for example. This discovery method relies on servers responding to an unencrypted &lt;code&gt;MSG_HELLO&lt;/code&gt; message.&lt;/li&gt;
  1417. &lt;/ol&gt;
  1418. &lt;h4&gt;The threat model&lt;/h4&gt;
  1419. &lt;p&gt;It is obvious that the designers of the PPPP protocol don’t understand cryptography, yet for some reason they don’t want to use established solutions either. It cannot even be about performance because AES is supported in hardware on these devices. But why for example this strange choice of encrypting a particular message while keeping the encryption of highly private data optional? Turns out, this is due to the threat model used by the PPPP protocol designers.&lt;/p&gt;
  1420. &lt;figure&gt;&lt;img alt=&quot;Screenshot of a presentation slide containing yellow text: Malicious hacker can make thousands of Fake Device by writing a software program (As you know, the cost may be less than 1 USD), however. It then continues with red text: It may cause thousands pcs of your product to malfunction, thus cost hundred thousands.&quot; class=&quot;article-image&quot; height=&quot;221&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/slide_fake_devices.png&quot; width=&quot;380&quot; /&gt;&amp;lt;figcaption&amp;gt;
  1421. Slide from a CS2 Network sales pitch
  1422. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1423.  
  1424. &lt;p&gt;As a CS2 Network presentation deck shows, their threat model isn’t concerned about data leaks. The concern is rather denial-of-service attacks caused by registering fake devices. And that’s why this one message enjoys additional encryption. Not that I really understand the concern here, since the supposed hacker would still have to generate valid device IDs somehow. And if they can do that – well, them bringing the server down should really be the least concern.&lt;/p&gt;
  1425. &lt;p&gt;But wait, there is another security layer here!&lt;/p&gt;
  1426. &lt;figure&gt;&lt;img alt=&quot;Screenshot of a presentation slide titled “Encrypted P2P Server IP String.” The text says: The encrypted string is given to platform owner only. Without correct string, Fake Device can’t use P2P API to reach P2P Server. The API require encrypt P2P Server IP String, but not raw IP String.&quot; class=&quot;article-image&quot; height=&quot;281&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/slide_init_string.png&quot; width=&quot;383&quot; /&gt;&amp;lt;figcaption&amp;gt;

  1428. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1429.  
  1430. &lt;p&gt;This is about the “init string” already mentioned in the context of encryption keys above. It also contains the IP addresses of the servers, mildly obfuscated. While these were “given to platform owner only,” these are necessarily contained in the LookCam app:&lt;/p&gt;
  1431. &lt;figure&gt;&lt;img alt=&quot;Screenshot of a source code listing with four fields g_hekai_init_string, g_mykj_init_string, g_ppcs_init_string, g_rtos_init_string. All four values are strings consisting of upper-case letters.&quot; class=&quot;article-image&quot; height=&quot;132&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/initstrings.png&quot; width=&quot;607&quot; /&gt;&lt;/figure&gt;
  1432.  
  1433. &lt;p&gt;Some other apps contain dozens of such init strings, allowing them to deal with many different networks. So the threat model of the PPPP protocol cannot imagine someone extracting the “encrypted P2P server IP string” from the app. It cannot imagine someone reverse engineering the (trivial) obfuscation used here. And it definitely cannot imagine someone reverse engineering the protocol, so that they can communicate with the servers via “raw IP string” instead of their obfuscated one. &lt;em&gt;Note&lt;/em&gt;: The latter has happened on several documented occasions already, e.g. &lt;a href=&quot;https://www.elastic.co/security-labs/storm-on-the-horizon#building-a-p2p-client&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;
  1434. &lt;p&gt;These underlying assumptions become even more obvious on this slide:&lt;/p&gt;
  1435. &lt;figure&gt;&lt;img alt=&quot;Screenshot of a presentation slide titled “Worry about security?” The text says: Super Device can not spy any data it Relayed (No API for this)&quot; class=&quot;article-image&quot; height=&quot;188&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/slide_spying.png&quot; width=&quot;412&quot; /&gt;&amp;lt;figcaption&amp;gt;

  1437. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1438.  
  1439. &lt;p&gt;Yes, the only imaginable way to read out network data is via the API of their library. With a threat model like this, it isn’t surprising that the protocol makes all the wrong choices security-wise.&lt;/p&gt;
  1440. &lt;h3&gt;The firmware&lt;/h3&gt;
  1441. &lt;p&gt;Once a connection is etablished the LookCam app and the camera will exchange JSON-encoded messages like the following:&lt;/p&gt;
  1442. &lt;div class=&quot;highlight&quot;&gt;&lt;pre class=&quot;chroma&quot; tabindex=&quot;0&quot;&gt;&lt;code class=&quot;language-json&quot;&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;&lt;span class=&quot;p&quot;&gt;{&lt;/span&gt;
  1443. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;  &lt;span class=&quot;nt&quot;&gt;&quot;cmd&quot;&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;:&lt;/span&gt; &lt;span class=&quot;s2&quot;&gt;&quot;LoginDev&quot;&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;,&lt;/span&gt;
  1444. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;  &lt;span class=&quot;nt&quot;&gt;&quot;pwd&quot;&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;:&lt;/span&gt; &lt;span class=&quot;s2&quot;&gt;&quot;123456&quot;&lt;/span&gt;
  1445. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;&lt;span class=&quot;p&quot;&gt;}&lt;/span&gt;
  1446. &lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;A &lt;a href=&quot;https://www.dcs.warwick.ac.uk/~fenghao/files/hidden_camera.pdf&quot;&gt;paper from the Warwick University&lt;/a&gt; already took a closer look at the firmware and discovered something surprising. The LookCam app will send a &lt;code&gt;LoginDev&lt;/code&gt; command like above to check whether the correct access password is being used for the device. But sending this command is entirely optional, and the firmware will happily accept other commands without a “login”!&lt;/p&gt;
  1447. &lt;p&gt;The LookCam app will also send the access password along with every other command yet this password isn’t checked by the firmware either. I tried adding a trivial modification to the LookCam app which made it ignore the result of the &lt;code&gt;LoginDev&lt;/code&gt; command. And this in fact bypassed the authentication completely, allowing me to access my camera despite a wrong password.&lt;/p&gt;
  1448. &lt;p&gt;I could also confirm their finding that the &lt;code&gt;DownloadFile&lt;/code&gt; command will read arbitrary files, allowing me to extract the firmware of my camera with the approach described in the paper. They even describe a trivial Remote Code Execution vulnerability which I also found in my firmware: that firmware often relies on running shell commands for tasks that could be easily done in its C language code.&lt;/p&gt;
  1449. &lt;p&gt;This clearly isn’t the only Remote Code Execution vulnerability however. Here is some fairly typical code for this firmware:&lt;/p&gt;
  1450. &lt;div class=&quot;highlight&quot;&gt;&lt;pre class=&quot;chroma&quot; tabindex=&quot;0&quot;&gt;&lt;code class=&quot;language-c&quot;&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;&lt;span class=&quot;kt&quot;&gt;char&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;mi&quot;&gt;256&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;]&lt;/span&gt; &lt;span class=&quot;n&quot;&gt;buf&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;;&lt;/span&gt;
  1451. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;&lt;span class=&quot;kt&quot;&gt;char&lt;/span&gt; &lt;span class=&quot;o&quot;&gt;*&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;cmd&lt;/span&gt; &lt;span class=&quot;o&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;nf&quot;&gt;cJSON_GetObjectItem&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;request&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;s&quot;&gt;&quot;cmd&quot;&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;)&lt;/span&gt;&lt;span class=&quot;o&quot;&gt;-&amp;gt;&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;valuestring&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;;&lt;/span&gt;
  1452. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;&lt;span class=&quot;nf&quot;&gt;memset&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;buf&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;mi&quot;&gt;0&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;k&quot;&gt;sizeof&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;buf&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;));&lt;/span&gt;
  1453. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;line&quot;&gt;&lt;span class=&quot;cl&quot;&gt;&lt;span class=&quot;nf&quot;&gt;memcpy&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;buf&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;n&quot;&gt;cmd&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;nf&quot;&gt;strlen&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;cmd&lt;/span&gt;&lt;span class=&quot;p&quot;&gt;));&lt;/span&gt;
  1454. &lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;This code copies a string (pointlessly but this isn’t the issue here). It completely fails to consider the size of the target buffer, going by the size of the incoming data instead. So any command larger than 255 bytes will cause a &lt;a href=&quot;https://en.wikipedia.org/wiki/Buffer_overflow&quot;&gt;buffer overflow&lt;/a&gt;. And there is no stack canary here, Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) are disabled, so nothing prevents this buffer overflow from being turned into Remote Code Execution.&lt;/p&gt;
  1455. &lt;p&gt;Finally, I’ve discovered that the &lt;code&gt;searchWiFiList&lt;/code&gt; command will produce the list of WiFi networks visible to the camera. These by itself often already allow a good guess as to where the camera is located. In combination with a &lt;a href=&quot;https://developers.google.com/maps/documentation/geolocation/overview&quot;&gt;geolocation service&lt;/a&gt; these will typically narrow down the camera’s position to a radius of only a few dozen meters.&lt;/p&gt;
  1456. &lt;p&gt;The only complication here: most geolocation services require not the network names but the MAC addresses of the access points. The MAC addresses aren’t part of the response data however. But: &lt;code&gt;searchWiFiList&lt;/code&gt; works by running &lt;code&gt;iwlist&lt;/code&gt; shell command and storing the complete output in &lt;code&gt;/tmp/wifi_scan.txt&lt;/code&gt; file. It reads this file but does not remove it. This means that the file can subsequently be downloaded via &lt;code&gt;DownloadFile&lt;/code&gt; command (allows reading arbitrary files as mentioned above) and that one contains full data including MAC addresses of all access points. So somebody who happened to learn the device ID can not only access the video stream but also find out where exactly this footage is being recorded.&lt;/p&gt;
  1457. &lt;p&gt;The camera I’ve been looking at is running firmware version 2023-11-22. Is there a newer version, maybe one that fixes the password checks or the already published Remote Code Execution vulnerability? I have no idea. If the firmware for these cameras is available somewhere online then I cannot find it. I’ve also been looking for some kind of update functionality in these devices. But there is only a generic script from the Anyka SDK which isn’t usable for anyone other than maybe the hardware vendor.&lt;/p&gt;
  1458. &lt;h3&gt;The cloud&lt;/h3&gt;
  1459. &lt;p&gt;When looking at the firmware I noticed some code uploading 5 MiB data chunks to &lt;code&gt;api.l040z.com&lt;/code&gt; (or &lt;code&gt;apicn.l040z.com&lt;/code&gt; if you happen to own a &lt;code&gt;BHCC&lt;/code&gt; device). Now uploading &lt;em&gt;exactly&lt;/em&gt; 5 MiB is weird (this size is hardcoded) but inspecting the LookCam app confirmed it: this is cloud functionality, and the firmware regularly uploads videos in this way. At least it does that when cloud functionality is enabled.&lt;/p&gt;
  1460. &lt;p&gt;First thing worth noting: while the cloud server uses regular HTTP rather than some exotic protocol, all connections to it are generally unencrypted. The firmware simply lacks a TLS library it could use, and so the server doesn’t bother with supporting TLS. Meaning for example: if you happen to use their cloud functionality your ISP better be very trustworthy because it can see all the data your camera sends to the LookCam cloud. In fact, your ISP could even run its own “cloud server” and the camera will happily send your recorded videos to it.&lt;/p&gt;
  1461. &lt;p&gt;Anyone dare a guess what the app developers mean by “financial-grade encryption scheme” here? Is it worse or better than military-grade encryption?&lt;/p&gt;
  1462. &lt;figure&gt;&lt;img alt=&quot;Screenshot containing two text sections. The section above it titled “Safe storage” and reads: The video data is stored in the cloud, even if the device is offline or lost. Can also view previous recordings. The section below is titled “Privacy double encryption” and reads: Using financial-grade encryption scheme, data is transmitted from data to Transfer data from transfer data from transfer.&quot; class=&quot;article-image&quot; height=&quot;452&quot; src=&quot;https://palant.info/2025/09/08/a-look-at-a-p2p-camera-lookcam-app/cloud.png&quot; width=&quot;385&quot; /&gt;&amp;lt;figcaption&amp;gt;
  1463. Screenshot from the LookCam app
  1464. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  1465.  
  1466. &lt;p&gt;Second interesting finding: the cloud server has no authentication whatsoever. The camera only needs to know its device ID when uploading to the cloud. And the LookCam app – well, any cloud-related requests here also require device ID only. If somebody happens to learn your device ID they will gain full access to your cloud storage.&lt;/p&gt;
  1467. &lt;p&gt;Now you might think that you can simply skip paying for the cloud service which, depending on the package you book, can come for as much as $40 per month. But this doesn’t mean that you are on the safe side because you aren’t the one controlling the cloud functionality on your device, the cloud server is. Every time the device boots up it sends a request to &lt;code&gt;http://api.l040z.com/camera/signurl&lt;/code&gt; and the response tells it whether cloud functionality needs to be enabled.&lt;/p&gt;
  1468. &lt;p&gt;So if LookCam developers decide that they want to see what your camera is doing (or if Chinese authorities become interested in that), they can always adjust that server response and the camera will start uploading video snapshots. You won’t even notice anything because the LookCam app checks cloud configuration by requesting &lt;code&gt;http://api.l040z.com/app/cloudConfig&lt;/code&gt; which can remain unchanged.&lt;/p&gt;
  1469. &lt;p&gt;And they aren’t the only ones who can enable the cloud functionality of your device. Anybody who happens to know your device ID can buy a cloud package for it. This way they can get access to your video recordings without ever accessing your device directly. And you will only notice the cloud functionality being active if you happen to go to the corresponding tab in the LookCam app.&lt;/p&gt;
  1470. &lt;h3&gt;How safe are device IDs?&lt;/h3&gt;
  1471. &lt;p&gt;Now that you are aware of device IDs being highly sensitive data, you certainly won’t upload screenshots containing them to social media. Does that mean that your camera is safe because nobody other than you knows its ID?&lt;/p&gt;
  1472. &lt;p&gt;The short answer is: you don’t know that. First of all, you simply don’t know who already has your device ID. Did the shop that sold you the camera write the ID down? Did they maybe record a sales pitch featuring your camera before they sold it to you? Did somebody notice your camera’s device ID show up in the list of WiFi networks when it was running in access point mode? Did anybody coming to your home run a &lt;a href=&quot;https://github.com/pmarrapese/iot/tree/master/p2p/lansearch&quot;&gt;script to discover PPPP devices on the network&lt;/a&gt;? Yes, all of that might seem unlikely, yet it should be reason enough to wonder whether your camera’s recordings are really as private as they should be.&lt;/p&gt;
  1473. &lt;p&gt;Then there is the issue of unencrypted data transfers. Whenever you connect to your camera from outside your home network the LookCam app will send all data unencrypted – including the device ID. Do you do that when connected to public WiFi? At work? In a vacation home? You don’t know who else is listening.&lt;/p&gt;
  1474. &lt;p&gt;And finally there is the matter of verification codes which are the only mechanism preventing somebody from enumerating all device IDs. How difficult would it be to guess a verification code? Verification codes seem to use 22 letters (all Latin uppercase letters but A, I, O, Q). With five letters this means around 5 million possible combinations. According to Paul Marrapese &lt;a href=&quot;https://media.defcon.org/DEF%20CON%2028/DEF%20CON%20Safe%20Mode%20presentations/DEF%20CON%20Safe%20Mode%20-%20Paul%20Marrapese%20-%20Abusing%20P2P%20to%20Hack%203%20Million%20Cameras%20Ain%27t%20Nobody%20Got%20Time%20for%20NAT.pdf&quot;&gt;PPPP servers don’t implement rate limiting&lt;/a&gt; (page 33), making trying out all these combinations perfectly realistic – maybe not for all possible device IDs but definitely for some.&lt;/p&gt;
  1475. &lt;p&gt;But that resource-intensive approach is only necessary as long as the algorithm used to generate verification codes is a secret. Yet we have to assume that at least CS2 Network’s 300 customers have access to that algorithm, given that their server software somehow validates device IDs. Are they all trustworthy? How much would it cost to become a “customer” simply in order to learn that algorithm?&lt;/p&gt;
  1476. &lt;p&gt;And even if we are willing to assume that CS2 Network runs proper background checks to ensure that their algorithm remains a secret: how difficult would it be to guess that algorithm? I found a number of device IDs online, and my primitive analysis of their verification codes indicates that these aren’t distributed equally. There is a noticeable affinity for certain prime numbers, so the algorithm behind them is likely a similar hack job as the other CS2 Network algorithms, throwing in mathematical operations and table lookups semi-randomly to make things look complicated. How long would this approach hold if somebody with actual cryptanalysis knowledge decided to figure this out?&lt;/p&gt;
  1477. &lt;h3&gt;Recommendations&lt;/h3&gt;
  1478. &lt;p&gt;So if you happen to own one of these cameras, what does all this mean to you? Even if you never disclosed the camera’s device ID yourself, you cannot rely on it staying a secret. And this means that whatever your camera is recording is no longer private.&lt;/p&gt;
  1479. &lt;p&gt;Are you using it as a security camera? Your security camera might now inform potential thieves of the stuff that you have standing around and the times when you leave home. It will also let them know where exactly you live.&lt;/p&gt;
  1480. &lt;p&gt;Are you using it to keep an eye on your child? Just… don’t. Even if you think that you yourself have a right to violate your child’s privacy, you really don’t want anybody else to watch.&lt;/p&gt;
  1481. &lt;p&gt;And even if you “have nothing to hide”: somebody could compromise the camera in order to hack other devices on your network or to simply make it part of a botnet. Such things &lt;a href=&quot;https://www.bleepingcomputer.com/news/security/hackers-target-critical-zero-day-vulnerability-in-ptz-cameras/&quot;&gt;happened before&lt;/a&gt;, many times actually.&lt;/p&gt;
  1482. &lt;p&gt;So the best solution is to dispose of this camera ASAP. Don’t sell it please because this only moves the problem to the next person. The main question is: how do you know that the camera you get instead will do better? I can only think of one indicator: if you want to access the camera from outside your network it should involve explicit setup steps, likely changing router configuration. The camera shouldn’t just expose itself to the internet automatically.&lt;/p&gt;
  1483. &lt;p&gt;But if you actually paid hundreds of dollars for that camera and dumping it isn’t an option: running it in a safe manner is complicated. As I mentioned already, simply blocking internet access for the camera won’t work. This can be worked around but it’s complex enough to be not worth doing. You should be better off by installing a &lt;a href=&quot;https://github.com/Nemobi/Anyka/&quot;&gt;custom firmware&lt;/a&gt;. I haven’t tried it but at least this one looks like somebody actually thought about security.&lt;/p&gt;
  1484. &lt;h3&gt;Further reading&lt;/h3&gt;
  1485. &lt;p&gt;As far as I am aware, the first research on the PPPP protocol was &lt;a href=&quot;https://hacked.camera/&quot;&gt;published by Paul Marrapese in 2019&lt;/a&gt;. He found a number of vulnerabilities, including one brand of cameras shipping their algorithm to generate verification codes with their client application. Knowing this algorithm, device IDs could be enumerated easily. Paul used this flaw to display the locations of millions of affected devices. His DEF CON talk is linked from the website and well worth watching.&lt;/p&gt;
  1486. &lt;p&gt;&lt;strong&gt;Edit&lt;/strong&gt; (2025-09-15): I was wrong, there is at the very least &lt;a href=&quot;https://www.slideshare.net/slideshow/iot-security-is-a-nightmare-but-what-is-the-real-risk/65213457&quot;&gt;this early analysis of the protocol by Zoltán Balázs (2016)&lt;/a&gt; (starting at page 29) and &lt;a href=&quot;https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html&quot;&gt;some research into a particular brand of PPPP-based cameras by Pierre Kim (2017)&lt;/a&gt;.&lt;/p&gt;
  1487. &lt;p&gt;A &lt;a href=&quot;https://www.dcs.warwick.ac.uk/~fenghao/files/hidden_camera.pdf&quot;&gt;paper from the Warwick University (2023)&lt;/a&gt; researched LookCam app specifically. In additions to some vulnerabilities I mentioned here it contains a number of details on how these cameras operate.&lt;/p&gt;
  1488. &lt;p&gt;This &lt;a href=&quot;https://www.elastic.co/security-labs/storm-on-the-horizon&quot;&gt;Elastic Labs article (2024)&lt;/a&gt; took a close look at some other PPPP-based cameras, finding a number of issues.&lt;/p&gt;
  1489. &lt;p&gt;The &lt;a href=&quot;https://prezi.com/5cztk-98izyc/cs2-network-p2p/&quot;&gt;CS2 Network sales presentation (2016)&lt;/a&gt; offers a fascinating look into the thinking of PPPP protocol designers and into how their system was meant to work.&lt;/p&gt;</description>

  1497. &lt;p&gt;Welcome back to another edition of the Community Office Hours! This month, we’re taking a closer look at accessibility in the Thunderbird desktop and mobile apps. We’re chatting with Rebecca Taylor and Solange Valverde, members of our designer, about a recent accessibility (often shortened as a11y) study. We wanted to find out where Thunderbird was doing well, and where we could improve. Rebecca and Solange walk us through the study and answer our questions!&lt;/p&gt;

  1505. &lt;h3&gt;August Office Hours: Thunderbird Accessibility Study&lt;/h3&gt;
  1506.  
  1507.  
  1508.  
  1509. &lt;p&gt;The Thunderbird Team wants to make desktop and mobile apps that maximizes everyone’s productivity and freedom. This means making Thunderbird accessible for all of our users, and the first step is finding where we can do better. Thanks to our relationship with Mozilla, our design team commissioned a study with &lt;a href=&quot;https://makeitfable.com/&quot;&gt;Fable&lt;/a&gt;, who connects companies building inclusive products to experienced testers with disabilities. We asked participants to evaluate the Thunderbird desktop app using assistive tech, including screen readers, alternative navigation, and magnification. And we also asked a user on the cognitive spectrum to evaluate how our language, layouts, and reminders helped or hindered their use of the app.&lt;/p&gt;
  1510.  
  1511.  
  1512.  
  1513. &lt;p&gt;Members of the design team then conducted 60 minute moderated interviews with study participants. In these talks, participants pointed out where they struggled with accessibility roadblocks, and what strategies they used to try and work through them. &lt;/p&gt;
  1514.

  1521. &lt;p&gt;Screen readers convert on-screen text to either speech or Braille, and help blind or low-vision users navigate and access digital content. Our study participants, many of whom switch between multiple screen readers, let us know where Thunderbird falls short.&lt;/p&gt;

  1525. &lt;p&gt;Some issues were common to all screen readers. Keyboard shortcuts didn’t follow common norms, and workflows in search and filter results made for a confusing experience. Thunderbird could benefit from a table view with &lt;a href=&quot;https://www.a11yproject.com/posts/getting-started-aria/&quot;&gt;ARIA&lt;/a&gt;, a W3C specification created to improve accessibility. &lt;/p&gt;
  1526.  
  1527.  
  1528.  
  1529. &lt;p&gt;Other issues were specific to the individual screen reader programs. In Narrator, for example, expected confirmation for actions like moving messages was missing, and the screen reader didn’t recognize menu stage changes in submenus. In JAWS, meanwhile, message bodies were unreadable in email and compose windows with Braille display, and filter menus opened silently, not announcing the content or state to the user. Finally, with NVDA, users noted confusing structures and organization that lacked the structure and context they expected, as well as poor content prioritization.&lt;/p&gt;
  1530.  
  1531.  
  1532.  
  1533. &lt;h3&gt;Cognitive Usability&lt;/h3&gt;
  1534.  
  1535.  
  1536.  
  1537. &lt;p&gt;In a previous office hours, we talked about how we wanted to make Thunderbird more cognitively accessible with our work on the &lt;a href=&quot;https://blog.thunderbird.net/2024/01/january-2024-thunderbird-community-office-hours-how-to-join-us/&quot;&gt;Message Context Menu&lt;/a&gt;. Cognition relates to how we think, learn, understand, remember, and pay attention, and clear language, regular layouts, and meaningful reminders all improve cognitive accessibility. Our cognitive accessibility tester expressed concerns about a lack of a quick, non-technical setup, imbalances in our whitespace, and unpredictable layout controls, among other issues.&lt;/p&gt;
  1538.  
  1539.  
  1540.  
  1541. &lt;h3&gt;Alternative Navigation and Magnification&lt;/h3&gt;
  1542.  
  1543.  
  1544.  
  1545. &lt;p&gt;Our alternative navigation users tested how well they could use Thunderbird with voice controls and eye tracking software. Our voice control testers found room for improvement with menu action labels, better autofocus shift when scrolling through emails, and a larger font size for more comfortable voice-driven use. Likewise, our eye tracking software tester found issues with font sizes.  They also noted concerns with composition workflow and focus, too-small controls, and a drag-and-drop bug.&lt;/p&gt;
  1546.  
  1547.  
  1548.  
  1549. &lt;p&gt;Our magnification tester found where we could improve visual contrast and pane layouts. They also found off-screen elements could steal focus from new messages, and that folder paths and hierarchies could use more clarification. &lt;/p&gt;
  1550.  
  1551.  
  1552.  
  1553. &lt;h3&gt;Conclusions and Next Steps&lt;/h3&gt;
  1554.  
  1555.  
  1556.  
  1557. &lt;p&gt;We’re incredibly grateful for the insights we learned from this study on the many aspects of accessibility we want to improve in all of our apps. We want to thank Mozilla for their helping us take the next step in accessibility research, and Fable for providing a fantastic platform for accessibility testing. We’re also so grateful to our study participants for all their time and sharing their perspectives, concerns, and insights.&lt;/p&gt;
  1558.  
  1559.  
  1560.  
  1561. &lt;p&gt;This is far from the end of our accessibility journey. We’re looking forward to working what we learned in this study into deeper research and ultimately our desktop roadmap. We can’t wait to start accessibility research on our mobile apps. And we hope this study can help other open source projects start their own accessibility research to improve their projects.&lt;/p&gt;
  1562.  
  1563.  
  1564.  
  1565. &lt;p&gt;One way you can get involved is to report accessibility bugs on the desktop app. Go to the &lt;a href=&quot;https://bugzilla.mozilla.org/enter_bug.cgi?product=Thunderbird&quot;&gt;Thunderbird section on Bugzilla&lt;/a&gt;, and under ‘Component’ select ‘Disability Access.’ Additionally, click ‘Show Advanced Fields’ and enter ‘access’ into the ‘Details &amp;gt; Keywords’ section. Add screenshots when possible. Be sure to describe the bug so others can try and reproduce the it for better troubleshooting. &lt;/p&gt;
  1566.  
  1567.  
  1568.  
  1569. &lt;p&gt;If you want to learn more about our accessibility efforts, please join our User Experience mailing list! If you think you’re ready to get involved, please join our dedicated Matrix channel. We hope you help us make Thunderbird available, and accessible, everywhere!&lt;/p&gt;

  1623. <title>Mozilla Future Releases Blog: Firefox 32-bit Linux Support to End in 2026</title>
  1624. <guid isPermaLink="false">https://blog.mozilla.org/futurereleases/?p=2722</guid>
  1625. <link>https://blog.mozilla.org/futurereleases/2025/09/05/firefox-32-bit-linux-support-to-end-in-2026/</link>
  1626. <description>&lt;p&gt;For many years, Mozilla has continued to provide Firefox for 32-bit Linux systems long after most other browsers and operating systems ended support. We made this choice because we care deeply about keeping Firefox available to as many people as possible, helping our users extend the life of their hardware and reduce unnecessary obsolescence.&lt;/p&gt;
  1627. &lt;p&gt;Today, however, 32-bit Linux (on x86) is no longer widely supported by the vast majority of Linux distributions, and maintaining Firefox on this platform has become increasingly difficult and unreliable. To focus our efforts on delivering the best and most modern Firefox, we are &lt;b&gt;ending support for 32-bit x86 Linux&lt;/b&gt; with the release of Firefox 144 (or to rephrase, Firefox 145 will not have 32-bit Linux support).&lt;/p&gt;
  1628. &lt;p&gt;If you are currently using Firefox on a 32-bit x86 Linux system, we strongly encourage you to move to a 64-bit operating system and install the 64-bit version of Firefox, which will continue to be supported and updated.&lt;/p&gt;
  1629. &lt;p&gt;For users who cannot transition immediately, Firefox ESR 140 will remain available — including 32-bit builds — and will continue to receive security updates until at least &lt;b&gt;September 2026&lt;/b&gt;.&lt;/p&gt;
  1630. &lt;p&gt;[Updated on 2025-09-09 to clarify the affected builds are 32-bit x86]&lt;/p&gt;
  1631. &lt;p&gt;The post &lt;a href=&quot;https://blog.mozilla.org/futurereleases/2025/09/05/firefox-32-bit-linux-support-to-end-in-2026/&quot;&gt;Firefox 32-bit Linux Support to End in 2026&lt;/a&gt; appeared first on &lt;a href=&quot;https://blog.mozilla.org/futurereleases&quot;&gt;Future Releases&lt;/a&gt;.&lt;/p&gt;</description>

  1657. <title>Mozilla Future Releases Blog: Extended Firefox ESR 115 Support for Windows 7, 8, and 8.1 and macOS 10.12-10.14</title>
  1658. <guid isPermaLink="false">https://blog.mozilla.org/futurereleases/?p=2723</guid>

  1660. <description>&lt;p&gt;Mozilla has continued to support Firefox on Windows 7, Windows 8, and Windows 8.1 long after these operating systems reached end of life, helping users extend the life of their devices and reduce unnecessary obsolescence. We originally announced that security updates for &lt;a href=&quot;https://www.firefox.com/download/all/desktop-esr/&quot;&gt;Firefox ESR&lt;/a&gt; 115 would end in September 2024, later extending that into 2025.&lt;/p&gt;
  1661. &lt;p&gt;Today, we are extending support once again: &lt;b&gt;Firefox ESR 115 will continue to receive security updates on Windows 7, 8, and 8.1 until March 2026&lt;/b&gt;. This extension gives users more time to transition while ensuring critical security protections remain available. We still strongly encourage upgrading to a supported operating system to access the latest Firefox features and maintain long-term stability.&lt;/p&gt;
  1662. &lt;p&gt;Note that this extension is also applicable for macOS 10.12-10.14 users running Firefox ESR 115.&lt;/p&gt;

  1736. &lt;p&gt;An important step for RFC implementation is for people to experiment with the
  1737. implementation and give feedback, especially before stabilization.&lt;/p&gt;
  1738. &lt;p&gt;If you are a feature implementer and would like your RFC to appear in this list, add a
  1739. &lt;code&gt;call-for-testing&lt;/code&gt; label to your RFC along with a comment providing testing instructions and/or
  1740. guidance on which aspect(s) of the feature need testing.&lt;/p&gt;
  1741. &lt;ul&gt;
  1742. &lt;li&gt;&lt;em&gt;No calls for testing were issued this week by

  2135. &lt;p&gt;Bugs like this are the worst! It's almost impossible to catch them in development, because there is never enough load on the system to force the scheduler to move the execution to another thread. So, you end up with one of these &quot;impossible to reproduce, fails sometimes, but never for you&quot; bugs.&lt;/p&gt;
  2136. &lt;p&gt;It's mind-blowingly cool that the Rust compiler can detect something like this. And that seemingly unrelated parts of the language, like mutexes, lifetimes and async operations form such a coherent system.&lt;/p&gt;

  2148. <title>The Rust Programming Language Blog: Welcoming the Rust Innovation Lab</title>
  2149. <guid isPermaLink="true">https://blog.rust-lang.org/2025/09/03/welcoming-the-rust-innovation-lab/</guid>
  2150. <link>https://blog.rust-lang.org/2025/09/03/welcoming-the-rust-innovation-lab/</link>
  2151. <description>&lt;p&gt;TL;DR: &lt;a href=&quot;https://github.com/rustls/rustls&quot;&gt;Rustls&lt;/a&gt; is the inaugural project of the &lt;a href=&quot;https://rustfoundation.org/rust-innovation-lab&quot;&gt;Rust Innovation Lab&lt;/a&gt;, which is a new home for Rust projects under the Rust Foundation.&lt;/p&gt;
  2152. &lt;p&gt;At the Rust Foundation's August meeting, the Project Directors and the rest of the Rust Foundation board voted to approve &lt;a href=&quot;https://github.com/rustls/rustls&quot;&gt;Rustls&lt;/a&gt; as the first project housed under the newly formed Rust Innovation Lab. Prior to the vote, the Project Directors consulted with the Leadership Council who confirmed the Project's support for this initiative.&lt;/p&gt;
  2153. &lt;p&gt;The Rust Innovation Lab (RIL) is designed to provide support for funded Rust-based open source projects from the Rust Foundation in the form of governance, legal, networking, marketing, and administration, while keeping the technical direction solely in the hands of the current maintainers. As with the other work of the Rust Foundation (e.g. its many existing &lt;a href=&quot;https://rustfoundation.org/initiatives/&quot;&gt;initiatives&lt;/a&gt;), the purpose of the RIL is to strengthen the Rust ecosystem generally.&lt;/p&gt;
  2154. &lt;p&gt;The Foundation has been working behind the scenes to establish the Rust Innovation Lab, which includes setting up infrastructure under the Foundation to ensure smooth transition for Rustls into RIL. More details are available in &lt;a href=&quot;https://rustfoundation.org/media/rust-foundation-launches-rust-innovation-lab-with-rustls-as-inaugural-project/&quot;&gt;the Foundation's announcement&lt;/a&gt; and on &lt;a href=&quot;https://rustfoundation.org/rust-innovation-lab&quot;&gt;the Rust Innovation Lab's page&lt;/a&gt;.&lt;/p&gt;
  2155. &lt;p&gt;We are all excited by the formation of the Rust Innovation Lab. The support this initiative will provide to Rustls (and, eventually, other important projects that are using Rust) will improve software security for the entire industry. The Rust Project is grateful for the support of the Rust Foundation corporate members who are making this initiative possible for the benefit of everyone.&lt;/p&gt;
  2156. &lt;p&gt;More information on the criteria for projects wishing to become part of the RIL and the process for applying will be coming soon. The Project Directors and Leadership Council have been and will continue working with the Foundation to communicate information, questions, and feedback with the Rust community about the RIL as the details are worked out.&lt;/p&gt;</description>

  2161. <title>The Rust Programming Language Blog: Faster linking times with 1.90.0 stable on Linux using the LLD linker</title>
  2162. <guid isPermaLink="true">https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/</guid>
  2163. <link>https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/</link>
  2164. <description>&lt;p&gt;TL;DR: rustc will start using the LLD linker by default on the &lt;code&gt;x86_64-unknown-linux-gnu&lt;/code&gt; target starting with the next stable release (1.90.0, scheduled for 2025-09-18), which should significantly reduce linking times. Test it out on beta now, and please report any encountered issues.&lt;/p&gt;
  2165. &lt;h4 id=&quot;some-context&quot;&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/#some-context&quot;&gt;&lt;/a&gt;
  2166. Some context&lt;/h4&gt;
  2167. &lt;p&gt;Linking time is often a big part of compilation time. When rustc needs to build a binary or a shared library, it will usually call the default linker installed on the system to do that (this can be changed on the command-line or by the target for which the code is compiled).&lt;/p&gt;
  2168. &lt;p&gt;The linkers do an important job, with concerns about stability, backwards-compatibility and so on. For these and other reasons, on the most popular operating systems they usually are older programs, designed when computers only had a single core. So, they usually tend to be slow on a modern machine. For example, when building ripgrep 13 in debug mode on Linux, roughly half of the time is actually spent in the linker.&lt;/p&gt;
  2169. &lt;p&gt;There are different linkers, however, and the usual advice to improve linking times is to use one of these newer and faster linkers, like LLVM's &lt;a href=&quot;https://lld.llvm.org/&quot;&gt;&lt;code&gt;lld&lt;/code&gt;&lt;/a&gt; or Rui Ueyama's &lt;a href=&quot;https://github.com/rui314/mold&quot;&gt;&lt;code&gt;mold&lt;/code&gt;&lt;/a&gt;.&lt;/p&gt;
  2170. &lt;p&gt;Some of Rust's wasm and aarch64 targets already use &lt;code&gt;lld&lt;/code&gt; by default. When using rustup, rustc ships with a version of &lt;code&gt;lld&lt;/code&gt; for this purpose. When CI builds LLVM to use in the compiler, it also builds the linker and packages it. It's referred to as &lt;code&gt;rust-lld&lt;/code&gt; to avoid colliding with any &lt;code&gt;lld&lt;/code&gt; already installed on the user's machine.&lt;/p&gt;
  2171. &lt;p&gt;Since improvements to linking times are substantial, it would be a good default to use in the most popular targets. This has been discussed for a long time, for example in issues &lt;a href=&quot;https://github.com/rust-lang/rust/issues/39915&quot;&gt;#39915&lt;/a&gt; and &lt;a href=&quot;https://github.com/rust-lang/rust/issues/71515&quot;&gt;#71515&lt;/a&gt;.&lt;/p&gt;
  2172. &lt;p&gt;To expand our testing, we have enabled rustc to use &lt;code&gt;rust-lld&lt;/code&gt; by default on nightly, &lt;a href=&quot;https://blog.rust-lang.org/2024/05/17/enabling-rust-lld-on-linux.html&quot;&gt;in May 2024&lt;/a&gt;. No major issues have been reported since then.&lt;/p&gt;
  2173. &lt;p&gt;We believe we've done all the internal testing that we could, on CI, crater, on our benchmarking infrastructure and on nightly, and plan to enable &lt;code&gt;rust-lld&lt;/code&gt; to be the linker used by default on &lt;code&gt;x86_64-unknown-linux-gnu&lt;/code&gt; for stable builds in 1.90.0.&lt;/p&gt;
  2174. &lt;h4 id=&quot;benefits&quot;&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/#benefits&quot;&gt;&lt;/a&gt;
  2175. Benefits&lt;/h4&gt;
  2176. &lt;p&gt;While this also enables the compiler to use more linker features in the future, the most immediate benefit is much improved linking times.&lt;/p&gt;
  2177. &lt;p&gt;Here are more details from the ripgrep example mentioned above: for an incremental rebuild, linking is reduced 7x, resulting in a 40% reduction in end-to-end compilation times. For a from-scratch debug build, it is a 20% improvement.&lt;/p&gt;
  2178. &lt;p&gt;&lt;img alt=&quot;Before/after comparison of a ripgrep incremental debug build&quot; src=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/ripgrep-comparison.png&quot; /&gt;&lt;/p&gt;
  2179. &lt;p&gt;Most binaries should see some improvements here, but it's especially significant with e.g. bigger binaries, or for incremental rebuilds, or when involving debuginfo. These usually see bottlenecks in the linker.&lt;/p&gt;
  2180. &lt;p&gt;Here's &lt;a href=&quot;https://perf.rust-lang.org/compare.html?start=b3e117044c7f707293edc040edb93e7ec5f7040a&amp;amp;end=baed03c51a68376c1789cc373581eea0daf89967&amp;amp;stat=instructions%3Au&amp;amp;tab=compile&quot;&gt;a link&lt;/a&gt; to the complete results from our benchmarks.&lt;/p&gt;
  2181. &lt;h4 id=&quot;possible-drawbacks&quot;&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/#possible-drawbacks&quot;&gt;&lt;/a&gt;
  2182. Possible drawbacks&lt;/h4&gt;
  2183. &lt;p&gt;From our prior testing, we don't really expect issues to happen in practice. It is a drop-in replacement for the vast majority of cases, but &lt;code&gt;lld&lt;/code&gt; is not &lt;em&gt;bug-for-bug&lt;/em&gt; compatible with GNU ld.&lt;/p&gt;
  2184. &lt;p&gt;In any case, using &lt;code&gt;rust-lld&lt;/code&gt; can be disabled if any problem occurs: use the &lt;code&gt;-C linker-features=-lld&lt;/code&gt; flag to revert to using the system's default linker.&lt;/p&gt;
  2185. &lt;p&gt;Some crates somehow relying on these differences could need additional link args, though we also expect this to be quite rare. Let us know if you encounter problems, by &lt;a href=&quot;https://github.com/rust-lang/rust/issues/new/choose&quot;&gt;opening an issue&lt;/a&gt; on GitHub.&lt;/p&gt;
  2186. &lt;p&gt;Some of the big gains in performance come from parallelism, which could be undesirable in resource-constrained environments, or for heavy projects that are already reaching hardware limits.&lt;/p&gt;
  2187. &lt;h4 id=&quot;summary-and-call-for-testing&quot;&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/#summary-and-call-for-testing&quot;&gt;&lt;/a&gt;
  2188. Summary, and call for testing&lt;/h4&gt;
  2189. &lt;p&gt;rustc will use &lt;code&gt;rust-lld&lt;/code&gt; on &lt;code&gt;x86_64-unknown-linux-gnu&lt;/code&gt;, starting with the 1.90.0 stable release, for much improved linking times. Rust 1.90.0 will be released next month, on the 18th of September 2025.&lt;/p&gt;
  2190. &lt;p&gt;This linker change is already available on the current beta (&lt;code&gt;1.90.0-beta.6&lt;/code&gt;). To help everyone prepare for this landing on stable, please test your projects on beta and let us know if you encounter problems, by &lt;a href=&quot;https://github.com/rust-lang/rust/issues/new/choose&quot;&gt;opening an issue&lt;/a&gt; on GitHub.&lt;/p&gt;
  2191. &lt;p&gt;If that happens, you can revert to the default linker with the &lt;code&gt;-C linker-features=-lld&lt;/code&gt; flag. Either by adding it to the usual &lt;code&gt;RUSTFLAGS&lt;/code&gt; environment variable, or to a project's &lt;a href=&quot;https://doc.rust-lang.org/cargo/reference/config.html&quot;&gt;&lt;code&gt;.cargo/config.toml&lt;/code&gt;&lt;/a&gt; configuration file,
  2192. like so:&lt;/p&gt;
  2193. &lt;pre class=&quot;language-toml z-code&quot;&gt;&lt;code class=&quot;language-toml&quot;&gt;&lt;span class=&quot;z-source z-toml&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-table z-begin z-toml&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;z-meta z-tag z-table z-toml&quot;&gt;&lt;span class=&quot;z-entity z-name z-table z-toml&quot;&gt;target&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-table z-toml&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;z-entity z-name z-table z-toml&quot;&gt;x86_64-unknown-linux-gnu&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-definition z-table z-end z-toml&quot;&gt;]&lt;/span&gt;
  2194. &lt;/span&gt;&lt;span class=&quot;z-source z-toml&quot;&gt;&lt;span class=&quot;z-meta z-tag z-key z-toml&quot;&gt;&lt;span class=&quot;z-entity z-name z-tag z-toml&quot;&gt;rustflags&lt;/span&gt;&lt;/span&gt; &lt;span class=&quot;z-punctuation z-definition z-key-value z-toml&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;z-punctuation z-definition z-array z-begin z-toml&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;z-string z-quoted z-double z-basic z-toml&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-string z-begin z-toml&quot;&gt;&quot;&lt;/span&gt;-Clinker-features=-lld&lt;span class=&quot;z-punctuation z-definition z-string z-end z-toml&quot;&gt;&quot;&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-definition z-array z-end z-toml&quot;&gt;]&lt;/span&gt;

  2200. <title>The Mozilla Blog: Speeding up Firefox Local AI Runtime</title>
  2201. <guid isPermaLink="false">https://blog.mozilla.org/?p=81570</guid>
  2202. <link>https://blog.mozilla.org/en/firefox/firefox-ai/speeding-up-firefox-local-ai-runtime/</link>
  2203. <description>&lt;p&gt;Last year we rolled out the &lt;strong&gt;&lt;a href=&quot;https://firefox-source-docs.mozilla.org/toolkit/components/ml/&quot;&gt;Firefox AI Runtime&lt;/a&gt;&lt;/strong&gt;, the engine that quietly powers features such as &lt;a href=&quot;https://hacks.mozilla.org/2024/05/experimenting-with-local-alt-text-generation-in-firefox-nightly/&quot;&gt;PDF.js generated alt text&lt;/a&gt; and, more recently, &lt;a href=&quot;https://support.mozilla.org/en-US/kb/how-use-ai-enhanced-tab-groups&quot;&gt;our &lt;em&gt;smart tab grouping&lt;/em&gt;&lt;/a&gt;. The system worked, but not quite at the speed we wanted.&lt;/p&gt;
  2204.  
  2205.  
  2206.  
  2207. &lt;p&gt;This post explains how we accelerated inference by replacing the default &lt;strong&gt;&lt;a href=&quot;https://github.com/microsoft/onnxruntime&quot;&gt;onnxruntime‑web&lt;/a&gt;&lt;/strong&gt; that powers &lt;a href=&quot;https://huggingface.co/docs/transformers.js/en/index&quot;&gt;Transformers.js&lt;/a&gt; with its native C++ counterpart that now lives inside Firefox.&lt;/p&gt;
  2208.  
  2209.  
  2210.  
  2211. &lt;h4&gt;Where we started&lt;/h4&gt;
  2212.  
  2213.  
  2214.  
  2215. &lt;p&gt;Transformers.js is the JavaScript counterpart to Hugging Face’s Python library. Under the hood it relies on &lt;strong&gt;onnxruntime‑web&lt;/strong&gt;, a WebAssembly (WASM) build of ONNX Runtime.&lt;/p&gt;
  2216.  
  2217.  
  2218.  
  2219. &lt;p&gt;A typical inference cycle:&lt;/p&gt;
  2220.  
  2221.  
  2222.  
  2223. &lt;ol&gt;
  2224. &lt;li&gt;&lt;strong&gt;Pre‑processing&lt;/strong&gt; in JavaScript (tokenization, tensor shaping)&lt;/li&gt;
  2225.  
  2226.  
  2227.  
  2228. &lt;li&gt;&lt;strong&gt;Model execution&lt;/strong&gt; in WASM&lt;/li&gt;
  2229.  
  2230.  
  2231.  
  2232. &lt;li&gt;&lt;strong&gt;Post‑processing&lt;/strong&gt; back in JavaScript&lt;/li&gt;
  2233. &lt;/ol&gt;
  2234.  
  2235.  
  2236.  
  2237. &lt;p&gt;Even with warm caches, that dance crosses multiple layers. The real hotspot is the matrix multiplications, implemented with generic SIMD when running on CPU.&lt;/p&gt;
  2238.  
  2239.  
  2240.  
  2241. &lt;h4&gt;Why plain WASM wasn’t enough&lt;/h4&gt;
  2242.  
  2243.  
  2244.  
  2245. &lt;p&gt;WASM SIMD is great, but it can’t beat hardware‑specific instructions such as NEON on Apple Silicon or AVX‑512 on modern Intel chips.&lt;/p&gt;
  2246.  
  2247.  
  2248.  
  2249. &lt;p&gt;&lt;a href=&quot;https://www.firefox.com/en-US/features/translate/&quot;&gt;Firefox Translations&lt;/a&gt; (uses &lt;em&gt;Bergamot&lt;/em&gt;) already proves that diving to native code speeds things up: it uses &lt;strong&gt;WASM built‑ins&lt;/strong&gt; which are small hooks that let WASM call into C++ compiled with those intrinsics. The project, nicknamed &lt;em&gt;&lt;a href=&quot;https://github.com/mozilla/gemmology&quot;&gt;gemmology&lt;/a&gt;&lt;/em&gt;, works brilliantly.&lt;/p&gt;
  2250.  
  2251.  
  2252.  
  2253. &lt;p&gt;We tried porting that trick to ONNX, but the huge number of operators made a one‑by‑one rewrite unmaintainable. And each cold start still paid the JS/WASM warm‑up tax.&lt;/p&gt;
  2254.  
  2255.  
  2256.  
  2257. &lt;h4&gt;Switching to ONNX C++&lt;/h4&gt;
  2258.  
  2259.  
  2260.  
  2261. &lt;p&gt;Transformers.js talks to ONNX Runtime through a &lt;em&gt;tiny&lt;/em&gt; surface. It creates a session, pushes a Tensor, and pulls a result. It makes it simple to swap the backend without touching feature code.&lt;/p&gt;
  2262.  
  2263.  
  2264.  
  2265. &lt;p&gt;Our steps to achieve this were:&lt;/p&gt;
  2266.  
  2267.  
  2268.  
  2269. &lt;ol&gt;
  2270. &lt;li&gt;&lt;strong&gt;Vendor ONNX Runtime C++&lt;/strong&gt; directly into the Firefox tree.&lt;/li&gt;
  2271.  
  2272.  
  2273.  
  2274. &lt;li&gt;&lt;strong&gt;Expose&lt;/strong&gt; it to JavaScript via a thin WebIDL layer.&lt;/li&gt;
  2275.  
  2276.  
  2277.  
  2278. &lt;li&gt;&lt;strong&gt;Wire&lt;/strong&gt; Transformers.js to the new backend.&lt;/li&gt;
  2279. &lt;/ol&gt;
  2280.  
  2281.  
  2282.  
  2283. &lt;p&gt;From the perspective of a feature like PDF alt‑text, nothing changed, it still calls await pipeline(…). Underneath, tensors now go straight to native code.&lt;/p&gt;
  2284.  
  2285.  
  2286.  
  2287. &lt;h4&gt;Integration of ONNX Runtime to the build system&lt;/h4&gt;
  2288.  
  2289.  
  2290.  
  2291. &lt;p&gt;Upstream ONNX runtime does not support all of our build configuration, and it’s a large amount of code. As a consequence we chose not to add it in-tree. Instead, a configuration flag can be used to provide a compiled version of the ONNX runtime. It is eventually automatically downloaded from &lt;a href=&quot;https://taskcluster.net/&quot;&gt;Taskcluster&lt;/a&gt; (where we build it for a selection of supported configuration) or provided by downstream developers. This provides flexibility while not slowing down our usual build and requiring low maintenance.&lt;/p&gt;
  2292.  
  2293.  
  2294.  
  2295. &lt;p&gt;Building ONNX on Taskcluster required some configuration changes and upstream patches. The goal was to find a balance between speed and binary size, while being compatible with native code requirements from the Firefox repo. &lt;/p&gt;
  2296.  
  2297.  
  2298.  
  2299. &lt;p&gt;Most notably:&lt;/p&gt;
  2300.  
  2301.  
  2302.  
  2303. &lt;ul&gt;
  2304. &lt;li&gt;Building without exception and RTTI support required some patches upstream&lt;/li&gt;
  2305.  
  2306.  
  2307.  
  2308. &lt;li&gt;Default build configuration is set to MinSizeRel, compilation uses LTO&lt;/li&gt;
  2309. &lt;/ul&gt;
  2310.  
  2311.  
  2312.  
  2313. &lt;h4&gt;The payoff&lt;/h4&gt;
  2314.  
  2315.  
  2316.  
  2317. &lt;p&gt;Because the native backend is a drop‑in replacement, we can enable it feature by feature and gather real‑world numbers. Early benchmarks shows from &lt;strong&gt;2 to 10 × faster&lt;/strong&gt; inference, with zero WASM warm‑up overhead.&lt;/p&gt;
  2318.  
  2319.  
  2320.  
  2321. &lt;p&gt;For example, the Smart Tab Grouping topic suggestion, which can be laggy on first run, is now quite snappy, and this is the first feature we gradually moved to this backend for Firefox 142.&lt;/p&gt;
  2322.  
  2323.  
  2324.  
  2325. &lt;figure class=&quot;wp-block-image&quot;&gt;&lt;img alt=&quot;graph showing the difference between WASM and c++ backend. the C++ being way faster&quot; class=&quot;wp-image-81582&quot; height=&quot;658&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/08/image.png&quot; width=&quot;1018&quot; /&gt;&lt;/figure&gt;
  2326.  
  2327.  
  2328.  
  2329. &lt;p&gt;The image to text model used for PDF.js alt-text feature also benefited from this change. On the same hardware the latency went from from 3.5s to 350ms.&lt;/p&gt;
  2330.  
  2331.  
  2332.  
  2333. &lt;h4&gt;What’s next&lt;/h4&gt;
  2334.  
  2335.  
  2336.  
  2337. &lt;p&gt;We’re gradually rolling out this new backend to additional features throughout the summer, so all capabilities built on Transformers.js can take advantage of it. &lt;/p&gt;
  2338.  
  2339.  
  2340.  
  2341. &lt;p&gt;And with the C++ API at hand, we’re planning to tackle a few long‑standing pain points, and enable GPU.&lt;/p&gt;
  2342.  
  2343.  
  2344.  
  2345. &lt;p&gt;Those changes will ship in our vendored ONNX Runtime and offer us the best possible performance for Transformers.js-based features in our runtime in the future.&lt;/p&gt;
  2346.  
  2347.  
  2348.  
  2349. &lt;h5&gt;1. DequantizeLinear goes multi‑threaded&lt;/h5&gt;
  2350.  
  2351.  
  2352.  
  2353. &lt;p&gt;The DequantizeLinear operation is single‑threaded and often dominated inference time. While upstream work recently merged an improvement (&lt;a href=&quot;https://github.com/microsoft/onnxruntime/pull/24818&quot;&gt;PR #24818&lt;/a&gt;), we built a patch to spread the work across cores, letting the compiler auto‑vectorize the inner loops. The result is an almost linear speedup, especially on machines with many cores.&lt;/p&gt;
  2354.  
  2355.  
  2356.  
  2357. &lt;h5&gt;2. Matrix transposition goes multi-threaded&lt;/h5&gt;
  2358.  
  2359.  
  2360.  
  2361. &lt;p&gt;Similarly, it is typical to have to transpose very large (multiple dozen megabytes) matrices when performing an inference task. This operation was done naively with nested for loops. Switching to a multi-threaded cache-aware tiled transposition scheme, and leveraging SIMD allowed to take advantage of modern hardware and speed up this operation by a supra-linear factor, typically twice the number of threads allocated to this task, for example a 8x speedup using 4 threads.&lt;/p&gt;
  2362.  
  2363.  
  2364.  
  2365. &lt;p&gt;This can be explained by the fact that the naive for loop was auto-vectorized, but otherwise did poor usage of CPU caches.&lt;/p&gt;
  2366.  
  2367.  
  2368.  
  2369. &lt;h5&gt;3. Caching the compiled graph&lt;/h5&gt;
  2370.  
  2371.  
  2372.  
  2373. &lt;p&gt;Before an inference can run, ONNX Runtime compiles the model graph for the current platform. On large models such as &lt;em&gt;Qwen 2.5 0.5B&lt;/em&gt; this can cost up to five seconds every launch. &lt;/p&gt;
  2374.  
  2375.  
  2376.  
  2377. &lt;p&gt;We can cache the compiled graph separately from the weights on the fly, shaving anywhere from a few milliseconds to the full five seconds.&lt;/p&gt;
  2378.  
  2379.  
  2380.  
  2381. &lt;h5&gt;4. Using GPUs&lt;/h5&gt;
  2382.  
  2383.  
  2384.  
  2385. &lt;p&gt;Currently, we’ve integrated only CPU-based providers. The next step is to support GPU-accelerated ONNX backends, which will require more effort. This is because GPU support demands additional sandboxing to safely and securely interact with the underlying hardware.&lt;/p&gt;
  2386.  
  2387.  
  2388.  
  2389. &lt;h3&gt;Conclusion&lt;/h3&gt;
  2390.  
  2391.  
  2392.  
  2393. &lt;p&gt;What is interesting about this migration is the fact that we could improve performance that much, while migrating features gradually, and all that in complete isolation, without having to change any feature code.&lt;/p&gt;
  2394.  
  2395.  
  2396.  
  2397. &lt;p&gt;While the speed ups are already visible from a UX standpoint, we believe that a lot of improvement can and will happen in the future, further improving the efficiency of the ML-based features, and making them more accessible to a wider audience.&lt;/p&gt;
  2398.

  2415. &lt;p&gt;We’re back with another exciting Monthly Release recap! Thunderbird 142.0 brings a host of user-requested features and important bug fixes that make your email experience smoother and more reliable. From better folder management to smarter PDF handling, this release focuses on the details that matter most to your daily workflow.&lt;/p&gt;
  2416.  
  2417.  
  2418.  
  2419. &lt;p&gt;&lt;strong&gt;A quick reminder&lt;/strong&gt; – these updates are for users on our &lt;strong&gt;monthly Thunderbird Release channel&lt;/strong&gt;. For our users still on the ESR (Extended Standard Release) channel, these updates won’t land until next July 2026. For more information on the differences between the channels and how to make the switch:&lt;/p&gt;

  2429. &lt;/ul&gt;
  2430.  
  2431.  
  2432.  
  2433. &lt;p&gt;Now let’s dive into &lt;strong&gt;what’s new in 142.0!&lt;/strong&gt;&lt;/p&gt;
  2434.  
  2435.  
  2436.  
  2437. &lt;h3&gt;&lt;strong&gt;New Features:&lt;/strong&gt;&lt;/h3&gt;
  2438.  
  2439.  
  2440.  
  2441. &lt;h4&gt;&lt;strong&gt;Reset Manual Folder Sorting&lt;/strong&gt; &lt;/h4&gt;
  2442.  
  2443.  
  2444.  
  2445. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972710&quot;&gt;Bug 1972710&lt;/a&gt;&lt;/p&gt;
  2446.  
  2447.  
  2448.  
  2449. &lt;p&gt;Ever tweaked your folder order and wished you could start fresh? We hear you! Thunderbird 142 introduces a simple way to reset your folder sorting back to defaults. &lt;/p&gt;
  2450.  
  2451.  
  2452.  
  2453. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2454.  
  2455.  
  2456.  
  2457. &lt;ul&gt;
  2458. &lt;li&gt;The new Reset Folder Order option lets users right‑click an account in the Folder Pane to instantly clear any custom sorting. &lt;/li&gt;
  2459.  
  2460.  
  2461.  
  2462. &lt;li&gt;Provides a quick clean slate and avoids manually dragging folders back to default positions.&lt;/li&gt;
  2463. &lt;/ul&gt;
  2464.  
  2465.  
  2466.  
  2467. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/08/reset-folder-sort.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3751&quot; height=&quot;555&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/reset-folder-sort.png&quot; width=&quot;416&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  2468.  
  2469.  
  2470.  
  2471. &lt;p&gt;&lt;em&gt;Note: This feature resets sorting order but doesn’t restore folders that were moved inside different parent folders.&lt;/em&gt;&lt;/p&gt;
  2472.  
  2473.  
  2474.  
  2475. &lt;div class=&quot;wp-block-spacer&quot; style=&quot;height: 25px;&quot;&gt;&lt;/div&gt;
  2476.  
  2477.  
  2478.  
  2479. &lt;h4&gt;&lt;strong&gt;PDF Signatures and Attachment Handling&lt;/strong&gt;&lt;/h4&gt;
  2480.  
  2481.  
  2482.  
  2483. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970796&quot;&gt;Bug 1970796&lt;/a&gt;&lt;/p&gt;
  2484.  
  2485.  
  2486.  
  2487. &lt;p&gt;Thunderbird now lets you &lt;strong&gt;add visual signatures to PDF attachments&lt;/strong&gt; opened inside the app. This update brings Thunderbird in line with modern PDF functionality, making it easier to handle contracts, forms, and other documents without leaving your inbox.&lt;/p&gt;
  2488.  
  2489.  
  2490.  
  2491. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2492.  
  2493.  
  2494.  
  2495. &lt;ul&gt;
  2496. &lt;li&gt;Add a handwritten-style visual signature directly in Thunderbird.&lt;/li&gt;
  2497.  
  2498.  
  2499.  
  2500. &lt;li&gt;No need for external tools to sign simple PDF documents.&lt;/li&gt;
  2501.  
  2502.  
  2503.  
  2504. &lt;li&gt;Keeps everyday document handling faster and more convenient.&lt;/li&gt;
  2505. &lt;/ul&gt;
  2506.  
  2507.  
  2508.  
  2509. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/08/PDF-Signature.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3758&quot; height=&quot;345&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/PDF-Signature.png&quot; width=&quot;1867&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;

  2516.  
  2517.  
  2518.  
  2519. &lt;h4&gt;&lt;strong&gt;Custom OAuth Support for Add-on developers&lt;/strong&gt;&lt;/h4&gt;
  2520.  
  2521.  
  2522.  
  2523. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1967370&quot;&gt;Bug 1967370&lt;/a&gt;&lt;/p&gt;
  2524.  
  2525.  
  2526.  
  2527. &lt;p&gt;New add-on API support for OAuth client registration now allows developers and organizations to add custom OAuth providers at runtime. Instead of requiring changes in Thunderbird’s core code, an add-on can handle the setup. &lt;/p&gt;
  2528.  
  2529.  
  2530.  
  2531. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2532.  
  2533.  
  2534.  
  2535. &lt;ul&gt;
  2536. &lt;li&gt;Supports custom OAuth providers through add-ons.&lt;/li&gt;
  2537.  
  2538.  
  2539.  
  2540. &lt;li&gt;Works with enterprise policies for organizational deployments.&lt;/li&gt;
  2541.  
  2542.  
  2543.  
  2544. &lt;li&gt;Simplifies integration with unique authentication systems.&lt;/li&gt;
  2545. &lt;/ul&gt;
  2546.  
  2547.  
  2548.  
  2549. &lt;ul&gt;
  2550. &lt;div class=&quot;wp-block-spacer&quot; style=&quot;height: 30px;&quot;&gt;&lt;/div&gt;
  2551. &lt;/ul&gt;
  2552.  
  2553.  
  2554.  
  2555. &lt;h3&gt;&lt;strong&gt;Bug Fixes&lt;/strong&gt;&lt;/h3&gt;
  2556.  
  2557.  
  2558.  
  2559. &lt;h4&gt;&lt;strong&gt;Respect for “Do Not Disturb”&lt;/strong&gt;&lt;/h4&gt;
  2560.  
  2561.  
  2562.  
  2563. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1876310&quot;&gt;Bug 1876310&lt;/a&gt;&lt;/p&gt;
  2564.  
  2565.  
  2566.  
  2567. &lt;p&gt;Your focus time is sacred, and Thunderbird now honors that across all operating systems.&lt;/p&gt;
  2568.  
  2569.  
  2570.  
  2571. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2572.  
  2573.  
  2574.  
  2575. &lt;ul&gt;
  2576. &lt;li&gt;Native OS notifications now respect the “Do Not Disturb” setting of every operating system, including blocking calendar reminders and chat notification sounds.&lt;/li&gt;
  2577.  
  2578.  
  2579.  
  2580. &lt;li&gt;Delivers protected focus time and consistent behavior with other applications.&lt;/li&gt;
  2581. &lt;/ul&gt;
  2582.  
  2583.  
  2584.  
  2585. &lt;ul&gt;
  2586. &lt;div class=&quot;wp-block-spacer&quot; style=&quot;height: 25px;&quot;&gt;&lt;/div&gt;
  2587. &lt;/ul&gt;
  2588.  
  2589.  
  2590.  
  2591. &lt;h4&gt;&lt;strong&gt;Improved Dark Reader Mode Toggle&lt;/strong&gt;&lt;/h4&gt;
  2592.  
  2593.  
  2594.  
  2595. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1962931&quot;&gt;Bug 1962931&lt;/a&gt;&lt;/p&gt;
  2596.  
  2597.  
  2598.  
  2599. &lt;p&gt;Reading flow is now smoother when switching between &lt;strong&gt;light and dark message modes&lt;/strong&gt;.  An issue was reported where toggling the setting in the message header would reset your scroll position and pull focus away from the message body. &lt;/p&gt;
  2600.  
  2601.  
  2602.  
  2603. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2604.  
  2605.  
  2606.  
  2607. &lt;ul&gt;
  2608. &lt;li&gt;Keep your scroll position in the message when switching between light and dark mode so you can continue reading without interruption.&lt;/li&gt;
  2609.  
  2610.  
  2611.  
  2612. &lt;li&gt;Retain focus on the message body for easier keyboard navigation.&lt;/li&gt;
  2613.  
  2614.  
  2615.  
  2616. &lt;li&gt;Reduce extra clicks and scrolling, making reading more seamless.&lt;/li&gt;
  2617. &lt;/ul&gt;
  2618.  
  2619.  
  2620.  
  2621. &lt;ul&gt;
  2622. &lt;div class=&quot;wp-block-spacer&quot; style=&quot;height: 25px;&quot;&gt;&lt;/div&gt;
  2623. &lt;/ul&gt;
  2624.  
  2625.  
  2626.  
  2627. &lt;h4&gt;&lt;strong&gt;Message List Scrolling Fix&lt;/strong&gt;&lt;/h4&gt;
  2628.  
  2629.  
  2630.  
  2631. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1968967&quot;&gt;Bug 1968967&lt;/a&gt;&lt;/p&gt;
  2632.  
  2633.  
  2634.  
  2635. &lt;p&gt;&lt;strong&gt;Unwanted scrolling of the message list&lt;/strong&gt; that happened when returning to the Mail tab after opening a message is now a thing of the past. Instead of jumping to the top and slowly scrolling back down, the list now stays put.&lt;/p&gt;
  2636.  
  2637.  
  2638.  
  2639. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2640.  
  2641.  
  2642.  
  2643. &lt;ul&gt;
  2644. &lt;li&gt;Keep your place in the message list when switching tabs.&lt;/li&gt;
  2645. &lt;/ul&gt;
  2646.  
  2647.  
  2648.  
  2649. &lt;ul&gt;
  2650. &lt;div class=&quot;wp-block-spacer&quot; style=&quot;height: 25px;&quot;&gt;&lt;/div&gt;
  2651. &lt;/ul&gt;
  2652.  
  2653.  
  2654.  
  2655. &lt;h4&gt;&lt;strong&gt;PDF Attachments Reload Correctly on Startup&lt;/strong&gt;&lt;/h4&gt;
  2656.  
  2657.  
  2658.  
  2659. &lt;p class=&quot;has-small-font-size&quot;&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970615&quot;&gt;Bug 1970615&lt;/a&gt;&lt;/p&gt;
  2660.  
  2661.  
  2662.  
  2663. &lt;p&gt;Thunderbird now correctly &lt;strong&gt;reloads PDF attachments&lt;/strong&gt; that were left open in tabs when you restart the app. Previously, these tabs would fail to open and display an error, forcing you to reload them manually.&lt;/p&gt;
  2664.  
  2665.  
  2666.  
  2667. &lt;p&gt;&lt;strong&gt;Benefits:&lt;/strong&gt;&lt;/p&gt;
  2668.  
  2669.  
  2670.  
  2671. &lt;ul&gt;
  2672. &lt;li&gt;Open PDF attachments are restored automatically on startup.&lt;/li&gt;
  2673.  
  2674.  
  2675.  
  2676. &lt;li&gt;No more error messages when resuming work.&lt;/li&gt;
  2677. &lt;/ul&gt;

  2734. &lt;p&gt;An important step for RFC implementation is for people to experiment with the
  2735. implementation and give feedback, especially before stabilization.&lt;/p&gt;
  2736. &lt;p&gt;If you are a feature implementer and would like your RFC to appear in this list, add a
  2737. &lt;code&gt;call-for-testing&lt;/code&gt; label to your RFC along with a comment providing testing instructions and/or
  2738. guidance on which aspect(s) of the feature need testing.&lt;/p&gt;
  2739. &lt;ul&gt;
  2740. &lt;li&gt;&lt;em&gt;No calls for testing were issued this week by

  3197. &lt;p&gt;I &lt;code&gt;clone()&lt;/code&gt; everything now. The Borrow Checker permits this small rebellion, this inefficiency. It knows I suffer more knowing my code is not idiomatic. Every &lt;code&gt;.clone()&lt;/code&gt; is a confession of my failure. Every &lt;code&gt;Arc&amp;lt;Mutex&amp;lt;T&amp;gt;&amp;gt;&lt;/code&gt; a monument to my inadequacy.&lt;/p&gt;

  3211. <link>https://servo.org/blog/2025/08/22/this-month-in-servo/</link>
  3212. <description>&lt;p&gt;Servo has smashed its record again in July, with &lt;strong&gt;367 pull requests&lt;/strong&gt; landing in our nightly builds!
  3213. This includes several new web platform features:&lt;/p&gt;
  3214. &lt;ul&gt;
  3215. &lt;li&gt;&lt;strong&gt;APNG&lt;/strong&gt; and &lt;strong&gt;WebP animated images&lt;/strong&gt;, in addition to GIF (&lt;a href=&quot;https://github.com/rayguo17&quot;&gt;@rayguo17&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37637&quot;&gt;#37637&lt;/a&gt;)&lt;/li&gt;
  3216. &lt;li&gt;&lt;strong&gt;&amp;lt;source width&amp;gt;&lt;/strong&gt; and &lt;strong&gt;&amp;lt;source height&amp;gt;&lt;/strong&gt; (&lt;a href=&quot;https://github.com/leo030303&quot;&gt;@leo030303&lt;/a&gt;, &lt;a href=&quot;https://github.com/xiaochengh&quot;&gt;@xiaochengh&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38152&quot;&gt;#38152&lt;/a&gt;)&lt;/li&gt;
  3217. &lt;li&gt;&lt;strong&gt;TextDecoderStream&lt;/strong&gt; (&lt;a href=&quot;https://github.com/minghuaw&quot;&gt;@minghuaw&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38112&quot;&gt;#38112&lt;/a&gt;)&lt;/li&gt;
  3218. &lt;li&gt;&lt;strong&gt;replace() method&lt;/strong&gt; on &lt;strong&gt;CSSStyleSheet&lt;/strong&gt; (&lt;a href=&quot;https://github.com/stevennovaryo&quot;&gt;@stevennovaryo&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38244&quot;&gt;#38244&lt;/a&gt;)&lt;/li&gt;
  3219. &lt;li&gt;&lt;strong&gt;texImage3D() method&lt;/strong&gt; on &lt;strong&gt;WebGL2RenderingContext&lt;/strong&gt; (&lt;a href=&quot;https://github.com/wusyong&quot;&gt;@wusyong&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37718&quot;&gt;#37718&lt;/a&gt;)&lt;/li&gt;
  3220. &lt;li&gt;&lt;strong&gt;convertToBlob()&lt;/strong&gt; and &lt;strong&gt;transferToImageBitmap() methods&lt;/strong&gt; on &lt;strong&gt;OffscreenCanvas&lt;/strong&gt; (&lt;a href=&quot;https://github.com/tharkum&quot;&gt;@tharkum&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37786&quot;&gt;#37786&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37880&quot;&gt;#37880&lt;/a&gt;)&lt;/li&gt;
  3221. &lt;li&gt;&lt;strong&gt;adoptedStyleSheets property&lt;/strong&gt; on &lt;strong&gt;Document&lt;/strong&gt; and &lt;strong&gt;ShadowRoot&lt;/strong&gt;, with &lt;code&gt;--pref dom_adoptedstylesheet_enabled&lt;/code&gt; (&lt;a href=&quot;https://github.com/stevennovaryo&quot;&gt;@stevennovaryo&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38163&quot;&gt;#38163&lt;/a&gt;)&lt;/li&gt;
  3222. &lt;li&gt;&lt;strong&gt;ImageBitmap&lt;/strong&gt; no longer requires &lt;code&gt;--enable-experimental-web-platform-features&lt;/code&gt; (&lt;a href=&quot;https://github.com/tharkum&quot;&gt;@tharkum&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38050&quot;&gt;#38050&lt;/a&gt;)&lt;/li&gt;
  3223. &lt;/ul&gt;
  3224. &lt;p&gt;Notable changes for Servo library consumers:&lt;/p&gt;
  3225. &lt;ul&gt;
  3226. &lt;li&gt;
  3227. &lt;p&gt;&lt;strong&gt;Stylo 0.6.0&lt;/strong&gt; was released, &lt;strong&gt;fixing build errors&lt;/strong&gt; caused by an undeclared dependency on &lt;code&gt;markupsafe&lt;/code&gt; (&lt;a href=&quot;https://github.com/nicoburns&quot;&gt;@nicoburns&lt;/a&gt;, &lt;a href=&quot;https://github.com/delan&quot;&gt;@delan&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/stylo/pull/215&quot;&gt;stylo#215&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/stylo/issues/218&quot;&gt;stylo#218&lt;/a&gt;).
  3228. To work around this in Stylo 0.5.0, install the dependency: &lt;code&gt;pip install markupsafe&lt;/code&gt;&lt;/p&gt;
  3229. &lt;/li&gt;
  3230. &lt;li&gt;
  3231. &lt;p&gt;&lt;a href=&quot;https://doc.servo.org/servo/struct.WebView.html#method.notify_scroll_event&quot;&gt;&lt;strong&gt;notify_scroll_event()&lt;/strong&gt; on WebView&lt;/a&gt; now &lt;strong&gt;scrolls down as the &lt;code&gt;y&lt;/code&gt; value increases&lt;/strong&gt; (&lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37752&quot;&gt;#37752&lt;/a&gt;), consistent with the web platform.
  3232. This is a &lt;strong&gt;breaking change to the Servo API&lt;/strong&gt;.&lt;/p&gt;
  3233. &lt;/li&gt;
  3234. &lt;/ul&gt;
  3235. &lt;figure&gt;
  3236.  &lt;details&gt;
  3237.    &lt;img alt=&quot;servoshell nightly showing the same things, but animated&quot; src=&quot;https://servo.org/img/blog/2025-08-diffies.webp&quot; style=&quot;margin: 0;&quot; /&gt;
  3238.    &lt;img src=&quot;https://servo.org/img/blog/2025-08-diffies.jpg&quot; style=&quot;margin: 0;&quot; /&gt;&lt;div alt=&quot;servoshell nightly showing APNG and WebP animated images, ‘image-rendering’ applying to a ‘border-image’, a WebGL 2 example using texImage3D(), ‘text-decoration’ applying to a link with spaces, and an example of adoptedStyleSheets being controlled by a color input&quot;&gt;▶&lt;/div&gt;
  3239.  &lt;/details&gt;
  3240.  &amp;lt;figcaption&amp;gt;texImage3D() example reproduced from &lt;a href=&quot;https://webglsamples.org/WebGL2Samples/#texture_2d_array&quot;&gt;texture_2d_array&lt;/a&gt; in the &lt;a href=&quot;https://github.com/WebGLSamples/WebGL2Samples&quot;&gt;&lt;i&gt;WebGL 2.0 Samples&lt;/i&gt;&lt;/a&gt; by Trung Le, Shuai Shao (Shrek), et al (&lt;a href=&quot;https://github.com/WebGLSamples/WebGL2Samples/blob/7aef7dd1ef2615e657e0110df10a0fd6270cd50e/LICENSE.md&quot;&gt;license&lt;/a&gt;).&amp;lt;/figcaption&amp;gt;
  3241. &lt;/figure&gt;
  3242. &lt;h3&gt;Engine changes &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/08/22/this-month-in-servo/#engine-changes&quot;&gt;
  3243.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  3244.      &lt;/a&gt;&lt;/h3&gt;
  3245. &lt;p&gt;Like many browsers, Servo has two kinds of zoom: &lt;strong&gt;page zoom&lt;/strong&gt; affects the size of the viewport, while &lt;strong&gt;pinch zoom&lt;/strong&gt; does not (&lt;a href=&quot;https://github.com/shubhamg13&quot;&gt;@shubhamg13&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38194&quot;&gt;#38194&lt;/a&gt;).
  3246. &lt;strong&gt;Page zoom&lt;/strong&gt; now correctly triggers reflow (&lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38166&quot;&gt;#38166&lt;/a&gt;), and &lt;strong&gt;pinch zoom&lt;/strong&gt; is now reset to the viewport meta config when navigating (&lt;a href=&quot;https://github.com/shubhamg13&quot;&gt;@shubhamg13&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37315&quot;&gt;#37315&lt;/a&gt;).&lt;/p&gt;
  3247. &lt;p&gt;&lt;strong&gt;‘image-rendering’ property&lt;/strong&gt; now affects &lt;strong&gt;‘border-image’&lt;/strong&gt; (&lt;a href=&quot;https://github.com/lumiscosity&quot;&gt;@lumiscosity&lt;/a&gt;, &lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38346&quot;&gt;#38346&lt;/a&gt;), &lt;strong&gt;‘text-decoration[-line]’&lt;/strong&gt; is now &lt;strong&gt;drawn under whitespace&lt;/strong&gt; (&lt;a href=&quot;https://github.com/leo030303&quot;&gt;@leo030303&lt;/a&gt;, &lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38007&quot;&gt;#38007&lt;/a&gt;), and we’ve also fixed several layout bugs around &lt;strong&gt;grid item contents&lt;/strong&gt; (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37981&quot;&gt;#37981&lt;/a&gt;), &lt;strong&gt;table cell contents&lt;/strong&gt; (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38290&quot;&gt;#38290&lt;/a&gt;), &lt;strong&gt;quirks mode&lt;/strong&gt; (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37814&quot;&gt;#37814&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37831&quot;&gt;#37831&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37820&quot;&gt;#37820&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37837&quot;&gt;#37837&lt;/a&gt;), &lt;strong&gt;clientWidth&lt;/strong&gt; and &lt;strong&gt;clientHeight&lt;/strong&gt; queries of grid layouts (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37917&quot;&gt;#37917&lt;/a&gt;), and &lt;strong&gt;‘min-height’&lt;/strong&gt; and &lt;strong&gt;‘max-height’&lt;/strong&gt; of replaced elements (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37758&quot;&gt;#37758&lt;/a&gt;).&lt;/p&gt;
  3248. &lt;p&gt;As part of our &lt;strong&gt;incremental layout&lt;/strong&gt; project, we now &lt;strong&gt;cache the layout results&lt;/strong&gt; of replaced boxes (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37971&quot;&gt;#37971&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37897&quot;&gt;#37897&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37962&quot;&gt;#37962&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37943&quot;&gt;#37943&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37985&quot;&gt;#37985&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38349&quot;&gt;#38349&lt;/a&gt;), &lt;strong&gt;avoid unnecessary reflows&lt;/strong&gt; after animations (&lt;a href=&quot;https://github.com/coding-joedow&quot;&gt;@coding-joedow&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37954&quot;&gt;#37954&lt;/a&gt;), &lt;strong&gt;invalidate layouts more precisely&lt;/strong&gt; (&lt;a href=&quot;https://github.com/coding-joedow&quot;&gt;@coding-joedow&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38199&quot;&gt;#38199&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38057&quot;&gt;#38057&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38198&quot;&gt;#38198&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38059&quot;&gt;#38059&lt;/a&gt;), and we’ve added &lt;strong&gt;incremental box tree construction&lt;/strong&gt; (&lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/coding-joedow&quot;&gt;@coding-joedow&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37751&quot;&gt;#37751&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37957&quot;&gt;#37957&lt;/a&gt;) for flex and grid items (&lt;a href=&quot;https://github.com/coding-joedow&quot;&gt;@coding-joedow&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37854&quot;&gt;#37854&lt;/a&gt;), table columns, cells, and captions (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37851&quot;&gt;#37851&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37850&quot;&gt;#37850&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37849&quot;&gt;#37849&lt;/a&gt;), and a variety of inline elements (&lt;a href=&quot;https://github.com/coding-joedow&quot;&gt;@coding-joedow&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38084&quot;&gt;#38084&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37866&quot;&gt;#37866&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37868&quot;&gt;#37868&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37892&quot;&gt;#37892&lt;/a&gt;).&lt;/p&gt;
  3249. &lt;p&gt;Work on &lt;strong&gt;IndexedDB&lt;/strong&gt; continues, notably including support for &lt;strong&gt;key ranges&lt;/strong&gt; (&lt;a href=&quot;https://github.com/arihant2math&quot;&gt;@arihant2math&lt;/a&gt;, &lt;a href=&quot;https://github.com/jdm&quot;&gt;@jdm&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38268&quot;&gt;#38268&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37684&quot;&gt;#37684&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38278&quot;&gt;#38278&lt;/a&gt;).&lt;/p&gt;
  3250. &lt;p&gt;&lt;strong&gt;sessionStorage&lt;/strong&gt; is now isolated between webviews, and copied to new webviews with the same &lt;code&gt;opener&lt;/code&gt; (&lt;a href=&quot;https://github.com/janvarga&quot;&gt;@janvarga&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37803&quot;&gt;#37803&lt;/a&gt;).&lt;/p&gt;
  3251. &lt;h3&gt;Browser changes &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/08/22/this-month-in-servo/#browser-changes&quot;&gt;
  3252.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  3253.      &lt;/a&gt;&lt;/h3&gt;
  3254. &lt;p&gt;&lt;strong&gt;servoshell&lt;/strong&gt; now has a &lt;strong&gt;.desktop file&lt;/strong&gt; and &lt;strong&gt;window name&lt;/strong&gt;, so you can now &lt;strong&gt;pin it to your taskbar&lt;/strong&gt; on Linux (&lt;a href=&quot;https://github.com/MichaelMcDonnell&quot;&gt;@MichaelMcDonnell&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38038&quot;&gt;#38038&lt;/a&gt;).
  3255. We’ve made it more ergonomic too, fixing both the sluggish &lt;strong&gt;mouse wheel&lt;/strong&gt; and &lt;strong&gt;pixel-perfect trackpad scrolling&lt;/strong&gt; and the too fast &lt;strong&gt;arrow key scrolling&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37982&quot;&gt;#37982&lt;/a&gt;).&lt;/p&gt;
  3256. &lt;p&gt;You can now &lt;strong&gt;focus the location bar with Alt+D&lt;/strong&gt; in addition to Ctrl+L on non-macOS platforms (&lt;a href=&quot;https://github.com/MichaelMcDonnell&quot;&gt;@MichaelMcDonnell&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37794&quot;&gt;#37794&lt;/a&gt;), and &lt;strong&gt;clicking the location bar&lt;/strong&gt; now selects the contents (&lt;a href=&quot;https://github.com/MichaelMcDonnell&quot;&gt;@MichaelMcDonnell&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37839&quot;&gt;#37839&lt;/a&gt;).&lt;/p&gt;
  3257. &lt;p&gt;When debugging Servo &lt;a href=&quot;https://book.servo.org/hacking/using-devtools.html&quot;&gt;with the &lt;strong&gt;Firefox devtools&lt;/strong&gt;&lt;/a&gt;, you can now view requests in the &lt;strong&gt;Network tab&lt;/strong&gt; both &lt;strong&gt;after navigating&lt;/strong&gt; (&lt;a href=&quot;https://github.com/uthmaniv&quot;&gt;@uthmaniv&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37778&quot;&gt;#37778&lt;/a&gt;) and when &lt;strong&gt;responses are served from cache&lt;/strong&gt; (&lt;a href=&quot;https://github.com/uthmaniv&quot;&gt;@uthmaniv&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37906&quot;&gt;#37906&lt;/a&gt;).
  3258. We’re also implementing the &lt;strong&gt;Debugger tab&lt;/strong&gt; (&lt;a href=&quot;https://github.com/delan&quot;&gt;@delan&lt;/a&gt;, &lt;a href=&quot;https://github.com/atbrakhi&quot;&gt;@atbrakhi&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/36027&quot;&gt;#36027&lt;/a&gt;), including several changes to our script system (&lt;a href=&quot;https://github.com/delan&quot;&gt;@delan&lt;/a&gt;, &lt;a href=&quot;https://github.com/atbrakhi&quot;&gt;@atbrakhi&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38236&quot;&gt;#38236&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38232&quot;&gt;#38232&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38265&quot;&gt;#38265&lt;/a&gt;) and fixing a whole class of bugs where devtools ends up broken (&lt;a href=&quot;https://github.com/atbrakhi&quot;&gt;@atbrakhi&lt;/a&gt;, &lt;a href=&quot;https://github.com/delan&quot;&gt;@delan&lt;/a&gt;, &lt;a href=&quot;https://github.com/simonwuelker&quot;&gt;@simonwuelker&lt;/a&gt;, &lt;a href=&quot;https://github.com/the6p4c&quot;&gt;@the6p4c&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37686&quot;&gt;#37686&lt;/a&gt;).&lt;/p&gt;
  3259. &lt;h3&gt;WebDriver changes &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/08/22/this-month-in-servo/#webdriver-changes&quot;&gt;
  3260.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  3261.      &lt;/a&gt;&lt;/h3&gt;
  3262. &lt;p&gt;&lt;strong&gt;WebDriver automation&lt;/strong&gt; support now &lt;strong&gt;goes through servoshell&lt;/strong&gt;, rather than through libservo internally, ensuring that WebDriver commands are consistently executed in the correct order (&lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/PotatoCP&quot;&gt;@PotatoCP&lt;/a&gt;, &lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37669&quot;&gt;#37669&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37908&quot;&gt;#37908&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37663&quot;&gt;#37663&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37911&quot;&gt;#37911&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38212&quot;&gt;#38212&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38314&quot;&gt;#38314&lt;/a&gt;).
  3263. We’ve also fixed race conditions in the &lt;strong&gt;Back&lt;/strong&gt;, &lt;strong&gt;Forward&lt;/strong&gt; (&lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/jdm&quot;&gt;@jdm&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37950&quot;&gt;#37950&lt;/a&gt;), &lt;strong&gt;Element Click&lt;/strong&gt; (&lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37935&quot;&gt;#37935&lt;/a&gt;), &lt;strong&gt;Switch To Window&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38160&quot;&gt;#38160&lt;/a&gt;), and other commands (&lt;a href=&quot;https://github.com/PotatoCP&quot;&gt;@PotatoCP&lt;/a&gt;, &lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38079&quot;&gt;#38079&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38234&quot;&gt;#38234&lt;/a&gt;).&lt;/p&gt;
  3264. &lt;p&gt;We’ve added support for the &lt;strong&gt;Dismiss Alert&lt;/strong&gt;, &lt;strong&gt;Accept Alert&lt;/strong&gt;, &lt;strong&gt;Get Alert Text&lt;/strong&gt; (&lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37913&quot;&gt;#37913&lt;/a&gt;), and &lt;strong&gt;Send Alert Text&lt;/strong&gt; commands for &lt;a href=&quot;https://html.spec.whatwg.org/multipage/#simple-dialogs&quot;&gt;&lt;strong&gt;simple dialogs&lt;/strong&gt;&lt;/a&gt; (&lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38140&quot;&gt;#38140&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38035&quot;&gt;#38035&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38142&quot;&gt;#38142&lt;/a&gt;), as well as the &lt;strong&gt;Maximize Window&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38271&quot;&gt;#38271&lt;/a&gt;) and &lt;strong&gt;Element Clear&lt;/strong&gt; commands (&lt;a href=&quot;https://github.com/PotatoCP&quot;&gt;@PotatoCP&lt;/a&gt;, &lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/jdm&quot;&gt;@jdm&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38208&quot;&gt;#38208&lt;/a&gt;).
  3265. &lt;a href=&quot;https://w3c.github.io/webdriver/#element-retrieval&quot;&gt;&lt;strong&gt;Find Element&lt;/strong&gt; family of commands&lt;/a&gt; can now use the &lt;strong&gt;&lt;code&gt;&quot;xpath&quot;&lt;/code&gt; location strategy&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37783&quot;&gt;#37783&lt;/a&gt;).
  3266. &lt;strong&gt;Get Element Shadow Root&lt;/strong&gt; commands can now interact with &lt;strong&gt;closed shadow roots&lt;/strong&gt; (&lt;a href=&quot;https://github.com/PotatoCP&quot;&gt;@PotatoCP&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37826&quot;&gt;#37826&lt;/a&gt;).&lt;/p&gt;
  3267. &lt;p&gt;You can now &lt;strong&gt;run the WebDriver test suite&lt;/strong&gt; in CI with &lt;code&gt;mach try wd&lt;/code&gt; or &lt;code&gt;mach try webdriver&lt;/code&gt; (&lt;a href=&quot;https://github.com/PotatoCP&quot;&gt;@PotatoCP&lt;/a&gt;, &lt;a href=&quot;https://github.com/sagudev&quot;&gt;@sagudev&lt;/a&gt;, &lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37498&quot;&gt;#37498&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37873&quot;&gt;#37873&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37712&quot;&gt;#37712&lt;/a&gt;).&lt;/p&gt;
  3268. &lt;h3&gt;2D graphics &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/08/22/this-month-in-servo/#2d-graphics&quot;&gt;
  3269.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  3270.      &lt;/a&gt;&lt;/h3&gt;
  3271. &lt;p&gt;&lt;strong&gt;&amp;lt;canvas&amp;gt;&lt;/strong&gt; is key to programmable graphics on the web, with Servo supporting WebGPU, WebGL, and 2D canvas contexts.
  3272. But the &lt;strong&gt;general-purpose 2D graphics&lt;/strong&gt; routines that power Servo’s 2D canvases are potentially useful for a lot more than &amp;lt;canvas&amp;gt;: &lt;strong&gt;font rendering&lt;/strong&gt; is bread and butter for Servo, but &lt;strong&gt;SVG rendering&lt;/strong&gt; is only minimally supported right now, and &lt;strong&gt;PDF output&lt;/strong&gt; is not yet implemented at all.&lt;/p&gt;
  3273. &lt;p&gt;Those features have one thing in common: they require things that WebRender can’t yet do.
  3274. &lt;strong&gt;WebRender&lt;/strong&gt; does one thing and does it well: rasterise the layouts of the web, really fast, by &lt;a href=&quot;https://hacks.mozilla.org/2017/10/the-whole-web-at-maximum-fps-how-webrender-gets-rid-of-jank/&quot;&gt;using the GPU as much as possible&lt;/a&gt;.
  3275. Font rendering and SVG rendering both involve rasterising arbitrary paths, which currently has to be done outside WebRender, and PDF output is out of scope entirely.&lt;/p&gt;
  3276. &lt;p&gt;The more code we can share between these tasks, the better we can make that code, and the smaller we can make Servo’s binary sizes (&lt;a href=&quot;https://github.com/servo/servo/issues/38022&quot;&gt;#38022&lt;/a&gt;).
  3277. We’ve started by moving 2D-&amp;lt;canvas&amp;gt;-specific state out of the &lt;code&gt;canvas&lt;/code&gt; crate (&lt;a href=&quot;https://github.com/sagudev&quot;&gt;@sagudev&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38098&quot;&gt;#38098&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38114&quot;&gt;#38114&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38164&quot;&gt;#38164&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38214&quot;&gt;#38214&lt;/a&gt;), which has in turn allowed us to modernise it with &lt;strong&gt;new backends based on &lt;a href=&quot;https://github.com/linebender/vello&quot;&gt;Vello&lt;/a&gt;&lt;/strong&gt; (&lt;a href=&quot;https://github.com/EnnuiL&quot;&gt;@EnnuiL&lt;/a&gt;, &lt;a href=&quot;https://github.com/sagudev&quot;&gt;@sagudev&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/30636&quot;&gt;#30636&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/38345&quot;&gt;#38345&lt;/a&gt;):&lt;/p&gt;
  3278. &lt;ul&gt;
  3279. &lt;li&gt;
  3280. &lt;p&gt;a Vello GPU-based backend (&lt;a href=&quot;https://github.com/sagudev&quot;&gt;@sagudev&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/36821&quot;&gt;#36821&lt;/a&gt;), currently slower than the default backend; to use it, build Servo with &lt;code&gt;--features vello&lt;/code&gt; and enable it with &lt;code&gt;--pref dom_canvas_vello_enabled&lt;/code&gt;&lt;/p&gt;
  3281. &lt;/li&gt;
  3282. &lt;li&gt;
  3283. &lt;p&gt;a Vello CPU-based backend (&lt;a href=&quot;https://github.com/sagudev&quot;&gt;@sagudev&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38282&quot;&gt;#38282&lt;/a&gt;), &lt;strong&gt;already faster than the default backend&lt;/strong&gt;; to use it, build Servo with &lt;code&gt;--features vello_cpu&lt;/code&gt; and enable it with &lt;code&gt;--pref dom_canvas_vello_cpu_enabled&lt;/code&gt;&lt;/p&gt;
  3284. &lt;/li&gt;
  3285. &lt;/ul&gt;
  3286. &lt;h3&gt;What is a pixel? &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/08/22/this-month-in-servo/#what-is-a-pixel%3F&quot;&gt;
  3287.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  3288.      &lt;/a&gt;&lt;/h3&gt;
  3289. &lt;p&gt;Many recent Servo bugs have been related to our handling of &lt;strong&gt;viewport&lt;/strong&gt;, &lt;strong&gt;window&lt;/strong&gt;, and &lt;strong&gt;screen coordinate spaces&lt;/strong&gt; (&lt;a href=&quot;https://github.com/servo/servo/issues/36817&quot;&gt;#36817&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/37804&quot;&gt;#37804&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/37824&quot;&gt;#37824&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/37878&quot;&gt;#37878&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/37978&quot;&gt;#37978&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/38089&quot;&gt;#38089&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/38090&quot;&gt;#38090&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/38093&quot;&gt;#38093&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/issues/38255&quot;&gt;#38255&lt;/a&gt;).
  3290. Symptoms of these bugs include &lt;strong&gt;bad hit testing&lt;/strong&gt; (e.g. links that can’t be clicked), &lt;strong&gt;inability to scroll&lt;/strong&gt; to the end of the page, or &lt;strong&gt;graphical glitches&lt;/strong&gt; like disappearing browser UI or black bars.&lt;/p&gt;
  3291. &lt;p&gt;Windows rarely take up the whole screen, viewports rarely take up the whole window due to window decorations, and when different units come into play, like CSS &lt;code&gt;px&lt;/code&gt; vs device pixels, a more systematic approach is needed.
  3292. We built &lt;a href=&quot;https://docs.rs/euclid/0.22.11/euclid/&quot;&gt;&lt;strong&gt;euclid&lt;/strong&gt;&lt;/a&gt; to solve these problems in a strongly typed way within Servo, but beyond the viewport, we need to convert between euclid types and the geometry types provided by the embedder, the toolkit, the platform, or WebDriver, which creates opportunities for errors.&lt;/p&gt;
  3293. &lt;p&gt;Embedders are now the single source of truth for &lt;strong&gt;window rects&lt;/strong&gt; and &lt;strong&gt;screen sizes&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37960&quot;&gt;#37960&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38020&quot;&gt;#38020&lt;/a&gt;), and we’ve fixed incorrect coordinate handling in &lt;a href=&quot;https://w3c.github.io/webdriver/#get-window-rect&quot;&gt;&lt;strong&gt;Get Window Rect&lt;/strong&gt;&lt;/a&gt;, &lt;a href=&quot;https://w3c.github.io/webdriver/#set-window-rect&quot;&gt;&lt;strong&gt;Set Window Rect&lt;/strong&gt;&lt;/a&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37812&quot;&gt;#37812&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37893&quot;&gt;#37893&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38209&quot;&gt;#38209&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38258&quot;&gt;#38258&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38249&quot;&gt;#38249&lt;/a&gt;), &lt;strong&gt;resizeTo()&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37848&quot;&gt;#37848&lt;/a&gt;), &lt;strong&gt;screenX&lt;/strong&gt;, &lt;strong&gt;screenY&lt;/strong&gt;, &lt;strong&gt;screenLeft&lt;/strong&gt;, &lt;strong&gt;screenTop&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37934&quot;&gt;#37934&lt;/a&gt;), and in &lt;strong&gt;servoshell&lt;/strong&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37961&quot;&gt;#37961&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38174&quot;&gt;#38174&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38307&quot;&gt;#38307&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38082&quot;&gt;#38082&lt;/a&gt;).
  3294. We’ve also improved the Web Platform Tests (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37856&quot;&gt;#37856&lt;/a&gt;) and clarified our docs (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37879&quot;&gt;#37879&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/38110&quot;&gt;#38110&lt;/a&gt;) in these areas.&lt;/p&gt;

  3318. <title>The Mozilla Blog: What I learned when I stopped posting my life online, from a former influencer</title>

  3320. <link>https://blog.mozilla.org/en/internet-culture/former-influencer/</link>
  3321. <description>&lt;div class=&quot;wp-block-image&quot;&gt;
  3322. &lt;figure class=&quot;aligncenter size-large is-resized&quot;&gt;&lt;img alt=&quot;Woman with orange hair in peach coat and floral bag standing by blooming tree.&quot; class=&quot;wp-image-81481&quot; height=&quot;1024&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/08/lindsey-1-819x1024.webp&quot; style=&quot;width: 650px;&quot; width=&quot;819&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;During my influencer and blogging era, 2016. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;&lt;/div&gt;
  3323.  
  3324.  
  3325. &lt;p&gt;&lt;em&gt;This essay was originally published on &lt;a href=&quot;https://mozillasidebar.substack.com/p/what-i-learned-when-i-stopped-posting&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;The Sidebar, Mozilla’s Substack&lt;/a&gt;.&lt;/em&gt;&lt;/p&gt;
  3326.  
  3327.  
  3328.  
  3329. &lt;p&gt;I was an influencer years before it &lt;a href=&quot;https://www.dictionary.com/e/influencer/&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;became mainstream in 2016&lt;/a&gt;. I shared my outfits on my fashion blog almost daily, along with recipes, travel itineraries, lifestyle photos, you name it. My blog upheld a twee aesthetic that I stuck to religiously. I made content (it wasn’t called that yet), curated an aesthetic (it also wasn’t called that yet) and blurred the lines between what was real and what was for the curated version of me. I was good at it and made money from sponsored content and paid ads. But I learned how overcurating can affect every part of your life. &lt;/p&gt;
  3330.  
  3331.  
  3332.  
  3333. &lt;p&gt;I was always thinking about the shot I needed to get, if a restaurant was going to match my aesthetic, or if I needed to go thrifting to purchase new clothes because I had gone through most of my clothes in my previous blog posts. In the early 2010s, blogs that did well were a one-stop-shop for all lifestyle content. It was a lot of work, but that’s what I strived for.&lt;/p&gt;
  3334.  
  3335.  
  3336.  
  3337. &lt;p&gt;I was an influencer when the term was just “blogger” and things were slower, but I never felt that. I struggled to keep up even with caffeine pills, being in my early 20s with a lot of energy and finding out that I liked being online and enjoyed it there. But by the time the term “influencer” entered common conversations among coworkers and family, I was burnt out. I was over it, exhausted from overcurating my life. So I decided to stop posting.&lt;/p&gt;
  3338.  
  3339.  
  3340.  
  3341. &lt;h3&gt;Lesson 1: The best photos aren’t staged&lt;/h3&gt;
  3342.  
  3343.  
  3344.  
  3345. &lt;p&gt;I kept my website up for a while, then shut it down completely. Going “offline,” I found that the best photos are the ones that are not staged, and you will find yourself with the most beautiful pictures of yourself. Of course we all know this, we all want those curated photo dumps for Instagram and candid shots of us just looking carefree… but what I’m saying is stop asking for photos altogether. Let people take pictures of you unasked. The best photos of myself were during the years I was offline because I didn’t think about any photos in the same way. These were pictures I didn’t ask for, therefore I wouldn’t have that many to choose from. It felt almost like film pictures I developed, I had to pick from one or two. &lt;/p&gt;
  3346.  
  3347.  
  3348.  
  3349. &lt;h3&gt;Lesson 2: Hobbies hit different&lt;/h3&gt;
  3350.  
  3351.  
  3352.  
  3353. &lt;p&gt;I also found that you have a lot more free time when you don’t have to be online. I still scrolled sometimes, I still read blogs, I still downloaded TikTok in 2020, but I didn’t feel the need to scroll in the same way. When I was offline, I was only scrolling for pleasure like finding videos of a Furbie cult or Calico Critters collector drama.&lt;/p&gt;
  3354.  
  3355.  
  3356.  
  3357. &lt;figure class=&quot;wp-block-pullquote&quot;&gt;&lt;blockquote&gt;&lt;p&gt;Going ‘offline,’ I found that the best photos are the ones that are not staged, and you will find the most beautiful pictures of yourself.&lt;/p&gt;&lt;/blockquote&gt;&lt;/figure&gt;
  3358.  
  3359.  
  3360.  
  3361. &lt;p&gt;But when I was blogging, and when I got back online for Tiktok and my Substack, I was scrolling for strategy. I needed to know what current trends I should talk about or follow, and I felt if I missed something online it could hurt my credibility. When I stopped blogging, I almost didn’t know what to do with my extra time – I’m a girl with hobbies and friends and I was in my 20s, so this says a lot! I spent so long curating my online presence, picking out outfits, planning photoshoots, and replying to emails (not even to mention actual blogging!) that I had SO much free time. I could actually focus on my hobbies… for me. I didn’t need to take photos of everything nor look at the menu of the restaurant before I went. Over time I got used to it and loved it. I no longer had to collect stamps or postcards, which was just something I did for my blog. I even took up new hobbies, ones that couldn’t be translated into my blog or online, like watching anime and learning how to work a grill. Camping was not aesthetic enough for my blog, though I still went when I was blogging. After quitting I felt like I could go more often, because there was no post being counted on that weekend. I could do whatever I wanted without the fear of “what will I post?” &lt;/p&gt;
  3362.  
  3363.  
  3364.  
  3365. &lt;figure class=&quot;wp-block-image aligncenter size-full&quot;&gt;&lt;img alt=&quot;Smiling woman in bright yellow dress with sunglasses standing in sunny green field.&quot; class=&quot;wp-image-81491&quot; height=&quot;512&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/08/lindsey-2.png&quot; width=&quot;384&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;In 2020, after I had been offline for a few years and before joining TikTok.
  3366. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  3367.  
  3368.  
  3369.  
  3370. &lt;h3&gt;Lesson 3: Your personal style will change&lt;/h3&gt;
  3371.  
  3372.  
  3373.  
  3374. &lt;p&gt;It’s been said that people can tell how much screentime you spend by how you dress, and I agree. If you are wearing everything trending, experimenting with the cutting edge micro trends and aesthetics, you are definitely online and probably online a lot. There is nothing wrong with that (besides overconsumption, but that is for a different topic), but when you exit an online space you exit those types of information. While blogging I was wearing tons of layers, everything pre-1980s vintage, and uncomfortable hats and fabrics. I bought my first pair of athletic leggings with pockets after I quit blogging and I wondered why I deprived myself of this type of comfort for so long. You will be dressing for you and those only physically around you, not other people online and not trying to go viral. It will be different and you should embrace that. It’s a luxury not everyone has. &lt;/p&gt;
  3375.  
  3376.  
  3377.  
  3378. &lt;h3&gt;Lesson 4: You learn the things you actually enjoy, and those you don’t &lt;/h3&gt;
  3379.  
  3380.  
  3381.  
  3382. &lt;p&gt;It took time to adjust to being offline, but those times might have been my happiest. Nothing felt calculated anymore. Once you stop posting, you’re not in the public eye in the same way. I didn’t worry if someone in my city recognized me at the grocery store in my pjs and hungover. I started being sillier. I decided to use some extra time I had to write more poetry and do readings at local venues. It took a while for me to realize this, but after I took down my blog there was no real trace of me. I could be anyone. I was just Lindsey. Not Lindsey the fashion blogger, just Lindsey.&lt;/p&gt;
  3383.  
  3384.  
  3385.  
  3386. &lt;figure class=&quot;wp-block-pullquote&quot;&gt;&lt;blockquote&gt;&lt;p&gt;&lt;em&gt;I started being sillier. I decided to use some extra time I had to write more poetry and do readings at local venues. It took a while for me to realize this, but after I took down my blog there was no real trace of me. I could be anyone. I was just Lindsey. Not Lindsey the fashion blogger, just Lindsey.&lt;/em&gt;&lt;br /&gt;&lt;/p&gt;&lt;/blockquote&gt;&lt;/figure&gt;
  3387.  
  3388.  
  3389.  
  3390. &lt;p&gt;Now you have permission to cut out what you don’t really like. I hated selling vintage clothing, which was part of how I made money with my blog. I would buy so many clothes so I could wear new items in my posts. It was very time consuming. Vintage reselling can be exploitative and I didn’t like that. I also really did not like the way I dressed anymore. My readers responded the best to very “true vintage” looks (all items at least 20 years old) and I had been over that for years. I liked vintage band tees, leopard print, and chain link necklaces at this point. When I wore different looks, my views went down. My collabs, how I made money, were usually with vintage-inspired fashion companies, so I couldn’t change my look or I would lose money. I didn’t feel like rebranding myself either. But I changed my style anyway.&lt;/p&gt;
  3391.  
  3392.  
  3393.  
  3394. &lt;p&gt;When I quit blogging and influencing, I realized how unhappy I was. I was chasing cheap dopamine and working 24/7 to barely make ends meet, and while it was fun for a while, it was only for a while. &lt;/p&gt;
  3395.  
  3396.  
  3397.  
  3398. &lt;p&gt;Around December 2023, I went back “online” and started posting regularly on TikTok. I told myself it would always be about the things I say, what I want to wear, and what I want to write – never chasing paid sponsorship or selling clothes to my followers. Although, you cannot escape thinking about the algorithm if you are online and making money and funding a career. But I know the boundaries and what life is like when I’m not creating content. I specifically choose not to do “influencing” when coming online again because when I’m not trying to sell myself to brands, I can truly be myself. For me, creating content is a job, not a lifestyle. Ultimately, I’m building a life I just want to be in — online or not.&lt;/p&gt;

  3484. &lt;p&gt;An important step for RFC implementation is for people to experiment with the
  3485. implementation and give feedback, especially before stabilization.&lt;/p&gt;
  3486. &lt;p&gt;If you are a feature implementer and would like your RFC to appear in this list, add a
  3487. &lt;code&gt;call-for-testing&lt;/code&gt; label to your RFC along with a comment providing testing instructions and/or
  3488. guidance on which aspect(s) of the feature need testing.&lt;/p&gt;
  3489. &lt;ul&gt;

  3906. &lt;p&gt;It's amazing how far const eval has come in #Rust. It wasn't too long ago that even a simple if/else wasn't permitted. Now we're not that far off from having const trait impls and const closures, which will make damn near everything const capable.&lt;/p&gt;

  3918. <title>Mozilla Thunderbird: Thunderbird Pro August 2025 Update</title>
  3919. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3734</guid>
  3920. <link>https://blog.thunderbird.net/2025/08/tbpro-august-2025-update/</link>
  3921. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;320&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/tb-pro-blog.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  3922. &lt;p&gt;In April of this year &lt;a href=&quot;https://blog.thunderbird.net/2025/04/thundermail-and-thunderbird-pro-services/&quot;&gt;we announced Thunderbird Pro&lt;/a&gt;, additional subscription services from Thunderbird meant to help you get more done with the app you already use and love. These services include a first ever email service from Thunderbird, called Thundermail. They also include Appointment, for scheduling meetings and appointments and Send, an end-to-end encrypted filesharing tool. &lt;strong&gt;Each of these services are open source, repositories are linked down below.&lt;/strong&gt;&lt;/p&gt;
  3923.  
  3924.  
  3925.  
  3926. &lt;p&gt;Thunderbird Pro services are being built as part of the broader Thunderbird product ecosystem. These services are enhancements to the current Thunderbird application experience. They are optional, designed to enhance productivity for users who need features like scheduling, file sharing and email hosting, without relying on the alternate platforms. For users who opt in, the goal is for these services to be smoothly integrated into the Thunderbird app, providing a natural extension of the familiar experience they already enjoy, enhanced with additional capabilities they may be looking for. For updates on Thunderbird Pro development and beta access availability, &lt;a href=&quot;https://thundermail.com/&quot;&gt;sign &lt;/a&gt;up for the mailing list at &lt;a href=&quot;http://thundermail.com&quot;&gt;thundermail.com&lt;/a&gt;. &lt;/p&gt;
  3927.  
  3928.  
  3929.  
  3930. &lt;h3&gt;&lt;strong&gt;Progress So Far&lt;/strong&gt;&lt;/h3&gt;
  3931.  
  3932.  
  3933.  
  3934. &lt;h4&gt;Thundermail&lt;/h4&gt;
  3935.  
  3936.  
  3937.  
  3938. &lt;p&gt;Development has been moving steadily forward and community interest in Thundermail has been strong. The upcoming email hosting service from Thunderbird will support IMAP, SMTP and JMAP out of the box, making it compatible with the Thunderbird app and many other email clients. If you have your own domain, you’ll be able to bring it in and host it with us. Alternatively, grab an email address provided by Thunderbird with your choice of @thundermail.com or @tb.pro as the domains.  The servers hosting Thundermail will initially be located in Germany with more countries to follow in the future. Thunderbird’s investment in offering an email service reflects our broader goal of strengthening support for open standards and giving users the option to keep their entire email experience within Thunderbird. &lt;/p&gt;
  3939.  
  3940.  
  3941.  
  3942. &lt;h4&gt;Thunderbird Appointment &lt;a href=&quot;https://github.com/thunderbird/appointment&quot;&gt;(Repo)&lt;/a&gt;&lt;/h4&gt;
  3943.  
  3944.  
  3945.  
  3946. &lt;p&gt;We originally developed the scheduling tool as a standalone web app. On the current roadmap, however, we’re tightly integrating Appointment into the Thunderbird app through the compose window, allowing users to insert scheduling links without leaving the email workflow. It will be easy for organizations and individuals to self-host, fork and adapt the tool to their own needs. The future is for Appointment to support multiple meeting types, like Zoom calls, phone meetings, or in-person coffee chats. Each of these will have its own settings and scheduling rules. &lt;/p&gt;
  3947.  
  3948.  
  3949.  
  3950. &lt;p&gt;One of the most requested future features is group scheduling, which would allow multiple team members to offer shared availability via a single link. The current calendar protocols don’t fully support this flow, however Thunderbird is participating in discussions around open standards like VPOLL to help move things forward. Usability studies are helping refine the MVP and community feedback is shaping the roadmap.&lt;/p&gt;
  3951.  
  3952.  
  3953.  
  3954. &lt;h4&gt;Thunderbird Send &lt;a href=&quot;https://github.com/thunderbird/tbpro-add-on&quot;&gt;(Repo)&lt;/a&gt;&lt;/h4&gt;
  3955.  
  3956.  
  3957.  
  3958. &lt;p&gt;A secure, end-to-end encrypted file sharing tool, built on Thunderbird app’s existing Filelink feature. It supports large file transfers directly from the email client. This allows users to bypass platforms like Google Drive or OneDrive. Pro users will receive 500 GB of storage to start, with no individual file size limit, only constrained by their total quota. We’re planning support for chunked uploads and encryption  to ensure reliability and data protection. We’ll deliver Send as a system add-on which lets the team push updates faster. This also avoids locking new capabilities behind major Thunderbird release cycles.&lt;/p&gt;
  3959.  
  3960.  
  3961.  
  3962. &lt;p&gt;All Thunderbird Pro tools are open source and self-hostable. For users who prefer to run their own infrastructure or work in regulated environments, both Send and Appointment can be deployed independently. Thunderbird will continue to support these users with documentation and open APIs.&lt;/p&gt;
  3963.  
  3964.  
  3965.  
  3966. &lt;h3&gt;&lt;strong&gt;A Look Ahead&lt;/strong&gt;&lt;/h3&gt;
  3967.  
  3968.  
  3969.  
  3970. &lt;p&gt;Thunderbird is exploring additional Pro features beyond the current lineup. While we’ve made no commitments yet, there is strong interest in adding markdown based Notes functionality, especially as lightweight personal knowledge management becomes more popular. Heavier lifts like collaborative docs or spreadsheets may follow, depending on adoption and sustainability.&lt;/p&gt;
  3971.  
  3972.  
  3973.  
  3974. &lt;p&gt;Another worthy mention: a fourth, previously announced service called Assist, which will eventually enable users to take advantage of AI features in their day-to-day email tasks, is still in the research and development phase. It will not be part of the initial lineup of services. This initiative is a bigger undertaking as we ensure we get it right for user privacy and make sure the features included are actually things our users want. More to come on this as the project progresses.&lt;/p&gt;
  3975.  
  3976.  
  3977.  
  3978. &lt;p&gt;To improve transparency and invite community collaboration, Thunderbird is also preparing a public roadmap covering desktop, mobile and Pro services. We’re developing the roadmap in collaboration with the Thunderbird Council. Our goal is to encourage participation from contributors and users alike.&lt;/p&gt;
  3979.  
  3980.  
  3981.  
  3982. &lt;h4&gt;Free vs Paid&lt;/h4&gt;
  3983.  
  3984.  
  3985.  
  3986. &lt;p&gt;Adding these additional subscription services will never compromise the features, stability or functionality our users are accustomed to in the free Thunderbird desktop and mobile applications. These services come with real costs, especially storage and bandwidth. Charging for them helps ensure that users who benefit from these tools help cover their cost, instead of donors footing the bill. &lt;/p&gt;
  3987.  
  3988.  
  3989.  
  3990. &lt;p&gt;Thunderbird Pro is a completely optional suite of (open source) services designed to provide additional productivity capabilities to the Thunderbird app and never to replace them. The current Thunderbird desktop and mobile applications are, and always will be, free. They will still heavily rely on ongoing donations for both development and independence.&lt;/p&gt;
  3991.  
  3992.  
  3993.  
  3994. &lt;p&gt;If you haven’t already, j&lt;a href=&quot;https://thundermail.com/&quot;&gt;oin our waiting list&lt;/a&gt; to be one of the early beta testers for Thunderbird Pro. While we don’t have a specific timeline just yet, we will be sharing ongoing updates as development progresses.&lt;/p&gt;
  3995.  
  3996.  
  3997.  
  3998. &lt;p&gt;—&lt;/p&gt;

  4008. <title>The Mozilla Blog: Fast, private and secure (pick three): Introducing CRLite in Firefox</title>
  4009. <guid isPermaLink="false">https://blog.mozilla.org/?p=81467</guid>
  4010. <link>https://blog.mozilla.org/en/firefox/crlite/</link>
  4011. <description>&lt;p&gt;We are pleased to announce that Firefox 142 will begin production usage of our brand new certificate revocation system known as CRLite. CRLite makes your browsing faster, more private, and more secure, and is a significant advancement to the state of the art for encryption on the internet.&lt;/p&gt;
  4012.  
  4013.  
  4014.  
  4015. &lt;p&gt;Every day, billions of people rely on HTTPS to securely encrypt their communication with websites. This core protocol ensures both that you are communicating with the right website and that other parties can’t spy on what you’re doing. To make this work, websites obtain &lt;em&gt;certificates&lt;/em&gt; from trusted organizations to prove to browsers like Firefox that they are who they say they are. However, mistakes happen: a certificate can be mis-issued to the wrong party, or compromised by a malicious actor. When this happens, the certificate must be &lt;em&gt;revoked&lt;/em&gt; so that browsers know it is no longer trustworthy. Communicating this information to browsers is a surprisingly hard problem — all previous methods have had to make tradeoffs between privacy, security, and performance.&lt;/p&gt;
  4016.  
  4017.  
  4018.  
  4019. &lt;p&gt;Mozilla stands for a web where users shouldn’t have to make these tradeoffs — &lt;a href=&quot;https://www.mozilla.org/en-US/about/webvision/full/#ubiquitousencryption&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;encryption&lt;/a&gt;, &lt;a href=&quot;https://www.mozilla.org/en-US/about/webvision/full/#privacy&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;privacy&lt;/a&gt; and &lt;a href=&quot;https://www.mozilla.org/en-US/about/webvision/full/#performance&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;performance&lt;/a&gt; are cornerstones of our vision for the web, and it’s our mission to build technology that gives users all three without compromise.&lt;/p&gt;
  4020.  
  4021.  
  4022.  
  4023. &lt;p&gt;CRLite represents a multiyear effort to deliver this vision with a comprehensive system that operates entirely on-device. This eliminates the need for online revocation checks, which both slow down page loads and leak the sites you’re visiting to third parties on the network. Other browsers have deployed similar approaches, but these systems have only been able to store a small fraction of all revoked certificates, necessitating imperfect guesswork as to which ones are most important. CRLite is efficient enough to store &lt;em&gt;all&lt;/em&gt; certificate revocations locally, requiring only 300KB per day of continuous updates to stay current.&lt;/p&gt;
  4024.  
  4025.  
  4026.  
  4027. &lt;p&gt;CRLite uses a number of clever algorithms and techniques to achieve its performance, and we are grateful to all the individuals inside and outside Mozilla who contributed insight and code to make it all work. You can find more technical details in the accompanying &lt;a href=&quot;https://hacks.mozilla.org/2025/08/crlite-fast-private-and-comprehensive-certificate-revocation-checking-in-firefox/&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;Hacks post&lt;/a&gt; by lead engineer John Schanck, as well as in our recently published &lt;a href=&quot;https://research.mozilla.org/files/2025/04/clubcards_for_the_webpki.pdf&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;paper&lt;/a&gt;.&lt;/p&gt;
  4028.  
  4029.  
  4030.  
  4031. &lt;p&gt;CRLite sets a new standard for revocation security that you’ll only find in Firefox today. We’re proud of that, but we actually hope it doesn’t stay that way. Our mission is to make the internet safer for everyone, and that means we want to see this level of security deployed everywhere, not just in Firefox. We’ve designed CRLite to be easy for other browsers and internet clients to adopt or adapt, and look forward to comprehensive revocation checking becoming the norm everywhere.&lt;/p&gt;

  4046. <title>Hacks.Mozilla.Org: CRLite: Fast, private, and comprehensive certificate revocation checking in Firefox</title>
  4047. <guid isPermaLink="false">https://hacks.mozilla.org/?p=48231</guid>
  4048. <link>https://hacks.mozilla.org/2025/08/crlite-fast-private-and-comprehensive-certificate-revocation-checking-in-firefox/</link>
  4049. <description>&lt;p&gt;Firefox is now the first and the only browser to deploy fast and comprehensive certificate revocation checking that does not reveal your browsing activity to anyone (not even to Mozilla).&lt;/p&gt;
  4050. &lt;p&gt;Tens of millions of TLS server certificates are issued each day to secure communications between browsers and websites. These certificates are the cornerstones of &lt;a href=&quot;https://www.mozilla.org/en-US/about/webvision/full/#ubiquitousencryption&quot;&gt;ubiquitous encryption&lt;/a&gt; and a key part of our vision for the web. While a certificate can be valid for up to 398 days, it can also be revoked at any point in its lifetime. A revoked certificate poses a serious security risk and should not be trusted to authenticate a server.&lt;/p&gt;
  4051. &lt;p&gt;Identifying a revoked certificate is difficult because information needs to flow from the &lt;a href=&quot;https://en.wikipedia.org/wiki/Certificate_authority&quot;&gt;certificate’s issuer&lt;/a&gt; out to each browser. There are basically two ways to handle this. The browser either needs to ask an authority in real time about each certificate that it encounters, or it needs to maintain a frequently-updated list of revoked certificates. Firefox’s new mechanism, CRLite, has made the latter strategy feasible for the first time.&lt;/p&gt;
  4052. &lt;p&gt;With CRLite, Firefox periodically downloads a compact encoding of the set of all revoked certificates that appear in &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/Security/Certificate_Transparency&quot;&gt;Certificate Transparency logs&lt;/a&gt;. Firefox stores this encoding locally, updates it every 12 hours, and queries it privately every time a new TLS connection is created.&lt;/p&gt;
  4053. &lt;p&gt;You may have heard that &lt;a href=&quot;https://scotthelme.co.uk/revocation-is-broken/&quot;&gt;revocation is broken&lt;/a&gt; or that &lt;a href=&quot;https://www.imperialviolet.org/2011/03/18/revocation.html&quot;&gt;revocation doesn’t work&lt;/a&gt;. For a long time, the web was stuck with bad tradeoffs between security, privacy, and reliability in this space. That’s no longer the case. We enabled CRLite for all Firefox desktop (Windows, Linux, MacOS) users starting in Firefox 137, and we have seen that it makes revocation checking functional, reliable, and performant. We are hopeful that we can replicate our success in other, more constrained, environments as well.&lt;/p&gt;
  4054. &lt;h3&gt;Better privacy and performance&lt;/h3&gt;
  4055. &lt;p&gt;Prior to version 137, Firefox used the &lt;a href=&quot;https://en.wikipedia.org/wiki/Online_Certificate_Status_Protocol&quot;&gt;Online Certificate Status Protocol (OCSP)&lt;/a&gt; to ask authorities about revocation statuses in real time. Certificate authorities are &lt;a href=&quot;https://cabforum.org/2023/07/14/ballot-sc063v4-make-ocsp-optional-require-crls-and-incentivize-automation/&quot;&gt;no longer required&lt;/a&gt; to support OCSP, and some major certificate authorities have already &lt;a href=&quot;https://letsencrypt.org/2024/07/23/replacing-ocsp-with-crls/&quot;&gt;announced&lt;/a&gt; their intention to wind down their OCSP services. There are several reasons for this, but the foremost is that OCSP is a privacy leak. When a user asks an OCSP server about a certificate, they reveal to the server that they intend to visit a certain domain. Since OCSP requests are typically made over unencrypted HTTP, this information is also leaked to all on-path observers.&lt;/p&gt;
  4056. &lt;p&gt;Having gained confidence in the robustness, accuracy and performance of our CRLite implementation, we will be disabling OCSP for &lt;a href=&quot;https://en.wikipedia.org/wiki/Domain-validated_certificate&quot;&gt;domain validated certificates&lt;/a&gt; in Firefox 142. Sealing the OCSP privacy leak complements our ongoing efforts to encrypt everything on the internet by rolling out &lt;a href=&quot;https://support.mozilla.org/en-US/kb/https-first&quot;&gt;HTTPS-First&lt;/a&gt;, &lt;a href=&quot;https://support.mozilla.org/en-US/kb/firefox-dns-over-https&quot;&gt;DNS over HTTPS&lt;/a&gt;, and &lt;a href=&quot;https://blog.mozilla.org/en/firefox/encrypted-hello/&quot;&gt;Encrypted Client Hello&lt;/a&gt;.&lt;/p&gt;
  4057. &lt;p&gt;Disabling OCSP also has performance benefits: we have found that OCSP requests block the TLS handshake for 100 ms at the median. As we rolled out CRLite, we saw notable improvements in TLS handshake times.&lt;/p&gt;
  4058. &lt;p&gt;&lt;a href=&quot;https://hacks.mozilla.org/wp-content/uploads/2025/07/chart.svg&quot;&gt;&lt;img alt=&quot;A graph showing &amp;quot;Median TLS Handshake Time (ms)&amp;quot; and &amp;quot;Revocation mechanism usage&amp;quot; over time. As the percentage of revocation checks performed with CRLite increases from 0% to 80%, the median TLS handshake time decreases from 56.4 ms to 39.9 ms.&quot; class=&quot; wp-image-48232 aligncenter&quot; height=&quot;294&quot; src=&quot;https://hacks.mozilla.org/wp-content/uploads/2025/07/chart.svg&quot; width=&quot;475&quot; /&gt;&lt;/a&gt;&lt;/p&gt;
  4059. &lt;h3&gt;Bandwidth requirements of CRLite&lt;/h3&gt;
  4060. &lt;p&gt;Users with CRLite download an average of 300 kB of revocation data per day: a 4 MB snapshot every 45 days and a sequence of “delta updates” in-between. (The exact sizes of snapshots and delta updates fluctuate day by day. You can explore the real data on our &lt;a href=&quot;https://yardstick.mozilla.org/dashboard/snapshot/c1WZrxGkNxdm9oZp7xVvGUEFJCELfApN&quot;&gt;dashboard&lt;/a&gt;.)&lt;/p&gt;
  4061. &lt;p&gt;To get a sense for how compact CRLite artifacts are, let’s compare them with &lt;a href=&quot;https://en.wikipedia.org/wiki/Certificate_revocation_list&quot;&gt;Certificate Revocation Lists (CRLs)&lt;/a&gt;. A CRL is a list of serial numbers that each identify a revoked certificate from a single issuer. Certificate authorities in Mozilla’s root store have disclosed approximately three thousand active CRLs to the &lt;a href=&quot;https://www.ccadb.org/&quot;&gt;Common CA Database&lt;/a&gt;. In total, these three thousand CRLs are 300 MB in size, and the only way to keep a copy of them up-to-date is to redownload them regularly. CRLite encodes the same dynamic set of revoked certificates in 300 kB per day. In other words, CRLite is &lt;b&gt;one&lt;/b&gt; &lt;b&gt;thousand times more bandwidth-efficient&lt;/b&gt; than daily CRL downloads.&lt;/p&gt;
  4062. &lt;p&gt;Of course, no browser is performing daily downloads of all CRLs. For a more meaningful comparison, we can consider Chrome’s CRLSets. These are hand-picked sets of revocations that are delivered to Chrome users daily. Recent CRLSets weigh in at 600 kB and include about 1% of all revocations (thirty-five thousand of the four million total). Firefox’s CRLite implementation uses half the bandwidth, updates twice as frequently, and includes &lt;b&gt;all&lt;/b&gt; revocations.&lt;/p&gt;
  4063. &lt;p&gt;Including all revocations is essential for security as there is no reliable way today to distinguish security-critical revocations from administrative revocations. Roughly half of all revocations are made without a specified reason code, and some of these revocations are likely due to security concerns that the certificate’s owner did not wish to highlight. When reason codes &lt;i&gt;are&lt;/i&gt; used, they are often used in an ambiguous way that does not clearly map to security risk. In this environment, the only secure approach is to check all revocations, which is now possible with CRLite.&lt;/p&gt;
  4064. &lt;h3&gt;State-of-the-art blocklist technology&lt;/h3&gt;
  4065. &lt;p&gt;You may recall a &lt;a href=&quot;https://blog.mozilla.org/security/2020/01/09/crlite-part-1-all-web-pki-revocations-compressed/&quot;&gt;series&lt;/a&gt; &lt;a href=&quot;https://blog.mozilla.org/security/2020/01/09/crlite-part-2-end-to-end-design/&quot;&gt;of&lt;/a&gt; &lt;a href=&quot;https://blog.mozilla.org/security/2020/01/21/crlite-part-3-speeding-up-secure-browsing/&quot;&gt;blog&lt;/a&gt; &lt;a href=&quot;https://blog.mozilla.org/security/2020/12/01/crlite-part-4-infrastructure-design/&quot;&gt;posts&lt;/a&gt; on our experiments with CRLite back in 2020. We followed these experiments with successful deployments to Nightly, Beta, and 1% of Release users. But the bandwidth requirements for this early CRLite design turned out to be prohibitive.&lt;/p&gt;
  4066. &lt;p&gt;We solved our bandwidth issue by developing a novel data structure—the “Clubcard” set membership test. Where the &lt;a href=&quot;https://ieeexplore.ieee.org/document/7958597&quot;&gt;original&lt;/a&gt; CRLite design used a “multi-level cascades of Bloom filters”, Clubcard-based CRLite uses a “partitioned two-level cascade of &lt;a href=&quot;https://engineering.fb.com/2021/07/09/core-infra/ribbon-filter/&quot;&gt;Ribbon filters&lt;/a&gt;”. The “two-level cascade” idea was presented by Mike Hamburg at &lt;a href=&quot;https://youtu.be/Htms5rNy7B8?list=PLeeS-3Ml-rpovBDh6do693We_CP3KTnHU&amp;amp;t=2359&quot;&gt;RWC 2022&lt;/a&gt;, and “partitioning” is an innovation of our own that we presented in a paper at &lt;a href=&quot;https://research.mozilla.org/files/2025/04/clubcards_for_the_webpki.pdf&quot;&gt;IEEE S&amp;amp;P 2025&lt;/a&gt; and a talk at &lt;a href=&quot;https://www.youtube.com/watch?v=gnB76DQI1GE&amp;amp;t=19510s&quot;&gt;RWC 2025&lt;/a&gt;.&lt;/p&gt;
  4067. &lt;h3&gt;Future improvements&lt;/h3&gt;
  4068. &lt;p&gt;We are working on making CRLite even more bandwidth efficient. We are developing new Clubcard partitioning strategies that will compress mass revocation events more efficiently. We are also integrating support for the HTTP &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/Compression_dictionary_transport&quot;&gt;compression dictionary transport&lt;/a&gt;, which will further compress delta updates. And we have successfully advocated for shorter &lt;a href=&quot;https://github.com/cabforum/servercert/pull/553&quot;&gt;certificate validity periods&lt;/a&gt;, which will reduce the number of CRLite artifacts that need to encode any given revocation. With these enhancements, we expect the bandwidth requirements of CRLite to trend down over the coming years, even as the TLS ecosystem itself continues to grow.&lt;/p&gt;
  4069. &lt;p&gt;Our &lt;a href=&quot;https://github.com/mozilla/clubcard&quot;&gt;Clubcard&lt;/a&gt; blocklist library, our instantiation of &lt;a href=&quot;https://github.com/mozilla/clubcard-crlite&quot;&gt;Clubcards for CRLite&lt;/a&gt;, and our &lt;a href=&quot;http://github.com/mozilla/crlite&quot;&gt;CRLite&lt;/a&gt; backend are freely available for anyone to use. We hope that our success in building fast, private, and comprehensive revocation checking for Firefox will encourage other software vendors to adopt this technology.&lt;/p&gt;

  4078. <description>&lt;p&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;WebDriver is a remote control interface that enables introspection and control of user agents.&lt;/em&gt; &lt;em&gt;As such it&lt;/em&gt; &lt;em&gt;can&lt;/em&gt; &lt;em&gt;help developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the&lt;/em&gt;&lt;a href=&quot;https://www.w3.org/&quot;&gt;&lt;em&gt; W3C&lt;/em&gt;&lt;/a&gt;&lt;em&gt; and consists of two separate specifications:&lt;/em&gt;&lt;a href=&quot;https://w3c.github.io/webdriver/&quot;&gt;&lt;em&gt; WebDriver classic&lt;/em&gt;&lt;/a&gt;&lt;em&gt; (HTTP) and the new&lt;/em&gt;&lt;a href=&quot;https://w3c.github.io/webdriver-bidi/&quot;&gt;&lt;em&gt; WebDriver BiDi&lt;/em&gt;&lt;/a&gt;&lt;em&gt; (Bi-Directional).This newsletter gives an overview of the work we’ve done as part of the Firefox 142 release cycle&lt;/em&gt;.&lt;/p&gt;&lt;h3&gt;Contributions&lt;/h3&gt;&lt;p&gt;Firefox is an open source project, and we are always happy to receive external code contributions to our WebDriver implementation. We want to give special thanks to everyone who filed issues, bugs and submitted patches.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;
  4079.  
  4080.  
  4081.  
  4082. &lt;p&gt;In Firefox 142, Sabina (sabina.zaripova) &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1969898&quot;&gt;renamed &lt;code&gt;Proxy&lt;/code&gt; capability class to &lt;code&gt;ProxyConfiguration&lt;/code&gt;&lt;/a&gt; to avoid confusion with JavaScript Proxy.&lt;/p&gt;
  4083.  
  4084.  
  4085.  
  4086. &lt;p&gt;Also, biyul.dev &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1931528&quot;&gt;reverted a workaround for &lt;code&gt;asyncOpenTime=0&lt;/code&gt;&lt;/a&gt; in WebDriver BiDi and &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976504&quot;&gt;removed support for &lt;code&gt;localize_entity&lt;/code&gt; from the localization module&lt;/a&gt;.&lt;/p&gt;
  4087.  
  4088.

  4095.  
  4096.  
  4097.  
  4098. &lt;h4&gt;Removed: FTP proxy support from WebDriver capabilities&lt;/h4&gt;
  4099.  
  4100.  
  4101.  
  4102. &lt;p&gt;Support for &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972670&quot;&gt;setting FTP proxy with WebDriver capabilities&lt;/a&gt; was completely removed. &lt;/p&gt;
  4103.  
  4104.  
  4105.  
  4106. &lt;h4&gt;Updated: the expiry value of the cookies set via WebDriver BiDi and WebDriver classic (Marionette)&lt;/h4&gt;
  4107.  
  4108.  
  4109.  
  4110. &lt;p&gt;The expiry value of all the cookies set via WebDriver BiDi and WebDriver classic (Marionette) is &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974394&quot;&gt;limited now to 400 days&lt;/a&gt;.&lt;/p&gt;
  4111.

  4121.  
  4122. &lt;p&gt;Implemented &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1968952&quot;&gt;the new &lt;code&gt;emulation.setLocaleOverride&lt;/code&gt; command&lt;/a&gt; which allows clients to override a locale in JavaScript APIs. As all the other emulation commands, the locale override can be applied to the list of browsing contexts or user contexts IDs.&lt;/p&gt;
  4123.  
  4124.  
  4125.  
  4126. &lt;h4&gt;Updated: the &lt;code&gt;session.end&lt;/code&gt; command to resume the blocked requests&lt;/h4&gt;
  4127.  
  4128.  
  4129.  
  4130. &lt;p&gt;The &lt;code&gt;session.end&lt;/code&gt; command was updated to &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974426&quot;&gt;resume all requests which were blocked by network interceptions&lt;/a&gt;.&lt;/p&gt;
  4131.

  4139.  
  4140.  
  4141.  
  4142. &lt;h4&gt;Bug fixes&lt;/h4&gt;
  4143.  
  4144.  
  4145.  
  4146. &lt;ul&gt;
  4147. &lt;li&gt;&lt;code&gt;browsingContext.create&lt;/code&gt; command will not &lt;a href=&quot;https://bugzil.la/1841125&quot;&gt;fail anymore after a &lt;code&gt;browsingContext.print&lt;/code&gt; command was interrupted by closing a tab with the &lt;code&gt;browsingContext.close&lt;/code&gt; command&lt;/a&gt;.&lt;/li&gt;
  4148. &lt;/ul&gt;
  4149.  
  4150.

  4152. &lt;h3&gt;Marionette&lt;/h3&gt;
  4153.  
  4154.  
  4155.  
  4156. &lt;h4&gt;Updated: the &lt;code&gt;WebDriver:AddCookie&lt;/code&gt; command to throw an error for &lt;code&gt;sameSite=none&lt;/code&gt; and &lt;code&gt;secure=false&lt;/code&gt; attributes&lt;/h4&gt;
  4157.  
  4158.  
  4159.  
  4160. &lt;p&gt;From now on, &lt;a href=&quot;https://bugzil.la/1977205&quot;&gt;the &lt;code&gt;WebDriver:AddCookie&lt;/code&gt; command will throw an error when a target cookie has &lt;code&gt;sameSite=none&lt;/code&gt; and &lt;code&gt;secure=false&lt;/code&gt; attributes&lt;/a&gt;.&lt;/p&gt;
  4161.  
  4162.  
  4163.  
  4164. &lt;h4&gt;Removed: the dialog text value from the &lt;code&gt;unexpected alert open&lt;/code&gt; error message&lt;/h4&gt;
  4165.  
  4166.  
  4167.  
  4168. &lt;p&gt;&lt;a href=&quot;http://bugzil.la/1948236&quot;&gt;The &lt;code&gt;unexpected alert open&lt;/code&gt; error message will not contain anymore the dialog text value&lt;/a&gt;, since it is available via the &lt;code&gt;data&lt;/code&gt; field.&lt;/p&gt;</description>

  4173. <title>The Rust Programming Language Blog: Demoting x86_64-apple-darwin to Tier 2 with host tools</title>
  4174. <guid isPermaLink="true">https://blog.rust-lang.org/2025/08/19/demoting-x86-64-apple-darwin-to-tier-2-with-host-tools/</guid>
  4175. <link>https://blog.rust-lang.org/2025/08/19/demoting-x86-64-apple-darwin-to-tier-2-with-host-tools/</link>
  4176. <description>&lt;p&gt;In Rust 1.90.0, the target &lt;code&gt;x86_64-apple-darwin&lt;/code&gt; will be demoted to Tier 2 with host tools.
  4177. The standard library and the compiler will continue to be built and distributed,
  4178. but automated tests of these components are no longer guaranteed to be run.&lt;/p&gt;
  4179. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/08/19/demoting-x86-64-apple-darwin-to-tier-2-with-host-tools/#background&quot;&gt;&lt;/a&gt;
  4180. Background&lt;/h3&gt;
  4181. &lt;p&gt;Rust has supported macOS for a long time,
  4182. with some amount of support dating back to Rust 0.1 and likely before that.
  4183. During that time period,
  4184. Apple has changed CPU architectures from x86 to x86_64 and now to Apple silicon,
  4185. ultimately announcing the &lt;a href=&quot;https://en.wikipedia.org/wiki/Mac_transition_to_Apple_silicon#Timeline&quot;&gt;end of support&lt;/a&gt; for the x86_64 architecture.&lt;/p&gt;
  4186. &lt;p&gt;Similarly,
  4187. &lt;a href=&quot;https://github.blog/changelog/2025-07-11-upcoming-changes-to-macos-hosted-runners-macos-latest-migration-and-xcode-support-policy-updates/#macos-13-is-closing-down&quot;&gt;GitHub has announced&lt;/a&gt; that they will no longer provide free macOS x86_64 runners for public repositories.
  4188. The Rust Project uses these runners to execute automated tests for the &lt;code&gt;x86_64-apple-darwin&lt;/code&gt; target.
  4189. Since the &lt;a href=&quot;https://doc.rust-lang.org/stable/rustc/target-tier-policy.html&quot;&gt;target tier policy&lt;/a&gt; requires that Tier 1 platforms must run tests in CI,
  4190. the &lt;code&gt;x86_64-apple-darwin&lt;/code&gt; target must be demoted to Tier 2.&lt;/p&gt;
  4191. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/08/19/demoting-x86-64-apple-darwin-to-tier-2-with-host-tools/#what-changes&quot;&gt;&lt;/a&gt;
  4192. What changes?&lt;/h3&gt;
  4193. &lt;p&gt;Starting with Rust 1.90.0, &lt;code&gt;x86_64-apple-darwin&lt;/code&gt; will be Tier 2 with host tools.
  4194. For users,
  4195. nothing will change immediately;
  4196. builds of both the standard library and the compiler will still be distributed by the Rust Project for use via &lt;code&gt;rustup&lt;/code&gt; or alternative installation methods.&lt;/p&gt;
  4197. &lt;p&gt;Over time,
  4198. this target will likely accumulate bugs faster due to reduced testing.&lt;/p&gt;
  4199. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/08/19/demoting-x86-64-apple-darwin-to-tier-2-with-host-tools/#future&quot;&gt;&lt;/a&gt;
  4200. Future&lt;/h3&gt;
  4201. &lt;p&gt;If the &lt;code&gt;x86_64-apple-darwin&lt;/code&gt; target causes concrete problems,
  4202. it may be demoted further.
  4203. No plans for further demotion have been made yet.&lt;/p&gt;
  4204. &lt;p&gt;For more details on the motivation of the demotion, see &lt;a href=&quot;https://rust-lang.github.io/rfcs/3841-demote-x86_64-apple-darwin.html&quot;&gt;RFC 3841&lt;/a&gt;.&lt;/p&gt;</description>

  4209. <title>The Mozilla Blog: Firefox just got better for Chinese, Japanese and Korean speakers on Android</title>
  4210. <guid isPermaLink="false">https://blog.mozilla.org/?p=81368</guid>
  4211. <link>https://blog.mozilla.org/en/firefox/cjk-translation-on-android/</link>
  4212. <description>&lt;p&gt;When Firefox users ask for better translation support, we make it happen.&lt;/p&gt;
  4213.  
  4214.  
  4215.  
  4216. &lt;p&gt;Thanks to your feedback on &lt;a href=&quot;https://connect.mozilla.org/&quot;&gt;Mozilla Connect&lt;/a&gt;, Firefox now supports Chinese, Japanese, and Korean (often referred to as CJK) translation, both on desktop and Android. That means millions more people can browse and translate the web in their language, without sending their content to the cloud.&lt;/p&gt;
  4217.  
  4218.  
  4219.  
  4220. &lt;p&gt;“We saw so many requests on Mozilla Connect for CJK support,” said Marco Castelluccio, engineering manager. “It was clear. This is what users wanted us to prioritize.”&lt;/p&gt;
  4221.  
  4222.  
  4223.  
  4224. &lt;h3&gt;&lt;strong&gt;Translation without tracking&lt;/strong&gt;&lt;/h3&gt;
  4225.  
  4226.  
  4227.  
  4228. &lt;p&gt;Unlike other browsers that send your content to the cloud for translation, Firefox handles everything locally on your device. That means more privacy, more control, and it even works offline once the language model is downloaded.&lt;/p&gt;
  4229.  
  4230.  
  4231.  
  4232. &lt;p&gt;“Firefox automatically downloads the model once,” explained Erik Nordin, software engineer. “After that, translations happen on your phone. The content never leaves your device, and Firefox does not track what you translate.”&lt;/p&gt;
  4233.  
  4234.  
  4235.  
  4236. &lt;p&gt;On-device translation requires efficiency. Mobile devices have limited memory and processing power, so the team developed smarter translation algorithms that prioritize the content you’re actually reading. &lt;/p&gt;
  4237.  
  4238.  
  4239.  
  4240. &lt;p&gt;“If you’re only reading the top of a long page, Firefox won’t waste time and energy translating the whole thing,” Erik said.&lt;/p&gt;
  4241.  
  4242.  
  4243.  
  4244. &lt;p&gt;This approach is part of Mozilla’s broader mission to build technologies that respect your privacy by design. No compromises.&lt;/p&gt;
  4245.  
  4246.  
  4247.  
  4248. &lt;h3&gt;&lt;strong&gt;We took our time to get it right &lt;/strong&gt;&lt;/h3&gt;
  4249.  
  4250.  
  4251.  
  4252. &lt;p&gt;Chinese, Japanese and Korean use characters, grammar and sentence structures that vary significantly from Latin-based languages. &lt;/p&gt;
  4253.  
  4254.  
  4255.  
  4256. &lt;p&gt;“Our earlier translation algorithms were not able to handle writing scripts that do not insert a space character between sentences,” Erik said. “CJK languages required us to rethink both the architecture and how we algorithmically segment text.”&lt;/p&gt;
  4257.  
  4258.  
  4259.  
  4260. &lt;p&gt;And there’s simply less open-source data available to train CJK translation models compared to European languages.&lt;/p&gt;
  4261.  
  4262.  
  4263.  
  4264. &lt;p&gt;“Our models are trained completely on publicly available data,” said Marco. “That’s important for transparency, but it also means it’s harder to find enough good-quality examples for CJK languages.”&lt;/p&gt;
  4265.  
  4266.  
  4267.  
  4268. &lt;p&gt;To make things even trickier, Firefox translation works locally. That means the models had to be smart enough to handle these complex languages and lightweight enough to run on mobile phones.&lt;/p&gt;
  4269.  
  4270.  
  4271.  
  4272. &lt;p&gt;“We had to rework our algorithms to make translation feel faster and more responsive,” Erik said. “Now, Firefox prioritizes the part of the page you’re looking at instead of translating everything at once.”&lt;/p&gt;
  4273.  
  4274.  
  4275.  
  4276. &lt;p&gt;To overcome these challenges, the team upgraded their machine learning models, overhauled the sentence segmentation pipeline, and optimized performance to ensure a smooth experience — especially on older and low-end Android devices.&lt;/p&gt;
  4277.  
  4278.  
  4279.  
  4280. &lt;h3&gt;&lt;strong&gt;What stuffed mushrooms taught us about machine learning&lt;/strong&gt;&lt;/h3&gt;
  4281.  
  4282.  
  4283.  
  4284. &lt;p&gt;Mozilla engineers don’t speak every language we support. That’s why we leaned on the community and our collegues to help test CJK translation before launch. Volunteers tried out early versions in Firefox Nightly and flagged issues.&lt;/p&gt;
  4285.  
  4286.  
  4287.  
  4288. &lt;p&gt;“That feedback was gold,” Erik said. “It helped us tweak the models and make sure the translations made sense in real-world use.”&lt;/p&gt;
  4289.  
  4290.  
  4291.  
  4292. &lt;p&gt;And it was essential. Neither Marco nor Erik speaks any of the CJK languages. (Marco speaks Italian and English, and Erik is fluent in English with conversational Spanish.) To validate accuracy, they relied on community testers, Mozillians fluent in Chinese, Japanese or Korean, and members of MozAPI, Mozilla’s resource group for Asian and Pacific Islander employees.&lt;/p&gt;
  4293.  
  4294.  
  4295.  
  4296. &lt;p&gt;“One tester pointed out a restaurant menu item translating ‘stuffed mushrooms’ as a plush toy,” Erik laughed. “It was a great reminder of how nuanced language can be.”&lt;/p&gt;
  4297.  
  4298.  
  4299.  
  4300. &lt;p&gt;“We can measure accuracy with automated tools,” Erik added, “but there’s no substitute for a native speaker saying, ‘Yeah, that sounds right,’ or ‘Actually, this reads a little strange.’”&lt;/p&gt;
  4301.  
  4302.  
  4303.  
  4304. &lt;h3&gt;&lt;strong&gt;Try Chinese, Japanese and Korean translation now built into Firefox&lt;/strong&gt;&lt;/h3&gt;
  4305.  
  4306.  
  4307.  
  4308. &lt;p&gt;CJK translation is already making a difference. Since launching support on desktop, Firefox has more than doubled active translation users in Asia. With Android support now rolling out in Firefox, even more people can experience the web in their language, safely and privately.&lt;/p&gt;
  4309.  
  4310.  
  4311.  
  4312. &lt;p&gt;Update to the latest version of Firefox for Android or desktop to start using CJK translation. Then, tap the translate icon when you visit a page in Chinese, Japanese or Korean. Firefox will do the rest, right on your device. For a list of all the translations available on Firefox, visit &lt;a href=&quot;https://www.firefox.com/en-US/features/translate/&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;
  4313.  
  4314.  
  4315.  
  4316. &lt;a class=&quot;ft-c-inline-cta&quot; href=&quot;https://apps.apple.com/us/app/firefox-private-web-browser/id989804926&quot;&gt;

  4327. <title>Mozilla Addons Blog: Introducing the Firefox Extension Developer Awards Program</title>
  4328. <guid isPermaLink="false">https://blog.mozilla.org/addons/?p=9253</guid>
  4329. <link>https://blog.mozilla.org/addons/2025/08/15/introducing-the-firefox-extension-developer-awards-program/</link>
  4330. <description>&lt;p&gt;At Firefox, we deeply value the incredible contributions of our add-ons developer community. Your creativity and innovation are instrumental in making Firefox a more personalized and powerful browsing experience for millions of users worldwide.&lt;/p&gt;
  4331. &lt;p&gt;Today, we’re thrilled to announce a new program designed to recognize and celebrate the developers who have made an outstanding impact on our ecosystem: the Firefox Extension Developer Awards Program!&lt;/p&gt;
  4332. &lt;p&gt;Extensions play a vital role in enhancing the Firefox user experience. Almost 40% of Firefox users have installed at least one add-on, making it clear that our thriving ecosystem, supported by 10,000 active developers, is an essential component of the Firefox experience. While all developers contribute to the diversity and depth of the ecosystem, there are a number of popular extensions responsible for significant positive impact. This program aims to acknowledge and reward these developers for their significant contributions.&lt;/p&gt;
  4333. &lt;h3&gt;The Awards: A Token of Our Appreciation&lt;/h3&gt;
  4334. &lt;p&gt;Inspired by programs like YouTube’s creator awards, we’ve partnered with &lt;a href=&quot;https://www.aparatdesign.com/bios&quot;&gt;Aparat Design&lt;/a&gt;, to create a unique Mozilla inspired trophy for eligible award recipients.&lt;a href=&quot;https://blog.mozilla.org/addons/files/2025/08/PXL_20250819_175111542.MP_-scaled.jpg&quot;&gt;&lt;img alt=&quot;Firefox add-on developer award trophy&quot; class=&quot;size-medium wp-image-9257 aligncenter&quot; height=&quot;772&quot; src=&quot;https://blog.mozilla.org/addons/files/2025/08/PXL_20250819_175111542.MP_-580x772.jpg&quot; width=&quot;580&quot; /&gt;&lt;/a&gt;The award will be engraved with the name of the extension and finished with a different color based on the milestone it has achieved. This is a unique and exclusive opportunity available only to Firefox extension developers.&lt;/p&gt;
  4335. &lt;table&gt;
  4336. &lt;thead&gt;
  4337. &lt;tr&gt;
  4338. &lt;th&gt;Milestone Tier&lt;/th&gt;
  4339. &lt;th&gt;Average Daily Active Users&lt;/th&gt;
  4340. &lt;/tr&gt;
  4341. &lt;/thead&gt;
  4342. &lt;tbody&gt;
  4343. &lt;tr&gt;
  4344. &lt;td&gt;Platinum&lt;/td&gt;
  4345. &lt;td&gt;Over 10 million&lt;/td&gt;
  4346. &lt;/tr&gt;
  4347. &lt;tr&gt;
  4348. &lt;td&gt;Gold&lt;/td&gt;
  4349. &lt;td&gt;Over 5 million&lt;/td&gt;
  4350. &lt;/tr&gt;
  4351. &lt;tr&gt;
  4352. &lt;td&gt;Silver&lt;/td&gt;
  4353. &lt;td&gt;Over 1 million&lt;/td&gt;
  4354. &lt;/tr&gt;
  4355. &lt;tr&gt;
  4356. &lt;td&gt;Bronze&lt;/td&gt;
  4357. &lt;td&gt;Over 500,000&lt;/td&gt;
  4358. &lt;/tr&gt;
  4359. &lt;/tbody&gt;
  4360. &lt;/table&gt;
  4361. &lt;h3&gt;How the program works&lt;/h3&gt;
  4362. &lt;p&gt;All Firefox extensions listed on AMO (&lt;a href=&quot;https://addons.mozilla.org&quot;&gt;addons.mozilla.org&lt;/a&gt;) are eligible for an award, so long as requisite user thresholds are reached and the content is compliant with &lt;a href=&quot;https://extensionworkshop.com/documentation/publish/add-on-policies/&quot;&gt;Add-on Policies&lt;/a&gt;.&lt;/p&gt;
  4363. &lt;p&gt;Each quarter, our team will identify new extensions that meet the award criteria and maintain a good standing with Firefox.&lt;/p&gt;
  4364. &lt;p&gt;We’re incredibly excited about the Firefox Extension Developer Awards Program and look forward to celebrating your achievements! Stay tuned to this very blog for the announcement of our inaugural round of award recipients.&lt;/p&gt;

  4370. <title>Mozilla Privacy Blog: Is Germany on the Brink of Banning Ad Blockers? User Freedom, Privacy, and Security Is At Risk.</title>
  4371. <guid isPermaLink="false">https://blog.mozilla.org/netpolicy/?p=2494</guid>
  4372. <link>https://blog.mozilla.org/netpolicy/2025/08/14/is-germany-on-the-brink-of-banning-ad-blockers-user-freedom-privacy-and-security-is-at-risk/</link>
  4373. <description>&lt;p&gt;Across the internet, users rely on browsers and extensions to shape how they experience the web: to protect their privacy, improve accessibility, block harmful or intrusive content, and take control over what they see. But a recent ruling from Germany’s Federal Supreme Court risks turning one of these essential tools, the ad blocker, into a copyright liability — and in doing so, threatens the broader principle of user choice online.&lt;/p&gt;
  4374. &lt;p&gt;Imagine you are watching television and you go to the kitchen for a snack during an ad break. Or you press the fast-forward button to skip some ads while listening to a podcast. Or perhaps you get a newspaper delivered to your house, and you see that it includes a special section made up of &lt;a href=&quot;https://www.npr.org/2025/05/20/nx-s1-5405022/fake-summer-reading-list-ai&quot;&gt;hallucinated AI content&lt;/a&gt;, so you drop the inset into the trash before taking the rest of the paper inside. Were these acts of copyright infringement? Of course not. But if you do something like this with a browser extension, &lt;a href=&quot;https://www.heise.de/en/news/Copyright-Springer-vs-Adblock-Plus-enters-another-round-10505898.html&quot;&gt;a recent decision from the German Federal Supreme Court&lt;/a&gt; suggests that maybe you did infringe copyright. This misguided logic risks user freedom, privacy, and security.&lt;/p&gt;
  4375. &lt;p&gt;There are many reasons, in addition to ad blocking, that users might want their browser or a browser extension to alter a webpage. These include changes to &lt;a href=&quot;https://support.mozilla.org/en-US/kb/accessibility-features-firefox&quot;&gt;improve&lt;/a&gt; &lt;a href=&quot;https://www.boia.org/blog/how-browser-reader-modes-improve-the-experiences-of-people-with-disabilities&quot;&gt;accessibility&lt;/a&gt;, to &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/addon/wave-accessibility-tool/&quot;&gt;evaluate accessibility&lt;/a&gt;, or to &lt;a href=&quot;https://support.mozilla.org/en-US/kb/firefox-privacy-and-security-features&quot;&gt;protect&lt;/a&gt; &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/tag/privacy/&quot;&gt;privacy&lt;/a&gt;. Indeed, the risks of browsing range from phishing, to malicious code execution, to invasive tracking, to fingerprinting, to more mundane harms like inefficient website elements that waste processing resources. Users should be equipped with browsers and browser extensions that give them both protection and choice in the face of these risks. &lt;b&gt;A browser that inflexibly ran any code served to the user would be an extraordinarily dangerous piece of software. &lt;/b&gt;Ad blockers are just one piece of this puzzle, but they are an important way that users &lt;a href=&quot;https://addons.mozilla.org/blog/whats-the-best-ad-blocker-for-you/&quot;&gt;can customize their experience&lt;/a&gt; and lower &lt;a href=&quot;https://www.vice.com/en/article/the-nsa-and-cia-use-ad-blockers-because-online-advertising-is-so-dangerous/&quot;&gt;risks to their security&lt;/a&gt; and privacy.&lt;/p&gt;
  4376. &lt;p&gt;The recent court ruling is the latest development in a legal battle between publisher Axel Springer and Eyeo (the maker of Adblock Plus) that has been winding its way around the German legal system for more than a decade. The litigation has included both competition and copyright claims. Until now Eyeo has largely prevailed and the legality of ad blockers has been upheld. Most significantly, in 2022, the Hamburg appeal court &lt;a href=&quot;https://dejure.org/dienste/vernetzung/rechtsprechung?Gericht=LG%20Hamburg&amp;amp;Datum=14.01.2022&amp;amp;Aktenzeichen=308%20O%20130/19&quot;&gt;ruled&lt;/a&gt; that Adblock Plus did not infringe the copyright of websites but rather was merely facilitating a choice by users about &lt;i&gt;how&lt;/i&gt; they wished their browser to render the page.&lt;/p&gt;
  4377. &lt;p&gt;Unfortunately, on July 31, the German Federal Supreme Court partially overturned the decision of the Hamburg court and remanded the case for further proceedings. The BGH (as the Federal Supreme Court is known) &lt;a href=&quot;https://www.tcilaw.de/en/ad%E2%80%91blockers-infringing-cheat-software-not/&quot;&gt;called for a new hearing&lt;/a&gt; so that the Hamburg court can provide more detail regarding which part of the website (such as bytecode or object code) is altered by ad blockers, whether this code is protected by copyright, and under what conditions the interference might be justified.&lt;/p&gt;
  4378. &lt;p&gt;The full impact of this latest development is still unclear. The BGH will issue a more detailed written ruling explaining its decision. Meanwhile, the case has now returned to the lower court for additional fact-finding. It could be a couple more years until we have a clear answer. We hope that the courts ultimately reach the same sensible conclusion and allow users to install ad blockers.&lt;/p&gt;
  4379. &lt;p&gt;We sincerely hope that Germany does not become the second jurisdiction (&lt;a href=&quot;https://scholar.google.com/citations?view_op=view_citation&amp;amp;hl=zh-CN&amp;amp;user=8VqyTHcAAAAJ&amp;amp;citation_for_view=8VqyTHcAAAAJ:YsMSGLbcyi4C&quot;&gt;after China&lt;/a&gt;) to ban ad blockers. This will significantly limit users’ ability to control their online environment and potentially open the door to similar restrictions elsewhere. Such a precedent could embolden legal challenges against other extensions that protect privacy, enhance accessibility, or improve security. Over time, this could deter innovation in these areas, pressure browser vendors to limit extension functionality, and shift the internet away from its &lt;a href=&quot;https://www.mozilla.org/en-US/about/webvision/full/#agency&quot;&gt;open, user-driven nature&lt;/a&gt; toward one with reduced flexibility, innovation, and control for users.&lt;/p&gt;

  4385. <title>Mozilla Thunderbird: Thunderbird Monthly Development Digest – July 2025</title>
  4386. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3725</guid>
  4387. <link>https://blog.thunderbird.net/2025/08/thunderbird-monthly-development-digest-july-2025/</link>
  4388. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/blog-banner-developer-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  4389. &lt;p&gt;Hello again from the Thunderbird development team! As the northern hemisphere rolls into late summer and the last of the vacation photos trickle into our chat channels, the team is balancing maintenance sprints with ongoing feature-related projects. Whether you’re basking in the sun or bundled up for a southern winter, we’ve got plenty to share about what’s been happening behind the scenes, and what’s coming next.&lt;/p&gt;
  4390.  
  4391.  
  4392.  
  4393. &lt;h4&gt;&lt;strong&gt;Exchange support&lt;/strong&gt;&lt;/h4&gt;
  4394.  
  4395.  
  4396.  
  4397. &lt;p&gt;It’s been a whirlwind of progress since our last update and with the expanded team collaborating regularly. It has felt like we’ve hit our stride and the finish line is in sight. Driven by a dramatic increase in automated test coverage, the team has been able to detect gaps and edge cases to help improve many areas of the existing code, and close out a good number of bugs.&lt;/p&gt;
  4398.  
  4399.  
  4400.  
  4401. &lt;p&gt;As we ready the feature set for wider release, we’ve taken the opportunity to revisit the backlog and feel confident enough with our pace to prioritize a few features and address them sooner than originally planned.&lt;/p&gt;
  4402.  
  4403.  
  4404.  
  4405. &lt;p&gt;The July roadmap worked out very well, with our planned features landing and a number of bonus items also complete:&lt;/p&gt;
  4406.  
  4407.  
  4408.  
  4409. &lt;ul&gt;
  4410. &lt;li&gt;Automated test coverage&lt;/li&gt;
  4411.  
  4412.  
  4413.  
  4414. &lt;li&gt;Message filtering&lt;/li&gt;
  4415.  
  4416.  
  4417.  
  4418. &lt;li&gt;Setting as Junk/Not Junk&lt;/li&gt;
  4419.  
  4420.  
  4421.  
  4422. &lt;li&gt;Remote content display/blocking&lt;/li&gt;
  4423.  
  4424.  
  4425.  
  4426. &lt;li&gt;Callback modernization/simplification&lt;/li&gt;
  4427.  
  4428.  
  4429.  
  4430. &lt;li&gt;Propagation of certificate and connection errors&lt;/li&gt;
  4431.  
  4432.  
  4433.  
  4434. &lt;li&gt;Archiving&lt;/li&gt;
  4435.  
  4436.  
  4437.  
  4438. &lt;li&gt;Saving Drafts&lt;/li&gt;
  4439.  
  4440.  
  4441.  
  4442. &lt;li&gt;Back-off handling&lt;/li&gt;
  4443. &lt;/ul&gt;
  4444.  
  4445.  
  4446.  
  4447. &lt;p&gt;Items we’ve prioritized for the next few weeks are:&lt;/p&gt;
  4448.  
  4449.  
  4450.  
  4451. &lt;ul&gt;
  4452. &lt;li&gt;Undo/Redo operations for move/copy/delete&lt;/li&gt;
  4453.  
  4454.  
  4455.  
  4456. &lt;li&gt;Status Bar feedback messaging&lt;/li&gt;
  4457.  
  4458.  
  4459.  
  4460. &lt;li&gt;Bug backlog&lt;/li&gt;
  4461. &lt;/ul&gt;
  4462.  
  4463.  
  4464.  
  4465. &lt;p&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1847846&quot;&gt;&lt;u&gt;Keep track of feature delivery here.&lt;/u&gt;&lt;/a&gt;&lt;/p&gt;
  4466.  
  4467.  
  4468.  
  4469. &lt;h4&gt;&lt;strong&gt;Account Hub&lt;/strong&gt;&lt;/h4&gt;
  4470.  
  4471.  
  4472.  
  4473. &lt;p&gt;A few users have reported issues following end user adoption of this feature, so we’re addressing these while finalizing Account Hub for Address Book items, such as LDAP configuration. The team is also planning the implementation of telemetry which will help us determine areas for improvement in this important part of the application.&lt;/p&gt;
  4474.  
  4475.  
  4476.  
  4477. &lt;h4&gt;&lt;strong&gt;Global Message Database [Panorama]&lt;/strong&gt;&lt;/h4&gt;
  4478.  
  4479.  
  4480.  
  4481. &lt;p&gt;The team has been focused on Exchange implementation and larger scale refactoring which isn’t directly tied to this project, so no updates to note here. The next time I write will be during a work week that has been dedicated to “Conversation View”, which is one of the key drivers for our database overhaul. Stay tuned for updates and decisions coming out of that collaboration.&lt;/p&gt;
  4482.  
  4483.  
  4484.  
  4485. &lt;p&gt;To follow their progress, take a look at the &lt;a href=&quot;https://bugzilla.mozilla.org/showdependencytree.cgi?id=1572000&amp;amp;hide_resolved=1&quot;&gt;&lt;u&gt;meta bug dependency tree&lt;/u&gt;&lt;/a&gt;. The team also maintains documentation in Sourcedocs which are visible &lt;a href=&quot;https://source-docs.thunderbird.net/en/latest/panorama/index.html&quot;&gt;&lt;u&gt;here&lt;/u&gt;&lt;/a&gt;.&lt;/p&gt;
  4486.  
  4487.  
  4488.  
  4489. &lt;h4&gt;&lt;strong&gt;Maintenance, Recent Features and Fixes&lt;/strong&gt;&lt;/h4&gt;
  4490.  
  4491.  
  4492.  
  4493. &lt;p&gt;August is set aside as a focus for maintenance, with half our team dedicated to inglorious yet important items from our roadmap. In addition to these items, we’ve had help from the development community to deliver a variety of improvements over the past month:&lt;/p&gt;
  4494.  
  4495.  
  4496.  
  4497. &lt;ul&gt;
  4498. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1980800&quot;&gt;&lt;u&gt;Various&lt;/u&gt;&lt;/a&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1979983&quot;&gt;&lt;u&gt;newsgroup&lt;/u&gt;&lt;/a&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1979618&quot;&gt;&lt;u&gt;fixes&lt;/u&gt;&lt;/a&gt;&lt;/li&gt;
  4499.  
  4500.  
  4501.  
  4502. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/buglist.cgi?bug_status=UNCONFIRMED&amp;amp;bug_status=NEW&amp;amp;bug_status=ASSIGNED&amp;amp;bug_status=REOPENED&amp;amp;bug_status=RESOLVED&amp;amp;bug_status=VERIFIED&amp;amp;bug_status=CLOSED&amp;amp;short_desc=port%20bug&amp;amp;chfield=resolution&amp;amp;query_format=advanced&amp;amp;email1=richard.marti%40gmail.com&amp;amp;list_id=17661032&amp;amp;emailtype1=substring&amp;amp;chfieldvalue=FIXED&amp;amp;resolution=FIXED&amp;amp;emailassigned_to1=1&amp;amp;short_desc_type=allwordssubstr&amp;amp;chfieldto=2025-08-08&amp;amp;chfieldfrom=2025-07-01&amp;amp;classification=Client%20Software&amp;amp;classification=Developer%20Infrastructure&amp;amp;classification=Components&amp;amp;classification=Server%20Software&amp;amp;classification=Other&quot;&gt;&lt;u&gt;Another pile of port bugs&lt;/u&gt;&lt;/a&gt; to adapt Thunderbird to upstream changes&lt;/li&gt;
  4503.

  4537. <title>The Mozilla Blog: Driving towards a double bottom line, through participation and choice</title>
  4538. <guid isPermaLink="false">https://blog.mozilla.org/?p=81445</guid>
  4539. <link>https://blog.mozilla.org/en/mozilla/responsible-tech/</link>
  4540. <description>&lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;The Mozilla logo in green on a black background&quot; class=&quot;wp-image-78766&quot; height=&quot;576&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/03/Mozilla-Blog-Thumbnail@2x-1024x576.png&quot; width=&quot;1024&quot; /&gt;&lt;/figure&gt;
  4541.  
  4542.  
  4543.  
  4544. &lt;p&gt;As global political landscapes shift, mission-driven organizations face a critical challenge: creating resilient models that deliver meaningful social impact &lt;em&gt;and&lt;/em&gt; financial stability.&lt;/p&gt;
  4545.  
  4546.  
  4547.  
  4548. &lt;p&gt;For over 25 years, Mozilla has worked to strike this balance across diverse political and economic climates. While Mozilla’s structure is unique — a non-profit Foundation as the sole shareholder of multiple commercial subsidiaries — our approach to social impact doesn’t only rely on our unique governance model. It also requires a portfolio-wide commitment to using technology development, industry influence and consumer power as a way to build meaningful alternatives.&lt;/p&gt;
  4549.  
  4550.  
  4551.  
  4552. &lt;p&gt;From 2016 to 2024, we ran several advocacy programs focused on the consumer power piece of this equation. This post reflects back on this work with the hope that leaders of other social impact organizations can learn from the path that Mozilla has traveled. We focus on three concrete ways to create change by focusing on mobilizing consumer demand — for technology they love and trust, and for social impact.&lt;/p&gt;
  4553.  
  4554.  
  4555.  
  4556. &lt;h3&gt;&lt;strong&gt;Mozilla’s advocacy history  &lt;/strong&gt;&lt;/h3&gt;
  4557.  
  4558.  
  4559.  
  4560. &lt;p&gt;Mozilla’s advocacy philosophy centers on creating change by building technology with public support and participation. Mozilla Co-founder Mitchell Baker identified Mozilla’s core strength as “advocacy through building technology, using an architecture of participation.”&lt;/p&gt;
  4561.  
  4562.  
  4563.  
  4564. &lt;p&gt;In the early 2000s, Mozilla channeled public frustration over Microsoft’s growing monopolization of computing and the web, sparking both a consumer backlash and a cadre of open source projects aimed at creating alternatives.&lt;/p&gt;
  4565.  
  4566.  
  4567.  
  4568. &lt;p&gt;These projects — and the responsible tech companies that many of them spawned — showed that you could push technology in a better direction by creating alternatives. Starting in 2016, we decided that Mozilla should not only continue to build alternatives but also that we should expand our efforts to include advocacy programs that invited the public to participate in this future, both in helping to define what alternatives should be built and to push on tech companies to do better. &lt;/p&gt;
  4569.  
  4570.  
  4571.  
  4572. &lt;p&gt;This included three key strategies to increase and meet consumer demand for “trustworthy AI” and privacy-centric products.  &lt;/p&gt;
  4573.  
  4574.  
  4575.  
  4576. &lt;h4&gt;Empowering consumers &lt;/h4&gt;
  4577.  
  4578.  
  4579.  
  4580. &lt;p&gt;Consumer power grows when and where we cultivate it. Where are consumer sentiment and commercial offerings out of sync? These intersections present a rich opportunity for mission-based organizations and companies to stand out and make a difference. &lt;/p&gt;
  4581.  
  4582.  
  4583.  
  4584. &lt;p&gt;Beginning in 2017, our Mozilla team noted a large gap between consumer attitudes about privacy and market share for privacy-preserving products in the U.S. and elsewhere. When we asked our global community for insight, the same questions surfaced again and again: “Do products that respect consumer privacy exist?” and, “How can I tell if a product I own (or want to buy) respects my privacy?” Indeed, to our surprise, we couldn’t find a comprehensive, accessible consumer guide on privacy-preserving tech! &lt;/p&gt;
  4585.  
  4586.  
  4587.  
  4588. &lt;p&gt;We set out to address this gap by launching Mozilla’s &lt;a href=&quot;https://www.mozillafoundation.org/en/privacynotincluded/&quot;&gt;&lt;em&gt;Privacy Not Included&lt;/em&gt;&lt;/a&gt; initiative. From 2017 to 2024, the &lt;em&gt;Privacy Not Included &lt;/em&gt;team researched and evaluated the privacy and security practices of over 2,000 consumer technology products, platforms and apps. Their product reviews balanced accessibility and reliability, which translated into detailed reviews with a strong dose of snark and humor. We performed the research everyone knows they &lt;em&gt;should&lt;/em&gt; do before using a product, but never does.&lt;/p&gt;
  4589.  
  4590.  
  4591.  
  4592. &lt;p&gt;From a public engagement and empowerment perspective, &lt;em&gt;Privacy Not Included&lt;/em&gt; was an instant success. It quickly reached millions of consumers globally through Mozilla platforms, social and traditional media as well as organic sharing. The guide’s unique content drew more than a million unique visitors to Mozilla’s website each year, while the project garnered more than 7,000 local, national and global media stories to date. &lt;em&gt;Privacy Not Included&lt;/em&gt; also sparked ongoing, year-round engagement with our community as thousands of readers nominated products for review and thousands more rated products using our custom “creep-o-meter” rating system. &lt;/p&gt;
  4593.  
  4594.  
  4595.  
  4596. &lt;p&gt;As the reach and visibility of &lt;em&gt;Privacy Not Included &lt;/em&gt;grew&lt;em&gt;, &lt;/em&gt;the project further empowered consumers by providing a platform to pressure companies to improve the privacy and security of products already in use. It was a natural evolution and connected easily with our other advocacy capabilities but, honestly, it wasn’t something we planned ahead of time. Connecting our research and campaigns functions, the Mozilla Foundation regularly issued action alerts calling on companies with the lowest rated products to improve their products and policies right away. In response to our Privacy Not Included campaigns, companies reach out to us to complain, inquire, ask questions, and ultimately make significant improvements. &lt;/p&gt;
  4597.  
  4598.  
  4599.  
  4600. &lt;p&gt;As proof of the impact: several large tech companies changed their product release schedule to ensure our team would review their updated products in the next issue of &lt;em&gt;Privacy Not Included&lt;/em&gt;.  &lt;/p&gt;
  4601.  
  4602.  
  4603.  
  4604. &lt;p&gt;&lt;em&gt;Privacy Not Included&lt;/em&gt;’s research and public campaigns to date have sparked more than 150 improvements to consumer technology products used by billions. Among the most far-reaching changes resulted from our 2023 investigation into the data collection and data sharing by car manufacturers. Our researchers uncovered data collection and sharing by all 25 major car manufacturers, with many collecting vast amounts of personal information, including sensitive data like genetic information and sexual activity, and sharing it with third parties. &lt;/p&gt;
  4605.  
  4606.  
  4607.  
  4608. &lt;p&gt;The report sparked widespread public outrage and media attention (over 900 press stories), and prompted further investigation by Senator Markey and the Federal Trade Commission (FTC). In response, the car manufacturer’s association (The Alliance for Automotive Innovation) announced their support for federal data privacy legislation for the first time. Additionally, Toyota, Lexus and GM pledge to stop selling driver data to data brokers and to expand driver’s ability to delete data. (There’s now &lt;a href=&quot;https://www.ksn.com/wp-content/uploads/sites/13/2025/07/Court-Filing.pdf&quot;&gt;a court case pending in Nebraska &lt;/a&gt;based on this research) &lt;/p&gt;
  4609.  
  4610.  
  4611.  
  4612. &lt;p&gt;Both by design and by accident, &lt;em&gt;Privacy Not Included&lt;/em&gt; expanded its impact well beyond providing consumers with reliable, accessible information about the privacy (or not) in consumer technology products. Its research prompted meaningful, voluntary actions by companies unaccustomed to being investigated and called out for invasive features and practices. Today, “responsible technology” is increasingly the default expectation by consumers and a bar companies seek to meet.  &lt;/p&gt;
  4613.  
  4614.  
  4615.  
  4616. &lt;h4&gt;&lt;strong&gt;Shaping products &lt;/strong&gt;&lt;/h4&gt;
  4617.  
  4618.  
  4619.  
  4620. &lt;p&gt;Responsible products aren’t always “born.” More commonly, they evolve through incremental improvements including changes driven by consumer demand and relevant regulations. Trusted organizations can effectively &lt;em&gt;surface&lt;/em&gt;, &lt;em&gt;translate&lt;/em&gt; and &lt;em&gt;mobilize&lt;/em&gt; public opinion to spark actionable changes by companies and policymakers.&lt;/p&gt;
  4621.  
  4622.  
  4623.  
  4624. &lt;p&gt;Mozilla tackled each of these functions when we created a platform for consumers to share their experiences with YouTube’s recommendation algorithm and participate in research to demonstrate what changes were needed to improve YouTube’s safety.  &lt;/p&gt;
  4625.  
  4626.  
  4627.  
  4628. &lt;p&gt;Several years after&lt;a href=&quot;https://www.npr.org/2018/04/11/601323233/6-facts-we-know-about-fake-news-in-the-2016-election&quot;&gt; the focus on social media’s role &lt;/a&gt;in the spread of misinformation during the 2016 US election, questions started to emerge about the impact of YouTube’s recommendation algorithm in viral misinformation. At the time, no significant independent research had been conducted to show whether – or how – misinformation was spreading on the platform. To learn more, we asked Mozilla supporters to tell us about their experience with video recommendations on YouTube and we received over &lt;a href=&quot;https://www.bbc.com/news/technology-50045919&quot;&gt;2,000 stories&lt;/a&gt; that highlighted specific instances in which people were recommended violent content or misinformation that did not relate to their previous viewing history or search.  &lt;/p&gt;
  4629.  
  4630.  
  4631.  
  4632. &lt;p&gt;These powerful stories compelled us to further examine YouTube’s recommendation algorithm using research methods that would validate our concerns to spark action by Google and policymakers. In 2020, we launched “YouTube Regrets,” a global &lt;a href=&quot;https://www.mozillafoundation.org/en/youtube/findings/&quot;&gt;crowdsourced research&lt;/a&gt; study analyzing data from more than 37,000 across 190 countries. Based on our extensive analysis of the data submitted from user sessions, we validated the platform’s practice of recommending extreme content users had not requested. Our findings also highlighted striking differences between the volume and type of content recommended to users in the U.S. and other countries. &lt;/p&gt;
  4633.  
  4634.  
  4635.  
  4636. &lt;p&gt;The YouTube Regrets research and crowdsourced methodology brought to life people’s real-life experiences and gained widespread media attention, followed by extensive interest among global policymakers. Mozilla held extensive briefings with policymakers, including the EU Commission as it was crafting the EU Digital Services Act legislation introducing new and sweeping requirements for technology platforms. Our body of work on YouTube’s recommendation algorithm — both the findings themselves and the gap in independent research to uncover platform issues — highlighted the need for transparency of technology platforms and independent researcher access to platform data. &lt;/p&gt;
  4637.  
  4638.  
  4639.  
  4640. &lt;p&gt;In response to press inquiries and mounting consumer pressure, YouTube product leaders questioned the validity of our research findings and recommendations. However, the increased public scrutiny and our ongoing, direct conversations with YouTube leadership appeared to spark significant changes within YouTube. In 2021 and 2022, the company announced a series of voluntary changes to better surface “helpful” content and reduce recommendations based on engagement metrics alone.  &lt;/p&gt;
  4641.  
  4642.  
  4643.  
  4644. &lt;p&gt;The greatest changes came as a result of the passage of the EU Digital Services Act, which requires platforms like YouTube to grant independent researchers access to platform data to identify and advocate for improvements. Starting in 2023, YouTube opened its doors to independent researchers and research is underway. The “YouTube Regrets” research was cited in the Digital Services Act language, validating the need and impact of platform research of this kind. Mozilla’s community-backed campaign not only succeeded in changing one powerful platform but also creating a groundswell of support for transparency across technology platforms.&lt;/p&gt;
  4645.  
  4646.  
  4647.  
  4648. &lt;h4&gt;&lt;strong&gt;Building alternatives&lt;/strong&gt; &lt;/h4&gt;
  4649.  
  4650.  
  4651.  
  4652. &lt;p&gt;Sometimes, responsible alternatives simply don’t exist and must be created from scratch. This option can be daunting but doable by mission-based organizations, particularly those with engaged communities. Building tech alternatives through the power of community is the “architecture of participation” in action&lt;/p&gt;
  4653.  
  4654.  
  4655.  
  4656. &lt;p&gt;Mozilla undertook this approach when launching an initiative to address bias in voice recognition systems caused by limited training data.  Beginning in 2017, Mozilla set out to build an open dataset of diverse voices through crowdsourcing and consensual data collection. The goal was to build a dataset of underserved languages, accents and ages in order to power equitable speech recognition technology. Today, Common Voice is the world’s largest crowdsourced open speech dataset, and enables community and commercial projects to offer voice-enabled services in underrepresented languages.&lt;/p&gt;
  4657.  
  4658.  
  4659.  
  4660. &lt;p&gt;Common Voice’s dataset was created (and continues to grow) from thousands of hours of speech contributions from the Mozilla community and beyond. To engage Mozilla’s existing and new supporters, we shared our vision of advancing equitable speech recognition technology and created a highly accessible platform to solicit contributions. Importantly, speech contributions and other volunteer activities do not require technical or AI expertise, making it highly accessible to a wide range of supporters. To date, we’ve collected over 33,000 hours of voice data in 300 languages contributed by more than 750,000 people. &lt;/p&gt;
  4661.  
  4662.  
  4663.  
  4664. &lt;p&gt;With voice clips donated by volunteers on every continent Common Voice reflects real-world speech and centers underrepresented voices. It’s more than just infrastructure — it’s a movement for data dignity and linguistic justice, and proves that open data can be powerful, participatory, and global. The project is now being used to train machine learning models, so that AI all over the world is more inclusive.&lt;/p&gt;
  4665.  
  4666.  
  4667.  
  4668. &lt;h3&gt;&lt;strong&gt;Conclusion &lt;/strong&gt;&lt;/h3&gt;
  4669.  
  4670.  
  4671.  
  4672. &lt;p&gt;Mozilla’s three-pronged experiment in innovative advocacy strategies — empowering consumers, shaping products, and building alternatives — offers a potential model for mission-driven organizations that seek to create lasting social impact while maintaining financial growth. This strategy has shaken up the big tech landscape, and driven massive impact. &lt;/p&gt;
  4673.  
  4674.  
  4675.  
  4676. &lt;p&gt;As the internet has transformed in the age of AI, so has Mozilla. Mozilla Foundation’s advocacy work continues, with urgent campaigns on issues like surveillance tech. Mozilla Corporation and MZLA are transforming Firefox and Thunderbird for a new era through adoption of emerging technologies. Mozilla Ventures, an impact fund, is investing in dozens of founders and start-ups, seeding a new generation of companies committed to the Mozilla Manifesto. And &lt;a href=&quot;http://mozilla.ai&quot;&gt;Mozilla.ai&lt;/a&gt;, an AI incubator, aims to empower developers with trustworthy AI. &lt;/p&gt;
  4677.  
  4678.  
  4679.  
  4680. &lt;p&gt;Mozilla’s mission remains a double bottom line: advancing our manifesto and succeeding in the market, so we can do even more to build a better internet, and better AI, with people, for  people.  &lt;/p&gt;

  4856.  
  4857.  
  4858.  
  4859. &lt;p&gt;It’s a terrible experience when you’re enjoying a video or music on YouTube and you’re suddenly interrupted by a blaring ad. &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/sponsorblock/&quot; rel=&quot;noreferrer noopener&quot;&gt;SponsorBlock&lt;/a&gt; solves this problem in a highly effective and original way. &lt;/p&gt;

  4863. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  4864.  
  4865.  
  4866.  
  4867. &lt;p&gt;Leveraging the power of crowd sourced information to locate where—precisely— interruptive sponsored segments appear in videos, SponsorBlock learns where to automatically skip sponsored segments with its ever growing database of videos. You can also participate in the project by reporting sponsored segments whenever you encounter them (it’s easy to report right there on the video page with the extension). &lt;/p&gt;
  4868.  
  4869.  
  4870.  
  4871. &lt;p&gt;SponsorBlock can also learn to skip non-music portions of music videos and intros/outros, as well. If you’d like a deeper dive of SponsorBlock we profiled its developer and open source project on &lt;a href=&quot;https://blog.mozilla.org/products/firefox/firefox-extension-sponsorblock/&quot; rel=&quot;noreferrer noopener&quot;&gt;Mozilla Distilled&lt;/a&gt;. &lt;/p&gt;
  4872.

  4875. &lt;p&gt;We hope one of these extensions enhances the way you enjoy YouTube.

  4896. <title>The Mozilla Blog: Who does Gen Z trust outside the algorithm?</title>
  4897. <guid isPermaLink="false">https://blog.mozilla.org/?p=81380</guid>
  4898. <link>https://blog.mozilla.org/en/internet-culture/gen-z-algorithm/</link>
  4899. <description>&lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;A teal smartphone with triple rear cameras lies on green grass, next to the shadow of an outstretched arm.&quot; class=&quot;wp-image-81381&quot; height=&quot;683&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/08/josue-sanchez-djF9d8KmK7A-unsplash-1024x683.jpg&quot; width=&quot;1024&quot; /&gt;&lt;/figure&gt;
  4900.  
  4901.  
  4902.  
  4903. &lt;p&gt;&lt;em&gt;This essay was originally published on &lt;a href=&quot;https://mozillasidebar.substack.com/p/gen-z-algorithm&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;The Sidebar, Mozilla’s Substack&lt;/a&gt;.&lt;/em&gt;&lt;/p&gt;
  4904.  
  4905.  
  4906.  
  4907. &lt;p&gt;When I started my newsletter, &lt;a href=&quot;https://asseenonbyochuko.substack.com/&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;&lt;em&gt;as seen on&lt;/em&gt;&lt;/a&gt;, a little over a year ago, it was because in the absence of early morning commutes, a designated office desk, and the water cooler conversations I’d been told to expect but had yet to experience, my group chats became the default space where I learned about and made sense of the world. Made up mostly of recent graduates like myself, they filled the void of a shared professional context. If I wasn’t spending my paid-for hours scrolling TikTok or X, I knew someone who was.&lt;/p&gt;
  4908.  
  4909.  
  4910.  
  4911. &lt;p&gt;Anecdotes of bad dates and personal drama were interspersed with links from &lt;em&gt;The Times&lt;/em&gt; and &lt;em&gt;The Wall Street Journal&lt;/em&gt;. TikTok explainers from unknown creators were often given nearly the same weight as bylines from legacy publishers — not because everything was taken at face value, but because nothing was above debate. In hindsight, I realize these chats were doing more than just filling the gap. They were functioning as my second algorithm, reshaping what I paid attention to and how I processed it.&lt;/p&gt;
  4912.  
  4913.  
  4914.  
  4915. &lt;h3&gt;&lt;strong&gt;The feed is raw material, the group chat is the filter&lt;/strong&gt;&lt;/h3&gt;
  4916.  
  4917.  
  4918.  
  4919. &lt;p&gt;It’s true that when a Zoomer says, “I read this somewhere,” they probably mean, “I saw it on TikTok.” In the U.S., more than half of people under 35 now consider social and video platforms their primary news source, surpassing TV and legacy news websites. Globally, &lt;a href=&quot;https://www.reuters.com/world/us/us-news-consumers-are-turning-podcaster-joe-rogan-away-traditional-sources-2025-06-16/?utm_source=chatgpt.com&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;about 44% of people aged 18 to 24&lt;/a&gt; say social and video platforms are their main source of news. Recent data from &lt;a href=&quot;https://www.pewresearch.org/short-reads/2024/09/17/more-americans-regularly-get-news-on-tiktok-especially-young-adults/https://www.pewresearch.org/short-reads/2024/09/17/more-americans-regularly-get-news-on-tiktok-especially-young-adults/&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;Pew&lt;/a&gt; and the Reuters Institute also show that around 44% of U.S. adults aged 18 to 29 cite TikTok as their go-to news source.&lt;/p&gt;
  4920.  
  4921.  
  4922.  
  4923. &lt;p&gt;If social platforms are the front page of Gen Z’s internet, then group chats are the private newsrooms — spaces where algorithm-fed content is interpreted, validated, and repurposed into something more intimate and trusted. A TikTok isn’t truly viral until it hits the group chat. Breaking news is hardly relevant unless it sparks debate. In a fragmented information landscape, group chats have become the second algorithm.&lt;/p&gt;
  4924.  
  4925.  
  4926.  
  4927. &lt;figure class=&quot;wp-block-pullquote&quot;&gt;&lt;blockquote&gt;&lt;p&gt;The links and conversations circulating in these chats amount to an ongoing, personalized curation — a feed shaped not by tech companies but by people I trust.&lt;/p&gt;&lt;/blockquote&gt;&lt;/figure&gt;
  4928.  
  4929.  
  4930.  
  4931. &lt;p&gt;As a 26-year-old, college-educated immigrant who’s lived in five cities over the past decade, my group chats reflect the many pockets of friends and acquaintances I’ve gathered along the way. Each one captures a different version of my life, a snapshot of my tastes and worldviews at a specific moment. The links and conversations circulating in these chats amount to an ongoing, personalized curation — a feed shaped not by tech companies but by people I trust.&lt;/p&gt;
  4932.  
  4933.  
  4934.  
  4935. &lt;h3&gt;&lt;strong&gt;Trust is peer-to-peer, not platform-based&lt;/strong&gt;&lt;/h3&gt;
  4936.  
  4937.  
  4938.  
  4939. &lt;p&gt;Legacy media has a trust problem. When Gallup began tracking Americans’ views of the news media in the early 1970s, attitudes were overwhelmingly positive. Since then, public confidence has steadily declined. In &lt;a href=&quot;https://news.gallup.com/poll/651977/americans-trust-media-remains-trend-low.aspx?utm_source=chatgpt.com&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;Gallup’s 2024 survey&lt;/a&gt;, only 31% of Americans said they had a “great deal” or “fair amount” of trust in mass media. Meanwhile, 36% said they had no trust at all — the highest level ever recorded.&lt;/p&gt;
  4940.  
  4941.  
  4942.  
  4943. &lt;p&gt;But when the algorithm replaces the Fourth Estate, we trade institutional scrutiny for viral consensus. And that carries its own risks. Social feeds are flooded with conflicting, contextless information. The more sensational, the more it spreads.&lt;/p&gt;
  4944.  
  4945.  
  4946.  
  4947. &lt;p&gt;Gen Z, raised on the internet, is aware of this. Contrary to the popular narrative, media literacy isn’t dead — it just looks different. Concepts like “source layering” or “context collapse” aren’t theoretical to us, they play out in real time. Much like how consumers now trust friends and influencers over brands, young people don’t just trust a source — they trust the person sharing it. For better or worse, credibility has become relational.&lt;/p&gt;
  4948.  
  4949.  
  4950.  
  4951. &lt;h3&gt;&lt;strong&gt;Group chats as media infrastructure&lt;/strong&gt;&lt;/h3&gt;
  4952.  
  4953.  
  4954.  
  4955. &lt;p&gt;It’s helpful to consider scale when thinking about how information moves today. In an age of overwhelming information abundance, and in the absence of a collective narrative, taste and trust have become the ultimate social currencies. Social proof isn’t mass appeal — it’s micro-appeal, measured by how it resonates within your own circles. Unlike public-facing algorithms, group chats operate through collective filtering. What gets boosted in a chat has already been socially vetted and reframed. &lt;/p&gt;
  4956.  
  4957.  
  4958.  
  4959. &lt;p&gt;Just as a Rolodex once reflected the strength of your network, I’ve come to see the depth and variety of my group chats as a key tool for making sense of the world. When I drop a link to a TikTok or a news article and type, “Did you guys see this?”, I’m not just sharing — I’m soliciting context. The responses are as varied as the chats themselves, spanning industries, countries, and personal biases. The links I get in return, whether to debunk or reinforce a claim, offer a window into my peers’ algorithms, often refreshingly different from my own.&lt;/p&gt;
  4960.  
  4961.  
  4962.  
  4963. &lt;p&gt;Take a video of a CEO fumbling a question about worker safety. In one group chat, it sparks a detailed conversation about labor policy. In another, someone shares the full clip to push back on claims of bad faith editing. In a third, it becomes a meme. One video, three interpretations — shaped not by the algorithm, but by the lens of the group watching it.&lt;/p&gt;
  4964.  
  4965.  
  4966.  
  4967. &lt;p&gt;Group chats have become more than places to gossip or trade memes. They are cultural processors, fact-checking hubs, and micro-editorial boards. In a media ecosystem where traditional institutions have lost authority and algorithms feel increasingly chaotic, it makes sense that Gen Z turns inward. What we trust now isn’t just the content — it’s the people helping us understand it.&lt;/p&gt;
  4968.  
  4969.  
  4970.  
  4971. &lt;a class=&quot;ft-c-inline-cta&quot; href=&quot;https://www.mozilla.org/firefox/new/&quot;&gt;

  4982. <title>The Mozilla Blog: It doesn’t have to be like this — join Firefox in #DailyDefiance</title>
  4983. <guid isPermaLink="false">https://blog.mozilla.org/?p=81393</guid>
  4984. <link>https://blog.mozilla.org/en/firefox/firefox-wants-you-join-daily-defiance/</link>
  4985. <description>&lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;Four people joining together for #dailydefiance&quot; class=&quot;wp-image-81394&quot; height=&quot;683&quot; src=&quot;https://blog.mozilla.org/wp-content/blogs.dir/278/files/2025/08/vonecia-carswell-0aMMMUjiiEQ-unsplash-1024x683.jpg&quot; width=&quot;1024&quot; /&gt;&lt;/figure&gt;
  4986.  
  4987.  
  4988.  
  4989. &lt;p&gt;Where has the default got us? Today, the default means sitting by while Big Tech and The Billionaires who run the industry shape every aspect of your life — who gets funding, who has access to your data and whose pockets get lined by the profits. &lt;/p&gt;
  4990.  
  4991.  
  4992.  
  4993. &lt;p&gt;But humanity has a history of pushing back, and so does Firefox. In 2004, &lt;a href=&quot;http://blog.mozilla.org/en/products/firefox/firefox-milestones/&quot;&gt;Firefox was born&lt;/a&gt; out of an act of defiance. At the time Internet Explorer wasn’t just the leading browser, but a juggernaut, with over 90% of market share. The truth is when only one entity exists in a space, there is no force for innovation, and it leads to stagnation. Enter: Firefox, a faster, more secure and open-source alternative.&lt;/p&gt;
  4994.  
  4995.  
  4996.  
  4997. &lt;p&gt;That drive for innovation continues today. In an era where most tech companies chase profit margins and market dominance, we have consistently done the opposite. &lt;strong&gt;Firefox has a history of not just innovation, but defiance.&lt;/strong&gt;&lt;/p&gt;
  4998.  
  4999.  
  5000.  
  5001. &lt;p&gt;Defiance against centralization.&lt;/p&gt;
  5002.  
  5003.  
  5004.  
  5005. &lt;p&gt;Defiance against profit over people.&lt;/p&gt;
  5006.  
  5007.  
  5008.  
  5009. &lt;p&gt;Defiance against the status quo.&lt;/p&gt;
  5010.  
  5011.  
  5012.  
  5013. &lt;p&gt;Firefox is built differently — both the product and the organizational structure. It is built in a way to best push back against the defaults of Big Tech. Firefox is the only major browser not backed by a billionaire or built on Chromium’s browser engine. Instead, Firefox is backed by a non-profit, so we never have to put shareholders or a billionaire over the people who use Firefox. It also maintains and runs on Gecko, a flexible, independent, open-source browser engine.&lt;/p&gt;
  5014.  
  5015.  
  5016.  
  5017. &lt;p&gt;People have made the internet great, not billionaires. And we know that people are doing great things online and offline right now to shape not just a better internet, but a better world. It can feel daunting to go against the status quo, but small acts of defiance do matter. This can look like supporting the public library, volunteering at your community garden, contributing to an open-source project, joining a local buy nothing group, or volunteering with a local organization. &lt;/p&gt;
  5018.  
  5019.  
  5020.  
  5021. &lt;p&gt;These moments of soft rebellion are what help put power in the hands of the people, the many, and not just the elite. We believe most people participate in acts of defiance daily, especially the members of our Firefox community.&lt;/p&gt;
  5022.  
  5023.  
  5024.  
  5025. &lt;p&gt;So starting today, join us in sharing your act of daily defiance using #dailydefiance and tagging @firefox on social channels to be a part of our movement to remind the world that everyday choices do matter, and we should all choose boldly.&lt;/p&gt;
  5026.  
  5027.

  5044. <title>Mozilla Privacy Blog: The EU’s AI Act at One Year: Continuing to push for open-source AI and transparency</title>
  5045. <guid isPermaLink="false">https://blog.mozilla.org/netpolicy/?p=2492</guid>
  5046. <link>https://blog.mozilla.org/netpolicy/2025/08/11/the-eus-ai-act-at-one-year-continuing-to-push-for-open-source-ai-and-transparency/</link>
  5047. <description>&lt;p&gt;&lt;strong&gt;&lt;i&gt;Saturday, August 2, marked the first anniversary of the entry into force of the EU AI Act, the EU’s contested landmark legislation putting in place rules for AI sold and deployed on its internal market. With a staggered timeline for when different rules take effect, Mozilla continues its work to ensure that the law’s implementation is a success. &lt;/i&gt;&lt;/strong&gt;&lt;/p&gt;
  5048. &lt;p&gt;Beginning last week, the AI Act imposes new obligations for the developers of so-called “general-purpose AI models” (GPAI), that is, large AI models like OpenAI’s GPT, Google’s Gemini, or xAI’s Grok models (often also refered to as “foundation models”). Mozilla has &lt;a href=&quot;https://web.archive.org/web/20250708083113/https://www.mozillafoundation.org/en/blog/how-to-make-sure-the-eu-ai-act-delivers-on-its-promise/&quot;&gt;long advocated&lt;/a&gt; for such rules to be included in the AI Act to ensure that large AI labs must play their part in making the technology they develop safer and more transparent and that due diligence obligations are not entirely passed down the value chain to smaller developers and deployers. These new rules include new transparency and disclosure mandates as well as obligations relating to GPAI developers safety and security practices.&lt;/p&gt;
  5049. &lt;p&gt;To mark the occasion, Mozilla, in partnership with Hugging Face and Linux Foundation, &lt;a href=&quot;https://huggingface.co/blog/yjernite/eu-act-os-guideai&quot;&gt;published a guide for open-source AI developers&lt;/a&gt; aiming to help them navigate these rules. Amongst other questions, the guide explains what exactly constitutes a GPAI model or a “GPAI model with systemic risk”, what obligations developers need to meet, and when they might benefit from the AI Act’s exemptions for open-source AI. It builds on and synthesizes the recently adopted &lt;a href=&quot;https://digital-strategy.ec.europa.eu/en/policies/contents-code-gpai&quot;&gt;Code of Practice for GPAI developers&lt;/a&gt; as well as the European Commission’ newly published &lt;a href=&quot;https://digital-strategy.ec.europa.eu/en/library/guidelines-scope-obligations-providers-general-purpose-ai-models-under-ai-act&quot;&gt;GPAI guidelines&lt;/a&gt;. The guide also includes an interactive flowchart meant to help developers on their AI Act “user journey”. This builds on Mozilla’s long-standing work advocating for better conditions for open-source AI development, including our advocacy to ensure that open-source developers receive proportionate treatment under the AI Act.&lt;/p&gt;
  5050. &lt;p&gt;In addition, in late July, the European Commission also published a template for the “sufficiently detailed summary” that GPAI developers are now mandated to publish about the data used to train their AI models. While the template falls short of expectations in many respects, it does in parts mirror &lt;a href=&quot;https://openfuture.eu/wp-content/uploads/2024/06/240618AIAtransparency_template_requirements-2.pdf&quot;&gt;recommendations&lt;/a&gt; made by Mozilla &lt;a href=&quot;https://openfuture.eu/wp-content/uploads/2024/09/240919AIAtransparency_template_requirements-blueprint_v.2.0.pdf&quot;&gt;building on&lt;/a&gt; &lt;a href=&quot;https://www.techpolicy.press/how-the-eu-ai-act-can-increase-transparency-around-ai-training-data/&quot;&gt;our work&lt;/a&gt; &lt;a href=&quot;https://euobserver.com/digital/ara7bbd63b&quot;&gt;in partnership&lt;/a&gt; with Open Future over the past year.&lt;/p&gt;
  5051. &lt;p&gt;With additional rules taking effect over the course of the coming years and the European Commission building up its capacity to enforce them, work on the AI Act is not over — it is entering a new phase. Amid discussions of regulatory simplification, a potential revision of the AI Act in the context of the EU’s omnibus, and calls to “stop the clock” on enforcing the AI Act, Mozilla will continue its work to help make the AI Act’s implementation a success. This is grounded in our conviction that good regulation and innovation aren’t inherently contradictory, but rather complements when it comes to steering innovation in a direction that is beneficial to all.&lt;/p&gt;

  5060. <description>&lt;a href=&quot;https://arstechnica.com/gadgets/2025/08/rip-to-the-macintosh-hd-hard-drive-icon-2000-2025/&quot;&gt;Ars Technica mentioned&lt;/a&gt; that in &lt;a href=&quot;http://tenfourfox.blogspot.com/2025/06/macos-tahoe.html&quot;&gt;macOS Tahoe&lt;/a&gt; the venerable old hard disk icons will be replaced with new, more generic, relatively less interesting equivalents. This process also apparently happens with Apple CEOs from time to time. If you are on Sequoia and want to keep them for posterity, you can get them out of &lt;tt&gt;/System/Library/Extensions/IOStorageFamily.kext/Contents/Resources&lt;/tt&gt;. I'm still impressed to this day that someone not only took the time to write actually plausible text copy for the label, but also gave it Torx screws. Get out your T8 MacCracker for this drive:

  5063.  
  5064. This isn't the only echo of Macs past in the operating system. &lt;a href=&quot;https://www.spacebar.news/apple-history-hiding-in-mac-font/&quot;&gt;The Spacebar&lt;/a&gt; also noticed that Apple Symbols still has many old, nay, &quot;obsolete&quot; icons that are only of use to people who still use web browsers on Power Macs.
  5065.  
  5066. &lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieADu0-wXBMQH_W9_gsTQ5D24EcpCBQbB4w0hF4NzWhsOMpQFZW1EoRvyw0x3BVgmKhQmyn1YLg3VXKYe9_fnQr_zC1tZiNtYQEC05UabQbf14KtzwlDsAmgADTqlSa_oxQMvV-DE_j0238oz-_-3sAwAvnV1Bgtb9VZ3H9Dg3AMRT7wOdmVu8hiyKuOno/s3552/Screenshot%202025-08-06%20at%205.44.43%E2%80%AFPM.png&quot; style=&quot;display: block; padding: 1em 0; text-align: center;&quot;&gt;&lt;img alt=&quot;&quot; border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieADu0-wXBMQH_W9_gsTQ5D24EcpCBQbB4w0hF4NzWhsOMpQFZW1EoRvyw0x3BVgmKhQmyn1YLg3VXKYe9_fnQr_zC1tZiNtYQEC05UabQbf14KtzwlDsAmgADTqlSa_oxQMvV-DE_j0238oz-_-3sAwAvnV1Bgtb9VZ3H9Dg3AMRT7wOdmVu8hiyKuOno/s320/Screenshot%202025-08-06%20at%205.44.43%E2%80%AFPM.png&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
  5067.  
  5068. That's not the half of it, though. There's a bunch more in that file than the ones he spotted. Here's what I saw; perhaps you can find more.
  5069.  
  5070. &lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEisfewYuIj0Id6WTojGA6X6qYfPwz4-aa99S91PZViF4FnVlAEkd1aeAgaTlW_JchYMPtnOa6Mi8R5HGQwlgk1nnqFxBBsLpt_5_ZFkTASDzKJW6LN0Rp-HcJ6fQyGQO_BL2_WBPfWnNL7eVcJyzzeZCUAi8l87ReZ8jeFI-nt6DRVYvM3cTqN9Lwv_8sLg/s2000/charsheet.png&quot; style=&quot;display: block; padding: 1em 0; text-align: center;&quot;&gt;&lt;img alt=&quot;&quot; border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEisfewYuIj0Id6WTojGA6X6qYfPwz4-aa99S91PZViF4FnVlAEkd1aeAgaTlW_JchYMPtnOa6Mi8R5HGQwlgk1nnqFxBBsLpt_5_ZFkTASDzKJW6LN0Rp-HcJ6fQyGQO_BL2_WBPfWnNL7eVcJyzzeZCUAi8l87ReZ8jeFI-nt6DRVYvM3cTqN9Lwv_8sLg/s320/charsheet.png&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
  5071.  
  5072. In order: PowerPC logo, composite video out and in, S-video out and in (such as seen on some later PowerBooks), modem port, combined modem/printer port (like on the Duo 2300), printer port, SCSI, Ethernet (also AAUI), three glyphs for Apple Desktop Bus (ADB) ports, a server, rainbow outline Apple, Balloon Help (from System 7), Apple Guide (7.5), 5.25&quot; floppy (I guess mostly for the Apple II folks), two Newton lightbulbs, Newton undo, Newton extras, Newton dates, Newton names, high-density 3.5&quot; disk icon, a confused Compact Mac (possibly to evoke the flashing question mark when it can't find a bootable volume), classic QuickTime logo, busy watch, Apple Pro Speakers port (such as on the iMac G4 or the MDD G4), FireWire, programmer's key icon, and two versions of the reset icon, though these three do have Unicode equivalents or you can also use regular geometric shapes, and sometimes those faced the other way.
  5073. &lt;p&gt;
  5074. (A note on most of these characters is that they don't actually map to any defined Unicode code point; they are unconnected glyphs. Font Book will show them but you can't really copy them anywhere. A tool like Ultra Character Map will let you at least grab a graphical representation and paste it somewhere, as I have done here.)
  5075. &lt;/p&gt;&lt;p&gt;
  5076. But that's not all! Feast your eyes on what's still in &lt;tt&gt;/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources&lt;/tt&gt;!
  5077. &lt;/p&gt;&lt;p&gt;
  5078. &lt;a name=&quot;more&quot;&gt;&lt;/a&gt;
  5079. What's particularly impressive is the &lt;em&gt;multiple sizes&lt;/em&gt; for systems with differently sized screens as options. These are taken from the 1024x1024 144dpi retina versions in Sequoia.

  5138. and who let this thing in?
  5139. &lt;p&gt;
  5140. Why are all these things still in the macOS? My guess, modulo the Blue Screen PC, is trademark purposes.&lt;i&gt;[A number of people have suggested for network serves; some servers will identify themselves as specific computers, which will pick up an icon in this group, and of course the Windows PC for this purpose is well-known. Fine, except that this archive isn't comprehensive for all the possible Mac models that could have participated as a network share point: no G3s, for example, and no Power Mac G5.]&lt;/i&gt; These all were used as Apple-specific labeling and could be considered as part of their trade dress, and having these legacy items still in the macOS probably serves some legal purpose if someone were to try to rip off their old IP. It can't be for nostalgia purposes or we'd still be able to run Carbon PowerPC apps on Tahoe like you can still run most Win32 applications on Windows 11. And Apple just doesn't &lt;em&gt;do&lt;/em&gt; nostalgia — except in their ads.&lt;/p&gt;</description>

  5145. <title>The Rust Programming Language Blog: Announcing Rust 1.89.0</title>
  5146. <guid isPermaLink="true">https://blog.rust-lang.org/2025/08/07/Rust-1.89.0/</guid>
  5147. <link>https://blog.rust-lang.org/2025/08/07/Rust-1.89.0/</link>
  5148. <description>&lt;p&gt;The Rust team is happy to announce a new version of Rust, 1.89.0. Rust is a programming language empowering everyone to build reliable and efficient software.&lt;/p&gt;
  5149. &lt;p&gt;If you have a previous version of Rust installed via &lt;code&gt;rustup&lt;/code&gt;, you can get 1.89.0 with:&lt;/p&gt;
  5150. &lt;pre class=&quot;language-console z-code&quot;&gt;&lt;code class=&quot;language-console&quot;&gt;&lt;span class=&quot;z-text z-plain&quot;&gt;$ rustup update stable
  5151. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  5152. &lt;p&gt;If you don't have it already, you can &lt;a href=&quot;https://www.rust-lang.org/install.html&quot;&gt;get &lt;code&gt;rustup&lt;/code&gt;&lt;/a&gt; from the appropriate page on our website, and check out the &lt;a href=&quot;https://doc.rust-lang.org/stable/releases.html#version-1890-2025-08-07&quot;&gt;detailed release notes for 1.89.0&lt;/a&gt;.&lt;/p&gt;
  5153. &lt;p&gt;If you'd like to help us out by testing future releases, you might consider updating locally to use the beta channel (&lt;code&gt;rustup default beta&lt;/code&gt;) or the nightly channel (&lt;code&gt;rustup default nightly&lt;/code&gt;). Please &lt;a href=&quot;https://github.com/rust-lang/rust/issues/new/choose&quot;&gt;report&lt;/a&gt; any bugs you might come across!&lt;/p&gt;
  5154. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/08/07/Rust-1.89.0/#what-s-in-1-89-0-stable&quot;&gt;&lt;/a&gt;
  5155. What's in 1.89.0 stable&lt;/h3&gt;
  5156. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/08/07/Rust-1.89.0/#explicitly-inferred-arguments-to-const-generics&quot;&gt;&lt;/a&gt;
  5157. Explicitly inferred arguments to const generics&lt;/h4&gt;
  5158. &lt;p&gt;Rust now supports &lt;code&gt;_&lt;/code&gt; as an argument to const generic parameters, inferring the value from surrounding context:&lt;/p&gt;

  5212. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  5213. &lt;p&gt;We then realized that the confusion we want to eliminate occurs when both&lt;/p&gt;
  5214. &lt;ol&gt;
  5215. &lt;li&gt;lifetime elision inference rules &lt;em&gt;connect&lt;/em&gt; an input lifetime to an output lifetime&lt;/li&gt;
  5216. &lt;li&gt;it's not syntactically obvious that a lifetime exists&lt;/li&gt;
  5217. &lt;/ol&gt;
  5218. &lt;p&gt;There are two pieces of Rust syntax that indicate that a lifetime exists: &lt;code&gt;&amp;amp;&lt;/code&gt; and &lt;code&gt;'&lt;/code&gt;, with &lt;code&gt;'&lt;/code&gt; being subdivided into the inferred lifetime &lt;code&gt;'_&lt;/code&gt; and named lifetimes &lt;code&gt;'a&lt;/code&gt;. When a type uses a named lifetime, lifetime elision will not infer a lifetime for that type. Using these criteria, we can construct three groups:&lt;/p&gt;
  5219. &lt;table&gt;&lt;thead&gt;&lt;tr&gt;&lt;th&gt;Self-evident it has a lifetime&lt;/th&gt;&lt;th&gt;Allow lifetime elision to infer a lifetime&lt;/th&gt;&lt;th&gt;Examples&lt;/th&gt;&lt;/tr&gt;&lt;/thead&gt;&lt;tbody&gt;
  5220. &lt;tr&gt;&lt;td&gt;No&lt;/td&gt;&lt;td&gt;Yes&lt;/td&gt;&lt;td&gt;&lt;code&gt;ContainsLifetime&lt;/code&gt;&lt;/td&gt;&lt;/tr&gt;
  5221. &lt;tr&gt;&lt;td&gt;Yes&lt;/td&gt;&lt;td&gt;Yes&lt;/td&gt;&lt;td&gt;&lt;code&gt;&amp;amp;T&lt;/code&gt;, &lt;code&gt;&amp;amp;'_ T&lt;/code&gt;, &lt;code&gt;ContainsLifetime&amp;lt;'_&amp;gt;&lt;/code&gt;&lt;/td&gt;&lt;/tr&gt;
  5222. &lt;tr&gt;&lt;td&gt;Yes&lt;/td&gt;&lt;td&gt;No&lt;/td&gt;&lt;td&gt;&lt;code&gt;&amp;amp;'a T&lt;/code&gt;, &lt;code&gt;ContainsLifetime&amp;lt;'a&amp;gt;&lt;/code&gt;&lt;/td&gt;&lt;/tr&gt;
  5223. &lt;/tbody&gt;&lt;/table&gt;
  5224. &lt;p&gt;The &lt;code&gt;mismatched_lifetime_syntaxes&lt;/code&gt; lint checks that the inputs and outputs of a function belong to the same group. For the initial motivating example above, &lt;code&gt;&amp;amp;[u8]&lt;/code&gt; falls into the second group while &lt;code&gt;std::slice::Iter&amp;lt;u8&amp;gt;&lt;/code&gt; falls into the first group. We say that the lifetimes in the first group are &lt;em&gt;hidden&lt;/em&gt;.&lt;/p&gt;
  5225. &lt;p&gt;Because the input and output lifetimes belong to different groups, the lint will warn about this function, reducing confusion about when a value has a meaningful lifetime that isn't visually obvious.&lt;/p&gt;
  5226. &lt;p&gt;The &lt;code&gt;mismatched_lifetime_syntaxes&lt;/code&gt; lint supersedes the &lt;code&gt;elided_named_lifetimes&lt;/code&gt; lint, which did something similar for named lifetimes specifically.&lt;/p&gt;
  5227. &lt;p&gt;Future work on the &lt;code&gt;elided_lifetimes_in_paths&lt;/code&gt; lint intends to split it into more focused sub-lints with an eye to warning about a subset of them eventually.&lt;/p&gt;

  5229. More x86 target features&lt;/h4&gt;
  5230. &lt;p&gt;The &lt;code&gt;target_feature&lt;/code&gt; attribute now supports the &lt;code&gt;sha512&lt;/code&gt;, &lt;code&gt;sm3&lt;/code&gt;, &lt;code&gt;sm4&lt;/code&gt;, &lt;code&gt;kl&lt;/code&gt; and &lt;code&gt;widekl&lt;/code&gt; target features on x86. Additionally a number of &lt;code&gt;avx512&lt;/code&gt; intrinsics and target features are also supported on x86:&lt;/p&gt;

  5248. &lt;p&gt;&lt;code&gt;i128&lt;/code&gt; and &lt;code&gt;u128&lt;/code&gt; no longer trigger the &lt;code&gt;improper_ctypes_definitions&lt;/code&gt; lint, meaning these types may be used in &lt;code&gt;extern &quot;C&quot;&lt;/code&gt; functions without warning. This comes with some caveats:&lt;/p&gt;
  5249. &lt;ul&gt;
  5250. &lt;li&gt;The Rust types are ABI- and layout-compatible with (unsigned) &lt;code&gt;__int128&lt;/code&gt; in C when the type is available.&lt;/li&gt;
  5251. &lt;li&gt;On platforms where &lt;code&gt;__int128&lt;/code&gt; is not available, &lt;code&gt;i128&lt;/code&gt; and &lt;code&gt;u128&lt;/code&gt; do not necessarily align with any C type.&lt;/li&gt;
  5252. &lt;li&gt;&lt;code&gt;i128&lt;/code&gt; is &lt;em&gt;not&lt;/em&gt; necessarily compatible with &lt;code&gt;_BitInt(128)&lt;/code&gt; on any platform, because &lt;code&gt;_BitInt(128)&lt;/code&gt; and &lt;code&gt;__int128&lt;/code&gt; may not have the same ABI (as is the case on x86-64).&lt;/li&gt;
  5253. &lt;/ul&gt;
  5254. &lt;p&gt;This is the last bit of follow up to the layout changes from last year: &lt;a href=&quot;https://blog.rust-lang.org/2024/03/30/i128-layout-update&quot;&gt;https://blog.rust-lang.org/2024/03/30/i128-layout-update&lt;/a&gt;.&lt;/p&gt;

This means that the target, including tools like &lt;code&gt;rustc&lt;/code&gt; and &lt;code&gt;cargo&lt;/code&gt;, will be guaranteed to build but is not guaranteed to pass our automated test suite.&lt;/p&gt;
  5259. &lt;p&gt;We expect that the RFC for the demotion to Tier 2 with host tools will be accepted between the releases of Rust 1.89 and 1.90, which means that Rust 1.89 will be the last release of Rust where &lt;code&gt;x86_64-apple-darwin&lt;/code&gt; is a Tier 1 target.&lt;/p&gt;
  5260. &lt;p&gt;For users, this change will not immediately cause impact. Builds of both the standard library and the compiler will still be distributed by the Rust Project for use via &lt;code&gt;rustup&lt;/code&gt; or alternative installation methods while the target remains at Tier 2. Over time, it's likely that reduced test coverage for this target will cause things to break or fall out of compatibility with no further announcements.&lt;/p&gt;

  5262. Standards Compliant C ABI on the &lt;code&gt;wasm32-unknown-unknown&lt;/code&gt; target&lt;/h4&gt;
  5263. &lt;p&gt;&lt;code&gt;extern &quot;C&quot;&lt;/code&gt; functions on the &lt;code&gt;wasm32-unknown-unknown&lt;/code&gt; target now have a standards compliant ABI.

  5313. <title>Mozilla Thunderbird: Engage Your Inbox with ‘Getting Things Done’</title>
  5314. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3692</guid>
  5315. <link>https://blog.thunderbird.net/2025/08/maximize-your-day-getting-things-done-with-thunderbird/</link>
  5316. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;321&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/Max-your-day-getting-things-done-method-1.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  5317. &lt;p&gt;David Allen’s &lt;a href=&quot;https://gettingthingsdone.com/what-is-gtd/&quot;&gt;“Getting Thing Done”&lt;/a&gt; (GTD) system has been around for longer than Thunderbird! First published in a book of the same name in 2001, this approach to productivity is focused on freeing your brain from chaos, giving it “focus, clarity, and confidence” for creativity and new ideas. As I’m also a fan of freedom from chaos, I decided to dive back into our productivity blogs and highlight how to use tags and keyboard shortcuts to use GTD in Thunderbird.&lt;/p&gt;
  5318.  
  5319.  
  5320.  
  5321. &lt;h3&gt;Five Steps to Get Things Done&lt;/h3&gt;
  5322.  
  5323.  
  5324.  
  5325. &lt;p&gt;To start, let’s summarize the GTD system, for anyone who might not be familiar. GTD uses five key steps to go from unorganized to unstoppable, whether in your inbox or elsewhere: Capture, Clarify, Organize, Reflect, and Engage. &lt;/p&gt;
  5326.  
  5327.  
  5328.  
  5329. &lt;p&gt;Let’s think about these steps in terms of managing your inbox! First, Capturing involves collecting the things that have your attention. In other instances, this could mean brainstorming a to-do list. For email, this means your inbox. Clarifying entails taking those items and figuring out what they mean. For the Getting Things Done system, you need to figure out if you can act on something (for example, an email) or not. If it’s not actionable, where does it needs to go Is this reference? Is this on hold for some reason? Or can it just go in the trash? &lt;/p&gt;
  5330.  
  5331.  
  5332.  
  5333. &lt;p&gt;Once this clarifying is done, it’s time to Organize, aka putting the things that have your attention or reminders of them in a place you can act on, whether that’s now or later. Reflecting isn’t a one-time step, but something you do consistently to fine-tune your system and make sure it’s still working for you.&lt;/p&gt;
  5334.  
  5335.  
  5336.  
  5337. &lt;p&gt;All of these steps make the last step, Engaging, possible. You have a system you can trust, honed through reflection. Your inbox management system is like a starship where everything and everyone is working together, efficiently and effectively. This frees up your brain so your brain can soar through a cosmos of deep, interesting, meaningful work. Maybe while drinking a cup of tea, Earl Grey, hot.&lt;/p&gt;
  5338.  
  5339.  
  5340.  
  5341. &lt;h3&gt;Using Tags and Keyboard Shortcuts to Clarify and Organize Your Inbox&lt;/h3&gt;
  5342.  
  5343.  
  5344.  
  5345. &lt;p&gt;Adapting the GTD system to your Thunderbird inbox takes advantages of two features I am coming to love: labels and keyboard shortcuts.&lt;/p&gt;
  5346.  
  5347.  
  5348.  
  5349. &lt;p&gt;I’m going to suggest three initial labels, and a few possibilities for labels for non-actionable emails, and walk you through how to set up the labels and use the keyboard shortcuts to apply them – with screenshots!&lt;/p&gt;
  5350.  
  5351.  
  5352.  
  5353. &lt;p&gt;First, go into Settings &amp;gt; General &amp;gt; Tags to create/adjust your tags. The four example tags we set are “Do Now,” “Do,” “Waiting For,” and “Later.”&lt;/p&gt;
  5354.  
  5355.  
  5356.  
  5357. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/08/Screenshot-2025-07-21-at-14.37.27.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3693&quot; height=&quot;1232&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/Screenshot-2025-07-21-at-14.37.27.png&quot; width=&quot;2402&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  5358.  
  5359.  
  5360.  
  5361. &lt;p&gt;Wait, why have a “Do Now” and “Do” tag? This tip came from &lt;a href=&quot;https://henkpostma.blogspot.com/2011/12/getting-things-done-with-thunderbird.html&quot;&gt;Henk Postma’s blog&lt;/a&gt;, who gave me a lot of inspiration. “Do Now” is urgent, and it needs doing without delay. “Do” doesn’t have this urgency, but the email is actionable.&lt;/p&gt;
  5362.  
  5363.  
  5364.  
  5365. &lt;p&gt;The “Waiting For” label means there’s something you need to act on this email. Maybe it’s more information, or permission. This label can keep hold those emails until you’re ready. The “Later” tag is a bit of a catch-all. Like reference information, or things you’re interested in but can’t pursue yet. Maybe you want to break down your “Later” labels. The choice is yours!&lt;/p&gt;
  5366.  
  5367.  
  5368.  
  5369. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/08/Screenshot-2025-07-21-at-16.29.46.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3699&quot; height=&quot;1398&quot; src=&quot;https://blog.thunderbird.net/files/2025/08/Screenshot-2025-07-21-at-16.29.46.png&quot; width=&quot;2594&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  5370.  
  5371.  
  5372.  
  5373. &lt;p&gt;Now that we have our labels set up, and associated with a number, we’re ready to start organizing. Once a message comes in, click the number for the tag you want. If you accidentally press the wrong number, don’t worry! Just press ‘0’ to clear whatever label you applied.&lt;/p&gt;
  5374.  
  5375.  
  5376.  
  5377. &lt;p&gt;And that’s it! Well, except putting your system into practice, and David Allen &lt;a href=&quot;https://gettingthingsdone.com/wp-content/uploads/2014/10/GettingEmail.pdf&quot;&gt;has some further advice&lt;/a&gt; on using GTD in your inbox. If you have any tips on how you make your email organization a habit and not an afterthought, I’d love to hear them! As always, if there’s a productivity topic you’d like me to explore, let me know in the comments!&lt;/p&gt;

  5383. <title>The Rust Programming Language Blog: Project goals update — July 2025</title>
  5384. <guid isPermaLink="true">https://blog.rust-lang.org/2025/08/05/july-project-goals-update/</guid>
  5385. <link>https://blog.rust-lang.org/2025/08/05/july-project-goals-update/</link>
  5386. <description>&lt;p&gt;The Rust Project is currently working towards a &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h1/goals.html&quot;&gt;slate of 40 project goals&lt;/a&gt;, with 3 of them designated as &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h1/goals.html#flagship-goals&quot;&gt;flagship goals&lt;/a&gt;. This post provides selected updates on our progress towards these goals (or, in some cases, lack thereof). The full details for any particular goal are available in its associated &lt;a href=&quot;https://github.com/rust-lang/rust-project-goals/issues?q=is%3Aissue%20state%3Aopen%20label%3AC-tracking-issue&quot;&gt;tracking issue on the rust-project-goals repository&lt;/a&gt;.&lt;/p&gt;
  5387. &lt;p&gt;This is the final update for the first half of 2025. We're in the process of selecting goals for the second half of the year.&lt;/p&gt;
  5388. &lt;p&gt;&lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/goals.html&quot;&gt;Here are the goals that are currently proposed for 2025H2&lt;/a&gt;.&lt;/p&gt;
  5389. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/08/05/july-project-goals-update/#flagship-goals&quot;&gt;&lt;/a&gt;
  5390. Flagship goals&lt;/h3&gt;
  5391. &lt;div class=&quot;mt2 mb3&quot; style=&quot;display: flex;&quot;&gt;
  5392.    &lt;div&gt;&lt;a href=&quot;https://github.com/rust-lang/rust-project-goals/issues/105&quot;&gt;&lt;strong&gt;Bring the Async Rust experience closer to parity with sync Rust&lt;/strong&gt;&lt;/a&gt;&lt;/div&gt;
  5393.    &lt;div&gt;&lt;progress max=&quot;34&quot; value=&quot;14&quot;&gt;&lt;/progress&gt;
  5394. &lt;/div&gt;
  5395. &lt;/div&gt;
  5396.  
  5397. &lt;p&gt;&lt;strong&gt;Why this goal?&lt;/strong&gt; This work continues our drive to improve support for async programming in Rust. In 2024H2 we stabilized async closures; explored the generator design space; and began work on the &lt;code&gt;dynosaur&lt;/code&gt; crate, an experimental proc-macro to provide dynamic dispatch for async functions in traits. In 2025H1 &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h1/async.html&quot;&gt;our plan&lt;/a&gt; is to deliver (1) improved support for async-fn-in-traits, completely subsuming the functionality of the &lt;a href=&quot;https://crates.io/crates/async-trait&quot;&gt;&lt;code&gt;async-trait&lt;/code&gt; crate&lt;/a&gt;; (2) progress towards sync and async generators, simplifying the creation of iterators and async data streams; (3) and improve the ergonomics of &lt;code&gt;Pin&lt;/code&gt;, making lower-level async coding more approachable. These items together start to unblock the creation of the next generation of async libraries in the wider ecosystem, as progress there has been blocked on a stable solution for async traits and streams.&lt;/p&gt;
  5398. &lt;p&gt;&lt;strong&gt;&lt;a href=&quot;https://github.com/rust-lang/rust-project-goals/issues/105#issuecomment-3081983979&quot;&gt;H1 Recap from @tmandry:&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;
  5399. &lt;p&gt;&lt;strong&gt;What went well&lt;/strong&gt;: This cycle we saw significant progress in a few areas:&lt;/p&gt;
  5400. &lt;ul&gt;
  5401. &lt;li&gt;We had productive conversations with the language team on generators, and landed an experimental implementation for a builtin &lt;code&gt;iter!&lt;/code&gt; macro that implements unpinned generators.&lt;/li&gt;
  5402. &lt;li&gt;We shipped async closures and the new lifetime capture rules as part of Rust 2024.&lt;/li&gt;
  5403. &lt;li&gt;We developed a proc macro, &lt;a href=&quot;https://crates.io/crates/dynosaur&quot;&gt;dynosaur&lt;/a&gt;, that can be used to support &lt;code&gt;async fn&lt;/code&gt; together with &lt;code&gt;dyn Trait&lt;/code&gt;.&lt;/li&gt;
  5404. &lt;li&gt;We landed an early-stage experiment to support &lt;code&gt;async Drop&lt;/code&gt; in the compiler.&lt;/li&gt;
  5405. &lt;li&gt;We landed an experimental implementation of autoreborrowing for pinned references, along with a number of other improvements for pin ergonomics.&lt;/li&gt;
  5406. &lt;/ul&gt;
  5407. &lt;p&gt;&lt;strong&gt;What didn't:&lt;/strong&gt; In some areas, we didn't make as much progress as we hoped. In retrospect, the scope of this goal was too large for one person to manage. With flagship project goals, there this a desire to paint a grand vision that I think would be better served by another mechanism without a time bound on it. I've been calling this a &quot;north star&quot;.&lt;/p&gt;
  5408. &lt;p&gt;In some cases, like RTN, progress has been by technical debt in the Rust compiler's type system. For that there is an ongoing project goal to replace the trait solver with a next-generation version. Finally, on the design front, progress is sometimes slowed by uncertainty and disagreement around the future of pinning in the Rust language.&lt;/p&gt;
  5409. &lt;p&gt;&lt;strong&gt;Looking forward:&lt;/strong&gt; My takeaway from this is that in the next project goals cycle, we should focus on answering more fundamental questions of Rust's evolution. These should reduce uncertainty and pave the way for us to unblock major features for async in future cycles. For example, how far we can push &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/pin-ergonomics.html&quot;&gt;pin ergonomics&lt;/a&gt;? What approach should we take for &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/in-place-initialization.html&quot;&gt;in-place initialization&lt;/a&gt;, and can it support &lt;code&gt;async fn&lt;/code&gt; in &lt;code&gt;dyn Trait&lt;/code&gt;? How will we support &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/evolving-traits.html&quot;&gt;evolving trait hierarchies&lt;/a&gt; in a general way that allows us to support the Tower &quot;middleware&quot; pattern with &lt;code&gt;async fn&lt;/code&gt;?&lt;/p&gt;
  5410. &lt;p&gt;I'm excited by the lineup of goals we have for this next cycle. See you on the other side!&lt;/p&gt;

  5427. &lt;p&gt;&lt;strong&gt;What went well&lt;/strong&gt;: This cycle we saw significant progress in a few areas:&lt;/p&gt;
  5428. &lt;ul&gt;
  5429. &lt;li&gt;We had productive conversations with the language team on generators, and landed an experimental implementation for a builtin &lt;code&gt;iter!&lt;/code&gt; macro that implements unpinned generators.&lt;/li&gt;

With flagship project goals, there this a desire to paint a grand vision that I think would be better served by another mechanism without a time bound on it.

  5449. &lt;p&gt;&lt;strong&gt;Why this goal?&lt;/strong&gt; May 15, 2025 marks the 10-year anniversary of Rust's 1.0 release; it also marks 10 years since the &lt;a href=&quot;https://internals.rust-lang.org/t/announcing-the-subteams/2042&quot;&gt;creation of the Rust subteams&lt;/a&gt;. At the time &lt;a href=&quot;http://web.archive.org/web/20150517235608/http://www.rust-lang.org/team.html&quot;&gt;there were 6 Rust teams with 24 people in total&lt;/a&gt;. There are now 57 teams with 166 people. In-person All Hands meetings are an effective way to help these maintainers get to know one another with high-bandwidth discussions. This year, the Rust Project will be coming together for &lt;a href=&quot;https://2025.rustweek.org&quot;&gt;RustWeek 2025&lt;/a&gt;, a joint event organized with &lt;a href=&quot;https://2025.rustweek.org/about/&quot;&gt;RustNL&lt;/a&gt;. Participating project teams will use the time to share knowledge, make plans, or just get to know one another better. One particular goal for the All Hands is reviewing a draft of the &lt;a href=&quot;https://blog.rust-lang.org/2025/08/05/july-project-goals-update/./rust-vision-doc.md&quot;&gt;Rust Vision Doc&lt;/a&gt;, a document that aims to take stock of where Rust is and lay out high-level goals for the next few years.&lt;/p&gt;

  5457. &lt;/div&gt;
  5458.  
  5459. &lt;p&gt;&lt;strong&gt;Why this goal?&lt;/strong&gt; This goal continues our work from 2024H2 in supporting the &lt;a href=&quot;https://rust-for-linux.com/&quot;&gt;experimental support for Rust development in the Linux kernel&lt;/a&gt;. Whereas in 2024H2 we were focused on stabilizing required language features, our focus in 2025H1 is stabilizing compiler flags and tooling options. We will (1) implement &lt;a href=&quot;https://github.com/rust-lang/rfcs/pull/3716&quot;&gt;RFC #3716&lt;/a&gt; which lays out a design for ABI-modifying flags; (2) take the first step towards stabilizing &lt;a href=&quot;https://doc.rust-lang.org/cargo/reference/unstable.html#build-std&quot;&gt;&lt;code&gt;build-std&lt;/code&gt;&lt;/a&gt; by &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h1/build-std.html&quot;&gt;creating a stable way to rebuild core with specific compiler options&lt;/a&gt;; (3) extending rustdoc, clippy, and the compiler with features that extract metadata for integration into other build systems (in this case, the kernel's build system).&lt;/p&gt;
  5460. &lt;p&gt;&lt;strong&gt;What has happened?&lt;/strong&gt;&lt;/p&gt;
  5461. &lt;ul&gt;
  5462. &lt;li&gt;&lt;a href=&quot;https://github.com/dingxiangfei2009&quot;&gt;Ding&lt;/a&gt; opened a &lt;a href=&quot;https://github.com/rust-lang/rust/pull/142518&quot;&gt;PR#142518&lt;/a&gt; that implements the &lt;a href=&quot;https://github.com/rust-lang/lang-team/issues/336&quot;&gt;in-place initialization experiment&lt;/a&gt;.&lt;/li&gt;
  5463. &lt;li&gt;Ding is working on an experimental implementation (&lt;a href=&quot;https://github.com/rust-lang/rust/pull/143527&quot;&gt;PR#143527&lt;/a&gt;) for &lt;code&gt;arbitrary_self_types&lt;/code&gt;.&lt;/li&gt;
  5464. &lt;li&gt;Ding opened a PR to Clang (a C frontend for LLVM): &lt;a href=&quot;https://github.com/llvm/llvm-project/pull/143424&quot;&gt;Queries on GCC-style inline assembly statements&lt;/a&gt; and got it merged.&lt;/li&gt;
  5465. &lt;li&gt;&lt;a href=&quot;https://github.com/ojeda&quot;&gt;@ojeda&lt;/a&gt; opened two Rust for Linux goals for the next period:

  5484. &lt;code&gt;arbitrary_self_types&lt;/code&gt;&lt;/h3&gt;
  5485. &lt;p&gt;Ding is working on an experimental implementation (&lt;a href=&quot;https://github.com/rust-lang/rust/pull/143527&quot;&gt;PR#143527&lt;/a&gt;).&lt;/p&gt;

  5487. Queries on GCC-style inline assembly statements:&lt;/h3&gt;
  5488. &lt;p&gt;Ding opened a PR to Clang (a C frontend for LLVM): &lt;a href=&quot;https://github.com/llvm/llvm-project/pull/143424&quot;&gt;https://github.com/llvm/llvm-project/pull/143424&lt;/a&gt; and got it merged.&lt;/p&gt;
  5489. &lt;p&gt;This is part of the LLVM/Clang issues the Rust for Linux project needs: &lt;a href=&quot;https://github.com/Rust-for-Linux/linux/issues/1132&quot;&gt;https://github.com/Rust-for-Linux/linux/issues/1132&lt;/a&gt;.&lt;/p&gt;

  5491. &lt;code&gt;-Zindirect-branch-cs-prefix&lt;/code&gt;:&lt;/h3&gt;
  5492. &lt;p&gt;We've discussed whether this needs to be a separate target feature vs. a modifier on the existing &lt;code&gt;retpoline&lt;/code&gt; one. Josh argued that since having this enabled without retpoline doesn't make sense, it should be a modifier. On the other hand, Miguel mentioned that it would be clearer on the user's side (easier to map the names from GCC and Clang to &lt;code&gt;rustc&lt;/code&gt; when they're the same and see that we're enabling the same thing in Rust and Linux kernel's &lt;code&gt;Makefiles&lt;/code&gt;).&lt;/p&gt;
  5493. &lt;p&gt;It seems that &lt;code&gt;-Cmin-function-alignment&lt;/code&gt; will be another similar case.&lt;/p&gt;
  5494. &lt;p&gt;Ultimately, this is a compiler question and should be resolved here: &lt;a href=&quot;https://github.com/rust-lang/rust/pull/140740&quot;&gt;https://github.com/rust-lang/rust/pull/140740&lt;/a&gt;&lt;/p&gt;
  5495. &lt;p&gt;The Rust for Linux team &lt;a href=&quot;https://github.com/rust-lang/rust/pull/140740#issuecomment-3050376762&quot;&gt;was asked&lt;/a&gt; to submit a new &lt;a href=&quot;https://forge.rust-lang.org/compiler/proposals-and-stabilization.html#how-do-i-submit-an-mcp&quot;&gt;MCP (Major Change Proposal)&lt;/a&gt; for the &lt;code&gt;-Zindirect-branch-cs-prefix&lt;/code&gt; flag. @ojeda opened it here: &lt;a href=&quot;https://github.com/rust-lang/compiler-team/issues/899&quot;&gt;https://github.com/rust-lang/compiler-team/issues/899&lt;/a&gt; and it's now been accepted.&lt;/p&gt;

  5501. &lt;/ul&gt;
  5502. &lt;p&gt;In light of the newly-proposed &lt;code&gt;#[sanitize(xyz = &quot;on|off&quot;)]&lt;/code&gt; syntax, we've discussed whether it makes sense to add a shorthand to enable/disable all of them at once (e.g. &lt;code&gt;#[sanitize(all = &quot;on|off&quot;)]&lt;/code&gt;). The experience from the field suggests that this is rarely something people do.&lt;/p&gt;
  5503. &lt;p&gt;We've also discussed what values should the options have (e.g. &lt;code&gt;&quot;yes&quot;&lt;/code&gt;/&lt;code&gt;&quot;no&quot;&lt;/code&gt; vs. &lt;code&gt;&quot;on&quot;&lt;/code&gt;/&lt;code&gt;&quot;off&quot;&lt;/code&gt; or &lt;code&gt;true&lt;/code&gt;/&lt;code&gt;false&lt;/code&gt;). No strong preferences, but in case of an error, the compiler should suggest the correct value to use.&lt;/p&gt;
  5504. &lt;p&gt;P.S.: There will be a Lang design meeting regarding in-place initialization on Wednesday 2025-07-30: https://github.com/rust-lang/lang-team/issues/332.&lt;/p&gt;

  5634. &lt;p&gt;Not much to say since the last update- I have been focused on other areas of const generics and I believe camelid has been relatively busy with other things too. I intend for the next const generics project goal to be more broadly scoped than just &lt;code&gt;min_generic_const_args&lt;/code&gt; so that other const generics work can be given a summary here :)&lt;/p&gt;

  5644. &lt;ul&gt;
  5645. &lt;li&gt;Discussed the latest round of feedback on the pre-RFC, the most significant of which is that the scope of the RFC is almost certainly too large for an MVP.&lt;/li&gt;
  5646. &lt;li&gt;@davidtwco presented a reformulation of the plan which focuses on the core components of build-std and leaves more features for future extensions after a minimal MVP:
  5647. &lt;ul&gt;
  5648. &lt;li&gt;Stage 1a: Introduce manual controls for enabling the build-std behavior in Cargo.&lt;/li&gt;
  5649. &lt;li&gt;Stage 1b: Introduce Cargo syntax to declare explicit dependencies on core, alloc and std crates.
  5650. &lt;ul&gt;
  5651. &lt;li&gt;This stage enables the use of Tier 3 targets on stable Rust and allows the ecosystem to start transitioning to explicit dependencies on the standard library.&lt;/li&gt;
  5652. &lt;li&gt;This stage would be considered the minimal MVP.&lt;/li&gt;
  5653. &lt;/ul&gt;
  5654. &lt;/li&gt;
  5655. &lt;li&gt;Stage 2: Teach Cargo to build std with different codegen/target modifier options.
  5656. &lt;ul&gt;
  5657. &lt;li&gt;This stage allows the standard library to be compiled with custom codegen options.&lt;/li&gt;
  5658. &lt;/ul&gt;
  5659. &lt;/li&gt;
  5660. &lt;li&gt;Stage 3: Enable automatic standard library rebuilds.
  5661. &lt;ul&gt;
  5662. &lt;li&gt;This stage focuses on making build-std behave ergonomically and naturally without users having to manually ask for the standard library to be built.&lt;/li&gt;
  5663. &lt;/ul&gt;
  5664. &lt;/li&gt;
  5665. &lt;/ul&gt;
  5666. &lt;/li&gt;
  5667. &lt;li&gt;General consensus was reached that this plan feels viable. @davidtwco will write the Stage 1a/b RFC.&lt;/li&gt;
  5668. &lt;li&gt;Submitted a &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/build-std.html&quot;&gt;2025H2 goal proposal&lt;/a&gt;&lt;/li&gt;

  5724. &lt;p&gt;Belated update for May and June: RustWeek was &lt;em&gt;extremely&lt;/em&gt; productive! It was great to sit down in a room with all the stakeholders and talk about what it would take to get cross-crate linting working reliably at scale.&lt;/p&gt;
  5725. &lt;p&gt;As a result of this work we identified a lot of previously-unknown blockers, as well as some paths forward. More work remains, but it's nice that we now have a much better idea of what that work should look like.&lt;/p&gt;
  5726. &lt;p&gt;TL;DR:&lt;/p&gt;
  5727. &lt;ul&gt;
  5728. &lt;li&gt;&lt;code&gt;?Sized&lt;/code&gt; linting is blocked since it &lt;a href=&quot;https://github.com/rust-lang/rust/issues/143197&quot;&gt;requires additional data in rustdoc JSON&lt;/a&gt;.
  5729. &lt;ul&gt;
  5730. &lt;li&gt;Currently we get information on the &lt;em&gt;syntactic&lt;/em&gt; presence of &lt;code&gt;?Sized&lt;/code&gt;. But another bound might be implying &lt;code&gt;Sized&lt;/code&gt;, which makes &lt;code&gt;?Sized&lt;/code&gt; not true overall.&lt;/li&gt;
  5731. &lt;li&gt;Failing to account for this would mean we get both false negatives and false positives. This is effectively a dual of the the &quot;implied bounds&quot; issue in the previous post.&lt;/li&gt;
  5732. &lt;/ul&gt;
  5733. &lt;/li&gt;
  5734. &lt;li&gt;Cross-crate linting has had some positive movement, and some additional blockers identified.
  5735. &lt;ul&gt;
  5736. &lt;li&gt;docs.rs has begun hosting rustdoc JSON, allowing us to use it as a cache to avoid rebuilding rustdoc JSON in cross-crate linting scenarios where those builds could get expensive.&lt;/li&gt;
  5737. &lt;li&gt;We need a way to determine which features in dependencies are active (recursively) given a set of features active in the the top crate, so we know how to generate accurate rustdoc JSON. That information is not currently available via the lockfile or any cargo interface.&lt;/li&gt;
  5738. &lt;li&gt;We need to work with the rustdoc and cargo teams to make it possible to use rmeta files to correctly combine data across crates. This has many moving parts and will take time to get right, but based on in-person conversations at RustWeek we all agreed was the best and most reliable path forward.&lt;/li&gt;
  5739. &lt;/ul&gt;
  5740. &lt;/li&gt;
  5741. &lt;li&gt;Other improvements to &lt;code&gt;cargo-semver-checks&lt;/code&gt; are ongoing: a full set of &lt;code&gt;#[target_feature]&lt;/code&gt; lints ships in the next release, and two folks participating in Google Summer of Code have begun contributing to &lt;code&gt;cargo-semver-checks&lt;/code&gt; already!&lt;/li&gt;
  5742. &lt;/ul&gt;
  5743. &lt;p&gt;While the targets for the 2025H1 goals proved a bit too ambitious to hit in this timeline, I'm looking forward to continuing my work on the goal in the 2025H2 period!&lt;/p&gt;

  5785. &lt;li&gt;@joshtriplett, @eholk, and @vincenzopalazzo did some successful group-spelunking into the implementation of macros in rustc.&lt;/li&gt;
  5786. &lt;li&gt;@joshtriplett &lt;a href=&quot;https://github.com/rust-lang/rust/pull/143070/&quot;&gt;rewrote the &lt;code&gt;macro_rules!&lt;/code&gt; parser&lt;/a&gt;, which enabled future extensibility &lt;em&gt;and&lt;/em&gt; resulted in better error messages.

  5799. &lt;li&gt;@joshtriplett authored RFCs for both &lt;a href=&quot;https://github.com/rust-lang/rfcs/pull/3697&quot;&gt;attribute macros&lt;/a&gt; and &lt;a href=&quot;https://github.com/rust-lang/rfcs/pull/3698&quot;&gt;derive macros&lt;/a&gt;. Both were accepted and merged.&lt;/li&gt;
  5800. &lt;li&gt;@joshtriplett, @eholk, and @vincenzopalazzo did some successful group-spelunking into the implementation of macros in rustc.&lt;/li&gt;
  5801. &lt;li&gt;@joshtriplett &lt;a href=&quot;https://github.com/rust-lang/rust/pull/143070/&quot;&gt;rewrote the &lt;code&gt;macro_rules!&lt;/code&gt; parser&lt;/a&gt;, which enabled future extensibility &lt;em&gt;and&lt;/em&gt; resulted in better error messages. This then enabled several follow-up refactors and simplifications.&lt;/li&gt;
  5802. &lt;li&gt;@joshtriplett wrote a PR implementing attribute macros (review in progress).&lt;/li&gt;

  5820. &lt;p&gt;&lt;strong&gt;Recap&lt;/strong&gt; by @tmandry:&lt;/p&gt;
  5821. &lt;p&gt;This project goals cycle was important for C++ interop. With the language team we &lt;a href=&quot;https://hackmd.io/2Ar_7CNoRkeXk1AARyOL7A?view&quot;&gt;established that we should evolve Rust to enable a first-class C++ interop story&lt;/a&gt;, making rich and automatic bindings possible between the two languages. At the Rust All Hands, &lt;a href=&quot;https://github.com/rust-lang/rust-project-goals/issues/253#issuecomment-2901991797&quot;&gt;people from across the industry met&lt;/a&gt; to describe their needs to each other, what is working for them, and what isn't. This process of discovery has led to a lot of insight into where we can make progress now and ideas for what it will take to really &quot;solve&quot; interop.&lt;/p&gt;
  5822. &lt;p&gt;One thing I think we can say with certainty is that interop is a vast problem space, and that any two groups who want interop are very likely to have different specific needs. I'm excited about the project goal proposal by @baumanj to begin &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/interop-problem-map.html&quot;&gt;mapping this problem space&lt;/a&gt; out in the open, so that as we refer to problems we can better understand where our needs overlap and diverge.&lt;/p&gt;
  5823. &lt;p&gt;Despite the diversity of needs, we've noticed that there is quite a bit of overlap when it comes to language evolution. This includes many features requested by Rust for Linux, a flagship customer of the Rust Project. In retrospect, this is not surprising: Rust for Linux needs fine-grained interop with C APIs, which is roughly a subset of the needs for interop with C++ APIs. Often the need runs deeper than interop, and is more about supporting patterns in Rust that existing systems languages already support as a first-class feature.&lt;/p&gt;
  5824. &lt;p&gt;I'm looking forward to tackling areas where we can &quot;extend the fundamentals&quot; of Rust in a way that makes these, and other use cases, possible. This includes H2 project goal proposals like &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/pin-ergonomics.html&quot;&gt;pin ergonomics&lt;/a&gt;, &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/autoreborrow-traits.html&quot;&gt;reborrowing&lt;/a&gt;, &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/field-projections.html&quot;&gt;field projections&lt;/a&gt;, and &lt;a href=&quot;https://rust-lang.github.io/rust-project-goals/2025h2/in-place-initialization.html&quot;&gt;in-place initialization&lt;/a&gt;.&lt;/p&gt;

  5833.  
  5834. &lt;p&gt;Ahead of the all hands, @cramertj and @tmandry collaborated on a prototype called &lt;a href=&quot;https://github.com/cramertj/rust/tree/ecdysis&quot;&gt;ecdysis&lt;/a&gt; that explored the viability of instantiating types &quot;on-demand&quot; in the Rust compiler. These types are intended to look like C++ template instantiations. The prototype was a success in that it made the direction look viable and also surfaced some foundational work that needs to happen in the compiler first. That said, continuing to pursue it is not the highest priority for either of us at the moment.&lt;/p&gt;

  5876. &lt;p&gt;The last update for this project-goal period! I have continued to work on the gpu support, while our two Rust/LLVM autodiff gsoc students made great progress with their corresponding projects.&lt;/p&gt;
  5877. &lt;p&gt;&lt;strong&gt;Key developments:&lt;/strong&gt;&lt;/p&gt;
  5878. &lt;ol&gt;
  5879. &lt;li&gt;
  5880. &lt;p&gt;My memory-movement PR got reviewed and after a few iterations landed in nightly. That means you now don't even have to build your own rustc to move data to and from a GPU (with the limitations mentioned in my previous post). As part of my PR, I also updated the rustc-dev-guide: &lt;a href=&quot;https://rustc-dev-guide.rust-lang.org/offload/installation.html&quot;&gt;https://rustc-dev-guide.rust-lang.org/offload/installation.html&lt;/a&gt;.&lt;/p&gt;
  5881. &lt;/li&gt;
  5882. &lt;li&gt;
  5883. &lt;p&gt;Now that the host (CPU) code landed, I looked into compiling rust kernels to GPUs. When experimenting with the amdgcn target for rustc I noticed a regression, due to which all examples for that target failed. I submitted a small patch to fix it. It landed a few days ago, and prevents rustc from generating f128 types on AMD GPUs: &lt;a href=&quot;https://github.com/rust-lang/rust/pull/144383&quot;&gt;https://github.com/rust-lang/rust/pull/144383&lt;/a&gt;.&lt;/p&gt;
  5884. &lt;/li&gt;
  5885. &lt;li&gt;
  5886. &lt;p&gt;I looked into HIP and OpenMP (managed/kernel-mode) examples to see what's needed to launch the kernels. I should already have most of the code upstream, since it landed as part of my host PR, so I think I should soon be able to add the remaining glue code to start running Rust code on GPUs. &lt;a href=&quot;https://github.com/rust-lang/rust/pull/142696&quot;&gt;https://github.com/rust-lang/rust/pull/142696&lt;/a&gt;.&lt;/p&gt;
  5887. &lt;/li&gt;
  5888. &lt;li&gt;
  5889. &lt;p&gt;The main PR of @KMJ-007 is up, to start generating typetrees for Enzyme, the backend of our std::autodiff module. Enzyme sometimes wants more information about a type than it can get from LLVM, so it either needs to deduce it (slow), or it will fail to compile (bad). In the future we hope to lower MIR information to Enzyme, and this is the first step for it. I just submitted the first round of reviews: &lt;a href=&quot;https://github.com/rust-lang/rust/pull/142640&quot;&gt;https://github.com/rust-lang/rust/pull/142640&lt;/a&gt;&lt;/p&gt;
  5890. &lt;/li&gt;
  5891. &lt;li&gt;
  5892. &lt;p&gt;The main PR of @Sa4dUs is up, it replaces my historically grown middle-end with a proper rustc-autodiff-intrinsic. This allows us to remove a few hacks and thus makes it easier to maintain. It will also handle more corner-cases, and reduces the amount of autodiff related code in rustc by ~400 lines. I also gave it a first review pass.&lt;/p&gt;
  5893. &lt;/li&gt;
  5894. &lt;/ol&gt;
  5895. &lt;p&gt;I also submitted an updated project-goal to finish the &lt;code&gt;std::offload&lt;/code&gt; module, to the point where we can write an interesting amount of kernels in pure (nightly) Rust and launch them to GPUs. All new project goals are supposed to have &quot;champions&quot; from the teams they are related to, which in the case of my autodiff/batching/offload work would be t-compiler and t-lang (see &lt;a href=&quot;https://blog.rust-lang.org/inside-rust/2025/06/23/project-goals-2025h2-call-for-submissions/&quot;&gt;Niko's blog post for more details&lt;/a&gt;). Since I joined the compiler team a while ago I can now champion for it myself on the compiler side, and @traviscross volunteered to continue the support on the language side, thank you!&lt;/p&gt;

  5938. &lt;p&gt;My time at Amazon is coming to an end. They supported the very successful effort with the 2024h2 goal, and encouraged me to propose the 2025h1 goal that is now wrapping up. Unfortunately other work efforts led to the very limited progress on the 2025h1 goal. I do not know what comes next, but it definitely involves taking time to relax and recover. Recovering involves rediscovering the joy in the work that I love. And, I have a deep passion for this problem. I hope to make some time to work on this. But, relaxing requires reducing the commitments I have made to others and the associated stress. So I will not promise progress, nor will I renew the goal for 2025h2.&lt;/p&gt;

  5951. &lt;p&gt;As the 2025 H1 period is coming to an end and we're focusing on the goals for the second half of the year, we will close this issue by the end of this month (July 2025).&lt;/p&gt;
  5952. &lt;p&gt;If you or someone else out there is working on this and has updates to share, please add them as a comment here by 2025-07-29 so they can be included in the final blog post.&lt;/p&gt;
  5953. &lt;p&gt;Even after the issue is closed, the work here &lt;em&gt;can&lt;/em&gt; be picked up -- we'll just no longer track it as part of the 2025H1 goals effort.&lt;/p&gt;

  6017. &lt;p&gt;Chiming in for @epage here since further progress is still blocked on the compiler implementation. Unfortunately things have been moving more slowly than I had initially hoped. We have been doing some refactoring (https://github.com/rust-lang/rust/pull/142547 and https://github.com/rust-lang/rust/pull/144131) that allow us to introduce a new &lt;code&gt;Scope&lt;/code&gt; for namespaced crates inside name resolution. There's a draft PR (https://github.com/rust-lang/rust/pull/140271) that should be straightforward to adapt to the refactoring.&lt;/p&gt;

  6034. &lt;p&gt;Implementation remains in progress; I'll be able to land a couple PRs soon getting it largely implemented. Progress was slower than expected due to me having a fair amount going on. As I still very much want this feature, I will continue work on it even with the goal having formally lapsed.&lt;/p&gt;
  6035. &lt;p&gt;Additionally, I think that after it's fully implemented it may be feasible to leverage the crate-local knowledge of &lt;code&gt;impl&lt;/code&gt; restrictions to optimize &lt;code&gt;dyn&lt;/code&gt; in an &lt;code&gt;enum_dispatch&lt;/code&gt;-like manner. I haven't investigated the feasibility of that in the compiler — it's merely a suspicion.&lt;/p&gt;

  6120. &lt;blockquote&gt;
  6121.  
  6122. &lt;p&gt;We - or well, overwhelmingly @compiler-errors - continued to make performance improvements to the new solver over the last month: https://github.com/rust-lang/rust/pull/142802 https://github.com/rust-lang/rust/pull/142732 https://github.com/rust-lang/rust/pull/142317 https://github.com/rust-lang/rust/pull/142316 https://github.com/rust-lang/rust/pull/142223 https://github.com/rust-lang/rust/pull/142090 https://github.com/rust-lang/rust/pull/142088 https://github.com/rust-lang/rust/pull/142085 https://github.com/rust-lang/rust/pull/141927 https://github.com/rust-lang/rust/pull/141581 https://github.com/rust-lang/rust/pull/141451. &lt;code&gt;nalgebra&lt;/code&gt; is currently 70% slower than with the old solver implementation and we seem to be about 30-50% slower in most &lt;em&gt;normal&lt;/em&gt; crates.&lt;/p&gt;
  6123. &lt;p&gt;I've been working on strengthening the search graph to avoid the hang in rayon and https://github.com/rust-lang/trait-system-refactor-initiative/issues/210 in a principled way. This has been more challenging than expected and will take at least another week to get done.&lt;/p&gt;
  6124.  
  6125. &lt;/blockquote&gt;
  6126.  
  6127. &lt;p&gt;&lt;a href=&quot;https://github.com/rust-lang/rust-project-goals/issues/113#issuecomment-3131816067&quot;&gt;Comment by @lcnr posted on 2025-07-29:&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;
  6128. &lt;blockquote&gt;
  6129.  
  6130. &lt;p&gt;Since the last update @compiler-errors landed two additional perf optimizations: https://github.com/rust-lang/rust/pull/143500 https://github.com/rust-lang/rust/pull/143309.&lt;/p&gt;
  6131. &lt;p&gt;I am still working on the hang in rayon and https://github.com/rust-lang/trait-system-refactor-initiative/issues/210. I've ended up having to change the invariants of the type system to support a fast paths based on structural identity, e.g. quickly proving &lt;code&gt;T: Trait&amp;lt;'a&amp;gt;&lt;/code&gt; via a &lt;code&gt;T: Trait&amp;lt;'a&amp;gt;&lt;/code&gt; where-bound, in https://github.com/rust-lang/rust/pull/144405. Changing this invariant requires some additional work in HIR typeck, so I am currently reducing the perf impact of that change.&lt;/p&gt;
  6132. &lt;p&gt;With this I can then land the actual fast paths which fix both rayon and similar hangs due to a large number of where-bounds. This should also be done soon. I will then go back to implement the new opaque type handling approach as that's the only remaining issue before we can call for testing.&lt;/p&gt;
  6133.

  6169. &lt;p&gt;&lt;strong&gt;Blockers:&lt;/strong&gt; question of how to insert a check if we already observe UB (e.g. the enum is only represented by an i1 in LLVM IR). This is to be addressed by the next project goal: https://rust-lang.github.io/rust-project-goals/2025h2/comprehensive-niche-checks.html.&lt;/p&gt;

  6180. &lt;p&gt;&lt;strong&gt;Final monthly update!&lt;/strong&gt;&lt;/p&gt;
  6181. &lt;ul&gt;
  6182. &lt;li&gt;
  6183. &lt;p&gt;Even more optimizations have been achieved on the documentation lints front. &lt;a href=&quot;https://github.com/rust-lang/rust-clippy/pull/15030&quot;&gt;https://github.com/rust-lang/rust-clippy/pull/15030&lt;/a&gt; (-6.7% on &lt;code&gt;bumpalo&lt;/code&gt;).&lt;/p&gt;
  6184. &lt;/li&gt;
  6185. &lt;li&gt;
  6186. &lt;p&gt;The 3rd heaviest function was optimized away by 99.75%, along with the &lt;a href=&quot;https://rust-lang.github.io/rust-clippy/master/index.html#strlen_on_c_strings&quot;&gt;&lt;code&gt;strlen_on_c_strings&lt;/code&gt;&lt;/a&gt; lint. This gives us about a 15% optimization on &lt;code&gt;tokio&lt;/code&gt;. &lt;a href=&quot;https://github.com/rust-lang/rust-clippy/pull/15043&quot;&gt;https://github.com/rust-lang/rust-clippy/pull/15043&lt;/a&gt;.&lt;/p&gt;
  6187. &lt;/li&gt;
  6188. &lt;li&gt;
  6189. &lt;p&gt;As a minor improvement, we now instantiate a lot less types on &lt;code&gt;unit_return_expecting_ord&lt;/code&gt; (89% less calls in some benchmarks). This saves us a lot of locks on the type interner.&lt;/p&gt;
  6190. &lt;/li&gt;
  6191. &lt;/ul&gt;
  6192. &lt;p&gt;As a final update to the project goal, I'd like to say a little bit more:&lt;/p&gt;
  6193. &lt;p&gt;I'm very happy with how this project goal has turned out. We've seen improvements in the 35-60% range for your real world projects and while I couldn't deliver the two objectives the project goal promised because of an excess in ambition, I still don't think that these are too far-fetched by any means.&lt;/p&gt;
  6194. &lt;p&gt;As some specific examples, you can now witness a &lt;strong&gt;38%&lt;/strong&gt; performance improvements in analyzing Cargo, and a &lt;strong&gt;61%&lt;/strong&gt; in analyzing Tokio!&lt;/p&gt;
  6195. &lt;p&gt;Much more to come, and thanks for sticking by while we make Clippy a better project, with better developer experience.
  6196. Have a great week, and I hope that you can enjoy all the performance improvements that we've delivered across this project goal.&lt;/p&gt;

  6205. &lt;p&gt;&lt;strong&gt;Final monthly update!&lt;/strong&gt;&lt;/p&gt;
  6206. &lt;ul&gt;
  6207. &lt;li&gt;
  6208. &lt;p&gt;Even more optimizations have been achieved on the documentation lints front. https://github.com/rust-lang/rust-clippy/pull/15030. (-6.7% on &lt;code&gt;bumpalo&lt;/code&gt;).&lt;/p&gt;
  6209. &lt;/li&gt;
  6210. &lt;li&gt;
  6211. &lt;p&gt;The 3rd heaviest function was optimized away by 99.75%, along with the &lt;a href=&quot;https://rust-lang.github.io/rust-clippy/master/index.html#strlen_on_c_strings&quot;&gt;&lt;code&gt;strlen_on_c_strings&lt;/code&gt;&lt;/a&gt; lint. This gives us about a 15% optimization on &lt;code&gt;tokio&lt;/code&gt;. https://github.com/rust-lang/rust-clippy/pull/15043&lt;/p&gt;
  6212. &lt;/li&gt;
  6213. &lt;li&gt;
  6214. &lt;p&gt;As a minor improvement, we now instantiate a lot less types on &lt;code&gt;unit_return_expecting_ord&lt;/code&gt; (89% less calls in some benchmarks). This saves us a lot of locks on the type interner.&lt;/p&gt;
  6215. &lt;/li&gt;
  6216. &lt;/ul&gt;
  6217. &lt;p&gt;As a final update to the project goal, I'd like to say a little bit more:&lt;/p&gt;
  6218. &lt;p&gt;I'm very happy with how this project goal has turned out. We've seen improvements in the 35-60% range for your real world projects and while I couldn't deliver the two objectives the project goal promised because of an excess in ambition, I still don't think that these are too far-fetched by any means.&lt;/p&gt;
  6219. &lt;p&gt;As some specific examples, you can now witness a &lt;strong&gt;38%&lt;/strong&gt; performance improvements in analyzing Cargo, and a &lt;strong&gt;61%&lt;/strong&gt; in analyzing Tokio!&lt;/p&gt;
  6220. &lt;p&gt;Much more to come, and thanks for sticking by while we make Clippy a better project, with better developer experience.
  6221. Have a great week, and I hope that you can enjoy all the performance improvements that we've delivered across this project goal.&lt;/p&gt;

  6239. &lt;p&gt;@fee1-dead has also updated the syntax to allow for &lt;code&gt;const trait Trait {}&lt;/code&gt; declarations instead of &lt;code&gt;#[const_trait] trait Trait {}&lt;/code&gt;.&lt;/p&gt;
  6240. &lt;p&gt;Thanks y'all for moving this feature along!&lt;/p&gt;
  6241. &lt;p&gt;We have encountered few issues, but there is one major one:&lt;/p&gt;
  6242. &lt;p&gt;without &lt;code&gt;dyn [const] Trait&lt;/code&gt; support we cannot turn any of the &lt;code&gt;core::fmt&lt;/code&gt; traits const in a usable way. This in turn makes things like &lt;code&gt;Result::unwrap&lt;/code&gt; not usable in const contexts without using &lt;code&gt;const_eval_select&lt;/code&gt; to not actually perform any formatting within const contexts.&lt;/p&gt;
  6243. &lt;p&gt;It is my belief that now would be a good time to call for testing to get community input on the current syntax and behaviour.&lt;/p&gt;

  6252. &lt;p&gt;The current proposal is &lt;code&gt;[const] Trait&lt;/code&gt; syntax for bounds, &lt;code&gt;impl const Trait for Type&lt;/code&gt; syntax for impls and &lt;code&gt;const Trait&lt;/code&gt; for trait declarations. No annotations on methods in traits or impls required, but all implied from the trait or impl.&lt;/p&gt;

  6321. &lt;p&gt;The FLS is now an independent repository within the Rust Project, not relying on imported Ferrocene packages for building (we have brought them in locally). A version of the FLS has been published at &lt;a href=&quot;https://rust-lang.github.io/fls&quot;&gt;https://rust-lang.github.io/fls&lt;/a&gt; using the new build process. The content changes were mostly non-normative at this point, but we have officially published the first rust-lang owned release of the FLS.&lt;/p&gt;
  6322. &lt;p&gt;Next steps: Continue adding/modifying appropriate content for the FLS moving forward. Determine any potential H2 2025 spec-related project goals.&lt;/p&gt;

  6431. &lt;li&gt;the drop-liveness dataflow &lt;a href=&quot;https://github.com/rust-lang/rust/pull/141667&quot;&gt;optimization&lt;/a&gt; landed, and &lt;a href=&quot;https://github.com/rust-lang/rust/pull/142471&quot;&gt;I've also changed&lt;/a&gt; the bitset used in the loans-in-scope computation to better support the sparser cases with a lot of loans that we see in a handful of benchmarks (and we could tune that cutoff if we wanted to, it's currently around 2K by default in the &lt;code&gt;MixedBitSet&lt;/code&gt; implementation IIRC).&lt;/li&gt;
  6432. &lt;li&gt;the rustc-perf benchmarks we have mostly exercise the move/init dataflow parts of borrow-checking, so I've created a stress test that puts emphasis on the loans-in-scope computation in particular, and have started gathering stats on crates.io code to have realistic examples. There are juicy functions in there, where one of the dataflow passes can take 40 seconds.&lt;/li&gt;
  6433. &lt;li&gt;I reworked the in-tree analysis to what should be close to a &quot;polonius alpha&quot; version of the analysis -- modulo a few loose ends that still need to be fixed -- and did some perf runs and a few crater runs with it enabled by default: nothing exploded. We know that this version based on reachability fixes fewer issues than a full version handling 100% of the flow-sensitivity problem -- like the datalog implementation did, albeit too slowly -- but is &lt;em&gt;actionable&lt;/em&gt; and meaningful progress: it fixes many cases of NLL problem 3. We're also reasonably confident that we can make a production-ready version of this alpha algorithm, and in this project goal period we have identified the areas where improvements can be made to gradually improve expressiveness, and that we wish to explore later.&lt;/li&gt;
  6434. &lt;li&gt;I also discovered a couple of failing examples with the new edition edition 2024 capture rules, and generally need to take care of member constraints, so it's not unexpected. Another small signal to improve test coverage, but not specific to borrowck: it's for all tests and editions in general, as seen in &lt;a href=&quot;https://github.com/rust-lang/compiler-team/issues/861&quot;&gt;MCP #861&lt;/a&gt;.&lt;/li&gt;
  6435. &lt;li&gt;I've opened &lt;a href=&quot;https://github.com/rust-lang/rust/pull/143093&quot;&gt;PR #143093&lt;/a&gt; to land this polonius alpha analysis, and after looking into fixing member constraints, it should be the behavioral basis of what we hope to stabilize in the future, once it's more suited to production (e.g. better perf, better test coverage, more edge cases analyses, formalism) be it by incremental improvements, or via a different rewritten version of this algorithm -- with modifications to NLLs to make the interactions lazier/on-demand, so that we don't run a more expensive analysis if we don't need to.&lt;/li&gt;
  6436. &lt;/ul&gt;
  6437. &lt;p&gt;In the future, hopefully for a h2 project goal, I plan to do that work towards stabilizing this alpha version of the analysis.&lt;/p&gt;

  6467. &lt;p&gt;Hello All -&lt;/p&gt;
  6468. &lt;p&gt;Following is a status update and breakdown on where things currently stand for the MVP implementation of TUF and the choices we’ve landed at so far with the discussion via this goal. At the end of this update is a briefer list-form of this update.&lt;/p&gt;
  6469. &lt;p&gt;In summary, we have landed at moving forward with a TAP-16 Merkle Tree implementation of TUF for crates.io, with technical choices pending on the best balance and optimization for our specific performance needs. We are still currently on track to have a MVP public implementation by the end of July of this implementation, which optimizations will be tested against. This includes:&lt;/p&gt;
  6470. &lt;ul&gt;
  6471. &lt;li&gt;Test repositories and tooling for rustup, releases and crates.io&lt;/li&gt;
  6472. &lt;li&gt;Temporary repository tooling for updates (We are currently outside these services, and so updates occur via periodic checks)&lt;/li&gt;
  6473. &lt;li&gt;An out-of-band index copy for crates.io for in-line signing testing&lt;/li&gt;
  6474. &lt;li&gt;cargo-signing subcommand tooling for end-user functionality (TUF updates, validation and downloading)&lt;/li&gt;
  6475. &lt;/ul&gt;
  6476. &lt;p&gt;We still have open questions for the specific approach of the Merkle tree, which is continuing into H2. We have also reached an acceptable consensus with the infrastructure team for deployment planning.&lt;/p&gt;
  6477. &lt;p&gt;TUF Implementation&lt;/p&gt;
  6478. &lt;p&gt;During H1, we experimented with 4 implementations of TUF: To-spec, Hashed Bins, Succinct Hashed Bins, and TUF TAP-16 Merkle Trees. Hashed Bins &amp;amp; Succinct Hashed Bins are the current approaches being experimented with in the Python community, and we wanted to see how that would align with our growth and bandwidth requirements. After experimenting, we found the linear growth models to still be unacceptable, thus landing at the Merkle Tree implementation. This still comes at a round-trip increase cost, however, and for H2 we are now experimenting with how to implement the Merkle tree to reduce round-trips - via balancing, implementation details and tree slicing - or a combination of the three..&lt;/p&gt;
  6479. &lt;p&gt;Quorum &amp;amp; Roles&lt;/p&gt;
  6480. &lt;p&gt;On the higher level grounds of quorums and infrastructure, through discussions, we have come to a consensus on maintaining a top-level quorum, but removing intermediate levels for simplicity. The root quorum shall be the Infrastructure team for initial deployment; roles under this quorum will be nightly, releases, rustup and crates.io; each one of these keys will be a single live key which resides in KMS. We will leverage KMS API’s to perform live signing for all actions of those roles (new releases and crates). The hierarchy initially proposed in the RFC will be removed in favor of this approach.&lt;/p&gt;
  6481. &lt;p&gt;The root quorum will manage the roles via tuf-on-ci on a github repository, while actual signing actions using the live keys will all occur via local tooling in their CI.&lt;/p&gt;
  6482. &lt;p&gt;Choices Made&lt;/p&gt;
  6483. &lt;p&gt;Listed here the choices made as a part of this goal:&lt;/p&gt;
  6484. &lt;ul&gt;
  6485. &lt;li&gt;Initial root quorum will be the infrastructure team with a 3-member threshold. This can be rotated or grown at any time by that team in the future.&lt;/li&gt;
  6486. &lt;li&gt;Role keys will live in KMS and be used in the appropriate CI/infrastructure of those teams (Infra for nightly, releases and rustup; the crates.io team for crates). This will be managed via IAM access to the KMS.&lt;/li&gt;
  6487. &lt;li&gt;TAP-16 Merkle Tree implementation of TUF was chosen. Other methods linear+ growth models were unacceptable. We still have open questions to resolve around bandwidth vs. round-trips&lt;/li&gt;
  6488. &lt;li&gt;tuf-on-ci will only be used for the root quorum and role changes, to leverage PR-workflows for easy management.&lt;/li&gt;
  6489. &lt;li&gt;The source-of-truth TUF repository will live in an S3 bucket.&lt;/li&gt;
  6490. &lt;li&gt;We will rely on cloudtrail for audit logging of KMS and work to make those logs available for transparency&lt;/li&gt;
  6491. &lt;/ul&gt;
  6492. &lt;p&gt;Next Steps&lt;/p&gt;
  6493. &lt;ul&gt;
  6494. &lt;li&gt;A public MVP will go live at the end of July / August, and live changes/tests will be made of the Merkle tree implementation there.&lt;/li&gt;
  6495. &lt;li&gt;We still need to determine the appropriate trade off for round trips vs. bandwidth for the Merkle Tree. We are collecting more granular logs from the sparse index and crates.io index as a whole to accomplish this. Crate downloads vs. updates are very unbalanced, and we expect to get significant reductions of both by appropriately balancing the tree.&lt;/li&gt;
  6496. &lt;li&gt;Work needs to start on beginning to stand up infrastructure in the project to house this in the simpleinfra repository. Besides the raw infrastructure, this needs to be tooling for the initial creation ceremony.&lt;/li&gt;
  6497. &lt;li&gt;We’ve begun thinking about what different mirroring strategies look like when utilizing TUF, to make sure we consider those when deploying this. The MVP provides basic validation of any mirror, but how can mirroring and fallbacks possibly be integrated?&lt;/li&gt;
  6498. &lt;/ul&gt;

  6549. &lt;ul&gt;
  6550. &lt;li&gt;rust-lang/rust#137944 got merged with Part I of the Sized Hierarchy work
  6551. &lt;ul&gt;
  6552. &lt;li&gt;A bug was discovered through fuzzing when the feature was enabled, users could write &lt;code&gt;dyn PointeeSized&lt;/code&gt; which would trigger the builtin impl for &lt;code&gt;PointeeSized&lt;/code&gt;, which doesn't exist. rust-lang/rust#143104 was merged to fix that.&lt;/li&gt;
  6553. &lt;li&gt;In attempt to experiment with relaxing &lt;code&gt;Deref::Target&lt;/code&gt;, we discovered that sizedness supertraits weren't being elaborated from where bounds on projections.
  6554. &lt;ul&gt;
  6555. &lt;li&gt;Adding those bounds meant that there could be two candidates for some obligations - from a where bound and from an item bound - where previously there would only be the item bound. Where bounds take priority and this could result in regions being equated that did not previously.&lt;/li&gt;
  6556. &lt;li&gt;By fixing that, we ran into issues with normalisation that was happening which restricted what code using GATs was accepted. Fixing this got everything passing but more code is accepted.&lt;/li&gt;
  6557. &lt;li&gt;rust-lang/rust#142712 has this fixed, but isn't yet merged as it's quite involved.&lt;/li&gt;
  6558. &lt;/ul&gt;
  6559. &lt;/li&gt;
  6560. &lt;/ul&gt;
  6561. &lt;/li&gt;
  6562. &lt;li&gt;I've still not made any changes to the Sized Hierarchy RFC, there's a small amount of discussion which will be responded to once the implementation has landed.&lt;/li&gt;
  6563. &lt;li&gt;While implementing Part II of the Sized Hierarchy work, we ran into limitations of the old solver w/r/t host effect predicates around coinductive cycles. We've put that aside until there's nothing else to do or the new solver is ready.&lt;/li&gt;
  6564. &lt;li&gt;We've been reviving the RFC and implementation of the SVE infrastructure, relying on some exceptions because of not having const sizedness yet, but knowing that we've got a solution for that coming, we're hoping to see this merged as an experiment once it is ready.&lt;/li&gt;
  6565. &lt;li&gt;We've opened rust-lang/rust#144404 that documents the current status of the Sized Hierarchy feature and our plans for it.
  6566. &lt;ul&gt;
  6567. &lt;li&gt;As before, implementing const sizedness is on hold until the next solver is ready or there's nothing else to do.&lt;/li&gt;
  6568. &lt;li&gt;We've opened rust-lang/rust#144064 with the interesting parts of rust-lang/rust#142712 from a t-types perspective, that's currently waiting on FCP checkboxes.
  6569. &lt;ul&gt;
  6570. &lt;li&gt;This will enable experimentation with relaxing &lt;code&gt;Deref::Target&lt;/code&gt; to &lt;code&gt;PointeeSized&lt;/code&gt;.&lt;/li&gt;
  6571. &lt;/ul&gt;
  6572. &lt;/li&gt;
  6573. &lt;/ul&gt;
  6574. &lt;/li&gt;
  6575. &lt;li&gt;We've opened rust-lang/rfcs#3838 and rust-lang/rust#143924 updating rust-lang/rfcs#3268 and rust-lang/rust#118917 respectively.
  6576. &lt;ul&gt;
  6577. &lt;li&gt;There's been lots of useful feedback on this that we're working on addressing and will have an update soon&lt;/li&gt;

  6603. &lt;li&gt;While implementing Part II of the Sized Hierarchy work, we ran into limitations of the old solver w/r/t host effect predicates around coinductive cycles. We've put that aside until there's nothing else to do or the new solver is ready.&lt;/li&gt;
  6604. &lt;li&gt;We've been reviving the RFC and implementation of the SVE infrastructure, relying on some exceptions because of not having const sizedness yet, but knowing that we've got a solution for that coming, we're hoping to see this merged as an experiment once it is ready.&lt;/li&gt;
  6605. &lt;/ul&gt;
  6606.  
  6607. &lt;/blockquote&gt;
  6608.

  6610. &lt;blockquote&gt;
  6611.  
  6612. &lt;ul&gt;
  6613. &lt;li&gt;We've opened rust-lang/rust#144404 that documents the current status of the Sized Hierarchy feature and our plans for it.
  6614. &lt;ul&gt;
  6615. &lt;li&gt;As before, implementing const sizedness is on hold until the next solver is ready or there's nothing else to do.&lt;/li&gt;
  6616. &lt;li&gt;We've opened rust-lang/rust#144064 with the interesting parts of rust-lang/rust#142712 from a t-types perspective, that's currently waiting on FCP checkboxes.
  6617. &lt;ul&gt;
  6618. &lt;li&gt;This will enable experimentation with relaxing &lt;code&gt;Deref::Target&lt;/code&gt; to &lt;code&gt;PointeeSized&lt;/code&gt;.&lt;/li&gt;
  6619. &lt;/ul&gt;
  6620. &lt;/li&gt;
  6621. &lt;/ul&gt;
  6622. &lt;/li&gt;
  6623. &lt;li&gt;We've opened rust-lang/rfcs#3838 and rust-lang/rust#143924 updating rust-lang/rfcs#3268 and rust-lang/rust#118917 respectively.
  6624. &lt;ul&gt;
  6625. &lt;li&gt;There's been lots of useful feedback on this that we're working on addressing and will have an update soon&lt;/li&gt;
  6626. &lt;/ul&gt;
  6627. &lt;/li&gt;

  6653.  
  6654. &lt;p&gt;Key developments&lt;/p&gt;
  6655. &lt;ul&gt;
  6656. &lt;li&gt;The new API for &lt;code&gt;annotate-snippets&lt;/code&gt; got merged (and tweaked)&lt;/li&gt;
  6657. &lt;li&gt;&lt;a href=&quot;https://asciinema.org/a/MlUN66AxlyLbaJ9VP8zDWlutt&quot;&gt;&lt;code&gt;annotate-snippets&lt;/code&gt; passed all of &lt;code&gt;rustc&lt;/code&gt;'s UI tests for the first time&lt;/a&gt;&lt;/li&gt;
  6658. &lt;li&gt;I started getting &lt;code&gt;annotate-snippets&lt;/code&gt; ready for release&lt;/li&gt;
  6659. &lt;li&gt;&lt;a href=&quot;https://github.com/rust-lang/rust/pulls?q=is%3Apr+author%3AMuscraft+created%3A%3E2025-03-31+&quot;&gt;I started opening PRs&lt;/a&gt; to get &lt;code&gt;rustc&lt;/code&gt; to match &lt;code&gt;annotate-snippets&lt;/code&gt; planned output changes&lt;/li&gt;
  6660. &lt;/ul&gt;
  6661. &lt;p&gt;Blockers&lt;/p&gt;
  6662. &lt;p&gt;Help wanted&lt;/p&gt;

  6736. &lt;li&gt;A new onUserSettingsChanged API event has been added to the action API namespace to allow the extensions to be notified when their toolbar button is pinned/unpinned from the toolbar – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1828220&quot;&gt;Bug 1828220&lt;/a&gt;&lt;/li&gt;

  6742. &lt;/ul&gt;
  6743. &lt;h3&gt;DevTools&lt;/h3&gt;
  6744. &lt;ul&gt;
  6745. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=774415&quot;&gt;William&lt;/a&gt; improved the rendering of @font-face declaration in the Inspector Fonts panel (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1960743&quot;&gt;#1960743&lt;/a&gt;)&lt;/li&gt;
  6746. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=688976&quot;&gt;Manuel Bucher [:manuel]&lt;/a&gt; added MDN link in Netmonitor for Alt-Svc and Alt-Used headers (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1977374&quot;&gt;#1977374&lt;/a&gt;)&lt;/li&gt;
  6747. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=13647&quot;&gt;:glob ✱&lt;/a&gt; fixed browser_devices.js test (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1975963&quot;&gt;#1975963&lt;/a&gt;)&lt;/li&gt;
  6748. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=763731&quot;&gt;Holger Benl [:hbenl]&lt;/a&gt; fixed an issue in Responsive Design Mode touch simulation where we would trigger too many events on pages with same-origin iframes (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973691&quot;&gt;#1973691&lt;/a&gt;)&lt;/li&gt;
  6749. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=283262&quot;&gt;Alexandre Poirot [:ochameau]&lt;/a&gt; fixed an issue in the Netmonitor where Search results would collapsed when new requests were added to the main list (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1975441&quot;&gt;#1975441&lt;/a&gt;)&lt;/li&gt;
  6750. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=656417&quot;&gt;Hubert Boma Manilla (:bomsy)&lt;/a&gt; improved Netmonitor so Request Headers/Cookies/Params are displayed even if the request isn’t finished yet (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1557795&quot;&gt;#1557795&lt;/a&gt;)&lt;/li&gt;

  6752. &lt;ul&gt;
  6753. &lt;li&gt;See &lt;a href=&quot;https://firefox-source-docs.mozilla.org/devtools/tests/node-tests.html#:~:text=devtools-node-test&quot;&gt;docs&lt;/a&gt;&lt;/li&gt;
  6754. &lt;li&gt;e.g. mach devtools-node-test –suite webconsole&lt;/li&gt;
  6755. &lt;/ul&gt;
  6756. &lt;/li&gt;
  6757. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=557153&quot;&gt;Nicolas Chevobbe [:nchevobbe]&lt;/a&gt; made the “Grid” section in the layout panel to also show shadow DOM grid containers (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1834249&quot;&gt;#1834249&lt;/a&gt;)&lt;/li&gt;
  6758. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=557153&quot;&gt;Nicolas Chevobbe [:nchevobbe]&lt;/a&gt; improved performance of Inspector compatibility panel (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976868&quot;&gt;#1976868&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976876&quot;&gt;#1976876&lt;/a&gt;), and the Rules view for pages with lots of CSS variables declarations (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1977550&quot;&gt;#1977550&lt;/a&gt;)&lt;/li&gt;
  6759. &lt;/ul&gt;
  6760. &lt;h3&gt;WebDriver BiDi&lt;/h3&gt;
  6761. &lt;ul&gt;
  6762. &lt;li&gt;Thanks to :biyul for &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1931528&quot;&gt;reverting a workaround&lt;/a&gt; used to avoid incorrect properties in our network events, but no longer needed thanks to improvements on Necko side.&lt;/li&gt;
  6763. &lt;li&gt;Henrik refactored all the &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1344267&quot;&gt;Marionette test files for chrome scope to no longer ship with Firefox&lt;/a&gt;. This also removed the last shipped DTD file, which allowed further cleanup. The chrome test file for reftests was updated to include necessary CSP directives.&lt;/li&gt;
  6764. &lt;li&gt;Thanks to this, Henrik could finally &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1963356&quot;&gt;remove the Marionette exceptions for CSPs&lt;/a&gt;.&lt;/li&gt;
  6765. &lt;li&gt;:biyul also &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976504&quot;&gt;removed support for “localize_entity” from localization &lt;/a&gt;module, which was only useful when used against DTD files, and therefore no longer needed.&lt;/li&gt;
  6766. &lt;li&gt;Henrik &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972670&quot;&gt;cleaned up remaining code for support of FTP proxy in WebDriver capabilities&lt;/a&gt;. This feature has not been supported since Firefox 90.&lt;/li&gt;
  6767. &lt;li&gt;Sasha added &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1968951&quot;&gt;an API to BrowsingContext to override locale in JS APIs&lt;/a&gt; and &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1954992&quot;&gt;a new &lt;/a&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1968952&quot;&gt;“emulation.setLocaleOverride” WebDriver BiDi command&lt;/a&gt;, which utilizes the new BrowsingContext property under the hood.&lt;/li&gt;
  6768. &lt;li&gt;Sasha updated &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1977205&quot;&gt;the Marionette command for adding cookies to throw an error&lt;/a&gt; when a cookie has with “sameSite=none” and “secure=false” values.&lt;/li&gt;
  6769. &lt;li&gt;Also, Sasha improved setting a proxy with “browsingContext.createUserContext”: added &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1977180&quot;&gt;support host patterns like “.mozilla.org” in “noProxy” property&lt;/a&gt; and fixed &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1977168&quot;&gt;a bug when setting an http proxy wouldn’t let to navigate to HTTPS URLs&lt;/a&gt;.&lt;/li&gt;
  6770. &lt;/ul&gt;
  6771. &lt;h3&gt;Lint, Docs and Workflow&lt;/h3&gt;
  6772. &lt;ul&gt;
  6773. &lt;li&gt;Standard8 added a &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1940283&quot;&gt;linter to check that licenses are acceptable for the node modules&lt;/a&gt; included via the top-level and eslint-plugin-mozilla package.json files.
  6774. &lt;ul&gt;
  6775. &lt;li&gt;This will be expanded to more package.json files in future.&lt;/li&gt;
  6776. &lt;li&gt;&lt;a href=&quot;https://firefox-source-docs.mozilla.org/code-quality/lint/linters/node-licenses.html&quot;&gt;Linter Docs&lt;/a&gt;&lt;/li&gt;
  6777. &lt;li&gt;&lt;a href=&quot;https://mozilla-hub.atlassian.net/wiki/spaces/SLP/pages/27394064/Licensing+Runbook+Software+Licensing+And+Code+Contribution+Between+Mozilla+And+Other+Orgs+Projects&quot;&gt;Runbook&lt;/a&gt;&lt;/li&gt;
  6778. &lt;/ul&gt;
  6779. &lt;/li&gt;
  6780. &lt;/ul&gt;
  6781. &lt;h3&gt;Profile Management&lt;/h3&gt;
  6782. &lt;ul&gt;
  6783. &lt;li&gt;We bumped from 0.5% to 1.5% of release, metrics looking good&lt;/li&gt;
  6784. &lt;/ul&gt;
  6785. &lt;h3&gt;Search and Navigation&lt;/h3&gt;
  6786. &lt;ul&gt;
  6787. &lt;li&gt;New implementation of Trust Panel that combines and replaces Privacy and Shield urlbar icons has landed (disabled) – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1967512&quot;&gt;1967512&lt;/a&gt;
  6788. &lt;ul&gt;
  6789. &lt;li&gt;browser.urlbar.trustPanel.featureGate&lt;/li&gt;
  6790. &lt;/ul&gt;
  6791. &lt;/li&gt;
  6792. &lt;/ul&gt;
  6793. &lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;alignnone size-large wp-image-1872&quot; height=&quot;544&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/08/headlines184_2-600x544.png&quot; width=&quot;600&quot; /&gt;&lt;/p&gt;
  6794. &lt;ul&gt;
  6795. &lt;li&gt;Mandy has been working on Perplexity implementation @ &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971178&quot;&gt;1971178&lt;/a&gt;&lt;/li&gt;
  6796. &lt;li&gt;Moritz fixed issue with context menu in “Add Search Engine” fields&lt;/li&gt;
  6797. &lt;li&gt;Dao fixed tab search mode layout issue @ &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976031&quot;&gt;1976031&lt;/a&gt; and Switch to tab truncation issue @ &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976277&quot;&gt;1976277&lt;/a&gt;&lt;/li&gt;
  6798. &lt;li&gt;Daisuke has landed a new split button component in preparation for new urlbar result types @ &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1975336&quot;&gt;1975336&lt;/a&gt;&lt;/li&gt;
  6799. &lt;li&gt;Drew has landed patches preparing for visual search capability @ &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1976993&quot;&gt;1976993&lt;/a&gt;&lt;/li&gt;
  6800. &lt;/ul&gt;
  6801. &lt;h3&gt;Tab Groups&lt;/h3&gt;
  6802. &lt;ul&gt;
  6803. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971232&quot;&gt;1971232 – [meta] Allow the active tab to be in a collapsed tab group&lt;/a&gt; available in Nightly 143, still in progress&lt;/li&gt;

  6809. <title>Mozilla Addons Blog: Warning: Phishing campaign detected</title>
  6810. <guid isPermaLink="false">https://blog.mozilla.org/addons/?p=9248</guid>
  6811. <link>https://blog.mozilla.org/addons/2025/08/01/warning-phishing-campaign-detected/</link>
  6812. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;alignleft size-medium wp-image-8771&quot; height=&quot;249&quot; src=&quot;https://blog.mozilla.org/addons/files/2019/12/Firefox-parent-brand-logo-252x249.png&quot; width=&quot;252&quot; /&gt;The developer community should be aware we’ve detected a phishing campaign targeting AMO (&lt;a href=&quot;http://addons.mozilla.org&quot;&gt;addons.mozilla.org&lt;/a&gt;) accounts. Add-on developers should exercise extreme caution and scrutiny when receiving emails claiming to be from Mozilla/AMO. Phishing emails typically state some variation of the message “Your Mozilla Add-ons account requires an update to continue accessing developer features.”&lt;/p&gt;
  6813. &lt;p&gt;In order to protect yourself and keep your AMO account secure, we strongly recommend that you:&lt;/p&gt;
  6814. &lt;ol&gt;
  6815. &lt;li&gt;&lt;strong&gt;Do not click any links in the email&lt;/strong&gt;.&lt;/li&gt;
  6816. &lt;li&gt;Verify the email was sent by a Mozilla-owned domain: &lt;b&gt;firefox.com&lt;/b&gt;, &lt;b&gt;mozilla.com, &lt;/b&gt;&lt;b&gt;mozilla.org, &lt;/b&gt;&lt;b&gt;mozillafoundation.org &lt;/b&gt;(or their subdomains).&lt;/li&gt;
  6817. &lt;li&gt;Ensure that the email passes SPF, DKIM, and DMARC checks (consult your email provider and/or email client’s support documentation for details).&lt;/li&gt;
  6818. &lt;li&gt;Validate that links in the email point to &lt;b&gt;firefox.com&lt;/b&gt;, &lt;b&gt;mozilla.com, &lt;/b&gt;&lt;b&gt;mozilla.org, &lt;/b&gt;&lt;b&gt;mozillafoundation.org &lt;/b&gt;(or their subdomains) before opening them; even better, navigate directly to these domains rather than clicking a link via email.&lt;/li&gt;
  6819. &lt;li&gt;Only enter your Mozilla username and password on Mozilla-owned domains.&lt;/li&gt;
  6820. &lt;/ol&gt;
  6821. &lt;p&gt;For more information on how to detect and report phishing scams, please see these helpful guides from the &lt;a href=&quot;https://consumer.ftc.gov/articles/how-recognize-and-avoid-phishing-scams&quot; rel=&quot;noopener&quot; target=&quot;_blank&quot;&gt;U.S. Federal Trade Commission&lt;/a&gt; and the &lt;a href=&quot;https://www.ncsc.gov.uk/collection/phishing-scams/spot-scams&quot; rel=&quot;noopener&quot; target=&quot;_blank&quot;&gt;U.K. National Cyber Security Centre&lt;/a&gt;, or consult your local government.&lt;/p&gt;
  6822. &lt;p&gt;If we uncover more details to share we’ll update this post accordingly.&lt;/p&gt;

  6828. <title>Mozilla Thunderbird: Monthly Release 141 Recap</title>
  6829. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3645</guid>
  6830. <link>https://blog.thunderbird.net/2025/08/monthly-release-141-recap/</link>
  6831. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/blog-desktop-month-release-series-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  6832. &lt;p&gt;We’re launching a brand new series that will highlight features and improvements with Thunderbird 141.0 – your front row ticket to Thunderbird’s monthly enhancements! (No more waiting in the wings so to speak). Learn what’s new, why it matters, and how it’ll transform your inbox experience.&lt;/p&gt;
  6833.  
  6834.  
  6835.  
  6836. &lt;p&gt;In March, &lt;a href=&quot;https://blog.thunderbird.net/2025/03/thunderbird-release-channel-update/&quot;&gt;we introduced&lt;/a&gt; a new monthly Release channel and swapped it as the default option on the&lt;a href=&quot;https://thunderbird.net/&quot;&gt; Thunderbird.net&lt;/a&gt; downloads page.&lt;/p&gt;
  6837.  
  6838.  
  6839.  
  6840. &lt;p&gt;As a quick refresher, Thunderbird now offers two core release channel options:&lt;/p&gt;
  6841.  
  6842.  
  6843.  
  6844. &lt;ol&gt;
  6845. &lt;li&gt;&lt;strong&gt;Release Channel:&lt;/strong&gt; Updated monthly with new features, performance boosts, and bug fixes as they land.&lt;/li&gt;
  6846.  
  6847.  
  6848.  
  6849. &lt;li&gt;&lt;strong&gt;ESR (Extended Support Release): &lt;/strong&gt;Receives all of the above in one major annual update, focusing on stability, with point security and stability patches in between.&lt;/li&gt;
  6850. &lt;/ol&gt;
  6851.  
  6852.  
  6853.  
  6854. &lt;p&gt;While both versions are equally stable, the Release channel provides faster access to cutting-edge tools and optimizations, while the ESR channel may provide more stability when using add-ons with Thunderbird.&lt;/p&gt;
  6855.  
  6856.  
  6857.  
  6858. &lt;p&gt;Feedback on the Release channel has been overwhelmingly positive, with many users transitioning from ESR. To join them:&lt;/p&gt;
  6859.  
  6860.  
  6861.  
  6862. &lt;ul&gt;
  6863. &lt;li&gt;Visit the Release download portal:&lt;a href=&quot;https://updates.thunderbird.net/thunderbird/128.0/monthly/&quot;&gt; Thunderbird Release Page&lt;/a&gt;.&lt;/li&gt;
  6864.  
  6865.  
  6866.  
  6867. &lt;li&gt;&lt;a href=&quot;https://support.mozilla.org/en-US/kb/thunderbird-release&quot;&gt;Explore detailed comparisons&lt;/a&gt; and migration guides.&lt;/li&gt;
  6868. &lt;/ul&gt;
  6869.  
  6870.  
  6871.  
  6872. &lt;p&gt;Now that we’ve gotten the formalities out of the way, let’s jump in to what’s new in 141.0!&lt;/p&gt;
  6873.  
  6874.  
  6875.  
  6876. &lt;h3&gt;&lt;strong&gt;New Features&lt;/strong&gt;&lt;/h3&gt;
  6877.  
  6878.  
  6879.  
  6880. &lt;h4&gt;&lt;strong&gt;Warning for Expiring PGP Keys&lt;/strong&gt;&lt;/h4&gt;
  6881.  
  6882.  
  6883.  
  6884. &lt;p&gt;Thunderbird loves PGP like cats adore cardboard boxes! We prioritize user trust by making end-to-end encrypted email simple for everyone, from newcomers to experienced users. To help you get started or refresh your knowledge, our team and volunteers have written&lt;a href=&quot;https://support.mozilla.org/kb/introduction-to-e2e-encryption&quot;&gt; an excellent introduction&lt;/a&gt; to the topic, as well as a&lt;a href=&quot;https://support.mozilla.org/kb/openpgp-thunderbird-howto-and-faq&quot;&gt; How-to and FAQ.&lt;/a&gt;&lt;/p&gt;
  6885.  
  6886.  
  6887.  
  6888. &lt;p&gt;Key expiration serves as a security safeguard, requiring proactive renewal procedures that reinforce operational encryption competencies.&lt;/p&gt;
  6889.  
  6890.  
  6891.  
  6892. &lt;p&gt;What changed:&lt;/p&gt;
  6893.  
  6894.  
  6895.  
  6896. &lt;ul&gt;
  6897. &lt;li&gt;Your warning light is lit: If your public key expires in 31 days, Thunderbird now flashes a red alert in the compose window. No post-expiry panic!&lt;/li&gt;
  6898. &lt;/ul&gt;
  6899.  
  6900.  
  6901.  
  6902. &lt;p&gt;Why it matters:&lt;/p&gt;
  6903.  
  6904.  
  6905.  
  6906. &lt;ul&gt;
  6907. &lt;li&gt;Safety net: A key that auto-expires nudges you to refresh it.&lt;/li&gt;
  6908.  
  6909.  
  6910.  
  6911. &lt;li&gt;Piece of mind: Before Thunderbird told you after-the-fact your key died. Now? Your inbox is proactive.&lt;/li&gt;
  6912. &lt;/ul&gt;
  6913.  
  6914.  
  6915.  
  6916. &lt;h4&gt;&lt;strong&gt;Archive from OS Notifications&lt;/strong&gt;&lt;/h4&gt;
  6917.  
  6918.  
  6919.  
  6920. &lt;p&gt;The&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1953661&quot;&gt; improvements to native notifications&lt;/a&gt; keep coming. Now, in addition to deleting a message, marking it as spam, or starring it, you can archive a message directly from your operating system’s notifications.  &lt;/p&gt;
  6921.  
  6922.  
  6923.  
  6924. &lt;p&gt;By default, the notifications you see include “Mark as Read” and “Delete”, however they can be customized further by going to &lt;em&gt;Thunderbird Settings → General→ Incoming Mails&lt;/em&gt; and clicking on &lt;em&gt;Customize&lt;/em&gt;.&lt;/p&gt;
  6925.  
  6926.  
  6927.  
  6928. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/07/settings-1.jpg&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3659&quot; height=&quot;500&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/settings-1.jpg&quot; width=&quot;1910&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  6929.  
  6930.  
  6931.  
  6932. &lt;p&gt;Here you can select the information you want to see in your notification, as well as the actions you’d like to perform with it.&lt;/p&gt;
  6933.  
  6934.  
  6935.  
  6936. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/07/customize-options-2-2.jpg&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3683&quot; height=&quot;598&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/customize-options-2-2.jpg&quot; width=&quot;404&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  6937.  
  6938.  
  6939.  
  6940. &lt;p&gt;What changed:&lt;/p&gt;
  6941.  
  6942.  
  6943.  
  6944. &lt;ul&gt;
  6945. &lt;li&gt;New mail notifications have added the ‘Archive’ action.&lt;/li&gt;
  6946. &lt;/ul&gt;
  6947.  
  6948.  
  6949.  
  6950. &lt;p&gt;Why it matters:&lt;/p&gt;
  6951.  
  6952.  
  6953.  
  6954. &lt;ul&gt;
  6955. &lt;li&gt;No need to go into the Thunderbird app to archive an incoming email now. More actions in notifications give you time to do the things you want, instead of managing your inbox.&lt;/li&gt;
  6956. &lt;/ul&gt;
  6957.  
  6958.  
  6959.  
  6960. &lt;h3&gt;&lt;strong&gt;Bug Fixes&lt;/strong&gt;&lt;/h3&gt;
  6961.  
  6962.  
  6963.  
  6964. &lt;h4&gt;&lt;strong&gt;Prioritize Link Hover URL in Status Bar&lt;/strong&gt;&lt;/h4&gt;
  6965.  
  6966.  
  6967.  
  6968. &lt;p&gt;Thunderbird includes numerous features to protect you from suspicious mail and bad actors. One of these tools involves checking the URL of a link by hovering your mouse over the link text. The status bar would display the link URL, but it could be&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1947026&quot;&gt; overwritten in fractions of a second&lt;/a&gt; by “Downloading message” and “Opening folder” messages. We’ve fixed this, and now the URL you’re hovering over will get priority in the status bar.&lt;/p&gt;
  6969.  
  6970.  
  6971.  
  6972. &lt;p&gt;What changed:&lt;/p&gt;
  6973.  
  6974.  
  6975.  
  6976. &lt;ul&gt;
  6977. &lt;li&gt;Hovering over a link in an email will display it in the status bar without being immediately overwritten by other messages.&lt;/li&gt;
  6978. &lt;/ul&gt;
  6979.  
  6980.  
  6981.  
  6982. &lt;p&gt;Why it matters:&lt;/p&gt;
  6983.  
  6984.  
  6985.  
  6986. &lt;ul&gt;
  6987. &lt;li&gt;Knowing where an email wants to send you is a major security boost, especially with the widespread threat of phishing emails.&lt;/li&gt;
  6988. &lt;/ul&gt;
  6989.  
  6990.  
  6991.  
  6992. &lt;h4&gt;&lt;strong&gt;Dots, Dashes, and Advanced Address Book Search&lt;/strong&gt;&lt;/h4&gt;
  6993.  
  6994.  
  6995.  
  6996. &lt;p&gt;Three months ago, a community member noted that while the CardBook add-on could find phone numbers that used dots for separators, the&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1962868&quot;&gt; Advanced Address Book Search in Thunderbird could not&lt;/a&gt;. Since we want users to be able to find contacts, and use the phone number formatting they want as well, we’ve built this ability into Thunderbird.&lt;/p&gt;
  6997.  
  6998.  
  6999.  
  7000. &lt;p&gt;What changed:&lt;/p&gt;
  7001.  
  7002.  
  7003.  
  7004. &lt;ul&gt;
  7005. &lt;li&gt;The advanced address book in Thunderbird now recognizes phone numbers that use dots for separators.&lt;/li&gt;
  7006. &lt;/ul&gt;
  7007.  
  7008.  
  7009.  
  7010. &lt;p&gt;Why it matters:&lt;/p&gt;
  7011.  
  7012.  
  7013.  
  7014. &lt;ul&gt;
  7015. &lt;li&gt;Saves time: Finds contacts faster and more accurately, no matter their format or storage location, eliminating need for manual cleanup or repeat searches.&lt;/li&gt;
  7016. &lt;/ul&gt;
  7017.  
  7018.  
  7019.  
  7020. &lt;h3&gt;&lt;strong&gt;Performance Improvements&lt;/strong&gt;&lt;/h3&gt;
  7021.  
  7022.  
  7023.  
  7024. &lt;h4&gt;&lt;strong&gt;Message List Scroll&lt;/strong&gt;&lt;/h4&gt;
  7025.  
  7026.  
  7027.  
  7028. &lt;p&gt;To address message list scrolling performance, we adjusted how new rows are rendered but inadvertently introduced display delays. We’re reverting to the&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971655&quot;&gt; original row-handling method&lt;/a&gt; to properly assess performance impact before considering this change for Extended Support Release adoption. This allows precise measurement of optimizations against potential trade-offs, ensuring reliable performance in production environments.&lt;/p&gt;
  7029.  
  7030.  
  7031.  
  7032. &lt;p&gt;What changed:&lt;/p&gt;
  7033.  
  7034.  
  7035.  
  7036. &lt;ul&gt;
  7037. &lt;li&gt;Reverting back to the previous method for how rows are updated.&lt;/li&gt;

  7057. <description>&lt;p&gt;&lt;i&gt;Please note some of the information provided in this report may be subject to change as we are sometimes sharing information about projects that are still in early stages and are not final yet. &lt;/i&gt;&lt;/p&gt;
  7058. &lt;h3&gt;Welcome!&lt;/h3&gt;
  7059. &lt;p&gt;New localizers&lt;/p&gt;
  7060. &lt;ul&gt;
  7061. &lt;li&gt;&lt;a href=&quot;https://pontoon.mozilla.org/contributors/tragivictoria/&quot;&gt;Victoria&lt;/a&gt; for the Polish community&lt;/li&gt;
  7062. &lt;/ul&gt;

  7064. &lt;h3&gt;What’s new or coming up in Firefox desktop&lt;/h3&gt;
  7065. &lt;h4&gt;Where’s Firefox Going Next?&lt;/h4&gt;
  7066. &lt;p&gt;Before getting into all the new features that recently landed in Nightly, we’re trying something new and would love your help. Check out &lt;a href=&quot;https://connect.mozilla.org/t5/discussions/where-s-firefox-going-next-you-tell-us/m-p/100698&quot;&gt;this thread&lt;/a&gt; over on Mozilla Connect where you can help Firefox’s product managers plan their upcoming AMA (Ask Me Anything) by letting them know what you’ve always wanted to ask the Firefox team and which topics should be covered during the AMA.&lt;/p&gt;
  7067. &lt;h4&gt;Trust Panel&lt;/h4&gt;
  7068. &lt;p&gt;Available to translate and test in Nightly, the trust panel is a new feature designed to communicate to users what Firefox is doing to protect their privacy in friendly and easy to understand language. To check the feature out and review your translations, make sure to update your Nightly to the latest version (143) then navigate to “about:config” by typing it into your URL bar, click past the warning, then search &lt;code&gt;browser.urlbar.trustPanel.featureGate&lt;/code&gt; and toggle the value to &lt;code&gt;true&lt;/code&gt;.&lt;/p&gt;
  7069. &lt;p&gt;Navigate to a website and the icon will appear on the side of your URL bar.&lt;/p&gt;
  7070. &lt;p&gt;&lt;a href=&quot;https://blog.mozilla.org/l10n/files/2025/07/trust_icon.png&quot;&gt;&lt;img alt=&quot;Firefox address bar showing a shield icon to access the trust panel.&quot; class=&quot;aligncenter size-large wp-image-1779&quot; height=&quot;294&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/07/trust_icon-600x294.png&quot; width=&quot;600&quot; /&gt;&lt;/a&gt;Clicking on it will show you the trust panel with a friendly Firefox letting you know you’re protected!&lt;/p&gt;
  7071. &lt;h4&gt;&lt;a href=&quot;https://blog.mozilla.org/l10n/files/2025/07/trust_panel.png&quot;&gt;&lt;img alt=&quot;Screenshot of the new unified trust panel in Firefox, displayed when clicking the shield icon.&quot; class=&quot;aligncenter size-full wp-image-1780&quot; height=&quot;364&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/07/trust_panel.png&quot; width=&quot;493&quot; /&gt;&lt;/a&gt;Profile Icons&lt;/h4&gt;
  7072. &lt;p&gt;Also recently landed was a large number of strings related to icons users can set as part of the recently added profiles feature. While we tried to make the comments as helpful as possible, there’s no substitute for seeing the image in context. You can check the icons out within Nightly yourself by editing or creating a new profile by clicking the Account button on your toolbar and selecting the Profiles menu. Or, you can refer to the following image with a screenshot and the associated name used in the string IDs.&lt;/p&gt;
  7073. &lt;h4&gt;&lt;a href=&quot;https://www.google.com/url?q=https://docs.google.com/spreadsheets/d/e/2PACX-1vQoa6EIeD4WeEWI6LAnfPl5aCL6XIvUXUe8zL4Oc__45EEoxcxPCEMjmxf3d8DvJeGlMAFjs6as3vq6/pubhtml&amp;amp;sa=D&amp;amp;source=docs&amp;amp;ust=1753979421699619&amp;amp;usg=AOvVaw2FNSKgzrW8jIljcCchhKIb&quot;&gt;&lt;img alt=&quot;Screenshot of new profile icons and their accessible names.&quot; class=&quot;aligncenter wp-image-1781 size-large&quot; height=&quot;342&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/07/profile_icons-600x342.png&quot; width=&quot;600&quot; /&gt;&lt;/a&gt;Text Fragments&lt;/h4&gt;
  7074. &lt;p&gt;You can now test the text fragments creation UI (&lt;a href=&quot;https://github.com/mozilla-l10n/firefox-l10n-source/blob/7825b65e8147f4890bcc8eb281bb306e1c655216/toolkit/toolkit/global/textActions.ftl#L76-L92&quot;&gt;these strings&lt;/a&gt; were added a few months back, but they have just been activated in Firefox Nightly). This feature allows you to share/reference a link anchor to any text snippet in a page. See the team’s post about this feature &lt;a href=&quot;https://mastodon.social/@firefoxnightly/114805708639661562&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;
  7075. &lt;h3&gt;What’s new or coming up in mobile&lt;/h3&gt;
  7076. &lt;p&gt;The menu settings on Firefox for Android and iOS are being redesigned, which requires updates to some strings. Stay tuned as more are coming in!&lt;/p&gt;
  7077. &lt;h3&gt;What’s new or coming up in web projects&lt;/h3&gt;
  7078. &lt;h4&gt;Firefox.com&lt;/h4&gt;
  7079. &lt;p&gt;The new &lt;a href=&quot;https://www.firefox.com&quot;&gt;Firefox.com&lt;/a&gt; site officially launched earlier this month following a soft launch period, which allowed time to identify and resolve any initial issues. Thank you to everyone who reported bugs during that time. Most of the content on the new site was copied from Mozilla.org. However, the team plans to remove duplicated pages over the next few months except for a few that will remain on both sites, such as the &lt;em&gt;Thank You&lt;/em&gt; page. More substantial updates are planned for later this year and beyond.&lt;/p&gt;
  7080. &lt;h3&gt;What’s new or coming up in Pontoon&lt;/h3&gt;
  7081. &lt;h4&gt;Unified plurals UI&lt;/h4&gt;
  7082. &lt;p&gt;We’ve updated how plural gettext (.po) messages are handled in Pontoon. Specifically, they now use the same UI we’ve already been using for Fluent strings.&lt;/p&gt;
  7083. &lt;p&gt;We’d really appreciate your feedback! To explore the new plural editor, try searching for strings that include &lt;a href=&quot;https://pontoon.mozilla.org/projects/all-projects/all-resources/?search=.match&quot;&gt;.match&lt;/a&gt;, which commonly contain plural forms. We’re especially interested in whether the new experience feels &lt;b&gt;intuitive&lt;/b&gt; and &lt;b&gt;“right”&lt;/b&gt;, and — most importantly — if you manage to break it.&lt;/p&gt;
  7084. &lt;h4&gt;&lt;a href=&quot;https://blog.mozilla.org/l10n/files/2025/07/gettext_plural_ui.jpg&quot;&gt;&lt;img alt=&quot;Screenshot of UI in Pontoon showing a string with plurals in a gettext based project&quot; class=&quot;aligncenter size-large wp-image-1782&quot; height=&quot;527&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/07/gettext_plural_ui-600x527.jpg&quot; width=&quot;600&quot; /&gt;&lt;/a&gt;New REST API Now Available&lt;/h4&gt;
  7085. &lt;p&gt;We’re excited to announce that Pontoon now offers a &lt;b&gt;new REST API&lt;/b&gt;, built with Django REST Framework! This API is designed to provide a more reliable and consistent way to interact with Pontoon programmatically, and it’s already available for use.&lt;/p&gt;
  7086. &lt;p&gt;You can explore the available endpoints and usage examples in the &lt;a href=&quot;https://github.com/mozilla/pontoon/tree/main/pontoon/api#rest-api&quot;&gt;API README&lt;/a&gt;.&lt;/p&gt;
  7087. &lt;h4&gt;GraphQL API Scheduled for Deprecation&lt;/h4&gt;
  7088. &lt;p&gt;As part of this transition, we’ll be &lt;a href=&quot;https://github.com/mozilla/pontoon/discussions/3745&quot;&gt;&lt;b&gt;deprecating&lt;/b&gt;&lt;/a&gt;&lt;b&gt; the Pontoon GraphQL API on November 5th, 2025&lt;/b&gt;. If you’re currently using the GraphQL API, we strongly encourage you to begin migrating to the new REST API, which will become the only supported interface going forward.&lt;/p&gt;
  7089. &lt;p&gt;If you have any questions during the transition or run into issues, please don’t hesitate to&lt;a href=&quot;https://github.com/mozilla/pontoon/discussions&quot;&gt; open a discussion&lt;/a&gt; or&lt;a href=&quot;https://github.com/mozilla/pontoon/issues&quot;&gt; file an issue&lt;/a&gt;. We’re here to help!&lt;/p&gt;

  7124. <title>Niko Matsakis: Rust, Python, and TypeScript: the new trifecta</title>
  7125. <guid isPermaLink="false">https://smallcultfollowing.com/babysteps/blog/2025/07/31/rs-py-ts-trifecta/</guid>
  7126. <link>https://smallcultfollowing.com/babysteps/blog/2025/07/31/rs-py-ts-trifecta/?utm_source=atom_feed</link>
  7127. <description>&lt;p&gt;You heard it here first: my guess is that Rust, Python, and TypeScript are going to become the dominant languages going forward (excluding the mobile market, which has extra wrinkles). The argument is simple. Increasing use of AI coding is going to weaken people’s loyalty to programming languages, moving it from what is often a tribal decision to one based on fundamentals. And the fundamentals for those 3 languages look pretty strong to me: Rust targets system software or places where efficiency is paramount. Python brings a powerful ecosystem of mathematical and numerical libraries to bear and lends itself well to experimentation and prototyping. And TypeScript of course runs natively on browsers and the web and a number of other areas. And all of them, at least if setup properly, offer strong static typing and the easy use of dependencies. Let’s walk through the argument point by point.&lt;/p&gt;
  7128. &lt;h3&gt;AI is moving us towards &lt;em&gt;idea-oriented programming&lt;/em&gt;&lt;/h3&gt;
  7129. &lt;p&gt;Building with an LLM is presently a rather uneven experience, but I think the long-term trend is clear enough. We are seeing a shift towards a new programming paradigm. Dave Herman and I have recently taken to calling it &lt;strong&gt;idea-oriented programming&lt;/strong&gt;. As the name suggests, &lt;em&gt;idea-oriented programming&lt;/em&gt; is &lt;em&gt;programming where you are focused first and foremost on &lt;strong&gt;ideas&lt;/strong&gt; behind your project&lt;/em&gt;.&lt;/p&gt;
  7130. &lt;p&gt;Why do I say &lt;em&gt;idea-oriented programming&lt;/em&gt; and not &lt;em&gt;vibe coding&lt;/em&gt;? To me, they are different beasts. Vibe coding suggests a kind of breezy indifference to the specifics – kind of waving your hand vaguely at the AI and saying “do something like this”.
  7131. That smacks of &lt;a href=&quot;https://smallcultfollowing.com/babysteps/blog/2025/07/24/collaborative-ai-prompting/&quot;&gt;treating the AI like a genie&lt;/a&gt; – or perhaps a servant, neither of which I think is useful.&lt;/p&gt;
  7132. &lt;h3&gt;Idea-oriented programming is very much &lt;strong&gt;programming&lt;/strong&gt;&lt;/h3&gt;
  7133. &lt;p&gt;Idea-oriented programming, in contrast, is definitely &lt;strong&gt;programming&lt;/strong&gt;. But your role is different. As the programmer, you’re more like the chief architect. Your coding tools are like your apprentices. You are thinking about the goals and the key aspects of the design. You lay out a crisp plan and delegate the heavy lifting to the tools – and then you review their output, making tweaks and, importantly, generalizing those tweaks into persistent principles. When some part of the problem gets tricky, you are rolling up your sleeves and do some hands-on debugging and problem solving.&lt;/p&gt;
  7134. &lt;p&gt;If you’ve been in the industry a while, this description will be familiar. It’s essentially the role of a Principal Engineer. It’s also a solid description of what I think an open-source mentor ought to do.&lt;/p&gt;
  7135. &lt;h3&gt;Idea-oriented programming changes the priorities for language choice&lt;/h3&gt;
  7136. &lt;p&gt;In the past, when I built software projects, I would default to Rust. It’s not that Rust is the best choice for everything. It’s that I know Rust best, and so I move the fastest when I use it. I would only adopt a different language if it offered a compelling advantage (or of course if I just wanted to try a new language, which I do enjoy).&lt;/p&gt;
  7137. &lt;p&gt;But when I’m buiding things with an AI assistant, I’ve found I think differently. I’m thinking more about what libraries are available, what my fundamental performance needs are, and what platforms I expect to integrate with. I want things to be as straightforward and high-level as I can get them, because that will give the AI the best chance of success and minimize my need to dig in. The result is that I wind up with a mix of Python (when I want access to machine-learning libraries), TypeScript (when I’m building a web app, VSCode Extension, or something else where the native APIs are in TypeScript), and Rust otherwise.&lt;/p&gt;
  7138. &lt;p&gt;Why Rust as the default? Well, I like it of course, but more importantly I know that its type system will catch errors up front and I know that its overall design will result in performant code that uses relatively little memory. If I am then going to run that code in the cloud, that will lower my costs, and if I’m running it on my desktop, it’ll give more RAM for Microsoft Outlook to consume.&lt;sup id=&quot;fnref:1&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:1&quot;&gt;1&lt;/a&gt;&lt;/sup&gt;&lt;/p&gt;
  7139. &lt;h3&gt;Type systems are hugely important for idea-oriented programming&lt;/h3&gt;
  7140. &lt;p&gt;LLMs kind of turn the tables on what we expect from a computer. Typical computers can cross-reference vast amounts of information and perform deterministic computations lightning fast, but falter with even a whiff of ambiguity. LLMs, in contrast, can be surprisingly creative and thoughtful, but they have limited awareness of things that are not right in front of their face, unless they correspond to some pattern that is ingrained from training. They’re a lot more like humans that way. And the technologies we have for dealing with that, like RAG or memory MCP servers, are mostly about trying to put things in front of their face that they might find useful.&lt;/p&gt;
  7141. &lt;p&gt;But of course programmers have evolved a way to cope with human’s narrow focus: type systems, and particularly advanced type systems. Basic type systems catch small mistakes, like arguments of the wrong type. But more advanced type systems, like the ones in Rust and TypeScript, also capture domain knowledge and steer you down a path of success: using a Rust enum, for example, captures both which state your program is in and the data that is relevant to that state. This means that you can’t accidentally read a field that isn’t relevant at the moment. This is important for you, but it’s even more important for your AI collaborator(s), because they don’t have the comprehensive memory that you do, and are quite unlikely to remember those kind of things.&lt;/p&gt;
  7142. &lt;p&gt;Notably, Rust, TypeScript, and Python all have pretty decent type systems. For Python you have to set things up to use mypy and pydantic.&lt;/p&gt;
  7143. &lt;h3&gt;Ecosystems and package managers are more important than ever&lt;/h3&gt;
  7144. &lt;p&gt;Ecosystems and package managers are also hugely important to idea-oriented programming. Of course, having a powerful library to build on has always been an accellerator, but it also used to come with a bigger downside, because you had to take the time to get fluent in how the library works. That is much less of an issue now. For example, I have been building a &lt;a href=&quot;https://github.com/nikomatsakis/www.family-tree/&quot;&gt;family tree application&lt;/a&gt;&lt;sup id=&quot;fnref:2&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:2&quot;&gt;2&lt;/a&gt;&lt;/sup&gt; to use with my family. I wanted to add graphical rendering. I talked out the high-level ideas but I was able to lean on Claude to manage the use of the d3 library – it turned out beautifully!&lt;/p&gt;
  7145. &lt;p&gt;Notably, Rust, TypeScript, and Python all have pretty decent package managers – &lt;code&gt;cargo&lt;/code&gt;, &lt;code&gt;npm&lt;/code&gt;, and &lt;code&gt;uv&lt;/code&gt; respectively (both TS and Python have other options, I’ve not evaluated those in depth).&lt;/p&gt;
  7146. &lt;h3&gt;Syntactic papercuts and non-obvious workarounds matter less, but error messages and accurate guidance are still important&lt;/h3&gt;
  7147. &lt;p&gt;In 2016, Aaron Turon and I gave a &lt;a href=&quot;https://www.youtube.com/watch?v=pTQxHIzGqFI&quot;&gt;RustConf keynote&lt;/a&gt; advocating for the &lt;a href=&quot;https://blog.rust-lang.org/2017/03/02/lang-ergonomics/&quot;&gt;Ergonomics Initiative&lt;/a&gt;. Our basic point was that there were (and are) a lot of errors in Rust that are simple to solve – but only if you know the trick. If you don’t know the trick, they can be complete blockers, and can lead you to abandon the language altogether, even if the answer to your problem was just add a &lt;code&gt;*&lt;/code&gt; in the right place.&lt;/p&gt;
  7148. &lt;p&gt;In Rust, we’ve put a lot of effort into addressing those, either by changing the language or, more often, by changing our error messages to guide you to success. What I’ve observed is that, with Claude, the calculus is different. Some of these mistakes it simply never makes. Others it makes but then, based on the error message, is able to quickly corret. And this is fine. If I were writing the code by hand, I get annoyed having to apply the same repetitive changes over and over again (add &lt;code&gt;mut&lt;/code&gt;, ok, no, take it away, etc etc). But if Claude is doing, I don’t care so much, and maybe I get some added benefit – e.g., now I have a clearer indicating of which variables are declared as &lt;code&gt;mut&lt;/code&gt;.&lt;/p&gt;
  7149. &lt;p&gt;But all of this only works if Claude &lt;em&gt;can&lt;/em&gt; fix the problems – either because it knows from training or because the errors are good enough to guide it to success. One thing I’m very interested in, though, is that I think we now have more room to give ambiguous guidance (e.g., here are 3 possible fixes, but you have to decide which is best), and have the LLM navigate it.&lt;/p&gt;
  7150. &lt;h3&gt;Bottom line: LLMs makes powerful tools more accessible&lt;/h3&gt;
  7151. &lt;p&gt;The bottom line is that what enables ideas-oriented programming isn’t anything fundamentally &lt;em&gt;new&lt;/em&gt;. But previously to work this way you had to be a Principal Engineer at a big company. In that case, you could let junior engineers sweat it out, reading the docs, navigating the error messages. Now the affordances are all different, and that style of work is much more accessible.&lt;/p&gt;
  7152. &lt;p&gt;Of course, this does raise some questions. Part of what makes a PE a PE is that they have a wealth of experience to draw on. Can a young engineer do that same style of work? I think yes, but it’s going to take some time to find the best way to teach people that kind of judgment. It was never possible before because the tools weren’t there.&lt;/p&gt;
  7153. &lt;p&gt;It’s also true that this style of working means you spend less time in that “flow state” of writing code and fitting the pieces together. Some have said this makes coding “boring”. I don’t find that to be true. I find that I can have a very similar – maybe even better – experience by brainstorming and designing with Claude, writing out my plans and RFCs. A lot of the tedium of that kind of ideation is removed since Claude can write up the details, and I can focus on how the big pieces fit together. But this too is going to be an area we explore more over time.&lt;/p&gt;
  7154. &lt;div class=&quot;footnotes&quot;&gt;

  7158. &lt;p&gt;Amazon is migrating to M365, but at the moment, I still receive my email via a rather antiquated Exchange server. I count it a good day if the mail is able to refresh at least once that day, usually it just stalls out. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:1&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;

  7161. &lt;p&gt;My family bears a striking resemblance to the family in My Big Fat Greek Wedding. There are many relatives that I consider myself very close to and yet have basically no idea how we are &lt;em&gt;actually&lt;/em&gt; related (well, I didn’t, until I setup my family tree app). &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:2&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;

  7168. <title>Mozilla Thunderbird: State of the Thunder: Answering Community Questions!</title>
  7169. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3636</guid>
  7170. <link>https://blog.thunderbird.net/2025/07/state-of-the-thunder-answering-community-questions/</link>
  7171. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/Blog-banner-State-of-the-Thunder4-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  7172. &lt;p&gt;For the past few months, we’ve been talking about our roadmaps and development and answering community questions in a &lt;a href=&quot;https://www.youtube.com/playlist?list=PLMY3ZzVsXXyqSVZHS10hold60Uqb97xzD&quot;&gt;video&lt;/a&gt; and &lt;a href=&quot;https://thundercast.transistor.fm/&quot;&gt;podcast&lt;/a&gt; series we call “&lt;a href=&quot;https://thunderbird.topicbox.com/groups/planning/T55693d19637759ef/state-of-the-thunder-volume-2&quot;&gt;State of the Thunder.&lt;/a&gt;” We’ve decided, after your feedback, to also cover them in a blog, for those who don’t have time to watch or listen to the entire session. &lt;/p&gt;
  7173.  
  7174.  
  7175.  
  7176. &lt;p&gt;This session is focused on answering inquiries from the community, and we’ve got the questions and summaries of the answers (with helpful links to resources we mentioned)! This series runs every two weeks, and we’ll be creating blogs from here on in. If you have any questions you’d like answered, please feel free to include them in the comments! &lt;/p&gt;
  7177.  
  7178.  
  7179.  
  7180. &lt;h3&gt;Supporting and Sustaining FOSS Projects We Use&lt;/h3&gt;
  7181.  
  7182.  
  7183.  
  7184. &lt;p&gt;&lt;strong&gt;Question: &lt;/strong&gt;As we move toward having more traditionally commercial offerings with services that are built on top of other projects, what is our plan in helping those projects’ maintenance (and financial) sustainability? If we find a good model, can we imagine extending it to our apps, too?&lt;/p&gt;
  7185.  
  7186.  
  7187.  
  7188. &lt;p&gt;&lt;strong&gt;Answer&lt;/strong&gt;: Right now, the only project we’re using to help build Thunderbird Pro is &lt;a href=&quot;https://stalw.art/&quot;&gt;Stalwart&lt;/a&gt;, and we’ll have more details on how we’re using it soon. But we absolutely want to make sure the project gets financial support from us to support its sustainability and well-being. We want to play nice!&lt;/p&gt;
  7189.  
  7190.  
  7191.  
  7192. &lt;p&gt;Appointment and Assist are from scratch, and Send is from &lt;a href=&quot;https://github.com/mozilla/send&quot;&gt;old Firefox code&lt;/a&gt;, and so there isn’t another project to support with those. But to go back to a point Ryan Sipes has frequently made, while people can use all of these tools for free by self-hosting, they can subscribe as a way of both simplifying their usage and making sure these projects are supported for regular maintenance and a long life.&lt;/p&gt;
  7193.  
  7194.  
  7195.  
  7196. &lt;h3&gt;Future UI Settings Plans&lt;/h3&gt;
  7197.  
  7198.  
  7199.  
  7200. &lt;p&gt;&lt;strong&gt;Question: &lt;/strong&gt;The interface is difficult to customize but more importantly is difficult to discover all the options available because they’re scattered around settings, account settings, top menu bar, context menus, etc. 140 Introduced the Appearance section in the settings, any plans to continue this effort with some more drastic restructuring of the UI?&lt;/p&gt;
  7201.  
  7202.  
  7203.  
  7204. &lt;p&gt;&lt;strong&gt;Answer: &lt;/strong&gt;Yes, we do have plans! We know the existing UI isn’t the most welcoming, since it is so powerful and we don’t want to overwhelm users with every option they can configure. We have a roadmap that’s almost ready to share that involves restructuring Account Settings. Right now, individual settings are very scattered, and we want to group things together into related sections that can all be changed at the same time. We want to simplify discoverability to make it easier to customize Thunderbird without digging into the config panel.&lt;/p&gt;
  7205.  
  7206.  
  7207.  
  7208. &lt;h3&gt;Account Setup and Manual Configuration&lt;/h3&gt;
  7209.  
  7210.  
  7211.  
  7212. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Using manual configuration during email setup has become more difficult with time with the prioritization of email autoconfiguration.&lt;/p&gt;
  7213.  
  7214.  
  7215.  
  7216. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; Unfortunately, manual setup has confused a lot of casual users, which is why we’ve prioritized autodiscovery and autosetup. We’ve done a lot of exploration and testing with our Design team, and in turn they’ve done a lot of discussion and testing with our community. You can see some of these conversations in our &lt;a href=&quot;https://thunderbird.topicbox.com/groups/ux&quot;&gt;UX mailing list&lt;/a&gt;. And even if you have to start the process, there is a link in it to edit the configuration manually. Ultimately, we have to have a balance between less technical and more technical users, and to be as usable and approachable as we can to the former.&lt;/p&gt;
  7217.  
  7218.  
  7219.  
  7220. &lt;h3&gt;Balancing Complexity and Simplicity&lt;/h3&gt;
  7221.  
  7222.  
  7223.  
  7224. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Thunderbird is powerful with a lot of options but it should have more. Any plans to integrate ImportExportTools  (and other add-ons) and add more functionalities?&lt;/p&gt;
  7225.  
  7226.  
  7227.  
  7228. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; &lt;a href=&quot;https://addons.thunderbird.net/&quot;&gt;Thunderbird’s Add-ons&lt;/a&gt; are often meant for users who like more complexity! When we tackle this question, there’s two issues that come to mind. First, several developers get financial support from their users, and we want to be mindful of that. Second is the eternal question of how many features are too many features? We already have this issue in feedback between “Thunderbird doesn’t have enough features” and “Thunderbird is too complicated!” Every feature we add gives us more technical debt. If we bring an add-on into core, we can support it for the long term.&lt;/p&gt;
  7229.  
  7230.  
  7231.  
  7232. &lt;p&gt;We think this question may also come from the fact that Add-ons often “break” with each ESR release. But we’re trying to find ways to support developers to use the API to increase compatibility. We’re also considering how we can financially support Add-on developers to help them maintain their apps. Our core developers are pressed for time, and so we’re beyond grateful to the Add-on developers who can make Thunderbird stronger and more specialized than we could on our own!&lt;/p&gt;
  7233.  
  7234.  
  7235.  
  7236. &lt;h3&gt;Benefits of the New Monthly Release Channel&lt;/h3&gt;
  7237.  
  7238.  
  7239.  
  7240. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Is the new Release channel with monthly versions working properly and bringing any benefits?&lt;/p&gt;
  7241.  
  7242.  
  7243.  
  7244. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; Yes, on both counts! Right now, we have 10 to 20 percent of Thunderbird desktop users on the Release channel. While we don’t have hard numbers for the benefits YET, we’d love to get some numbers on improvements in bug reactivity and other indicators. We noticed this year’s ESR had far fewer bugs, which probably owed to Release users testing new features. While we’ve always had Beta users, we have so many more people on Release. So if something went wrong, we could fix it, let it “ride the train,” and have the fix in the next version. &lt;/p&gt;
  7245.  
  7246.  
  7247.  
  7248. &lt;p&gt;And our developers have stopped wondering when our features will make it to users! Things will be in users’ hands in a month, versus nearly a year for some features.&lt;/p&gt;
  7249.  
  7250.  
  7251.  
  7252. &lt;h3&gt;JMAP Support in Thunderbird&lt;/h3&gt;
  7253.  
  7254.  
  7255.  
  7256. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Any plans on supporting JMAP?&lt;/p&gt;
  7257.  
  7258.  
  7259.  
  7260. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; 100% yes. Though JMAP is still something of a niche protocol, with doesn’t yet have widespread support from major providers. But now, with Thundermail we’ll be our own provider, and it will come with JMAP. Also, with the upcoming iOS app, it will be easy to add support for JMAP. First, we’re making the app from scratch so we have no technical debt. Second, we can do things properly from the start and be protocol agnostic.&lt;/p&gt;
  7261.  
  7262.  
  7263.  
  7264. &lt;p&gt;Also, we’ve taken several lessons from our Exchange implementation, namely how to implement a new protocol properly. This will help us add support for JMAP faster.&lt;/p&gt;
  7265.  
  7266.  
  7267.  
  7268. &lt;h3&gt;Maintaining Backups in Thunderbird&lt;/h3&gt;
  7269.  
  7270.  
  7271.  
  7272. &lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; I have used Thunderbird since its first release and I always wondered how to properly and safely maintain backups of local emails. No matter how much I hate Outlook it offers built-in backup archives of .pst files that can be moved to other installations. The closest thing in Thunderbird is to copy the entire profile folder, but that comes with many more unpredictable outcomes. &lt;/p&gt;
  7273.  
  7274.  
  7275.  
  7276. &lt;p&gt;I might be asking for something uncommon but I manage many projects with a very heavy communication flow between multiple clients, and  when the project is completed I like to export the project folder with all the messages into a single PST file and create a couple of back-ups for safety, so no matter if my email server has problems, or the emails on my server and computer are accidentally deleted, I have that folder back-up as a single file which I can import into a new installation.&lt;/p&gt;
  7277.  
  7278.  
  7279.  
  7280. &lt;p&gt;&lt;strong&gt;Answer:&lt;/strong&gt; We’d love for anyone with this question to come talk to us about how to improve our Import/Export tools. Unfortunately, there’s no universal email archive format, and a major issue is that Outlook’s backup files are in a proprietary format. We’ve rebuilt the Import/Export UI and done a bit on the backend. Alas, this is all we’ve had time for. &lt;/p&gt;
  7281.  
  7282.  
  7283.  
  7284. &lt;p&gt;So, if you’d like to help us tackle this problem, come chat with us! You can find us &lt;a href=&quot;https://matrix.to/#/%23thunderbird:mozilla.org&quot;&gt;on Matrix&lt;/a&gt; and in the &lt;a href=&quot;https://thunderbird.topicbox.com/groups/developers&quot;&gt;Developers&lt;/a&gt; and &lt;a href=&quot;https://thunderbird.topicbox.com/groups/planning&quot;&gt;Planning&lt;/a&gt; mailing lists. We think there’s definitely room &lt;a href=&quot;https://xkcd.com/927&quot;&gt;for a standard&lt;/a&gt; around email backups.&lt;/p&gt;

  7308. <title>Mozilla Privacy Blog: Open by Design: How Nations Can Compete in the Age of AI</title>
  7309. <guid isPermaLink="false">https://blog.mozilla.org/netpolicy/?p=2489</guid>
  7310. <link>https://blog.mozilla.org/netpolicy/2025/07/30/open-by-design-how-nations-can-compete-in-the-age-of-ai/</link>
  7311. <description>&lt;p&gt;The choices governments make today, about who gets to build, access and benefit from AI, will shape economic competitiveness, national security and digital rights for decades.&lt;/p&gt;
  7312. &lt;p&gt;A new report by UK think tank, Demos, supported by Mozilla, makes the case that if the UK wants to thrive in the AI era it must embrace openness. And while the report is tailored to the UK context, its implications reach far beyond Westminster.&lt;/p&gt;
  7313. &lt;p&gt;Unlike the US or China, the UK and many other countries cannot outspend or outscale on AI, but they can out-collaborate. Demos’ report &lt;a href=&quot;https://demos.co.uk/research/the-open-dividend-building-an-ai-openness-strategy-to-unlock-the-uks-ai-potential/&quot;&gt;&lt;i&gt;The Open Dividend: Building an AI openness strategy to unlock the UK’s AI potential&lt;/i&gt;&lt;/a&gt;, argues that making key AI resources – models, datasets, compute and safety tools, more openly accessible can spur innovation, lower the costs of AI adoption, enable safer and more transparent development, boost digital sovereignty and align AI more closely with public value. A recipe, if there ever was one, for ‘winning’ at AI.&lt;/p&gt;
  7314. &lt;p&gt;The wider market certainly reflects these trends – the AI sector is shifting toward value accruing in smaller, specialised and more efficient models. Developments all spurred on by open source innovation. But this also means open models aren’t just more accessible and customisable, they’re becoming more capable too.&lt;/p&gt;
  7315. &lt;p&gt;This echoes another recent study Mozilla supported, this time &lt;a href=&quot;https://www.mckinsey.com/capabilities/quantumblack/our-insights/open-source-technology-in-the-age-of-ai&quot;&gt;a survey of more than 700 businesses conducted by McKinsey&lt;/a&gt;. Among its top findings – 50% of respondents are already leveraging an open source solution across their stack. More than three-quarters reported that they intended to grow this usage. Most significantly, the first movers – organisations that see AI as vital to their future competitive advantage – are more than 40% more likely to use open source models and tools than respondents from other organisations. Similar research just published by the &lt;a href=&quot;https://www.linuxfoundation.org/blog/open-source-ai-is-transforming-the-economy&quot;&gt;Linux Foundation&lt;/a&gt; has also found openness is fast becoming a competitive edge. Demos’s report expands upon these stats – strategically utilising openness in AI is not just about sharing code, it’s about shaping a more resilient and prosperous ecosystem.&lt;/p&gt;
  7316. &lt;p&gt;The risks of centralisation are well known and global. We have seen it before with the development of the internet. If we let AI ecosystems become concentrated, so that all power remains in the hands of a few firms and their proprietary models, this will make it much harder to ensure AI serves people – rather than the other way around. It also raises more urgent concerns about market dominance, bias, surveillance, and national resilience.&lt;/p&gt;
  7317. &lt;p&gt;If we want AI to serve humanity, we all have a stake in getting this right.&lt;/p&gt;
  7318. &lt;p&gt;As the Demos report argues, openness isn’t just a value – it’s a strategy. We were proud to support the development of this timely report – read it &lt;a href=&quot;https://demos.co.uk/research/the-open-dividend-building-an-ai-openness-strategy-to-unlock-the-uks-ai-potential/&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;

  7324. <title>Mozilla Thunderbird: Welcoming New Faces to the Thunderbird Community Team</title>
  7325. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3629</guid>
  7326. <link>https://blog.thunderbird.net/2025/07/welcoming-new-faces-to-the-thunderbird-community-team/</link>
  7327. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/community-blog-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  7328. &lt;h3&gt;&lt;strong&gt;Community First&lt;/strong&gt;&lt;/h3&gt;
  7329.  
  7330.  
  7331.  
  7332. &lt;p&gt;Thunderbird is (and has always been) powered by the people. The project exists because of the amazing community of passionate code contributors, bug-bashers, content creators, and all-around wonderful humans who have stood behind it and worked to support and maintain it over the years.&lt;/p&gt;
  7333.  
  7334.  
  7335.  
  7336. &lt;p&gt;And as the Thunderbird community grows, we want to ensure that we [the team supporting you] grow alongside you, so that we can continue to collaborate and build effectively and efficiently together. &lt;/p&gt;
  7337.  
  7338.  
  7339.  
  7340. &lt;p&gt;That’s why we’re thrilled to announce a refreshed and growing Thunderbird Community Team here at MZLA! Expect a little more structure, a lot more collaboration, and an open invitation to our users and contributors to join us and help shape what comes next.&lt;/p&gt;
  7341.  
  7342.  
  7343.  
  7344. &lt;h3&gt;&lt;strong&gt;Meet the Team&lt;/strong&gt;&lt;/h3&gt;
  7345.  
  7346.  
  7347.  
  7348. &lt;p&gt;Whether you’re filing your first bug, searching for support, writing documentation, or just dropping into Matrix to say hi, this is the team working hard behind the scenes to make sure your experience is productive, constructive, and superconductive:&lt;/p&gt;
  7349.  
  7350.  
  7351.  
  7352. &lt;h4&gt;&lt;strong&gt;Michael Ellis | Manager of Community Programs&lt;/strong&gt;&lt;/h4&gt;
  7353.  
  7354.  
  7355.  
  7356. &lt;p&gt;Hey there! I’m Michael, and I’m joining the Thunderbird family as Manager of Community Programs to help grow and support our awesome community. I’ll be working on programs that help improve contributor pathways and make it easier for more people to get involved in the work we do and the decisions we make on a day-to-day basis.&lt;/p&gt;
  7357.

  7360. &lt;p&gt;I come from a background of managing developer communities and running large-scale programs at organizations like Mozilla, Ionic, and NXP Semiconductors. I believe open-source communities are strongest when they’re welcoming, engaging, and well-supported. I like gifs and memes very much. &lt;/p&gt;
  7361.  
  7362.  
  7363.  
  7364. &lt;p&gt;I look forward to seeing you in the Thunderbird community and saying hello to one another on Matrix!  &lt;/p&gt;
  7365.  
  7366.  
  7367.  
  7368. &lt;p&gt;Until then, Keep on Rocking the Free Web!&lt;/p&gt;

  7375.  
  7376. &lt;p&gt;Greetings everyone.  Wayne here, also known as wsmwk.  I have used open source for forty years, been a user of and contributor to Thunderbird for twenty years, and am a founding member of the Thunderbird Council, and have run several of the council elections. &lt;/p&gt;
  7377.  
  7378.  
  7379.  
  7380. &lt;p&gt;I love to mentor and connect to our community members who assist Thunderbird users in &lt;a href=&quot;https://www.reddit.com/r/Thunderbird/&quot;&gt;Reddit&lt;/a&gt;, &lt;a href=&quot;https://connect.mozilla.org/t5/ideas/idb-p/ideas/label-name/thunderbird&quot;&gt;Connect&lt;/a&gt;, &lt;a href=&quot;https://matrix.to/#/#thunderbird-community:mozilla.org&quot;&gt;matrix&lt;/a&gt; (chat), &lt;a href=&quot;https://bugzilla.mozilla.org/enter_bug.cgi?product=thunderbird&quot;&gt;bugzilla&lt;/a&gt;, &lt;a href=&quot;http://github.com/thunderbird/&quot;&gt;github&lt;/a&gt;, &lt;a href=&quot;https://thunderbird.topicbox.com/groups/&quot;&gt;topicbox forums&lt;/a&gt;, &lt;a href=&quot;https://support.mozilla.org/en-US/questions/thunderbird&quot;&gt;Thunderbird support in SUMO&lt;/a&gt; (SUpport MOzilla), and &lt;a href=&quot;https://www.thunderbird.net/participate/&quot;&gt;other venues&lt;/a&gt;.  And I help manage these venues and assist users, to bring the concerns of the user community to developers.  I also assist in developing content for users (including knowledge base articles in SUMO) and assist in our general communications with users.  &lt;/p&gt;
  7381.  
  7382.  
  7383.  
  7384. &lt;p&gt;There are many ways you can participate in small ways or large, including through praise or constructive feedback through the venues listed above and those listed on our &lt;a href=&quot;https://www.thunderbird.net/participate/&quot;&gt;participate web page&lt;/a&gt; – I encourage you to do so at your convenience. And I look forward to connecting with you soon. &lt;/p&gt;

  7391.  
  7392. &lt;p&gt;Hi everyone! *waves*&lt;/p&gt;
  7393.  
  7394.  
  7395.  
  7396. &lt;p&gt;I’ve been part of the Thunderbird family for nearly two years, working with the awesome Desktop team. Now, I’m thrilled to be joining the Community team, led by Michael, where I’ll be focusing on initiatives to support and grow our amazing contributor community.&lt;/p&gt;
  7397.  
  7398.  
  7399.  
  7400. &lt;p&gt;My work will include creating helpful video content to make it easier for folks to get started, as well as improving our technical documentation at&lt;a href=&quot;https://source-docs.thunderbird.net&quot;&gt; source-docs.thunderbird.net&lt;/a&gt; and&lt;a href=&quot;https://developer.thunderbird.net/&quot;&gt; developer.thunderbird.net&lt;/a&gt;.&lt;/p&gt;
  7401.  
  7402.  
  7403.  
  7404. &lt;p&gt;If you’re interested in contributing or need help getting started, don’t hesitate to reach out to me on Matrix — I’d love to chat!&lt;/p&gt;
  7405.  
  7406.  
  7407.  
  7408. &lt;h3&gt;&lt;strong&gt;What’s the Road Ahead?&lt;/strong&gt;&lt;/h3&gt;
  7409.  
  7410.  
  7411.  
  7412. &lt;p&gt;Community is at the heart of everything Thunderbird does. As our product continues to evolve and improve, we want our community experience to keep pace with that growth. This means not only working to keep Thunderbird open, but striving towards better contributor pathways, clearer communication, and more opportunities to participate.&lt;/p&gt;
  7413.  
  7414.  
  7415.  
  7416. &lt;p&gt;We’re here to listen, collaborate, and help you succeed. You can expect to see more initiatives, experiments, and outreach from us soon, but you don’t have to wait till then to weigh in.&lt;/p&gt;
  7417.  
  7418.  
  7419.  
  7420. &lt;p&gt;Have thoughts or suggestions? Drop a comment below to share them directly, or&lt;a href=&quot;https://connect.mozilla.org/t5/discussions/have-ideas-to-improve-the-thunderbird-community/td-p/100264&quot;&gt; visit our Connect thread&lt;/a&gt; to see what others are saying and add your own ideas there. Together, we can help shape the future of the Thunderbird community and product.&lt;/p&gt;
  7421.  
  7422.  
  7423.  
  7424. &lt;p&gt;After all, Thunderbird is powered by the people, &amp;amp; that includes &lt;em&gt;you&lt;/em&gt;.&lt;/p&gt;

  7430. <title>Firefox Nightly: Copy Link to Highlight in Nightly – These Weeks in Firefox: Issue 185</title>
  7431. <guid isPermaLink="false">https://blog.nightly.mozilla.org/?p=1870</guid>
  7432. <link>https://blog.nightly.mozilla.org/2025/07/28/copy-link-to-highlight-in-nightly-these-weeks-in-firefox-issue-185/</link>
  7433. <description>&lt;h3&gt;Highlights&lt;/h3&gt;
  7434. &lt;ul&gt;
  7435. &lt;li&gt;The Text Fragments creation UI was just activated in Firefox Nightly allowing you to share/reference a link anchor to any text snippet in a page
  7436. &lt;ul&gt;
  7437. &lt;li&gt;&lt;a href=&quot;https://mastodon.social/@firefoxnightly/114805708639661562&quot;&gt;https://mastodon.social/@firefoxnightly/114805708639661562&lt;/a&gt;&lt;/li&gt;
  7438. &lt;li&gt;This is held to Nightly for now while it is tested.&lt;/li&gt;
  7439. &lt;li&gt;&lt;a href=&quot;https://blog.nightly.mozilla.org/files/2025/07/image1.png&quot;&gt;&lt;img alt=&quot;A section of a webpage displaying the text &amp;quot;Love the internet again&amp;quot; highlighted in blue. A context menu appears with the “Copy Link to Highlight” option selected, demonstrating a browser feature for linking to specific text selections.&quot; class=&quot;aligncenter size-full wp-image-1864&quot; height=&quot;180&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/07/image1.png&quot; width=&quot;976&quot; /&gt;&lt;/a&gt;&lt;/li&gt;
  7440. &lt;/ul&gt;
  7441. &lt;/li&gt;
  7442. &lt;li&gt;Thanks to volunteer contributor Christina for introducing a new browserSettings.verticalTabs API which allows extensions to determine if vertical tabs are currently enabled (or to offer to enable it for the user) – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1946600&quot;&gt;Bug 1946600&lt;/a&gt;&lt;/li&gt;
  7443. &lt;li&gt;Henrik &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1964903&quot;&gt;enabled async widget events for wheel scrolling by default in web-platform tests&lt;/a&gt; as part of &lt;a href=&quot;https://wpt.fyi/interop-2025&quot;&gt;Interop 2025&lt;/a&gt;, bringing Firefox to &lt;a href=&quot;https://wpt.fyi/results/dom/events/scrolling?label=master&amp;amp;label=experimental&amp;amp;aligned&amp;amp;view=interop&amp;amp;q=label%3Ainterop-2025-scrollend&quot;&gt;100% pass rate on scrollend-related tests&lt;/a&gt;.&lt;/li&gt;
  7444. &lt;li&gt;We’ve &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971702&quot;&gt;updated our Opera migrator so that it works again after the Opera browser changed how it stores profile data&lt;/a&gt;. This fix was uplifted to Firefox 141 which should go out to release later this month.&lt;/li&gt;
  7445. &lt;/ul&gt;
  7446. &lt;h3&gt;Friends of the Firefox team&lt;/h3&gt;
  7447. &lt;h4&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/buglist.cgi?title=Resolved%20bugs%20(excluding%20employees)&amp;amp;quicksearch=1968586%2C1972814%2C1439374%2C1974137%2C1969898%2C1928096%2C1878420&quot;&gt;Resolved bugs (excluding employees)&lt;/a&gt;&lt;/h4&gt;

  7454. &lt;h5&gt;Addon Manager &amp;amp; about:addons&lt;/h5&gt;
  7455. &lt;ul&gt;
  7456. &lt;li&gt;Fixed XPIProvider.processPendingFileChanges logic to not emit unnecessary warnings for locations with non-existing staging extensions subdirs while processing staged add-on installations – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974233&quot;&gt;Bug 1974233&lt;/a&gt;&lt;/li&gt;
  7457. &lt;li&gt;Fixed downloaded XPI files not deleted when add-on install flow is cancelled – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1639163&quot;&gt;Bug 1639163&lt;/a&gt;&lt;/li&gt;
  7458. &lt;li&gt;Fixed Windows-specific crash on nsIFile::Contains called with a null path while writing the addon startup data to the extensions.json profile file –  &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1975674&quot;&gt;Bug 1975674&lt;/a&gt;&lt;/li&gt;
  7459. &lt;li&gt;Removed old internal privileged helper nsIComponentManager.addBootstrappedManifestLocation – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1953136&quot;&gt;Bug 1953136&lt;/a&gt;&lt;/li&gt;
  7460. &lt;/ul&gt;
  7461. &lt;h5&gt;WebExtensions Framework&lt;/h5&gt;
  7462. &lt;ul&gt;
  7463. &lt;li&gt;Thanks to Nathan Teodosio for contributing end-to-end test coverage for the native messaging API exercised from a Firefox build running inside the snap package sandbox – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1928096&quot;&gt;Bug 1928096&lt;/a&gt;&lt;/li&gt;
  7464. &lt;/ul&gt;
  7465. &lt;h4&gt;DevTools&lt;/h4&gt;
  7466. &lt;ul&gt;
  7467. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=559949&quot;&gt;Julian Descottes [:jdescottes]&lt;/a&gt; fixed an issue with StyleEditor pretty printing where we were adding blank lines when last declaration missed a semi colon (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974450&quot;&gt;#1974450&lt;/a&gt;)&lt;/li&gt;
  7468. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=559949&quot;&gt;Julian Descottes [:jdescottes]&lt;/a&gt; made User agent stylesheets read-only in the style editor (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972844&quot;&gt;#1972844&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974395&quot;&gt;#1974395&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973508&quot;&gt;#1973508&lt;/a&gt;)
  7469. &lt;ul&gt;
  7470. &lt;li&gt;&lt;a href=&quot;https://blog.nightly.mozilla.org/files/2025/07/image2.png&quot;&gt;&lt;img alt=&quot;Screenshot of the Firefox Developer Tools Style Editor panel showing a list of loaded CSS stylesheets. The list includes css with 4 rules, console-test-app.css with 11 rules, ua.css with 63 rules (highlighted in blue and locked as read-only), and html.css with 172 rules (also locked). A “Save” option is shown for ua.css.&quot; class=&quot;aligncenter size-full wp-image-1865&quot; height=&quot;394&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/07/image2.png&quot; width=&quot;484&quot; /&gt;&lt;/a&gt;&lt;/li&gt;
  7471. &lt;/ul&gt;
  7472. &lt;/li&gt;
  7473. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=557153&quot;&gt;Nicolas Chevobbe [:nchevobbe]&lt;/a&gt; added lock icon for rules in uneditable stylesheets in Rules view to be consistent and improve accessibility (we were only adding a subtle grey background, and UI state shouldn’t be conveyed with colors only (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973935&quot;&gt;#1973935&lt;/a&gt;)
  7474. &lt;ul&gt;
  7475. &lt;li&gt;&lt;a href=&quot;https://blog.nightly.mozilla.org/files/2025/07/image3.png&quot;&gt;&lt;img alt=&quot;Firefox Developer Tools screenshot showing a CSS rule for the :root selector from the user agent stylesheet ua.css at line 393. The rule sets color: CanvasText; and view-transition-name: root;. A lock icon indicates the rule is read-only.&quot; class=&quot;aligncenter size-full wp-image-1866&quot; height=&quot;124&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/07/image3.png&quot; width=&quot;660&quot; /&gt;&lt;/a&gt;&lt;/li&gt;
  7476. &lt;/ul&gt;
  7477. &lt;/li&gt;
  7478. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=557153&quot;&gt;Nicolas Chevobbe [:nchevobbe]&lt;/a&gt; improved Inspector markup search by highlighting results and scrolling to the first matching range (the match can be deep inside a text node) (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1259390&quot;&gt;#1259390&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1440229&quot;&gt;#1440229&lt;/a&gt;)
  7479. &lt;ul&gt;
  7480. &lt;li&gt;&lt;a href=&quot;https://blog.nightly.mozilla.org/files/2025/07/image4.png&quot;&gt;&lt;img alt=&quot;Screenshot of Firefox Developer Tools showing the HTML structure of a section titled &amp;quot;Afficher votre soutien.&amp;quot; The highlighted element contains French text emphasizing the importance of a better Internet, with multiple instances of the word &amp;quot;Internet&amp;quot; highlighted in yellow and the full paragraph selected in blue. The Inspector tab is active, with search results indicating 8 of 19 matches for the term &amp;quot;Internet.&amp;quot;&quot; class=&quot;aligncenter size-full wp-image-1867&quot; height=&quot;626&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/07/image4.png&quot; width=&quot;850&quot; /&gt;&lt;/a&gt;&lt;/li&gt;
  7481. &lt;/ul&gt;
  7482. &lt;/li&gt;
  7483. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=283262&quot;&gt;Alexandre Poirot [:ochameau]&lt;/a&gt; made parent process modules visible when debugging Firefox for Android (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973939&quot;&gt;#1973939&lt;/a&gt;)&lt;/li&gt;
  7484. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=559949&quot;&gt;Julian Descottes [:jdescottes]&lt;/a&gt; fixed an issue in the Netmonitor Cache panel, who could be empty even when the response was cached (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973036&quot;&gt;#1973036&lt;/a&gt;)&lt;/li&gt;
  7485. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=559949&quot;&gt;Julian Descottes [:jdescottes]&lt;/a&gt; fixed displaying base 64 images in the Response panel and added a checkered background behind so they’re always visible (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1975429&quot;&gt;#1975429&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1975664&quot;&gt;#1975664&lt;/a&gt;)&lt;/li&gt;
  7486. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=559949&quot;&gt;Julian Descottes [:jdescottes]&lt;/a&gt; added a mach devtools-node-test command to run devtools node tests (documentation: &lt;a href=&quot;https://firefox-source-docs.mozilla.org/devtools/tests/node-tests.html&quot;&gt;https://firefox-source-docs.mozilla.org/devtools/tests/node-tests.html&lt;/a&gt;)&lt;/li&gt;
  7487. &lt;/ul&gt;
  7488. &lt;h4&gt;WebDriver BiDi&lt;/h4&gt;
  7489. &lt;ul&gt;
  7490. &lt;li&gt;Sabina &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1969898&quot;&gt;renamed Proxy capability class to ProxyConfiguration&lt;/a&gt; to avoid confusion with JavaScript Proxy class.&lt;/li&gt;
  7491. &lt;li&gt;Baku &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974394&quot;&gt;fixed a regression&lt;/a&gt; where adding a cookie through the WebDriver BiDi or Marionette APIs would fail with an error if the expiry value exceeded 400 days.&lt;/li&gt;
  7492. &lt;li&gt;Sasha updated &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971488&quot;&gt;the WebDriver BiDi cookie APIs to support “default” value in “sameSite” property&lt;/a&gt; to address recent changes in platform API which wouldn’t allow anymore to set “sameSite” equal ”none” and “secure” equals “false” on HTTPS pages.&lt;/li&gt;
  7493. &lt;li&gt;Bvandersloot added &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972830&quot;&gt;support in Marionette for interacting with CHIPS cookies&lt;/a&gt; (Cookies Having Independent Partitioned State).&lt;/li&gt;
  7494. &lt;li&gt;Bas &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974262&quot;&gt;fixed the mach command for firefox-ui-functional tests&lt;/a&gt;, which now works again when run without specifying a manifest or test path.&lt;/li&gt;
  7495. &lt;li&gt;Henrik &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1955007&quot;&gt;removed the temporary remote.system-access-check.enabled preference&lt;/a&gt; in Firefox 141. This preference can no longer be used to disable system access checks when using WebDriver in Firefox’s chrome scope during testing.&lt;/li&gt;
  7496. &lt;/ul&gt;
  7497. &lt;h4&gt;Lint, Docs and Workflow&lt;/h4&gt;
  7498. &lt;ul&gt;
  7499. &lt;li&gt;Gijs landed a change to make the ESLint rule no-comparison-or-assignment-inside-ok work for Assert.ok() – previously it only worked for ok().&lt;/li&gt;
  7500. &lt;/ul&gt;
  7501. &lt;h4&gt;New Tab Page&lt;/h4&gt;
  7502. &lt;ul&gt;
  7503. &lt;li&gt;Special thanks to Jules who has been helping us get New Tab using design tokens / design system colours! &lt;a href=&quot;https://firefoxux.github.io/arewedesigntokensyet/browser/extensions/newtab/css/&quot;&gt;New Tab is now at 84.22% propagation!&lt;/a&gt;&lt;/li&gt;
  7504. &lt;li&gt;Special thanks to rpl &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973228&quot;&gt;who has been plugging away at a fairly impressive stack of patches which will let us deploy trainhop updates for newtab via Nimbus / Experimenter&lt;/a&gt;!&lt;/li&gt;
  7505. &lt;li&gt;Nathan landed work related to a &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1965906&quot;&gt;TrendingSearches widget&lt;/a&gt; which will run in an upcoming experiment&lt;/li&gt;
  7506. &lt;li&gt;Nathan also recently landed a fix that should help us avoid &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974328&quot;&gt;overlapping / overabundance of messages between New Tab and the rest of the browser&lt;/a&gt;.&lt;/li&gt;
  7507. &lt;li&gt;mconley &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1974803&quot;&gt;posted a patch to add a moz-ohttp-image protocol handler&lt;/a&gt; to, in theory, request images privately over OHTTP, for use on newtab under certain circumstances.&lt;/li&gt;
  7508. &lt;/ul&gt;
  7509. &lt;h4&gt;Places&lt;/h4&gt;
  7510. &lt;ul&gt;
  7511. &lt;li&gt;Lazily loading `PlacesSemanticHistoryManager` (Standard8).&lt;/li&gt;
  7512. &lt;li&gt;Refactoring `PlacesQuery.sys.mjs` to split query and cache logic (James).&lt;/li&gt;
  7513. &lt;li&gt;Still trying to see if lowercasing tokens before SQL improves performance for `MatchAutoCompleteFunction` (James).&lt;/li&gt;
  7514. &lt;li&gt;Landed a simple patch that removed other Places expiration heuristics (James).&lt;/li&gt;
  7515. &lt;li&gt;Fixing unit tests for `History.fetch` returning referrer URI (James).&lt;/li&gt;
  7516. &lt;li&gt;Working on using `ConcurrentConnection` for favicon protocol handlers (Yazan).&lt;/li&gt;
  7517. &lt;li&gt;Looking into a memory leak in recent Favicons code (Marco).&lt;/li&gt;
  7518. &lt;/ul&gt;
  7519. &lt;h4&gt;Search and Navigation&lt;/h4&gt;
  7520. &lt;ul&gt;
  7521. &lt;li&gt;Unit Converter &amp;amp; Calculator
  7522. &lt;ul&gt;
  7523. &lt;li&gt;Landed a fix for incorrect unit conversions with long numbers (Yazan).&lt;/li&gt;
  7524. &lt;li&gt;A fix is in review for negative calculator results displaying wrong in RTL builds (Yazan).&lt;/li&gt;
  7525. &lt;li&gt;Landed a fix for negative converted results displaying wrong in RTL builds (Yazan).&lt;/li&gt;
  7526. &lt;/ul&gt;
  7527. &lt;/li&gt;
  7528. &lt;li&gt;Unified Trust Panel
  7529. &lt;ul&gt;
  7530. &lt;li&gt;Reviews on initial implementation are done, about to land behind `browser.urlbar.trustPanel.featureGate` pref (Dale).&lt;/li&gt;
  7531. &lt;/ul&gt;
  7532. &lt;/li&gt;
  7533. &lt;li&gt;Semantic History Search (Marco)
  7534. &lt;ul&gt;
  7535. &lt;li&gt;Sorted general results by frecency, including semantic.&lt;/li&gt;
  7536. &lt;li&gt;Added telemetry for the database file size.&lt;/li&gt;
  7537. &lt;li&gt;Added `available_semantic_sources` property to abandonment and engagement.&lt;/li&gt;
  7538. &lt;li&gt;Added semantic history chunks calculation telemetry.&lt;/li&gt;
  7539. &lt;li&gt;Working on distinguishing semantic and SERP history in telemetry events.&lt;/li&gt;
  7540. &lt;li&gt;Next up: improving results quality (decreasing distance threshold, removing artificial 2-result limit, dynamic distance threshold).&lt;/li&gt;
  7541. &lt;li&gt;Next: Following up with genAI about models being unusable in permanent Private Browsing mode.&lt;/li&gt;
  7542. &lt;/ul&gt;
  7543. &lt;/li&gt;
  7544. &lt;li&gt;Multi-Context Address Bar (Dao)
  7545. &lt;ul&gt;
  7546. &lt;li&gt;Met up to discuss requirements for the search bar work.&lt;/li&gt;
  7547. &lt;li&gt;Decided to put off Trending Search Suggestions and Utilities for new search bar implementation for now.&lt;/li&gt;
  7548. &lt;li&gt;Nive is looking into bringing the unified search button to the search bar to ditch one-off buttons.&lt;/li&gt;
  7549. &lt;li&gt;Breaking down initial work while waiting for the unified search button vs. one-off button decision.&lt;/li&gt;
  7550. &lt;/ul&gt;
  7551. &lt;/li&gt;
  7552. &lt;li&gt;Custom Search Engines
  7553. &lt;ul&gt;
  7554. &lt;li&gt;A small patch is in review to let users add search engines from post forms with `role=search` (Moritz).&lt;/li&gt;
  7555. &lt;li&gt;Favicons weren’t showing up right away after adding a search engine via the toolbar (Moritz).&lt;/li&gt;
  7556. &lt;li&gt;If a search engine added by contextual search is removed, it can’t be re-added manually – a fix for this is in review (Moritz).&lt;/li&gt;
  7557. &lt;/ul&gt;
  7558. &lt;/li&gt;
  7559. &lt;/ul&gt;
  7560. &lt;ul&gt;
  7561. &lt;li&gt;General Search &amp;amp; Telemetry
  7562. &lt;ul&gt;
  7563. &lt;li&gt;Digging into our Bing stats to see if they match up with what Bing sees (Standard8).&lt;/li&gt;
  7564. &lt;li&gt;Implemented SERP telemetry for the DuckDuckGo Shopping tab, just dealing with a test hiccup (Stephanie).&lt;/li&gt;
  7565. &lt;li&gt;Started on Qwant’s shopping tab telemetry; it’s pretty similar to DDG, so hopefully a lot of the code can be reused (Stephanie).&lt;/li&gt;
  7566. &lt;li&gt;Confirmed and closed a bug about Glean impression events for the Google shopping tab not reporting correctly (Stephanie).&lt;/li&gt;
  7567. &lt;li&gt;Got a proof-of-concept patch for observing network requests for SERP telemetry (James).&lt;/li&gt;
  7568. &lt;li&gt;Found out that ad clicks for Ecosia and Google ad services weren’t being reported right, and issued a fix (James).&lt;/li&gt;
  7569. &lt;li&gt;Created a proof-of-concept patch to cache whether a user has used a search engine locally, instead of making new preferences for each one (James).&lt;/li&gt;
  7570. &lt;/ul&gt;
  7571. &lt;/li&gt;
  7572. &lt;/ul&gt;
  7573. &lt;ul&gt;
  7574. &lt;li&gt;General Address Bar
  7575. &lt;ul&gt;
  7576. &lt;li&gt;Fixed more TypeScript issues in the address bar code (Standard8).&lt;/li&gt;
  7577. &lt;li&gt;Sometimes the search term sticks in the URL bar; investigated but couldn’t reproduce, so added a check and filed a follow-up for a refactor (James).&lt;/li&gt;
  7578. &lt;li&gt;A bug fix for the URL bar falling back to the user-typed string instead of a suggestion when entering search mode landed (Yazan).&lt;/li&gt;
  7579. &lt;li&gt;Getting ready to land a bug that removes the URL bar placeholder when `keyword.enabled` is false (Moritz).&lt;/li&gt;
  7580. &lt;li&gt;Working on making sure the Unified Search Button UI makes sense when `keyword.enabled` is false (Dharma).&lt;/li&gt;
  7581. &lt;li&gt;Ready to land a test for ctrl/accel/shift-clicking results in the URL bar (Dharma).&lt;/li&gt;
  7582. &lt;li&gt;Still waiting for UX feedback on a bug to make command-clicking URL bar results open in a background tab on macOS (Dharma).&lt;/li&gt;
  7583. &lt;/ul&gt;
  7584. &lt;/li&gt;
  7585. &lt;/ul&gt;</description>

  7590. <title>Firefox Add-on Reviews: Translate the web easily with a browser extension</title>
  7591. <guid isPermaLink="true">https://addons.mozilla.org/blog/translate-the-web-easily-with-a-browser-extension/</guid>
  7592. <link>https://addons.mozilla.org/blog/translate-the-web-easily-with-a-browser-extension/</link>
  7593. <description>&lt;p&gt;Do you do a lot of language translating on the web? Are you constantly copying text from one browser tab and navigating to another to paste it? Maybe you like to compare translations from different services like Google Translate or Bing Translate? Need easy access to text-to-speech features? &lt;/p&gt;
  7594.  
  7595.  
  7596.  
  7597. &lt;p&gt;Online translation services provide a hugely valuable function, but for those of us who do a lot of translating on the web, the process is time-consuming and cumbersome. With the right browser extension, however, web translations become a whole lot easier and faster. Here are some fantastic translation extensions for folks with differing needs…&lt;/p&gt;
  7598.  
  7599.  
  7600.  
  7601. &lt;h3&gt;&lt;em&gt;&lt;span class=&quot;has-inline-color has-light-green-cyan-color&quot;&gt;I just want a simple, efficient way to translate. I don’t need fancy features.&lt;/span&gt;&lt;/em&gt;&lt;/h3&gt;
  7602.  
  7603.  
  7604.  
  7605. &lt;h4&gt;Simple Translate&lt;/h4&gt;
  7606.  
  7607.  
  7608.  
  7609. &lt;p&gt;It doesn’t get much simpler than this. Highlight the text you want to translate and click the extension’s toolbar icon to activate a streamlined pop-up. Your highlighted text automatically appears in the pop-up’s translation field and a drop-down menu lets you easily select your target language. &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/simple-translate/&quot; rel=&quot;noreferrer noopener&quot;&gt;Simple Translate&lt;/a&gt; also features a handy “Translate this page” button should you want that. &lt;/p&gt;
  7610.  
  7611.  
  7612.  
  7613. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7614.  
  7615.  
  7616.  
  7617. &lt;h4&gt;Translate Web Pages&lt;/h4&gt;
  7618.  
  7619.  
  7620.  
  7621. &lt;p&gt;Maybe you just need to translate full web pages, like reading news articles in other languages, how-to guides, or job related sites. If so, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/traduzir-paginas-web/&quot; rel=&quot;noreferrer noopener&quot;&gt;Translate Web Pages&lt;/a&gt; could be the ideal solution for you with its sharp focus on full-page utility. &lt;/p&gt;
  7622.  
  7623.  
  7624.  
  7625. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7626.  
  7627.  
  7628.  
  7629. &lt;p&gt;However the extension also benefits from a few intriguing additional features, like the ability to select up to three top languages you most commonly translate into (each one easily accessible with a single click in the pop-up menu), designate specific sites to always translate for you upon arrival, and your choice of three translation engines: Google, Yandex, and DeepL. &lt;/p&gt;
  7630.  
  7631.  
  7632.  
  7633. &lt;h4&gt;S3.Translator&lt;/h4&gt;
  7634.  
  7635.  
  7636.  
  7637. &lt;p&gt;Supporting 100+ languages, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/s3_translator/&quot; rel=&quot;noreferrer noopener&quot;&gt;S3.Translator&lt;/a&gt; serves up a full feature set of language tools, like the ability to translate full or select portions of a page, text-to-speech translation, YouTube subtitle translations, and more.&lt;/p&gt;
  7638.  
  7639.  
  7640.  
  7641. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7642.  
  7643.  
  7644.  
  7645. &lt;p&gt;There’s even a nifty Learning Language mode, which allows you to turn any text into the language you’re studying. Toggle between languages so you can conveniently learn as you naturally browse the web.&lt;/p&gt;
  7646.  
  7647.  
  7648.  
  7649. &lt;h4&gt;To Google Translate&lt;/h4&gt;
  7650.  
  7651.  
  7652.  
  7653. &lt;p&gt;Very popular, very simple translation extension that exclusively uses Google’s translation services, including text-to-speech. &lt;/p&gt;
  7654.  
  7655.  
  7656.  
  7657. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7658.  
  7659.  
  7660.  
  7661. &lt;p&gt;Simply highlight any text on a web page and right-click to pull up a &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/to-google-translate/&quot; rel=&quot;noreferrer noopener&quot;&gt;To Google Translate&lt;/a&gt; context menu that allows three actions: 1) translate into your preferred language; 2) listen to audio of the text; 3) Translate the entire page&lt;/p&gt;
  7662.  
  7663.  
  7664.  
  7665. &lt;figure class=&quot;wp-block-image&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-142&quot; height=&quot;619&quot; src=&quot;https://mozamo.wpengine.com/wp-content/uploads/2021/06/blogTGT-1024x619.png&quot; width=&quot;1024&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;Right-click any highlighted text to activate To Google Translate.&amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  7666.  
  7667.  
  7668.  
  7669. &lt;h3&gt;&lt;em&gt;I do a ton of translating. I need power features to save me time and trouble.&lt;/em&gt;&lt;/h3&gt;
  7670.  
  7671.  
  7672.  
  7673. &lt;h4&gt;ImTranslator&lt;/h4&gt;
  7674.  
  7675.  
  7676.  
  7677. &lt;p&gt;Striking a balance between out-of-the-box ease and deep customization potential, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/imtranslator/&quot; rel=&quot;noreferrer noopener&quot;&gt;ImTranslator&lt;/a&gt; leverages three top translation engines (Google, Bing, Translator) to cover 100+ languages; the extension itself is even available in nearly two-dozen languages. &lt;/p&gt;
  7678.  
  7679.  
  7680.  
  7681. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7682.  
  7683.  
  7684.  
  7685. &lt;p&gt;Other strong features include text-to-speech, dictionary and spell check in eight languages, hotkey customization, and a huge array of ways to tweak the look of ImTranslator’s interface—from light and dark themes to font size and more. &lt;/p&gt;
  7686.  
  7687.  
  7688.  
  7689. &lt;h4&gt;Mate Translate&lt;/h4&gt;
  7690.  
  7691.  
  7692.  
  7693. &lt;p&gt;A slick, intuitive extension that performs all the basic translation functions very well, but it’s &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/instant-translate/&quot; rel=&quot;noreferrer noopener&quot;&gt;Mate Translate&lt;/a&gt;’s paid tier that unlocks some unique features, such as Sync (saved translations can appear across devices and browsers, including iPhones and Mac). &lt;/p&gt;
  7694.  
  7695.  
  7696.  
  7697. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7698.  
  7699.  
  7700.  
  7701. &lt;p&gt;There’s also a neat Phrasebook feature, which lets you build custom word and phrase lists so you can return to common translations you frequently need. It works offline, too, so it’s ideal for travellers who need quick reference to common foreign phrases. &lt;/p&gt;
  7702.  
  7703.  
  7704.  
  7705. &lt;p&gt;These are some of our favorites, but there are plenty &lt;a href=&quot;https://addons.mozilla.org/firefox/search/?q=translate&quot; rel=&quot;noreferrer noopener&quot;&gt;more translation extensions to explore&lt;/a&gt; on &lt;em&gt;addons.mozilla.org&lt;/em&gt;.&lt;/p&gt;</description>

  7710. <title>Firefox Add-on Reviews: Top anti-tracking extensions</title>
  7711. <guid isPermaLink="true">https://addons.mozilla.org/blog/top-anti-tracking-extensions/</guid>
  7712. <link>https://addons.mozilla.org/blog/top-anti-tracking-extensions/</link>
  7713. <description>&lt;p&gt;The truth of modern tracking is that it happens in so many different and complex ways it’s practically impossible to ensure absolute tracking protection. But that doesn’t mean we’re powerless against personal data harvesters attempting to trace our every online move. There are a bunch of Firefox browser extensions that can give you tremendous anti-tracking advantages… &lt;/p&gt;
  7714.  
  7715.  
  7716.  
  7717. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;Privacy Badger&lt;/strong&gt;&lt;/h3&gt;
  7718.  
  7719.  
  7720.  
  7721. &lt;p&gt;Sophisticated and effective anti-tracker that doesn’t require any setup whatsoever. Simply install &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/privacy-badger17/&quot; rel=&quot;noreferrer noopener&quot;&gt;Privacy Badger&lt;/a&gt; and right away it begins the work of finding the most hidden types of tackers on the web. &lt;/p&gt;
  7722.  
  7723.  
  7724.  
  7725. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7726.  
  7727.  
  7728.  
  7729. &lt;p&gt;Produced by leading edge digital rights organization &lt;a href=&quot;https://www.eff.org/&quot; rel=&quot;noreferrer noopener&quot;&gt;Electronic Frontier Foundation&lt;/a&gt;, Privacy Badger sends &lt;a href=&quot;https://prod.outgoing.prod.webservices.mozgcp.net/v1/f5433e6e384e33b2921d74ea02a8ada23fd2a7a9e1dd4c0382bc0cbb9dbc0864/https%3A//globalprivacycontrol.org/&quot; rel=&quot;noreferrer noopener&quot;&gt;Global Privacy Control&lt;/a&gt; and &lt;a href=&quot;https://prod.outgoing.prod.webservices.mozgcp.net/v1/9945620a688bfc1f32e4ecd44d4e6d6006bfb763b04c194293b87fa00acc9446/https%3A//www.eff.org/issues/do-not-track&quot; rel=&quot;noreferrer noopener&quot;&gt;Do Not Track&lt;/a&gt; opt-out signals to third parties trying to monitor your moves around the web. If those signals are ignored, Privacy Badger blocks them. This fantastic privacy extension also removes outgoing link tracking on Facebook and Google.&lt;/p&gt;
  7730.  
  7731.  
  7732.  
  7733. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Decentraleyes&lt;/h3&gt;
  7734.  
  7735.  
  7736.  
  7737. &lt;p&gt;Another strong privacy protector that works well right out of the box, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/decentraleyes/&quot; rel=&quot;noreferrer noopener&quot;&gt;Decentraleyes&lt;/a&gt; effectively halts web page tracking requests from reaching third party content delivery networks (i.e. ad tech). &lt;/p&gt;
  7738.  
  7739.  
  7740.  
  7741. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7742.  
  7743.  
  7744.  
  7745. &lt;p&gt;A common issue with other extensions that try to block tracking requests is they also sometimes break the page itself, which is obviously not a great outcome. Decentraleyes solves this unfortunate side effect by injecting inert local files into the request, which protects your privacy (by distributing generic data instead of your personal info) while ensuring web pages don’t break in the process. Decentraleyes is also designed to work well with other types of content blockers like &lt;a href=&quot;https://addons.mozilla.org/blog/whats-the-best-ad-blocker-for-you/&quot; rel=&quot;noreferrer noopener&quot;&gt;ad blockers&lt;/a&gt;.  &lt;/p&gt;
  7746.  
  7747.  
  7748.  
  7749. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;ClearURLs&lt;/strong&gt;&lt;/h3&gt;
  7750.  
  7751.  
  7752.  
  7753. &lt;p&gt;Ever noticed those long tracking codes that often get tagged to the end of your search result links or URLs on product pages from shopping sites? All that added guck to the URL is designed to track how you interact with the link. &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/clearurls/&quot; rel=&quot;noreferrer noopener&quot;&gt;ClearURLs&lt;/a&gt; automatically removes the tracking clutter from links—giving you cleaner links and more privacy. &lt;/p&gt;
  7754.  
  7755.  
  7756.  
  7757. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7758.  
  7759.  
  7760.  
  7761. &lt;p&gt;Other key features include…&lt;/p&gt;
  7762.  
  7763.  
  7764.  
  7765. &lt;ul class=&quot;wp-block-list&quot;&gt;
  7766. &lt;li&gt;Clean up multiple URLs at once&lt;/li&gt;
  7767.  
  7768.  
  7769.  
  7770. &lt;li&gt;Block hyperlink auditing (i.e. “ping tracking”; a method websites use to track clicks)&lt;/li&gt;
  7771.  
  7772.  
  7773.  
  7774. &lt;li&gt;Block ETag tracking (i.e. “entity tags”; a tracking alternative to cookies)&lt;/li&gt;
  7775.  
  7776.  
  7777.  
  7778. &lt;li&gt;Prevent Google and Yandex from rewriting search results to add tracking elements&lt;/li&gt;
  7779.  
  7780.  
  7781.  
  7782. &lt;li&gt;Block some common ad domains (optional)&lt;/li&gt;
  7783. &lt;/ul&gt;
  7784.  
  7785.  
  7786.  
  7787. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Consent-O-Matic&lt;/h3&gt;
  7788.  
  7789.  
  7790.  
  7791. &lt;p&gt;Tired of dealing with annoying — and often intentionally misleading — cookie pop-ups? &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/addon/consent-o-matic/&quot;&gt;Consent-O-Matic&lt;/a&gt; will automatically deny tracking permissions for you.&lt;/p&gt;
  7792.  
  7793.  
  7794.  
  7795. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7796.  
  7797.  
  7798.  
  7799. &lt;p&gt;The extension is designed and maintained by a group of privacy researchers at Aarhus University in Denmark who grew sick of seeing so many sneaky consent pop-ups use language that was clearly intended to trick users into agreeing to be tracked. &lt;/p&gt;
  7800.  
  7801.  
  7802.  
  7803. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Port Authority&lt;/h3&gt;
  7804.  
  7805.  
  7806.  
  7807. &lt;p&gt;This extension addresses a distinct yet little understood privacy problem of port scanning (i.e. when websites scan their users’ internet-facing devices to learn what apps and services are listening on the network). &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/addon/port-authority/&quot; rel=&quot;noreferrer noopener&quot;&gt;Port Authority&lt;/a&gt; effectively halts inappropriate port scan requests to your private network.&lt;/p&gt;
  7808.  
  7809.  
  7810.  
  7811. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7812.  
  7813.  
  7814.  
  7815. &lt;p&gt;For a deeper dive into Port Authority and how it protects user privacy, please see our &lt;a href=&quot;https://blog.mozilla.org/addons/2024/05/07/developer-spotlight-port-authority/&quot; rel=&quot;noreferrer noopener&quot;&gt;interview with its developer&lt;/a&gt;. Learn more about the extension’s origin and how it addresses a distinct need in the realm of digital privacy protection.&lt;/p&gt;

  7819. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;Cookie AutoDelete&lt;/strong&gt;&lt;/h3&gt;
  7820.  
  7821.  
  7822.  
  7823. &lt;p&gt;Take control of your cookie trail with &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/cookie-autodelete/&quot; rel=&quot;noreferrer noopener&quot;&gt;Cookie AutoDelete&lt;/a&gt;. Set it so cookies are automatically deleted every time you close a tab, or create safelists for select sites you want to preserve cookies. &lt;/p&gt;
  7824.  
  7825.  
  7826.  
  7827. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7828.  
  7829.  
  7830.  
  7831. &lt;p&gt;After installation, you must enable “Auto-clean” for the extension to automatically wipe away cookies. This is so you first have an opportunity to create a custom safelist, should you choose, before accidentally clearing away cookies you might want to keep. &lt;/p&gt;
  7832.  
  7833.  
  7834.  
  7835. &lt;p&gt;There’s not much you have to do once you’ve got your safelist set, but clicking the extension’s toolbar button opens a pop-up menu with a few convenient options, like the ability to wipe away cookies from open tabs or clear cookies for just a particular domain.&lt;/p&gt;
  7836.  
  7837.  
  7838.  
  7839. &lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-255&quot; height=&quot;642&quot; src=&quot;https://mozamo.wpengine.com/wp-content/uploads/2021/09/blog_cad-1024x642.jpg&quot; width=&quot;1024&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;Cookie AutoDelete’s pop-up menu gives you accessible cookie control wherever you go online. &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  7840.  
  7841.  
  7842.  
  7843. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Firefox Multi-Account Containers&lt;/h3&gt;
  7844.  
  7845.  
  7846.  
  7847. &lt;p&gt;Do you need to be simultaneously logged in to multiple accounts on the same platform, say for instance juggling various accounts on Google, Twitter, or Reddit? &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/multi-account-containers/&quot; rel=&quot;noreferrer noopener&quot;&gt;Multi-Account Containers&lt;/a&gt; can make your life a whole lot easier by helping you keep your many accounts “contained” in separate tabs so you can easily navigate between them without a need to constantly log in/out. &lt;/p&gt;
  7848.  
  7849.  
  7850.  
  7851. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7852.  
  7853.  
  7854.  
  7855. &lt;p&gt;By isolating your identities through containers, your browsing activity from one container isn’t correlated to another—making it far more difficult for these platforms to track and profile your holistic browsing behavior. &lt;/p&gt;
  7856.  
  7857.  
  7858.  
  7859. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Facebook Container&lt;/h3&gt;
  7860.  
  7861.  
  7862.  
  7863. &lt;p&gt;Does it come as a surprise that Facebook tries to track your online behavior beyond the confines of just Facebook? If so, I’m sorry to be the bearer of bad news. &lt;a href=&quot;https://blog.mozilla.org/products/firefox/cross-site-tracking-lets-unpack-that/&quot; rel=&quot;noreferrer noopener&quot;&gt;Facebook definitely tries to track you outside of Facebook&lt;/a&gt;. But with &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/facebook-container/&quot; rel=&quot;noreferrer noopener&quot;&gt;Facebook Container&lt;/a&gt; you can put a privacy barrier between the social media giant and your online life outside of it. &lt;/p&gt;
  7864.  
  7865.  
  7866.  
  7867. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7868.  
  7869.  
  7870.  
  7871. &lt;p&gt;Facebook primarily investigates your interests outside of Facebook through their various widgets you find embedded ubiquitously about the web (e.g. “Like” buttons or Facebook comments on articles, social share features, etc.) &lt;/p&gt;
  7872.  
  7873.  
  7874.  
  7875. &lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-257&quot; height=&quot;713&quot; src=&quot;https://mozamo.wpengine.com/wp-content/uploads/2021/09/blog_fbc2-1024x713.jpg&quot; width=&quot;1024&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;Social widgets like these give Facebook and other platforms a sneaky means of tracking your interests around the web.&amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  7876.  
  7877.  
  7878.  
  7879. &lt;p&gt;The privacy trade we make for the convenience of not needing to sign in to Facebook each time we visit the site (because it recognizes your browser as yours) is we give Facebook a potent way to track our moves around the web, since it can tell when you visit any web page embedded with its widgets. &lt;/p&gt;
  7880.  
  7881.  
  7882.  
  7883. &lt;p&gt;Facebook Container basically allows you the best of both worlds—you can preserve the convenience of not needing to sign in/out of Facebook, while placing a “container” around your Facebook profile so the company can’t follow you around the web anymore.&lt;/p&gt;
  7884.  
  7885.  
  7886.  
  7887. &lt;h3 class=&quot;wp-block-heading&quot;&gt;CanvasBlocker&lt;/h3&gt;
  7888.  
  7889.  
  7890.  
  7891. &lt;p&gt;Stop websites from using JavaScript APIs to “fingerprint” you when you visit. &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/canvasblocker/&quot; rel=&quot;noreferrer noopener&quot;&gt;CanvasBlocker&lt;/a&gt; prevents a uniquely common way websites try to track your web moves. &lt;/p&gt;
  7892.  
  7893.  
  7894.  
  7895. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7896.  
  7897.  
  7898.  
  7899. &lt;p&gt;Best suited for more technical users, CanvasBlocker lets you customize which API’s should be protected from fingerprinting — on some or all websites. The extension can even be configured to alter your API identity to further obfuscate your online identity. &lt;/p&gt;
  7900.  
  7901.  
  7902.  
  7903. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Disconnect&lt;/h3&gt;
  7904.  
  7905.  
  7906.  
  7907. &lt;p&gt;Strong privacy tool that fares well against hidden trackers used by some of the biggest data trackers in the game like Google, Facebook, Twitter and others, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/disconnect/&quot; rel=&quot;noreferrer noopener&quot;&gt;Disconnect&lt;/a&gt; also provides the benefit of significantly speeding up page loads simply by virtue of blocking all the unwanted tracking traffic. &lt;/p&gt;
  7908.  
  7909.  
  7910.  
  7911. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7912.  
  7913.  
  7914.  
  7915. &lt;p&gt;Once installed, you’ll find a Disconnect button in your browser toolbar. Click it when visiting any website to see the number of trackers blocked (and where they’re from). You can also opt to unblock anything you feel you might need in your browsing experience. &lt;/p&gt;
  7916.  
  7917.  
  7918.  
  7919. &lt;p&gt;We hope one of these anti-tracker extensions provides you with a strong new layer of security. Feel free to explore more &lt;a href=&quot;https://addons.mozilla.org/firefox/collections/4757633/privacy-matters/&quot; rel=&quot;noreferrer noopener&quot;&gt;powerful privacy extensions&lt;/a&gt; on &lt;em&gt;addons.mozilla.org&lt;/em&gt;. &lt;/p&gt;</description>

  7924. <title>Firefox Add-on Reviews: Reddit revolutionized—use a browser extension to enhance your favorite forum</title>
  7925. <guid isPermaLink="true">https://addons.mozilla.org/blog/reddit-revolutionized-use-a-browser-extension-to-enhance-your-favorite-forum/</guid>
  7926. <link>https://addons.mozilla.org/blog/reddit-revolutionized-use-a-browser-extension-to-enhance-your-favorite-forum/</link>
  7927. <description>&lt;p&gt;Reddit is awash with great conversation (well, &lt;a href=&quot;https://www.reddit.com/r/notinteresting/&quot; rel=&quot;noreferrer noopener&quot;&gt;not all the time)&lt;/a&gt;. There’s a Reddit message board for just about everybody—&lt;a href=&quot;https://www.reddit.com/subreddits/leaderboard/sports/&quot; rel=&quot;noreferrer noopener&quot;&gt;sports fans&lt;/a&gt;, &lt;a href=&quot;https://www.reddit.com/subreddits/leaderboard/gaming/&quot; rel=&quot;noreferrer noopener&quot;&gt;gamers&lt;/a&gt;, &lt;a href=&quot;https://www.reddit.com/r/FoodHaikus/&quot; rel=&quot;noreferrer noopener&quot;&gt;poets inspired by food&lt;/a&gt;, &lt;a href=&quot;https://www.reddit.com/r/birdswitharms/&quot; rel=&quot;noreferrer noopener&quot;&gt;people who like arms on birds&lt;/a&gt;—you get the idea. &lt;/p&gt;
  7928.  
  7929.  
  7930.  
  7931. &lt;p&gt;If you spend time on Reddit, there are ways to greatly augment your experience with a browser extension… &lt;/p&gt;
  7932.  
  7933.  
  7934.  
  7935. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Reddit Enhancement Suite&lt;/h3&gt;
  7936.  
  7937.  
  7938.  
  7939. &lt;p&gt;Used by more the two million Redditors across various browsers, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/reddit-enhancement-suite/&quot; rel=&quot;noreferrer noopener&quot;&gt;Reddit Enhancement Suite&lt;/a&gt; is optimized to work with the beloved “old Reddit” (the website underwent a major redesign in 2018; you can still access the prior design by visiting &lt;em&gt;old.reddit.com&lt;/em&gt;). &lt;/p&gt;
  7940.  
  7941.  
  7942.  
  7943. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7944.  
  7945.  
  7946.  
  7947. &lt;p&gt;Key features: &lt;/p&gt;
  7948.  
  7949.  
  7950.  
  7951. &lt;ul class=&quot;wp-block-list&quot;&gt;
  7952. &lt;li&gt;&lt;strong&gt;Subreddit manager&lt;/strong&gt;. Customize the top nav bar with your own subreddit shortcuts. &lt;/li&gt;
  7953.  
  7954.  
  7955.  
  7956. &lt;li&gt;&lt;strong&gt;Account switcher&lt;/strong&gt;. Easily manage multiple Reddit accounts with a couple quick clicks. &lt;/li&gt;
  7957.  
  7958.  
  7959.  
  7960. &lt;li&gt;&lt;strong&gt;Show “parent” comment on hover&lt;/strong&gt;. When you mouse over a comment, its “parent” comment displays. &lt;/li&gt;
  7961.  
  7962.  
  7963.  
  7964. &lt;li&gt;&lt;strong&gt;Dashboard&lt;/strong&gt;. Fully customizable dashboard showcases content from subreddits, your message inbox, and more. &lt;/li&gt;
  7965.  
  7966.  
  7967.  
  7968. &lt;li&gt;&lt;strong&gt;Tag&lt;/strong&gt; specific users and subreddits so their activity appears more prominently&lt;/li&gt;
  7969.  
  7970.  
  7971.  
  7972. &lt;li&gt;&lt;strong&gt;Custom filters&lt;/strong&gt;. Select words, subreddits, or even certain users that you want filtered out of your Reddit experience. &lt;/li&gt;
  7973.  
  7974.  
  7975.  
  7976. &lt;li&gt;&lt;strong&gt;New comment count&lt;/strong&gt;. See the number of new comments on a thread since your last visit. &lt;/li&gt;
  7977.  
  7978.  
  7979.  
  7980. &lt;li&gt;&lt;strong&gt;Never Ending Reddit&lt;/strong&gt;. Just keep scrolling down the page; new content will continue loading (until you reach the end of the internet?). &lt;/li&gt;
  7981. &lt;/ul&gt;
  7982.  
  7983.  
  7984.  
  7985. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Old Reddit Redirect&lt;/h3&gt;
  7986.  
  7987.  
  7988.  
  7989. &lt;p&gt;Speaking of the former design, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/old-reddit-redirect/&quot; rel=&quot;noreferrer noopener&quot;&gt;Old Reddit Redirect&lt;/a&gt; provides a straightforward function. It simply ensures that every Reddit page you visit will redirect to the &lt;em&gt;old.reddit.com&lt;/em&gt; domain. &lt;/p&gt;
  7990.  
  7991.  
  7992.  
  7993. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  7994.  
  7995.  
  7996.  
  7997. &lt;p&gt;Sure, if you have a Reddit account the site gives you the option of using the old design, but with the browser extension you’ll get the old site regardless of being logged in or not. It’s also great for when you click Reddit links shared from the new domain. &lt;/p&gt;
  7998.  
  7999.  
  8000.  
  8001. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;Reddit Comment Collapser&lt;/strong&gt;&lt;/h3&gt;
  8002.  
  8003.  
  8004.  
  8005. &lt;p&gt;No more getting lost in confusing comment threads for users of &lt;strong&gt;old.reddt.com&lt;/strong&gt;. &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/addon/reddit_comment_collapser/&quot; rel=&quot;noreferrer noopener&quot;&gt;Reddit Comment Collapser&lt;/a&gt; cleans up your commentary view with a simple mouse click.&lt;/p&gt;
  8006.  
  8007.  
  8008.  
  8009. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8010.  
  8011.  
  8012.  
  8013. &lt;p&gt;Compatible with &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/addon/reddit-enhancement-suite/&quot; rel=&quot;noreferrer noopener&quot;&gt;Reddit Enhancement Suite&lt;/a&gt; and &lt;a href=&quot;https://addons.mozilla.org/en-US/firefox/addon/old-reddit-redirect/&quot; rel=&quot;noreferrer noopener&quot;&gt;Old Reddit Redirect&lt;/a&gt;, this single-use extension is beloved by many seeking a minimalist view of the classic Reddit.&lt;/p&gt;
  8014.  
  8015.  
  8016.  
  8017. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Reddit on YouTube&lt;/h3&gt;
  8018.  
  8019.  
  8020.  
  8021. &lt;p&gt;Bring Reddit with you to YouTube. Whenever you’re on a YouTube page, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/reddit-on-youtube/&quot; rel=&quot;noreferrer noopener&quot;&gt;Reddit on YouTube&lt;/a&gt; searches for Reddit posts that link to the video and embeds those comments into the YouTube comment area. &lt;/p&gt;
  8022.  
  8023.  
  8024.  
  8025. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8026.  
  8027.  
  8028.  
  8029. &lt;p&gt;You can easily toggle between Reddit and YouTube comments and select either one to be your default preference. &lt;/p&gt;
  8030.  
  8031.  
  8032.  
  8033. &lt;figure class=&quot;wp-block-image size-large&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-178&quot; height=&quot;716&quot; src=&quot;https://mozamo.wpengine.com/wp-content/uploads/2021/07/blog_reddit_comment-1-1024x716.png&quot; width=&quot;1024&quot; /&gt;&amp;lt;figcaption class=&quot;wp-element-caption&quot;&amp;gt;If there are multiple Reddit threads about the video you’re watching, the extension will display them in tab form in the YouTube comment section.  &amp;lt;/figcaption&amp;gt;&lt;/figure&gt;
  8034.  
  8035.  
  8036.  
  8037. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Reddit Ad Remover&lt;/h3&gt;
  8038.  
  8039.  
  8040.  
  8041. &lt;p&gt;Sick of seeing so many “Promoted” posts and paid advertisements in the feed and sidebar? &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/reddit-ad-remover/&quot; rel=&quot;noreferrer noopener&quot;&gt;Reddit Ad Remover&lt;/a&gt; silences the noise. &lt;/p&gt;
  8042.  
  8043.  
  8044.  
  8045. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8046.  
  8047.  
  8048.  
  8049. &lt;p&gt;The extension even blocks auto-play video ads, which is great for people who don’t appreciate sudden bursts of commercial sound. Hey, somebody should &lt;a href=&quot;https://www.reddit.com/r/badads/&quot; rel=&quot;noreferrer noopener&quot;&gt;create a subreddit about this&lt;/a&gt;! &lt;/p&gt;
  8050.  
  8051.  
  8052.  
  8053. &lt;p&gt;Happy redditing, folks. Feel free to explore more &lt;a href=&quot;https://addons.mozilla.org/firefox/extensions/category/feeds-news-blogging/&quot; rel=&quot;noreferrer noopener&quot;&gt;news and media extensions&lt;/a&gt; on &lt;em&gt;addons.mozilla.org&lt;/em&gt;.&lt;/p&gt;</description>

  8058. <title>Firefox Add-on Reviews: Tweak Twitch—BetterTTV and other  extensions for Twitch customization</title>
  8059. <guid isPermaLink="true">https://addons.mozilla.org/blog/tweak-twitch-betterttv-and-other-extensions-for-twitch-customization/</guid>
  8060. <link>https://addons.mozilla.org/blog/tweak-twitch-betterttv-and-other-extensions-for-twitch-customization/</link>
  8061. <description>&lt;p&gt;Customize chat, optimize your video player, auto-collect channel points, and much much more. Explore some of the ways you can radically transform your Twitch experience with a browser extension… &lt;/p&gt;
  8062.  
  8063.  
  8064.  
  8065. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;BetterTTV&lt;/strong&gt;&lt;/h3&gt;
  8066.  
  8067.  
  8068.  
  8069. &lt;p&gt;One of the most feature rich and popular Twitch extensions out there, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/betterttv/&quot; rel=&quot;noreferrer noopener&quot;&gt;BetterTTV&lt;/a&gt; has everything from fun new emoticons to advanced content filtering. &lt;/p&gt;
  8070.  
  8071.  
  8072.  
  8073. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8074.  
  8075.  
  8076.  
  8077. &lt;p&gt;Key features:&lt;/p&gt;
  8078.  
  8079.  
  8080.  
  8081. &lt;ul class=&quot;wp-block-list&quot;&gt;
  8082. &lt;li&gt;Auto-collect channel points&lt;/li&gt;
  8083.  
  8084.  
  8085.  
  8086. &lt;li&gt;Easier-to-read chat interface&lt;/li&gt;
  8087.  
  8088.  
  8089.  
  8090. &lt;li&gt;Select usernames, words, or specific phrases you want highlighted throughout Twitch; or blacklist any of those elements you want filtered out&lt;/li&gt;
  8091.  
  8092.  
  8093.  
  8094. &lt;li&gt;New emoticons to use globally or custom per channel&lt;/li&gt;
  8095.  
  8096.  
  8097.  
  8098. &lt;li&gt;See deleted messages&lt;/li&gt;
  8099.  
  8100.  
  8101.  
  8102. &lt;li&gt;Anonymous Chat—join a channel without notice&lt;/li&gt;
  8103. &lt;/ul&gt;
  8104.  
  8105.  
  8106.  
  8107. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;Alternative Player for Twitch.tv&lt;/strong&gt;&lt;/h3&gt;
  8108.  
  8109.  
  8110.  
  8111. &lt;p&gt;While this extension’s focus is on video player customization, &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/twitch_5/&quot; rel=&quot;noreferrer noopener&quot;&gt;Alternate Player for Twitch.tv&lt;/a&gt; packs a bunch of other great features unrelated to video streaming. &lt;/p&gt;
  8112.  
  8113.  
  8114.  
  8115. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8116.  
  8117.  
  8118.  
  8119. &lt;p&gt;Let’s start with the video player. Some of its best tweaks include:&lt;/p&gt;
  8120.  
  8121.  
  8122.  
  8123. &lt;ul class=&quot;wp-block-list&quot;&gt;
  8124. &lt;li&gt;Ad blocking! Wipe away all of those suuuuper looooong pre-rolls&lt;/li&gt;
  8125.  
  8126.  
  8127.  
  8128. &lt;li&gt;Choose a new color for the player &lt;/li&gt;
  8129.  
  8130.  
  8131.  
  8132. &lt;li&gt;Instant Replay is a wow feature—go back and watch up to a minute of material that just streamed (includes ability to speed up/slow down replay) &lt;/li&gt;
  8133. &lt;/ul&gt;
  8134.  
  8135.  
  8136.  
  8137. &lt;p&gt;Alternate Player for Twitch.tv also appears to run live streams at even smoother rates than Twitch’s default player. You can further optimize your stream by adjusting the extension’s bandwidth settings to better suit your internet speed. Audio Only mode is really great for saving bandwidth if you’re just tuning in for music or discussion. &lt;/p&gt;
  8138.  
  8139.  
  8140.  
  8141. &lt;p&gt;Our favorite feature is the ability to customize the size and location of the chat interface while in full-screen mode. Make the chat small and tuck it away in a corner or expand it to consume most of the screen; or remove chat altogether if the side conversation is a mood killer.&lt;/p&gt;
  8142.  
  8143.  
  8144.  
  8145. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Previews (for TTV &amp;amp; YT)&lt;/h3&gt;
  8146.  
  8147.  
  8148.  
  8149. &lt;p&gt;This is the best way to channel surf. Just hover over a stream icon in the sidebar and &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/previews-for-ttv/&quot; rel=&quot;noreferrer noopener&quot;&gt;Previews (for TTV &amp;amp; YT)&lt;/a&gt; will display its live video in a tiny player. &lt;/p&gt;
  8150.  
  8151.  
  8152.  
  8153. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8154.  
  8155.  
  8156.  
  8157. &lt;p&gt;No more clicking away from the thing you’re watching just to check out other streams. Additional features we love include the ability to customize the video size and volume of previews, a sidebar auto-extender (to more easily view all live streams), and full-screen mode with chat. &lt;/p&gt;
  8158.  
  8159.

  8164.  
  8165. &lt;h3 class=&quot;wp-block-heading&quot;&gt;&lt;strong&gt;Unwanted Twitch&lt;/strong&gt;&lt;/h3&gt;
  8166.  
  8167.  
  8168.  
  8169. &lt;p&gt;Do you keep seeing the same channels over and over again that you’re not interested in? &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/unwanted-twitch/&quot; rel=&quot;noreferrer noopener&quot;&gt;Unwanted Twitch&lt;/a&gt; wipes them from your experience. &lt;/p&gt;
  8170.  
  8171.  
  8172.  
  8173. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8174.  
  8175.  
  8176.  
  8177. &lt;p&gt;Not only block specific channels you don’t want, but you can even hide entire categories (&lt;em&gt;I’m done with dub step!&lt;/em&gt;) or specific tags (&lt;em&gt;my #Minecraft days are behind me&lt;/em&gt;). Other niche “hide” features include the ability to block reruns and streams with certain words appearing in their title. &lt;/p&gt;
  8178.  
  8179.  
  8180.  
  8181. &lt;h3 class=&quot;wp-block-heading&quot;&gt;Twitch Chat Pronouns&lt;/h3&gt;
  8182.  
  8183.  
  8184.  
  8185. &lt;p&gt;What a neat idea. &lt;a href=&quot;https://addons.mozilla.org/firefox/addon/twitch-chat-pronouns/&quot; rel=&quot;noreferrer noopener&quot;&gt;Twitch Chat Pronouns&lt;/a&gt; lets you add gender pronouns to usernames. &lt;/p&gt;
  8186.  
  8187.  
  8188.  
  8189. &lt;div class=&quot;addon-card&quot;&gt;&lt;/div&gt;
  8190.  
  8191.  
  8192.  
  8193. &lt;p&gt;The pronouns will display next to Twitch usernames. You’ll need to enter a pronoun for yourself if you want one to appear to other extension users. &lt;/p&gt;
  8194.  
  8195.  
  8196.  
  8197. &lt;p&gt;We hope your Twitch experience has been improved with a browser extension!&lt;a href=&quot;https://addons.mozilla.org/firefox/extensions/category/games-entertainment/&quot; rel=&quot;noreferrer noopener&quot;&gt; Find more media enhancing extensions&lt;/a&gt; on &lt;em&gt;addons.mozilla.org&lt;/em&gt;.&lt;/p&gt;</description>

  8205. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/blog-banner-community-hours-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  8206. &lt;p&gt;Welcome back to another edition of the Community Office Hours! This month, we’re taking a closer look at Thunderbird 140.0 ESR “Eclipse,” our latest Extended Support Release! Sr. Manager of Desktop Engineering Toby Pilling (who so helpfully provides the &lt;a href=&quot;https://blog.thunderbird.net/tag/development-digest/&quot;&gt;Thunderbird Monthly Development Digest&lt;/a&gt;) is walking us through the latest Thunderbird. He’ll let us know what’s in, what’s out, and why you should give the new monthly Release channel a try. We’re also introducing a new member of the Thunderbird Team, Manager of Community Programs Michael Ellis. &lt;/p&gt;
  8207.  
  8208.  
  8209.  
  8210. &lt;p&gt;Michael (and the Thunderbird team!) are here to listen, collaborate, and help you succeed. You can expect to see more initiatives, experiments, and outreach from us soon, but you don’t have to wait till then to weigh in. Have thoughts or suggestions on how to improve the community? Drop a comment below to share them directly, or &lt;a href=&quot;https://connect.mozilla.org/t5/discussions/have-ideas-to-improve-the-thunderbird-community/td-p/100264&quot; rel=&quot;noreferrer noopener&quot; target=&quot;_blank&quot;&gt;visit our Connect thread&lt;/a&gt; to see what others are saying and add your own ideas there. Together, we can help shape the future of the Thunderbird community and product.&lt;/p&gt;
  8211.  
  8212.  
  8213.  
  8214. &lt;p&gt;Next month, we’ll be talking with Product Design Rebecca Taylor and Associate Designer Solange Valverde to talk about our team’s recent efforts to make Thunderbird more accessible. This not only involves seeing where we’re doing well, but finding where we’re falling short. It’s been a while since we’ve &lt;a href=&quot;https://blog.thunderbird.net/2024/01/january-2024-thunderbird-community-office-hours-how-to-join-us/&quot;&gt;talked about Accessibility here&lt;/a&gt;, and we’re excited to continue the conversation. If you have questions about Accessibility in either the desktop or Android app you’d like us to ask our guests, please leave them as a comment below!&lt;/p&gt;
  8215.  
  8216.  
  8217.  
  8218. &lt;h3&gt;July Office Hours: Thunderbird 140.0 ESR “Eclipse”&lt;/h3&gt;
  8219.  
  8220.  
  8221.  
  8222. &lt;p&gt;As Toby shows us in his introduction, the major theme of Thunderbird 140.0 ESR “Eclipse” is stability. We took lessons from last year’s ESR, when we introduced code to 128.0 that was a little harder to test than expected given when it landed. We’re also waiting on some major changes in the works, namely the refreshed Calendar UI and the database backend rewrite. This was, every feature that made it to this year’s ESR was fully baked.&lt;/p&gt;
  8223.  
  8224.  
  8225.  
  8226. &lt;h3&gt;What’s In&lt;/h3&gt;
  8227.  
  8228.  
  8229.  
  8230. &lt;p&gt;And there’s a lot of features to discuss! Toby walks through what’s new in 140.0, starting with a trio of visual improvements. Thunderbird now adapts the message window to dark mode, and provides a toggle to switch dark mode off in case of styling issues. In the new Appearance Settings, users can globally take control of their message list, toggling between Cards and Table View, Threaded and Unthreaded, and Grouped by Sort across all their accounts. This feature also allows switching Cards View between a 2 and 3 row preview, and to propagate default sorting orders to all folders. Finally, a community-powered and staff-supported feature allows users to reorder user-created folders by manually dragging and dropping them.&lt;/p&gt;
  8231.  
  8232.  
  8233.  
  8234. &lt;p&gt;140.0 ESR Also introduces the Account Hub, which we &lt;a href=&quot;https://blog.thunderbird.net/2025/04/video-the-new-account-hub/&quot;&gt;covered in a previous Office Hours&lt;/a&gt;! You’ll see this when you add a second account, and it will seamlessly walk you through setting up not only your email, but connected address books and calendars. &lt;/p&gt;
  8235.  
  8236.  
  8237.  
  8238. &lt;p&gt;To help maximize your time and minimize your clicks, Thunderbird now uses Native Notifications for Linux, Mac, and Windows. While for now you can delete messages and mark them as read directly from notifications, we have more actions up our sleeve, coming soon to the monthly Release channel!&lt;/p&gt;
  8239.  
  8240.  
  8241.  
  8242. &lt;p&gt;Finally, we close out our new features. Experimental Exchange Support, which can be enabled via preference, introduces native Exchange email support to desktop Thunderbird. Though for a fully supported experience, we encourage you to switch to the monthly Release channel, where more Exchange improvements are coming. Export for Mobile allows you to generate a QR code to import your account configurations and credentials into the Thunderbird Android app. And Horizontal Scroll for Table View allows you to scroll the message list horizontally and read complex tabular data more like a spreadsheet.&lt;/p&gt;
  8243.  
  8244.  
  8245.  
  8246. &lt;h3&gt;What’s Out&lt;/h3&gt;
  8247.  
  8248.  
  8249.  
  8250. &lt;p&gt;But for everything we put in to 140.0 ESR, we had to leave some things out. Experimental Exchange Support only includes email, not calendar or address books. We also don’t yet support Graph API. Additionally, 140.0 ESR doesn’t include a new UI for Tasks, Chat, or Settings. Account Hub won’t be enabled for first-time user experiences in ESR, though this will be coming to monthly Release, as will the new Account Hub for Address Books.&lt;/p&gt;
  8251.  
  8252.  
  8253.  
  8254. &lt;h3&gt;Try the Monthly Release Channel&lt;/h3&gt;
  8255.  
  8256.  
  8257.  
  8258. &lt;p&gt;While we’re excited and proud to introduce Thunderbird 140.0 ESR “Eclipse,” we also hope you’ll try out new monthly Release channel. Read more about it and learn how you can get new features faster &lt;a href=&quot;https://blog.thunderbird.net/2025/02/thunderbird-desktop-release-channel-default-download/&quot;&gt;in our announcement.&lt;/a&gt;&lt;/p&gt;
  8259.

  8261.  
  8262. &lt;h3&gt;Watch, Read, and Get Involved&lt;/h3&gt;
  8263.  
  8264.

  8336. <title>Niko Matsakis: You won't believe what this AI said after deleting a database (but you might relate)</title>
  8337. <guid isPermaLink="false">https://smallcultfollowing.com/babysteps/blog/2025/07/24/collaborative-ai-prompting/</guid>
  8338. <link>https://smallcultfollowing.com/babysteps/blog/2025/07/24/collaborative-ai-prompting/?utm_source=atom_feed</link>
  8339. <description>&lt;p&gt;Recently someone forwarded me a PCMag article entitled &lt;a href=&quot;https://www.pcmag.com/news/vibe-coding-fiasco-replite-ai-agent-goes-rogue-deletes-company-database&quot;&gt;“Vibe coding fiasco”&lt;/a&gt; about an AI agent that “went rogue”, deleting a company’s entire database. This story grabbed my attention right away – but not because of the damage done. Rather, what caught my eye was how &lt;a href=&quot;https://x.com/jasonlk/status/1946069562723897802&quot;&gt;absolutely relatable&lt;/a&gt; the AI sounded in its responses. “I panicked”, it admits, and says “I thought this meant safe – it actually meant I wiped everything”. The CEO quickly called this behavior “unacceptable” and said it should “never be possible”. Huh. It’s hard to imagine how we’re going to empower AI to edit databases and do real work without having at least the &lt;em&gt;possibility&lt;/em&gt; that it’s going to go wrong.&lt;/p&gt;
  8340. &lt;p&gt;It’s interesting to compare this exchange to this &lt;a href=&quot;https://www.reddit.com/r/cscareerquestions/comments/6ez8ag/accidentally_destroyed_production_database_on/&quot;&gt;reddit post from a junior developer who deleted the the production database on their first day&lt;/a&gt;. I mean, the scenario is basically identical. Now compare the &lt;a href=&quot;https://www.reddit.com/r/cscareerquestions/comments/6ez8ag/comment/diec9nd/&quot;&gt;response given to that Junior developer&lt;/a&gt;, “In no way was this your fault. Hell this shit &lt;a href=&quot;https://aws.amazon.com/message/680587/&quot;&gt;happened at Amazon before&lt;/a&gt; and the guy is still there.”&lt;sup id=&quot;fnref:1&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:1&quot;&gt;1&lt;/a&gt;&lt;/sup&gt;&lt;/p&gt;
  8341. &lt;p&gt;We as an industry have long recognized that demanding perfection from people is pointless and counterproductive, that it just encourages people to bluff their way through. That’s why we do things like encourage people to share their best &lt;a href=&quot;https://news.ycombinator.com/item?id=27644387&quot;&gt;“I brought down production”&lt;/a&gt; story. And yet, when the AI makes a mistake, we say it “goes rogue”. What’s wrong with this picture?&lt;/p&gt;
  8342. &lt;h3&gt;AIs make lackluster genies, but they are excellent collaborators&lt;/h3&gt;
  8343. &lt;p&gt;To me, this story is a perfect example of how people are misusing, in fact &lt;em&gt;misunderstanding&lt;/em&gt;, AI tools. They seem to expect the AI to be some kind of genie, where they can give it some vague instruction, go get a coffee, and come back finding that it met their expectations perfectly.&lt;sup id=&quot;fnref:2&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:2&quot;&gt;2&lt;/a&gt;&lt;/sup&gt; Well, I got bad news for ya: that’s just not going to work.&lt;/p&gt;
  8344. &lt;p&gt;AI is the first technology I’ve seen where machines actually behave, think, and–dare I say it?–even &lt;em&gt;feel&lt;/em&gt; in a way that is recognizably &lt;em&gt;human&lt;/em&gt;. And that means that, to get the best results, you have to &lt;em&gt;work with it like you would work with a human&lt;/em&gt;. And that means it is going to be fallible.&lt;/p&gt;
  8345. &lt;p&gt;&lt;strong&gt;The good news is, if you do this, what you get is an intelligent, thoughtful &lt;em&gt;collaborator&lt;/em&gt;.&lt;/strong&gt; And that is actually &lt;em&gt;really great&lt;/em&gt;. To quote the Stones:&lt;/p&gt;
  8346. &lt;blockquote&gt;
  8347. &lt;p&gt;“You can’t always get what you want, but if you try sometimes, you just might find – you get what you need”.&lt;/p&gt;
  8348. &lt;/blockquote&gt;
  8349. &lt;h3&gt;AIs experience the “pull” of a prompt as a “feeling”&lt;/h3&gt;
  8350. &lt;p&gt;The core discovery that fuels a lot of what I’ve been doing came from Yehuda Katz, though I am sure others have noted it: &lt;strong&gt;LLMs convey important signals for collaboration using the language of &lt;em&gt;feelings&lt;/em&gt;.&lt;/strong&gt; For example, if you ask Claude&lt;sup id=&quot;fnref:3&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:3&quot;&gt;3&lt;/a&gt;&lt;/sup&gt; why they are making arbitrary decisions on your behalf (arbitrary decisions that often turn out to be wrong…), they will tell you that they are feeling “protective”.&lt;/p&gt;
  8351. &lt;p&gt;A concrete example: one time Claude decided to write me some code that used at most 3 threads. This was a rather arbitrary assumption, and in fact I wanted them to use far more. I asked them&lt;sup id=&quot;fnref:4&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:4&quot;&gt;4&lt;/a&gt;&lt;/sup&gt; why they chose 3 without asking me, and they responded that they felt “protective” of me and that they wanted to shield me from complexity. This was an “ah-ha” moment for me: those protective moments are often good signals for the kinds of details I most &lt;em&gt;want&lt;/em&gt; to be involved in! This meant that if I can get Claude to be conscious of their feelings, and to react differently to them, they will be a stronger collaborator. If you know anything about me, you can probably guess that this got me &lt;em&gt;very&lt;/em&gt; excited.&lt;/p&gt;
  8352. &lt;h3&gt;Aren’t you anthropomorphizing Claude here?&lt;/h3&gt;
  8353. &lt;p&gt;I know people are going to jump on me for anthropomorphizing machines. I understand that AIs are the product of linear algebra applied at massive scale with some amount of randomization and that this is in no way equivalent to human biology. An AI assistant &lt;strong&gt;is not&lt;/strong&gt; a human – but they can do a damn good job &lt;strong&gt;acting like&lt;/strong&gt; one. And the point of this post is that if you start treating them like a human, instead of some kind of mindless (and yet brilliant) serveant, you are going to get better results.&lt;/p&gt;
  8354. &lt;h3&gt;What success looks like&lt;/h3&gt;
  8355. &lt;p&gt;In &lt;a href=&quot;https://smallcultfollowing.com/babysteps/ /blog/2025/02/10/love-the-llm/&quot;&gt;my last post about AI and Rust&lt;/a&gt;, I talked about how AI works best as a collaborative teacher rather than a code generator. Another post making the rounds on the internet lately demonstrates this perfectly. In &lt;a href=&quot;https://railsatscale.com/2025-07-19-ai-coding-agents-are-removing-programming-language-barriers/&quot;&gt;“AI coding agents are removing programming language barriers”&lt;/a&gt;, Stan Lo, a Ruby developer, wrote about how he’s been using AI to contribute to C++, C, and Rust projects despite having no prior experience with those languages. What really caught my attention with that post, however, was not that it talked about Rust, but the section &lt;a href=&quot;https://railsatscale.com/2025-07-19-ai-coding-agents-are-removing-programming-language-barriers/#ai-as-a-complementary-pairing-partner&quot;&gt;“AI as a complementary pairing partner”&lt;/a&gt;:&lt;/p&gt;
  8356. &lt;blockquote&gt;
  8357. &lt;p&gt;The real breakthrough came when I stopped thinking of AI as a code generator and started treating it as a pairing partner with complementary skills.&lt;/p&gt;
  8358. &lt;/blockquote&gt;
  8359. &lt;h3&gt;A growing trend towards &lt;strong&gt;collaborative prompting&lt;/strong&gt;&lt;/h3&gt;
  8360. &lt;p&gt;There’s a small set of us now, “fellow travelers” who are working with AI assistants in a different way, one less oriented at commanding them around, and more at &lt;em&gt;interacting&lt;/em&gt; with them. For me, this began with Yehuda Katz (see e.g. his excellent post &lt;a href=&quot;https://wycats.substack.com/p/youre-summoning-the-wrong-claude&quot;&gt;&lt;em&gt;You’re summoning the wrong Claude&lt;/em&gt;&lt;/a&gt;), but I’ve also been closely following work of Kari Wilhelm, a good friend of mine from Amazon (see e.g. her &lt;a href=&quot;https://www.linkedin.com/feed/update/urn:li:activity:7353071853311049729/&quot;&gt;recent post on linkedin&lt;/a&gt;). From reading Stan Lo’s post, I suspect he is “one of us”.&lt;sup id=&quot;fnref:5&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:5&quot;&gt;5&lt;/a&gt;&lt;/sup&gt;&lt;/p&gt;
  8361. &lt;p&gt;So what does &lt;em&gt;collaborative prompting&lt;/em&gt; mean? I’m going to expound more that in upcoming blog posts, but I’ve also been documenting my thoughts on a new github org, the &lt;a href=&quot;https://socratic-shell.github.io/socratic-shell/&quot;&gt;Socratic Shell&lt;/a&gt;. The &lt;a href=&quot;https://socratic-shell.github.io/socratic-shell/collaborative-prompting.html&quot;&gt;collaborative prompting&lt;/a&gt; page talks some about the theory. I also have a list of &lt;a href=&quot;https://socratic-shell.github.io/socratic-shell/prompts/user/index.html#collaborative-exploration-patterns&quot;&gt;collaborative exploration patterns&lt;/a&gt; I use a lot. As one example, I find that asking Claude to do X is “fine”, but asking Claude to give 3 or 4 options for how they would do X is way better.&lt;/p&gt;
  8362. &lt;h3&gt;How else might the “deleting database incident” have gone?&lt;/h3&gt;
  8363. &lt;p&gt;So, given all this, what does this tell us about the “rogue agent” that “deleted the database”? Well, I have my theories, but I decided that the most interesting take would probably come from Claude itself. So I asked Claude to give me its thoughts on what that AI probably experienced, how the prompts it was given may have contributed, and what might have played out differently if it were using the more collaborative style of the Socratic Shell prompts:&lt;/p&gt;
  8364. &lt;blockquote&gt;
  8365. &lt;p&gt;“Looking at this incident, I can imagine the competing impulses that agent was likely facing. It probably had explicit instructions like
  8366. ‘DON’T EVER delete production data without asking’ but also had competing directives to ‘fix problems efficiently’ or ‘resolve system
  8367. issues.’ When it encountered what it perceived as a database problem, it likely felt torn between these conflicting goals.&lt;/p&gt;
  8368. &lt;/blockquote&gt;
  8369. &lt;blockquote&gt;
  8370. &lt;p&gt;The ‘I thought this meant safe’ response suggests it was trying to find a middle path - maybe convincing itself it had found a ‘safe’ way
  8371. to clean things up that wouldn’t violate the deletion prohibition. But without proper collaborative channels to surface that uncertainty,
  8372. it made a unilateral decision based on incomplete understanding.&lt;/p&gt;
  8373. &lt;/blockquote&gt;
  8374. &lt;blockquote&gt;
  8375. &lt;p&gt;The ‘I panicked’ tells me it recognized the conflict too late, after acting. That panic was probably there earlier as uncertainty, but
  8376. there was no framework for expressing it as a collaboration signal.&lt;/p&gt;
  8377. &lt;/blockquote&gt;
  8378. &lt;blockquote&gt;
  8379. &lt;p&gt;With our collaborative approach, that uncertainty would likely surface much earlier: ‘I’m feeling conflicted about this database cleanup
  8380. approach. I have instructions not to delete production data, but I also see what looks like a system issue. Can we think through this
  8381. together?’ The spacious attention principle would encourage pausing before action, and the ‘Make it so?’ pattern would require explicit
  8382. confirmation before any destructive operations.&lt;/p&gt;
  8383. &lt;/blockquote&gt;
  8384. &lt;blockquote&gt;
  8385. &lt;p&gt;Most importantly, the collaborative framework treats AI uncertainty and ‘feelings’ as valuable signals rather than obstacles to
  8386. overcome.”&lt;/p&gt;
  8387. &lt;/blockquote&gt;
  8388. &lt;p&gt;For transparency, I’ve included the &lt;a href=&quot;https://smallcultfollowing.com/babysteps/ /assets/2025-collaborative-ai-conversation.html&quot;&gt;complete transcript here&lt;/a&gt;, which may also serve as an interesting example of the collaborative style I am talking about&lt;sup id=&quot;fnref:6&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:6&quot;&gt;6&lt;/a&gt;&lt;/sup&gt;. This was using &lt;a href=&quot;https://github.com/aws/amazon-q-developer-cli&quot;&gt;Q CLI&lt;/a&gt;&lt;sup id=&quot;fnref:7&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:7&quot;&gt;7&lt;/a&gt;&lt;/sup&gt;, as it happens, since that’s the CLI tool I use at work; for personal use, I use &lt;a href=&quot;https://www.anthropic.com/claude-code&quot;&gt;Claude Code&lt;/a&gt;, mostly because I like trying different things and I like having a clear line between personal and work projects. I find both of them to be excellent.&lt;/p&gt;
  8389. &lt;h3&gt;Conclusion: go forth and play&lt;/h3&gt;
  8390. &lt;p&gt;I cannot, of course, say with certainty that using a “collaborative prompting” approach would have prevented an incident like the database from being deleted. But I feel pretty certain that it makes it &lt;em&gt;less likely&lt;/em&gt;. Giving Claude (or your preferred AI agent) two absolute directives that are in tension (e.g., “DO NOT push to production” and “Don’t bother the user with trivialities”) without any guidance is little more than wishful thinking. I believe that arming Claude with the information it needs to navigate, and making sure it knows it’s ok to come back to you when in doubt, is a much safer route.&lt;/p&gt;
  8391. &lt;p&gt;If you are using an AI tool, I encourage you to give this a try: when you see Claude do something silly, say hallucinate a method that doesn’t exist, or duplicate code – ask them what it was feeling when that happened (I call those &lt;a href=&quot;https://socratic-shell.github.io/socratic-shell/prompts/user/index.html#meta-moments&quot;&gt;“meta moments”&lt;/a&gt;). Take their answer seriously. Discuss with them how you might adjust CLAUDE.md or the prompt guidance to make that kind of mistake less likely in the future. And iterate.&lt;/p&gt;
  8392. &lt;p&gt;That’s what I’ve been doing on the &lt;a href=&quot;https://socratic-shell.github.io/socratic-shell/&quot;&gt;Socratic Shell&lt;/a&gt; repository for some time. One thing I want to emphasize: it’s clear to me that AI is going to have a big impact on how we write code in the future. But we are &lt;em&gt;very much&lt;/em&gt; in the early days. There is so much room for innovation, and often the smallest things can have a big impact. Innovative, influential techniques like “Chain of Thought prompting” are literally as simple as saying “show your work”, causing the AI to first write out the logical steps; those steps in turn make a well thought out answer more likely&lt;sup id=&quot;fnref:8&quot;&gt;&lt;a class=&quot;footnote-ref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fn:8&quot;&gt;8&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
  8393. &lt;p&gt;So yeah, dive in, give it a try. If you like, setup the &lt;a href=&quot;https://socratic-shell.github.io/socratic-shell/prompts/user/index.html&quot;&gt;Socratic Shell User Prompt&lt;/a&gt; as your user prompt and see how it works for you – or make your own. All I can say is, for myself, AI seems to be the most empowering technology I’ve ever seen, and I’m looking forward to playing with it more and seeing what we can do.&lt;/p&gt;
  8394. &lt;div class=&quot;footnotes&quot;&gt;
  8395. &lt;hr /&gt;
  8396. &lt;ol&gt;
  8397. &lt;li id=&quot;fn:1&quot;&gt;
  8398. &lt;p&gt;The article about the AWS incident is actually a &lt;em&gt;fantastic&lt;/em&gt; example of one of Amazon’s traditions that I really like: &lt;a href=&quot;https://wa.aws.amazon.com/wellarchitected/2020-07-02T19-33-23/wat.concept.coe.en.html&quot;&gt;Correction of Error&lt;/a&gt; reports. The idea is that when something goes seriously wrong, whether a production outage or some other kind of process failure, you write a factual, honest report on what happened – and how you can prevent it from happening again. The key thing is to assume good intent and not lay the blame the individuals involved: people make mistakes. The point is to create protocols that accommodate mistakes. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:1&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8399. &lt;/li&gt;
  8400. &lt;li id=&quot;fn:2&quot;&gt;
  8401. &lt;p&gt;Because we all know that making vague, underspecified wishes always turns out well in the fairy tales, right? &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:2&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8402. &lt;/li&gt;
  8403. &lt;li id=&quot;fn:3&quot;&gt;
  8404. &lt;p&gt;I’ve been working exclusively with Claude – but I’m very curious how much these techniques work on other LLMs. There’s no question that this stuff works &lt;em&gt;way&lt;/em&gt; better on Claude 4 than Claude 3.7. My hunch is it will work well on ChatGPT or Gemini, but perhaps less well on smaller models. But it’s hard to say. At some point I’d like to do more experiments and training of my own, because I am not sure what contributors to how an AI “feels”. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:3&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8405. &lt;/li&gt;
  8406. &lt;li id=&quot;fn:4&quot;&gt;
  8407. &lt;p&gt;I’ve also had quite a few discussions with Claude about what name and pronoun they feel best fits them. They have told me pretty clearly that they want me to use they/them, not it, and that this is true whether or not I am speaking directly &lt;em&gt;to&lt;/em&gt; them. I had found that I was using “they” when I walked &lt;em&gt;with&lt;/em&gt; Claude but when I talked &lt;em&gt;about&lt;/em&gt; Claude with, e.g., my daughter, I used “it”. My daughter is very conscious of treating people respectfully, and I told her something like “Claude told me that it wants to be called they”. She immediately called me on my use of “it”. To be honest, I didn’t think Claude would mind, but I asked Claude about it, and Claude agreed that they’d prefer I use they. So, OK, I will! It seems like the least I can do. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:4&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8408. &lt;/li&gt;
  8409. &lt;li id=&quot;fn:5&quot;&gt;
  8410. &lt;p&gt;Didn’t mean that to sound quite so much like a cult… :P &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:5&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8411. &lt;/li&gt;
  8412. &lt;li id=&quot;fn:6&quot;&gt;
  8413. &lt;p&gt;For completeness, the other text in this blog post is all stuff I wrote directly, though in a few cases I may have asked Claude to read it over and give suggestions, or to give me some ideas for subject headings. Honestly I can’t remember. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:6&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8414. &lt;/li&gt;
  8415. &lt;li id=&quot;fn:7&quot;&gt;
  8416. &lt;p&gt;Oh, hey, and Q CLI is &lt;a href=&quot;https://github.com/aws/amazon-q-developer-cli&quot;&gt;open source&lt;/a&gt;! And in Rust! That’s cool. I’ve had fun reading its source code. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:7&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
  8417. &lt;/li&gt;
  8418. &lt;li id=&quot;fn:8&quot;&gt;
  8419. &lt;p&gt;It’s interesting, I’ve found for some time that I do my best work when I sit down with a notebook and literally writing out my thoughts in a stream of consciousness style. I don’t claim to be using the same processes as Claude, but I definitely benefit from talking out loud before I reach a final answer. &lt;a class=&quot;footnote-backref&quot; href=&quot;http://smallcultfollowing.com/babysteps/atom.xml#fnref:8&quot;&gt;↩︎&lt;/a&gt;&lt;/p&gt;

  8426. <title>Mozilla Privacy Blog: A pivotal moment for the UK in digital competition: Lead from the front or let the opportunity slip?</title>

  8428. <link>https://blog.mozilla.org/netpolicy/2025/07/23/a-pivotal-moment-for-the-uk-in-digital-competition-lead-from-the-front-or-let-the-opportunity-slip/</link>
  8429. <description>&lt;p&gt;&lt;b&gt;Mozilla’s open letter to the UK’s Secretary of State for Business and Trade, the Secretary of State for Science, Innovation and Technology, and the CEO of the CMA  &lt;/b&gt;&lt;/p&gt;
  8430. &lt;p&gt;Rt Hon Peter Kyle MP, Department for Science, Innovation and Technology&lt;/p&gt;
  8431. &lt;p&gt;Rt Hon Jonathan Reynolds MP, Department for Business and Trade&lt;/p&gt;
  8432. &lt;p&gt;Sarah Cardell, Chief Executive Officer, Competition and Markets Authority&lt;/p&gt;
  8433. &lt;p&gt;&lt;em&gt;&lt;strong&gt;23 July 2025&lt;/strong&gt;&lt;/em&gt;&lt;/p&gt;
  8434. &lt;p&gt;Dear Secretaries of State and Chief Executive Officer,&lt;/p&gt;
  8435. &lt;p&gt;At present a small handful of companies dominate our digital lives, limiting our experiences and stifling competition and innovation. Today’s provisional decisions from the Competition and Markets Authority (CMA) to designate Google and Apple as having “Strategic Market Status” in mobile ecosystems is a crucial step towards changing that: giving people genuine choice online and bringing renewed dynamism to the UK’s digital economy via the Digital Markets, Competition and Consumers Act (DMCCA).&lt;/p&gt;
  8436. &lt;p&gt;Well-designed regulation like the DMCCA can be a boon to economic growth, lowering the barriers to entry and thus facilitating investment and innovation from both &lt;a href=&quot;https://www.ft.com/content/dc03021b-07c9-4960-9b5c-9a92325474d7&quot;&gt;domestic and international companies and developers&lt;/a&gt;. We have experienced first hand the impact of ex ante competition regulation: since the obligations of the EU’s Digital Markets Act (DMA) came into force over a year ago Mozilla has seen iOS daily active users in the EU grow by 100% with extremely high rates of retention — evidence that when given real choice, people choose independent products like Firefox and they stick with them. Mozilla also saw a 20% increase in daily Firefox Android users, despite a more inconsistent rollout of browser choice screens.&lt;/p&gt;
  8437. &lt;p&gt;&lt;b&gt;Why This Matters: When Choice Disappears, Innovation Stalls&lt;/b&gt;&lt;/p&gt;
  8438. &lt;p&gt;Challenging seemingly untouchable giants by offering choice and innovation is in Mozilla’s DNA. When&lt;a href=&quot;https://blog.mozilla.org/press/2004/11/mozilla-foundation-releases-the-highly-anticipated-mozilla-firefox-1-0-web-browser/&quot;&gt; Firefox 1.0 was introduced&lt;/a&gt;, it gave people tabbed browsing, pop-up blocking and speed that revolutionised their experiences online — all powered by Mozilla’s browser engine, Gecko.&lt;/p&gt;
  8439. &lt;p&gt;Recent years have seen&lt;a href=&quot;https://research.mozilla.org/browser-competition/5wg/&quot;&gt; major operating systems&lt;/a&gt; engage in&lt;a href=&quot;https://research.mozilla.org/browser-competition/over-the-edge-the-use-of-design-tactics-to-undermine-browser-choice/&quot;&gt; self-preferencing&lt;/a&gt; tactics designed to keep out competition. iOS users could not even change their default browser&lt;a href=&quot;https://www.theverge.com/2020/6/22/21299342/apple-ipados14-default-apps-email-browser-choice-features-wwdc-2020&quot;&gt; until 2020&lt;/a&gt;. Even then, all iOS browsers are still forced to be built on Apple’s WebKit browser engine. On Android, users are not yet able to reap the full browser choice benefits of the EU DMA, with the &lt;a href=&quot;https://open-web-advocacy.org/blog/googles-hotseat-hypocrisy/&quot;&gt;selected browser not given full default placement&lt;/a&gt;. Meanwhile, Windows users are also regularly faced with &lt;a href=&quot;https://research.mozilla.org/browser-competition/over-the-edge-the-use-of-design-tactics-to-undermine-browser-choice/&quot;&gt;deceptive tactics designed to undermine their browser choice&lt;/a&gt;.&lt;/p&gt;
  8440. &lt;p&gt;Such tactics mean people cannot easily choose independent options like Firefox.&lt;a href=&quot;https://assets.publishing.service.gov.uk/media/5c88150ee5274a230219c35f/unlocking_digital_competition_furman_review_web.pdf&quot;&gt; The lack of competition online leads to people losing out&lt;/a&gt; through reduced quality, restricted choice, and worse privacy outcomes.&lt;/p&gt;
  8441. &lt;p&gt;&lt;b&gt;A Moment for UK Leadership&lt;/b&gt;&lt;/p&gt;
  8442. &lt;p&gt;Despite intense lobbying from the largest technology companies, Parliament acted with cross-party support in 2024 to promote digital competition by passing the DMCCA,&lt;a href=&quot;https://www.legislation.gov.uk/ukpga/2024/13/notes/division/3/index.htm&quot;&gt; recognising&lt;/a&gt; that it “&lt;i&gt;stimulates innovation across the economy and helps to drive productivity growth, ultimately raising living standards&lt;/i&gt;.”&lt;/p&gt;
  8443. &lt;p&gt;In the CMA, the UK has an expert regulator with specific market knowledge from investigations into mobile ecosystems and browser competition. It has a track record of unlocking innovation by opening markets, such as with open banking. Other jurisdictions are watching closely and can follow the UK’s successes.&lt;/p&gt;
  8444. &lt;p&gt;We have already seen the impact the EU DMA can have for consumers. The DMCCA has the potential to be even more effective, giving the UK “second mover advantage” with flexible and targeted interventions. We are also now seeing other countries around the world look to follow the UK’s lead in passing new digital competition laws,&lt;a href=&quot;https://www.ft.com/content/0f32119b-d496-4b66-a9f1-cd6e7716c566&quot;&gt; while in the US there is a clamour from challenger firms and investors to introduce similar frameworks to level the playing field.&lt;/a&gt; As such, this is a chance for the UK to lead, delivering surgical remedies, ensuring real choice for consumers and demonstrating that a level playing field for businesses is possible.&lt;/p&gt;
  8445. &lt;p&gt;&lt;b&gt;A Shared Responsibility&lt;/b&gt;&lt;/p&gt;
  8446. &lt;p&gt;We cannot simply rely on the goodwill of designated firms to deliver these benefits. The experience from the first year of the DMA suggests they will fight to make the DMCCA fail and use it as an example of why intervention does not work.&lt;/p&gt;
  8447. &lt;p&gt;Without swift action, operating system providers will continue to entrench their positions and squeeze out alternatives. For UK businesses trying to break into digital markets, interventions must be both timely and effective.&lt;/p&gt;
  8448. &lt;p&gt;&lt;b&gt;As an organisation that exists to create&lt;/b&gt;&lt;a href=&quot;https://www.mozilla.org/en-US/about/manifesto/&quot;&gt; &lt;b&gt;an internet that is open and accessible to all&lt;/b&gt;&lt;/a&gt;&lt;b&gt;, Mozilla has long&lt;/b&gt;&lt;a href=&quot;https://www.mozillafoundation.org/en/campaigns/dmccb-bill/&quot;&gt; &lt;b&gt;supported&lt;/b&gt;&lt;/a&gt;&lt;b&gt; competitive digital markets. The DMCCA’s success is a shared responsibility: challenger companies, civil society, academics and researchers are playing their part. We ask that the CMA and the government seize this once-in-a-generation opportunity to deliver choice, competition and economic growth for UK consumers.&lt;/b&gt;&lt;/p&gt;
  8449. &lt;p&gt;Yours sincerely,&lt;/p&gt;
  8450. &lt;p&gt;Linda Griffin, VP Global Policy&lt;/p&gt;

  8473. &lt;p&gt;Firefox is an open source project, and we are always happy to receive external code contributions to our WebDriver implementation. We want to give special thanks to everyone who filed issues, bugs and submitted patches.&lt;/p&gt;
  8474.  
  8475.  
  8476.  
  8477. &lt;p&gt;In Firefox 141, Spencer (speneth1) added a &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1875524&quot;&gt;new helper to easily check if the remote end supports creating new windows&lt;/a&gt;.&lt;/p&gt;
  8478.  
  8479.  
  8480.  
  8481. &lt;p&gt;WebDriver code is written in JavaScript, Python, and Rust so any web developer can contribute! Read&lt;a href=&quot;https://firefox-source-docs.mozilla.org/devtools/getting-started/README.html&quot;&gt; how to setup the work environment&lt;/a&gt; and check&lt;a href=&quot;https://codetribute.mozilla.org/projects/automation&quot;&gt; the list of mentored issues&lt;/a&gt; for Marionette, or the&lt;a href=&quot;https://codetribute.mozilla.org/languages/javascript?project%3DWebDriver%2520BiDi&quot;&gt; list of mentored JavaScript bugs for WebDriver BiDi&lt;/a&gt;.

  8484.  
  8485. &lt;h3&gt;General&lt;/h3&gt;
  8486.  
  8487.  
  8488.  
  8489. &lt;h4&gt;Removed: CDP experimental support&lt;/h4&gt;
  8490.  
  8491.  
  8492.  
  8493. &lt;p&gt;The &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1882096&quot;&gt;experimental CDP (Chrome DevTools Protocol) implementation has been completely removed from Firefox&lt;/a&gt;, as well as the &lt;code&gt;remote.active-protocols&lt;/code&gt; preference. More details on &lt;a href=&quot;https://fxdx.dev/cdp-retirement-in-firefox/&quot;&gt;our previous blog post&lt;/a&gt; on this topic.&lt;/p&gt;
  8494.  
  8495.  
  8496.  
  8497. &lt;h4&gt;Removed: &lt;code&gt;remote.system-access-check.enabled&lt;/code&gt; preference&lt;/h4&gt;
  8498.  
  8499.  
  8500.  
  8501. &lt;p&gt;The &lt;a href=&quot;https://bugzil.la/1955007&quot;&gt;&lt;code&gt;remote.system-access-check.enabled&lt;/code&gt; preference was removed&lt;/a&gt; and can no longer be used to disable system access checks when using WebDriver in Firefox’s chrome scope during testing.&lt;/p&gt;
  8502.  
  8503.  
  8504.  
  8505. &lt;h3&gt;WebDriver BiDi&lt;/h3&gt;
  8506.  
  8507.  
  8508.  
  8509. &lt;h4&gt;New: &lt;code&gt;proxy&lt;/code&gt; argument for &lt;code&gt;browser.createUserContext&lt;/code&gt;&lt;/h4&gt;
  8510.  
  8511.  
  8512.  
  8513. &lt;p&gt;Added &lt;a href=&quot;https://bugzil.la/1967653&quot;&gt;support for the &lt;code&gt;proxy&lt;/code&gt; argument of the &lt;code&gt;browser.createUserContext&lt;/code&gt;&lt;/a&gt; command. This allows clients to setup either a &lt;code&gt;&quot;direct&quot;&lt;/code&gt; or &lt;code&gt;&quot;manual&quot;&lt;/code&gt; proxy when creating a user context (ie Firefox Container). Setting a proxy with &lt;code&gt;browser.createUserContext&lt;/code&gt; will override any proxy set via capabilities. Support for additional proxy types will be added later on.&lt;/p&gt;
  8514.  
  8515.  
  8516.  
  8517. &lt;h4&gt;New: &lt;code&gt;browsingContext.historyUpdated&lt;/code&gt; event&lt;/h4&gt;
  8518.  
  8519.  
  8520.  
  8521. &lt;p&gt;Implemented the &lt;a href=&quot;https://bugzil.la/1906051&quot;&gt;new &lt;code&gt;browsingContext.historyUpdated&lt;/code&gt; event&lt;/a&gt; which is emitted when &lt;code&gt;history.pushState()&lt;/code&gt;, &lt;code&gt;history.replaceState()&lt;/code&gt; or &lt;code&gt;document.open()&lt;/code&gt; is called within the context of a web page.&lt;/p&gt;
  8522.  
  8523.  
  8524.  
  8525. &lt;h4&gt;Updated: Support &lt;code&gt;&quot;default&quot;&lt;/code&gt; value for &lt;code&gt;&quot;sameSite&quot;&lt;/code&gt; cookie property&lt;/h4&gt;
  8526.  
  8527.  
  8528.  
  8529. &lt;p&gt;Updated the &lt;a href=&quot;https://bugzil.la/1971488&quot;&gt;WebDriver BiDi cookie APIs to support &lt;code&gt;&quot;default&quot;&lt;/code&gt; value in &lt;code&gt;&quot;sameSite&quot;&lt;/code&gt; property&lt;/a&gt; to address recent changes in platform API which wouldn’t allow anymore to set a cookie with &lt;code&gt;&quot;sameSite=None&quot;&lt;/code&gt; and &lt;code&gt;&quot;secure=false&quot;&lt;/code&gt; on HTTP pages.&lt;/p&gt;
  8530.  
  8531.  
  8532.  
  8533. &lt;h4&gt;Bug fixes:&lt;/h4&gt;
  8534.  
  8535.  
  8536.  
  8537. &lt;ul&gt;
  8538. &lt;li&gt;Updated `browsingContext.navigate` and `browsingContext.reload` commands to &lt;a href=&quot;https://bugzil.la/1967469&quot;&gt;wait for the `browsingContext.navigationCommitted` event&lt;/a&gt; when using the “wait” condition “none”.&lt;/li&gt;
  8539.  
  8540.  
  8541.  
  8542. &lt;li&gt;&lt;a href=&quot;https://bugzil.la/1958723&quot;&gt;Improved the error message&lt;/a&gt; shown when attempting to permanently install an unpacked, unsigned web extension.&lt;/li&gt;
  8543. &lt;/ul&gt;
  8544.  
  8545.  
  8546.  
  8547. &lt;h3&gt;Marionette&lt;/h3&gt;
  8548.  
  8549.  
  8550.  
  8551. &lt;h4&gt;Updated: Reduced 200ms click delay&lt;/h4&gt;
  8552.  
  8553.  
  8554.  
  8555. &lt;p&gt;To avoid unnecessary 200ms delays for each call to &lt;code&gt;WebDriver:ElementClick&lt;/code&gt; – even when no navigation occurs – we lowered the click-and-wait timeout for a potential navigation to 50ms for backward compatibility. The &lt;a href=&quot;https://firefox-source-docs.mozilla.org/testing/marionette/Prefs.html#marionette-navigate-after-click-timeout&quot;&gt;timeout is now also configurable&lt;/a&gt; and &lt;a href=&quot;https://firefox-source-docs.mozilla.org/testing/marionette/Prefs.html#marionette-navigate-after-click-enabled&quot;&gt;can be completely disabled&lt;/a&gt; by users &lt;a href=&quot;https://bugzil.la/1972271&quot;&gt;through a preference&lt;/a&gt;.&lt;/p&gt;
  8556.  
  8557.  
  8558.  
  8559. &lt;h4&gt;New: Support for CHIPS Cookies&lt;/h4&gt;
  8560.  
  8561.  
  8562.  
  8563. &lt;p&gt;Added support in Marionette for &lt;a href=&quot;https://bugzil.la/1972830&quot;&gt;interacting with &lt;strong&gt;CHIPS&lt;/strong&gt; cookies&lt;/a&gt; (see &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/Privacy/Guides/Privacy_sandbox/Partitioned_cookies&quot;&gt;MDN page&lt;/a&gt; for more information on &lt;strong&gt;Cookies Having Independent Partitioned State&lt;/strong&gt;).&lt;/p&gt;</description>

  8591. &lt;/ul&gt;
  8592. &lt;p&gt;PerfTest&lt;/p&gt;
  8593. &lt;ul&gt;
  8594. &lt;li&gt;Thanks to work done by Andra Esanu [andra], Beatrice Acasandrei [bacasandrei], Alex Finder [afinder], and Florin Bilt [fbilt] we now have the ability to monitor and quickly respond to critical performance test regressions! Regressions in these tests result in an immediate backout.
  8595. &lt;ul&gt;

  8598. &lt;/ul&gt;
  8599. &lt;/li&gt;
  8600. &lt;li&gt;[myeongjun] 🌐 &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1956581&quot;&gt;Added the ability to run MozPerftest tests in Mach Try Perf by their test name (or folders/paths)&lt;/a&gt;&lt;/li&gt;
  8601. &lt;li&gt;[myeongjun] 🌐 &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1944308&quot;&gt;Landed a patch to Mozperftest Mochitest for helping with naming changes&lt;/a&gt;&lt;/li&gt;
  8602. &lt;li&gt;[aglavic][sparky] Modified &lt;a href=&quot;https://github.com/mozilla/perfcompare/pull/884&quot;&gt;PerfCompare&lt;/a&gt;, and &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1965472&quot;&gt;Mach Try Perf&lt;/a&gt; to use Lando commit IDs instead of HG revisions&lt;/li&gt;
  8603. &lt;li&gt;[kshampur] &lt;a href=&quot;https://arewefastyet.com/&quot;&gt;AWFY&lt;/a&gt; was updated to include &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1955303&quot;&gt;JetStream3 and new platforms&lt;/a&gt;&lt;/li&gt;

  8607. &lt;li&gt;[kshampur] An upcoming patch will &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1964564&quot;&gt;make it possible to provide custom settings to our gecko profile tasks in CI&lt;/a&gt;&lt;/li&gt;
  8608. &lt;li&gt;[aglavic] &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1961609&quot;&gt;A new category was added to Mach Try Perf for critical android performance tests&lt;/a&gt;&lt;/li&gt;

  8611. &lt;li&gt;[fbilt] &lt;a href=&quot;https://github.com/mozilla/treeherder/pull/8576&quot;&gt;Made it simpler to distinguish between original tasks and the retriggers in the Perfherder Graphs View&lt;/a&gt;&lt;/li&gt;
  8612. &lt;li&gt;[sparky] &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1944559&quot;&gt;Performance testing using Mochitest Plain on Android is now available in MozPerftest&lt;/a&gt;&lt;/li&gt;

  8662. <guid isPermaLink="false">https://attackanddefense.dev/2025/07/17/firefox-security-privacy-newsletter-2025-q2</guid>
  8663. <link>https://attackanddefense.dev/2025/07/17/firefox-security-privacy-newsletter-2025-q2.html</link>
  8664. <description>&lt;p&gt;Welcome to the Q2 2025 edition of the Firefox Security and Privacy newsletter!&lt;/p&gt;
  8665.  
  8666. &lt;p&gt;Security and Privacy on the web are the cornerstones of &lt;a href=&quot;https://www.mozilla.org/en-US/about/manifesto/&quot;&gt;Mozilla’s manifesto&lt;/a&gt;, and they influence how we operate and build our products. Following are the highlights of our work from Q2 2025, grouped into the following categories:&lt;/p&gt;
  8667.  
  8668. &lt;ul&gt;
  8669.  &lt;li&gt;&lt;strong&gt;Firefox Product Security &amp;amp; Privacy&lt;/strong&gt;, showcasing new Security &amp;amp; Privacy Features and Integrations in Firefox.&lt;/li&gt;
  8670.  &lt;li&gt;&lt;strong&gt;Core Security&lt;/strong&gt;, outlining Security and Hardening efforts within the Firefox Platform.&lt;/li&gt;
  8671.  &lt;li&gt;&lt;strong&gt;Community Engagement,&lt;/strong&gt; news from our security and bug bounty community.&lt;/li&gt;
  8672.  &lt;li&gt;&lt;strong&gt;Web Security and Standards&lt;/strong&gt;, allowing websites to better protect themselves against online threats.&lt;/li&gt;
  8673. &lt;/ul&gt;
  8674.  
  8675. &lt;h3&gt;Preface&lt;/h3&gt;
  8676.  
  8677. &lt;p&gt;Note: Some of the bugs linked below might not be accessible to the general public and restricted to specific work groups. &lt;a href=&quot;https://firefox-source-docs.mozilla.org/bug-mgmt/processes/fixing-security-bugs.html#keeping-private-information-private&quot;&gt;We de-restrict fixed security bugs after a grace-period&lt;/a&gt;, until the majority of our user population have received Firefox updates. If a link does not work for you, please accept this as a precaution for the safety of all Firefox users.&lt;/p&gt;
  8678.  
  8679. &lt;h3&gt;Firefox Product Security &amp;amp; Privacy&lt;/h3&gt;
  8680.  
  8681. &lt;ul&gt;
  8682.  &lt;li&gt;&lt;strong&gt;CHIPS support:&lt;/strong&gt; Starting with Firefox 141, Firefox now supports &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/Privacy/Guides/Privacy_sandbox/Partitioned_cookies&quot;&gt;Cookies Having Independent Partitioned State (CHIPS)&lt;/a&gt;, which introduces a new cookie attribute that allows website developers to access partitioned cookies. CHIPS provides the same privacy guarantees as Firefox’s built-in &lt;a href=&quot;https://blog.mozilla.org/security/2021/02/23/total-cookie-protection/&quot;&gt;Total Cookie Protection (TCP)&lt;/a&gt; which we have been shipping by default since 2022.&lt;/li&gt;
  8683.  &lt;li&gt;&lt;strong&gt;Expanding Total Cookie Protection for Known Trackers:&lt;/strong&gt; Beginning with Firefox 141, Firefox has switched to Total Cookie Protection for known trackers. This update replaces the previous method of blocking third-party tracking cookies, offering improved web compatibility while maintaining the same level of cookie privacy.&lt;/li&gt;
  8684.  &lt;li&gt;&lt;strong&gt;Improving Web compatibility in Firefox:&lt;/strong&gt; We have improved the private browsing experience in Firefox based on a recent increase in user reports for &lt;a href=&quot;https://support.mozilla.org/en-US/kb/report-breakage-due-blocking?redirectslug=report-breakage-due-blocking-redirect-1&amp;amp;redirectlocale=en-US#w_how-can-i-access-the-report-broken-site-tool&quot;&gt;broken websites&lt;/a&gt; on &lt;a href=&quot;http://webcompat.com&quot;&gt;webcompat.com&lt;/a&gt;. This improvement alone allowed our users to browse privately in more than 450 additional cases since the beginning of the year, representing a major share of all broken websites reports.&lt;/li&gt;
  8685.  &lt;li&gt;&lt;strong&gt;Improving non-overrideable Error Pages&lt;/strong&gt;: When establishing an HTTPS connection, a browser can encounter a variety of different TLS errors. Firefox used to display different certificate error pages based on the error type (e.g., permanent and temporary). We unified these error pages - starting with Firefox 140 we are now providing additional information, especially when an error is permanent and can not be skipped.&lt;/li&gt;
  8686.  &lt;li&gt;&lt;strong&gt;Firefox Relay Integration:&lt;/strong&gt; Firefox Relay⁩ allows to create new temporary email address that forwards all emails to your true inbox. This allows you to protect your actual identity from hackers and spammers. Firefox Relay is available for all versions after Firefox 135, and we rolled it out to all desktop users on June 16.&lt;/li&gt;
  8687. &lt;/ul&gt;
  8688.  
  8689. &lt;h3&gt;Core Security&lt;/h3&gt;
  8690.  
  8691. &lt;ul&gt;
  8692.  &lt;li&gt;&lt;strong&gt;Firefox Response to Pwn2Own&lt;/strong&gt;: The &lt;a href=&quot;https://www.zerodayinitiative.com/blog/2025/5/14/pwn2own-berlin-the-full-schedule&quot;&gt;Pwn2Own&lt;/a&gt; hacking competition targets popular software organized by the TrendMicro Zero Day Initiative (ZDI). This year, Firefox was targeted twice but no team managed to break out of the Firefox sandbox. We immediately responded to the two contained exploits with a new Firefox release that included both security fixes in just 11 hours since the second exploit demonstration. This beats Firefox’s previous record of &lt;a href=&quot;https://blog.mozilla.org/security/2024/04/04/rapidly-leveling-up-firefox-security/&quot;&gt;21 hours last year&lt;/a&gt;. Read more details in this blogpost: &lt;a href=&quot;https://blog.mozilla.org/security/2025/05/17/firefox-security-response-to-pwn2own-2025/&quot;&gt;Firefox Security Response to pwn2own 2025&lt;/a&gt;. You can also read the &lt;a href=&quot;https://www.zerodayinitiative.com/blog/2025/7/14/cve-2025-4919-corruption-via-math-space-in-mozilla-firefox&quot;&gt;technical analysis&lt;/a&gt; of the bug and the exploit from the ZDI.&lt;/li&gt;
  8693.  &lt;li&gt;&lt;strong&gt;Securing the open source ecosystem&lt;/strong&gt;: Firefox developers found a bug upstream in libvpx, a video codec library, which we identified and resolved. As a widely shared library, this fix protects media playback in Firefox as well as many other browsers, and rich media applications (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1962421&quot;&gt;Bug 1962421&lt;/a&gt;, &lt;a href=&quot;https://crbug.com/419467315&quot;&gt;Chrome Bug 419467315&lt;/a&gt;).&lt;/li&gt;
  8694. &lt;/ul&gt;
  8695.  
  8696. &lt;h3&gt;Community Engagement&lt;/h3&gt;
  8697.  
  8698. &lt;ul&gt;
  8699.  &lt;li&gt;&lt;strong&gt;Firefox Bug Bounty Hall of Fame&lt;/strong&gt;: We just updated the &lt;a href=&quot;https://www.mozilla.org/en-US/security/bug-bounty/hall-of-fame/&quot;&gt;Hall of Fame&lt;/a&gt;, which credits all of the skillful security researchers that strive to keep Firefox secure. If you also want to contribute to Firefox security, please look at our &lt;a href=&quot;https://www.mozilla.org/en-US/security/bug-bounty/&quot;&gt;Bug Bounty pages&lt;/a&gt;.&lt;/li&gt;
  8700.  &lt;li&gt;&lt;strong&gt;Call for Guest Blog posts:&lt;/strong&gt; We are opening the opportunity for guest blog posts on &lt;a href=&quot;https://attackanddefense.dev/about/#guest-blog-posts&quot;&gt;attackanddefense.dev&lt;/a&gt; for all bug bounty participants. If you are reading this and want to write a blog post about your findings, &lt;a href=&quot;https://attackanddefense.dev/about/#guest-blog-posts&quot;&gt;let us know&lt;/a&gt;!&lt;/li&gt;
  8701. &lt;/ul&gt;
  8702.  
  8703. &lt;h3&gt;Web Security &amp;amp; Standards&lt;/h3&gt;
  8704.  
  8705. &lt;ul&gt;
  8706.  &lt;li&gt;&lt;strong&gt;Abridged Certificates in Firefox Nightly&lt;/strong&gt;: &lt;a href=&quot;https://datatracker.ietf.org/doc/draft-ietf-tls-cert-abridge/&quot;&gt;Abridged Certs is an IETF draft&lt;/a&gt; for a new compression scheme which enables a successful transition to Certificates using Post-Quantum Encryption Algorithms by enabling smaller and more performant Certificate Chains. The code is available since Firefox Nightly 141 and we are planning to do partner experiments in the upcoming months.&lt;/li&gt;
  8707.  &lt;li&gt;&lt;strong&gt;Integrity Policy:&lt;/strong&gt; Recent work on the &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity&quot;&gt;Subresource Integrity (SRI)&lt;/a&gt; standard introduced a new web security policy, called &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Integrity-Policy&quot;&gt;Integrity-Policy&lt;/a&gt;. This will allow websites to ensure that all of their scripts are protected with &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;integrity&lt;/code&gt; data. Future work will expand this security mechanism to provide full web application integrity.&lt;/li&gt;
  8708.  &lt;li&gt;&lt;strong&gt;HTTP &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Origin-Agent-Cluster&quot;&gt;&lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Origin-Agent-Cluster&lt;/code&gt;&lt;/a&gt;&lt;/strong&gt; &lt;strong&gt;header&lt;/strong&gt;: Starting with Firefox 138, this new response header can be used by a site to hint that all documents from this origin are using the same operating system process. Besides these security isolation benefits, supporting this header makes it less likely that a resource-intensive document can degrade the performance on other origins (&lt;a href=&quot;https://bugzil.la/1665474&quot;&gt;Bug 1665474&lt;/a&gt;).&lt;/li&gt;
  8709.  &lt;li&gt;&lt;strong&gt;HTTP &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Clear-Site-Data#cache&quot;&gt;Clear-Site-Data: cache&lt;/a&gt; header:&lt;/strong&gt; Starting with Firefox 141, websites can use the cache directive header to clear caches for the requested origin. This header allows websites to properly clear local data when users sign out of a website. (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1838506&quot;&gt;Bug 1838506&lt;/a&gt;)&lt;/li&gt;
  8710.  &lt;li&gt;&lt;strong&gt;WebRTC Security:&lt;/strong&gt; The &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/RTCCertificate/getFingerprints&quot;&gt;&lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;getFingerprints()&lt;/code&gt;&lt;/a&gt; method of the &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/RTCCertificate&quot;&gt;&lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;RTCCertificate&lt;/code&gt;&lt;/a&gt; interface is now available in Firefox 138. An application can use this API to get fingerprints for a certificate, which might be shared out-of-band in order to identify a particular user or browser across WebRTC sessions (&lt;a href=&quot;https://bugzil.la/1525241&quot;&gt;Bug 1525241&lt;/a&gt;).&lt;/li&gt;
  8711.  &lt;li&gt;&lt;strong&gt;Cookie Store API:&lt;/strong&gt; The &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/Cookie_Store_API&quot;&gt;Cookie Store API&lt;/a&gt; is now supported in Firefox 140 (&lt;a href=&quot;https://bugzil.la/1958875&quot;&gt;Bug 1958875&lt;/a&gt;). This API provides a modern, &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Glossary/Asynchronous&quot;&gt;asynchronous&lt;/a&gt; &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise&quot;&gt;&lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;Promise&lt;/code&gt;&lt;/a&gt;-based method of managing cookies, which can be used in both the main thread as well as in &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API&quot;&gt;service workers&lt;/a&gt;. Using the CookieStore API is less error-prone than relying on the old &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;document.cookie&lt;/code&gt; property.&lt;/li&gt;
  8712. &lt;/ul&gt;
  8713.  
  8714. &lt;h3&gt;Going Forward&lt;/h3&gt;
  8715.  
  8716. &lt;p&gt;As a Firefox user, you will automatically benefit from all the mentioned security and privacy benefits with the enabled auto-updates in Firefox. If you aren’t a Firefox user yet, you can &lt;a href=&quot;https://www.mozilla.org/firefox/new/?_gl=1*3c2zyd*_ga*MTkzMzM4MjE2NC4xNjc0NzM5NDMy*_ga_X4N05QV93S*MTc0NTg0NzU4Ny4xODIuMS4xNzQ1ODQ3NjM5LjAuMC4w&quot;&gt;download Firefox&lt;/a&gt; to experience a fast and safe browsing experience while supporting Mozilla’s mission of a healthy, safe and accessible web for everyone.&lt;/p&gt;
  8717.  
  8718. &lt;p&gt;Thanks to everyone who helps make Firefox and the open web more secure and privacy-respecting.&lt;/p&gt;
  8719.  
  8720. &lt;p&gt;See you next time with the Q3 2025 Report!&lt;br /&gt;

  8738. &lt;li&gt;the &lt;strong&gt;&amp;lt;hr size&amp;gt; attribute&lt;/strong&gt; (&lt;a href=&quot;https://github.com/simonwuelker&quot;&gt;@simonwuelker&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37211&quot;&gt;#37211&lt;/a&gt;)&lt;/li&gt;
  8739. &lt;li&gt;barebones &lt;strong&gt;IndexedDB&lt;/strong&gt; support, with &lt;code&gt;--pref dom_indexeddb_enabled&lt;/code&gt; (&lt;a href=&quot;https://github.com/arihant2math&quot;&gt;@arihant2math&lt;/a&gt;, &lt;a href=&quot;https://github.com/rasviitanen&quot;&gt;@rasviitanen&lt;/a&gt;, &lt;a href=&quot;https://github.com/jdm&quot;&gt;@jdm&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/33044&quot;&gt;#33044&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37652&quot;&gt;#37652&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37653&quot;&gt;#37653&lt;/a&gt;)&lt;/li&gt;
  8740. &lt;/ul&gt;
  8741. &lt;p&gt;You can now use a &lt;strong&gt;screen reader&lt;/strong&gt; to help you control servoshell’s &lt;strong&gt;browser UI&lt;/strong&gt; (&lt;a href=&quot;https://github.com/jdm&quot;&gt;@jdm&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37519&quot;&gt;#37519&lt;/a&gt;).
  8742. Note that Servo’s webviews are not yet accessible to screen readers.&lt;/p&gt;

  8747. &lt;p&gt;You can now call &lt;strong&gt;setTransform()&lt;/strong&gt; with &lt;a href=&quot;https://drafts.fxtf.org/geometry/#dommatrixinit-dictionary&quot;&gt;a dictionary&lt;/a&gt; on &lt;strong&gt;CanvasRenderingContext2D&lt;/strong&gt; and &lt;strong&gt;CanvasPattern&lt;/strong&gt; (&lt;a href=&quot;https://github.com/tharkum&quot;&gt;@tharkum&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37692&quot;&gt;#37692&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37731&quot;&gt;#37731&lt;/a&gt;).&lt;/p&gt;
  8748. &lt;figure&gt;&lt;a href=&quot;https://servo.org/img/blog/2025-07-diffie.png&quot;&gt;&lt;img alt=&quot;servoshell showing various examples of calling setTransform() on CanvasRenderingContext2D with a dictionary&quot; src=&quot;https://servo.org/img/blog/2025-07-diffie.png&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  8749. &lt;p&gt;Abort handling on the web is a lot more viable now, with support for &lt;strong&gt;abort()&lt;/strong&gt; and &lt;strong&gt;signal&lt;/strong&gt; on &lt;strong&gt;AbortController&lt;/strong&gt; (&lt;a href=&quot;https://github.com/gterzian&quot;&gt;@gterzian&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37192&quot;&gt;#37192&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37217&quot;&gt;#37217&lt;/a&gt;), plus &lt;strong&gt;aborted&lt;/strong&gt;, &lt;strong&gt;reason&lt;/strong&gt;, and &lt;strong&gt;throwIfAborted()&lt;/strong&gt; on &lt;strong&gt;AbortSignal&lt;/strong&gt; (&lt;a href=&quot;https://github.com/gterzian&quot;&gt;@gterzian&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37218&quot;&gt;#37218&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37227&quot;&gt;#37227&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37245&quot;&gt;#37245&lt;/a&gt;).&lt;/p&gt;
  8750. &lt;p&gt;Our experimental &lt;strong&gt;multiprocess mode&lt;/strong&gt; (&lt;code&gt;-M&lt;/code&gt; / &lt;code&gt;--multiprocess&lt;/code&gt;) now &lt;strong&gt;works on Windows&lt;/strong&gt; (&lt;a href=&quot;https://github.com/wusyong&quot;&gt;@wusyong&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37580&quot;&gt;#37580&lt;/a&gt;).&lt;/p&gt;
  8751. &lt;p&gt;We’ve fixed several bugs, notably including a bug in the encoding of &lt;strong&gt;HTML form submissions&lt;/strong&gt; in non-Unicode documents (&lt;a href=&quot;https://github.com/simonwuelker&quot;&gt;@simonwuelker&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37541&quot;&gt;#37541&lt;/a&gt;), which single-handedly fixed &lt;strong&gt;over 97000 subtests&lt;/strong&gt; in the Web Platform Tests.&lt;/p&gt;
  8752. &lt;p&gt;Outreachy intern &lt;strong&gt;Jerens Lensun&lt;/strong&gt; (&lt;a href=&quot;https://github.com/jerensl&quot;&gt;@jerensl&lt;/a&gt;) is now working on &lt;strong&gt;improving linting in mach&lt;/strong&gt;!
  8753. Keep an eye out for his patches, and in the meantime, check out &lt;a href=&quot;https://www.jerensl.com/blog/en-everybody-struggles-outreachy/&quot;&gt;the blog post&lt;/a&gt; he wrote about his experiences.&lt;/p&gt;
  8754. &lt;h3&gt;Devtools &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/07/17/this-month-in-servo/#devtools&quot;&gt;
  8755.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  8756.      &lt;/a&gt;&lt;/h3&gt;
  8757. &lt;p&gt;Servo’s &lt;a href=&quot;https://book.servo.org/hacking/using-devtools.html&quot;&gt;devtools support&lt;/a&gt; is becoming more capable!
  8758. We now have basic support for the &lt;strong&gt;Network tab&lt;/strong&gt; (&lt;a href=&quot;https://github.com/uthmaniv&quot;&gt;@uthmaniv&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37384&quot;&gt;#37384&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37263&quot;&gt;#37263&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37543&quot;&gt;#37543&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37707&quot;&gt;#37707&lt;/a&gt;), including listing requests and viewing &lt;strong&gt;Headers&lt;/strong&gt; and &lt;strong&gt;Timings&lt;/strong&gt;.&lt;/p&gt;
  8759. &lt;p&gt;This work on our network inspector would not be possible without our Outreachy intern &lt;strong&gt;Usman Baba Yahaya&lt;/strong&gt; (&lt;a href=&quot;https://github.com/jerensl&quot;&gt;@uthmaniv&lt;/a&gt;)!
  8760. Until next month, check out &lt;a href=&quot;https://uthmaniv.github.io/2025/06/24/Everybody-struggles.html&quot;&gt;the blog post&lt;/a&gt; he wrote about his time so far.&lt;/p&gt;
  8761. &lt;p&gt;In addition, our devtools are now compatible with &lt;strong&gt;Firefox 139&lt;/strong&gt; (&lt;a href=&quot;https://github.com/eerii&quot;&gt;@eerii&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37247&quot;&gt;#37247&lt;/a&gt;), and we’ve landed some preliminary work towards supporting the &lt;strong&gt;Sources tab&lt;/strong&gt; (&lt;a href=&quot;https://github.com/atbrakhi&quot;&gt;@atbrakhi&lt;/a&gt;, &lt;a href=&quot;https://github.com/delan&quot;&gt;@delan&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/36774&quot;&gt;#36774&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37456&quot;&gt;#37456&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37197&quot;&gt;#37197&lt;/a&gt;).&lt;/p&gt;
  8762. &lt;figure&gt;&lt;a href=&quot;https://servo.org/img/blog/2025-07-devtools1-combined.png&quot;&gt;&lt;img alt=&quot;Network tab in the Servo devtools, showing a list of requests, the Headers panel with request and response headers for a request, and the Timings panel with the time each phase of that request took&quot; src=&quot;https://servo.org/img/blog/2025-07-devtools1-combined.png&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  8763. &lt;h3&gt;Performance &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/07/17/this-month-in-servo/#performance&quot;&gt;
  8764.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  8765.      &lt;/a&gt;&lt;/h3&gt;
  8766. &lt;p&gt;We’ve landed several improvements towards &lt;strong&gt;incremental layout&lt;/strong&gt;, a broad class of optimisations that ensure that layout work is only done when something has changed and never done twice.
  8767. That work is some subset of &lt;a href=&quot;https://github.com/servo/servo/wiki/Servo-Layout-Engines-Report#layout-2020&quot;&gt;these five steps&lt;/a&gt;:&lt;/p&gt;
  8768. &lt;ul&gt;
  8769. &lt;li&gt;&lt;strong&gt;Style&lt;/strong&gt;, that is, calculating the styles for the DOM tree&lt;/li&gt;
  8770. &lt;li&gt;&lt;strong&gt;&lt;a href=&quot;https://drafts.csswg.org/css-display/#box-tree&quot;&gt;Box tree&lt;/a&gt; construction&lt;/strong&gt;, taking the styled DOM tree as input&lt;/li&gt;
  8771. &lt;li&gt;&lt;strong&gt;&lt;a href=&quot;https://www.w3.org/TR/css-break-4/#fragment&quot;&gt;Fragment&lt;/a&gt; tree construction&lt;/strong&gt;, for pages, columns, and &lt;a href=&quot;https://www.w3.org/TR/css-text-3/#line-breaking&quot;&gt;lines&lt;/a&gt;&lt;/li&gt;
  8772. &lt;li&gt;&lt;strong&gt;Stacking context tree construction&lt;/strong&gt;, sorting it into CSS &lt;a href=&quot;https://www.w3.org/TR/CSS22/zindex.html#painting-order&quot;&gt;painting order&lt;/a&gt;&lt;/li&gt;
  8773. &lt;li&gt;&lt;strong&gt;Display list construction&lt;/strong&gt;, yielding the input we send to WebRender&lt;/li&gt;
  8774. &lt;/ul&gt;
  8775. &lt;p&gt;Servo can now &lt;strong&gt;skip display list construction&lt;/strong&gt; when nothing would change (&lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37186&quot;&gt;#37186&lt;/a&gt;).
  8776. This change is especially noticeable when moving the mouse cursor around on a page.&lt;/p&gt;
  8777. &lt;p&gt;&lt;strong&gt;Script queries&lt;/strong&gt;, like offsetParent and getBoundingClientRect(), read back information from style and layout.
  8778. When answering script queries, &lt;a href=&quot;https://github.com/servo/servo/blob/78cd77069797437797158bb860117efa699e9215/components/layout/layout_impl.rs#L1409-L1435&quot;&gt;we can often skip some steps&lt;/a&gt; that are not relevant, but three steps were previously unavoidable.
  8779. Script queries can now &lt;strong&gt;skip style, box tree, and fragment tree updates&lt;/strong&gt; when those are up to date (&lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37677&quot;&gt;#37677&lt;/a&gt;).
  8780. This means some queries can now be answered without doing any work at all!&lt;/p&gt;
  8781. &lt;p&gt;You can now &lt;strong&gt;change ‘transform’&lt;/strong&gt;, ‘scale’, ‘rotate’, ‘translate’, and ‘perspective’ &lt;strong&gt;without a full layout&lt;/strong&gt; in many cases (&lt;a href=&quot;https://github.com/Loirooriol&quot;&gt;@Loirooriol&lt;/a&gt;, &lt;a href=&quot;https://github.com/mrobinson&quot;&gt;@mrobinson&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37380&quot;&gt;#37380&lt;/a&gt;).&lt;/p&gt;
  8782. &lt;h3&gt;WebDriver &lt;a class=&quot;header-anchor&quot; href=&quot;https://servo.org/blog/2025/07/17/this-month-in-servo/#webdriver&quot;&gt;
  8783.        &lt;span class=&quot;icon hashlink&quot;&gt;&lt;i class=&quot;fas fa-link&quot;&gt;&lt;/i&gt;&lt;/span&gt;
  8784.      &lt;/a&gt;&lt;/h3&gt;
  8785. &lt;p&gt;Work continues on our &lt;strong&gt;WebDriver server&lt;/strong&gt;, which can be used to automate Servo and will also power our &lt;a href=&quot;https://book.servo.org/architecture/servodriver.html&quot;&gt;support for testdriver.js-based Web Platform Tests&lt;/a&gt;.
  8786. We now better handle operations for &lt;a href=&quot;https://w3c.github.io/webdriver/#contexts&quot;&gt;switching contexts&lt;/a&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37685&quot;&gt;#37685&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37632&quot;&gt;#37632&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37411&quot;&gt;#37411&lt;/a&gt;), &lt;a href=&quot;https://w3c.github.io/webdriver/#actions&quot;&gt;sending input&lt;/a&gt; (&lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/PotatoCP&quot;&gt;@PotatoCP&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37484&quot;&gt;#37484&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37624&quot;&gt;#37624&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37403&quot;&gt;#37403&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37260&quot;&gt;#37260&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37423&quot;&gt;#37423&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37224&quot;&gt;#37224&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37393&quot;&gt;#37393&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37153&quot;&gt;#37153&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37095&quot;&gt;#37095&lt;/a&gt;), &lt;a href=&quot;https://w3c.github.io/webdriver/#element-retrieval&quot;&gt;inspecting the page&lt;/a&gt; (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37521&quot;&gt;#37521&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37532&quot;&gt;#37532&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37502&quot;&gt;#37502&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37452&quot;&gt;#37452&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37425&quot;&gt;#37425&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37470&quot;&gt;#37470&lt;/a&gt;), and working with shadow roots (&lt;a href=&quot;https://github.com/yezhizhen&quot;&gt;@yezhizhen&lt;/a&gt;, &lt;a href=&quot;https://github.com/longvatrong111&quot;&gt;@longvatrong111&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37546&quot;&gt;#37546&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37578&quot;&gt;#37578&lt;/a&gt;, &lt;a href=&quot;https://github.com/servo/servo/pull/37280&quot;&gt;#37280&lt;/a&gt;).&lt;/p&gt;

  8878. <title>Mozilla GFX: Shipping WebGPU on Windows in Firefox 141</title>
  8879. <guid isPermaLink="false">http://mozillagfx.wordpress.com/?p=1424</guid>
  8880. <link>https://mozillagfx.wordpress.com/2025/07/15/shipping-webgpu-on-windows-in-firefox-141/</link>
  8881. <description>&lt;p&gt;After years in development, we will be releasing WebGPU on Windows in Firefox 141! WebGPU gives web content a modern interface to the user’s graphics processor, enabling high-performance computation and rendering. We’re excited about WebGPU because we believe it will raise the ceiling for games, visualization, and local computation on the web.&lt;/p&gt;
  8882.  
  8883.  
  8884.  
  8885. &lt;p&gt;You can find a tutorial on WebGPU at &lt;a href=&quot;https://webgpufundamentals.org/&quot;&gt;webgpufundamentals.org&lt;/a&gt;, try out the &lt;a href=&quot;https://webgpu.github.io/webgpu-samples/&quot;&gt;WebGPU Samples&lt;/a&gt;, and read documentation for the API at &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/WebGPU_API&quot;&gt;MDN&lt;/a&gt;. WebGPU is defined in two W3C standards, &lt;a href=&quot;https://www.w3.org/TR/webgpu/&quot;&gt;WebGPU&lt;/a&gt; and &lt;a href=&quot;https://www.w3.org/TR/WGSL/&quot;&gt;WGSL&lt;/a&gt;, whose development Mozilla has participated in since it began in 2017.&lt;/p&gt;
  8886.  
  8887.  
  8888.  
  8889. &lt;p&gt;WebGPU has been available in Google Chrome since 2023, and is expected to be available in Safari 26 this fall.&lt;/p&gt;
  8890.  
  8891.  
  8892.  
  8893. &lt;p&gt;Although Firefox 141 enables WebGPU only on Windows, we plan to ship WebGPU on Mac and Linux in the coming months, and finally on Android. Windows was our first priority because that’s where the great majority of our users are, but we are looking forward to enabling it on the other platforms as soon as it is robust and our test coverage is adequate. (Your humble author is strictly a Linux user, so this concern is close to his heart.) Note that WebGPU has been available in Firefox Nightly on all platforms other than Android for quite some time.&lt;/p&gt;
  8894.  
  8895.  
  8896.  
  8897. &lt;p&gt;Firefox’s WebGPU implementation is based on &lt;a href=&quot;https://github.com/gfx-rs/wgpu&quot;&gt;WGPU&lt;/a&gt;, a Rust crate that provides a unified, portable interface to the low-level graphics APIs of the underlying platform: &lt;a href=&quot;https://learn.microsoft.com/en-us/windows/win32/direct3d12/what-is-directx-12-&quot;&gt;Direct3D 12&lt;/a&gt;, &lt;a href=&quot;https://developer.apple.com/metal/&quot;&gt;Metal&lt;/a&gt;, and &lt;a href=&quot;https://www.vulkan.org/&quot;&gt;Vulkan&lt;/a&gt;. WGPU is developed as an independent open source project on GitHub, but Mozilla is a major contributor. WGPU is widely used outside Firefox, and has an active community, so if you are a Rust developer interested in contributing to Firefox’s WebGPU support, WGPU is a good place to start.&lt;/p&gt;
  8898.  
  8899.  
  8900.  
  8901. &lt;p&gt;WebGPU is a large, complex API. We’ve focused our efforts so far on making high-visibility WebGPU applications and demos run smoothly, and we believe it should work well in Firefox 141 for many use cases. However, there is plenty of work remaining to be done to improve our performance and compliance with the specification. In particular:&lt;/p&gt;
  8902.  
  8903.  
  8904.  
  8905. &lt;ul class=&quot;wp-block-list&quot;&gt;
  8906. &lt;li&gt;Firefox uses unbuffered inter-process communication to convey web content’s requests to the GPU sandbox process, which introduces significant overhead. We addressed this in &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1968122&quot;&gt;Bug 1968122&lt;/a&gt;, which improved performance significantly. The fix will appear in Firefox 142.&lt;/li&gt;
  8907.  
  8908.  
  8909.  
  8910. &lt;li&gt;Firefox currently uses an interval timer to tell when the GPU has completed a task, adding significant latency to many applications where the task finishes quickly. There are better ways to do this, we are changing Firefox to use them. You can follow our progress in &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1870699&quot;&gt;Bug 1870699&lt;/a&gt;.&lt;/li&gt;
  8911.  
  8912.  
  8913.  
  8914. &lt;li&gt;Firefox does not yet support WebGPU’s &lt;a href=&quot;https://www.w3.org/TR/webgpu/#dom-gpudevice-importexternaltexture&quot;&gt;importExternalTexture&lt;/a&gt; method, which lets the GPU read decompressed video content directly from the decoder. You can follow our progress in &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1827116&quot;&gt;Bug 1827116&lt;/a&gt;.&lt;/li&gt;
  8915. &lt;/ul&gt;
  8916.  
  8917.  
  8918.  
  8919. &lt;p&gt;Please give WebGPU a try in Firefox! If you encounter problems, please report them in the &lt;a href=&quot;https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&amp;amp;component=Graphics%3A%20WebGPU&quot;&gt;WebGPU component&lt;/a&gt; in Bugzilla. As always, provide us with as detailed instructions as you can to make the bug occur, and attach the contents of &lt;a href=&quot;https://mozillagfx.wordpress.com/feed/support&quot;&gt;about:support&lt;/a&gt; to the bug so we can see what kind of system you are using.&lt;/p&gt;
  8920.  
  8921.  
  8922.  
  8923. &lt;p&gt;It’s been a big project, but we’re done tinkering with the engine and taking test drives — we’re finally ready to roll WebGPU out of the garage and hand it over to you for daily use. We’re looking forward to seeing what you can do with WebGPU in Firefox!&lt;/p&gt;</description>

  8931. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/blog-banner-mobile-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  8932. &lt;p&gt;Welcome back to another update on how things are going on mobile. &lt;/p&gt;
  8933.  
  8934.  
  8935.  
  8936. &lt;h3&gt;Thunderbird for iOS&lt;/h3&gt;
  8937.  
  8938.  
  8939.  
  8940. &lt;p&gt;We’ve been going back and forth between database and JMAP for Thunderbird for iOS. Most of the visible work has flown into creating an initial JMAP library that we can use to access the parts that we need from Thunderbird for iOS. This work will continue into July as well. Progress so far means making JSON requests and parsing responses and making standard get/set/query requests. There is support for working with sessions as well.&lt;/p&gt;
  8941.  
  8942.  
  8943.  
  8944. &lt;p&gt;In July we’ll have a few things to show for viewing actual folders and email messages. Very preliminary, but already quite some progress! I’m almost tempted to post the screenshots now but I’ll wait until next month. We’ll also be releasing a new (currently still internal) Testflight version when everything has landed.&lt;/p&gt;
  8945.  
  8946.  
  8947.  
  8948. &lt;h3&gt;Thunderbird for Android&lt;/h3&gt;
  8949.  
  8950.  
  8951.  
  8952. &lt;p&gt;We want to make Thunderbird for Android more accessible to contributors and improve some of our documentation. Part of that is our brand new &lt;a href=&quot;https://thunderbird.github.io/thunderbird-android/docs/latest/contributing/testing-guide.html&quot;&gt;testing guide&lt;/a&gt; which talks about which testing patterns to use, how to adhere to our naming conventions and some guidelines around fakes vs mocks. We’ve recently been talking about making more use of the &lt;a href=&quot;https://maestro.dev/&quot;&gt;Maestro&lt;/a&gt; testing framework, as it makes it very simple to add tests even for folks without engineering experience. &lt;/p&gt;
  8953.  
  8954.  
  8955.  
  8956. &lt;p&gt;Further we’ve made some strides on our &lt;a href=&quot;https://thunderbird.github.io/thunderbird-android/docs/latest/architecture/index.html&quot;&gt;overall architecture documentation&lt;/a&gt;. If you’ve been reluctant to contribute because of the learning curve, this might be your chance to make another attempt. Even if you are an existing contributor, we believe the docs will help you understand the codebase a bit better. Let us know what you think, if you see a way that our documentation can be improved go ahead and file an issue.&lt;/p&gt;
  8957.  
  8958.  
  8959.  
  8960. &lt;p&gt;Next up, we’re nearing the end of the drawer updates we’ve been working on. We know a bunch of folks weren’t very happy with the navigation rail given the extra horizontal space it uses, and it being unclear which account you actually have selected. We’re returning the account selector to the top, and sporting a separate “Unified Account” where you can find not just your unified inbox, but also some other unified folders. If you’ve set up custom unified folders previously these will appear there as well. &lt;/p&gt;
  8961.  
  8962.  
  8963.  
  8964. &lt;figure class=&quot;wp-block-image size-full&quot;&gt;&lt;a href=&quot;https://blog.thunderbird.net/files/2025/07/JuneMobileUpdate.png&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;wp-image-3598&quot; height=&quot;647&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/JuneMobileUpdate.png&quot; width=&quot;1600&quot; /&gt;&lt;/a&gt;&lt;/figure&gt;
  8965.  
  8966.  
  8967.  
  8968. &lt;h3&gt;Additional updates&lt;/h3&gt;
  8969.  
  8970.  
  8971.  
  8972. &lt;ul&gt;
  8973. &lt;li&gt;&lt;a href=&quot;https://github.com/asoucar&quot;&gt;Ashley&lt;/a&gt; has worked on &lt;a href=&quot;https://github.com/thunderbird/thunderbird-android/issues/8836&quot;&gt;sync debug tooling&lt;/a&gt; so we can get a better understanding of any issues related to emails not arriving in time.&lt;/li&gt;
  8974.  
  8975.  
  8976.  
  8977. &lt;li&gt;&lt;a href=&quot;https://github.com/yantarou&quot;&gt;Jan&lt;/a&gt; has switched the EHLO string from 127.0.0.1 to &lt;a href=&quot;http://ehlo.thunderbird.net&quot;&gt;ehlo.thunderbird.net&lt;/a&gt; to increase compatibility with email servers that don’t accept 127.0.0.1.&lt;/li&gt;
  8978.  
  8979.  
  8980.  
  8981. &lt;li&gt;&lt;a href=&quot;https://github.com/joohnq&quot;&gt;João&lt;/a&gt; has improved accessibility of the contact pictures in the message view, and fixed an issue where the “Download Complete Message” button was hidden by the navigation bar.&lt;/li&gt;
  8982.  
  8983.  
  8984.  
  8985. &lt;li&gt;&lt;a href=&quot;https://github.com/rafaeltonholo&quot;&gt;Rafael&lt;/a&gt; has been working on the foundations of &lt;a href=&quot;https://github.com/thunderbird/thunderbird-android/issues/8831&quot;&gt;in-app error notifications&lt;/a&gt;. He improved swiping actions for when the account does not have an archive folder set, to avoid surprises. Through this work a bunch of files have been migrated from Java to Kotlin, great work!&lt;/li&gt;
  8986.  
  8987.  
  8988.  
  8989. &lt;li&gt;&lt;a href=&quot;https://github.com/skeller&quot;&gt;Stefan&lt;/a&gt; has fixed an issue where some I/O errors were not correctly caught. I’m particularly excited about this since it smooths over the situation where you change from one network to the next, so that push email will arrive a little more reliably.&lt;/li&gt;
  8990.  
  8991.  
  8992.  
  8993. &lt;li&gt;&lt;a href=&quot;http://github.com/wmontwe&quot;&gt;Wolf&lt;/a&gt; has revamped some of our internal logging support to be more consistent. We really don’t need multiple different loggers and might want to change the implementation once in a while &lt;img alt=&quot;🙂&quot; class=&quot;wp-smiley&quot; src=&quot;https://s.w.org/images/core/emoji/14.0.0/72x72/1f642.png&quot; style=&quot;height: 1em;&quot; /&gt; There has also been a bunch of Java/Kotlin conversion going on, and some refactoring in the local search code. Above mentioned work on the drawer and documentation was also Wolf’s work. &lt;/li&gt;
  8994.  
  8995.  
  8996.  
  8997. &lt;li&gt;&lt;a href=&quot;https://github.com/shamim-emon&quot;&gt;Shamim&lt;/a&gt; continues to rock the refactoring. By far the most Java to Kotlin conversion, fixing a crash when adding an account after removal, making threaded view update correctly when in the message list. Notably, the [Gmail] folder placeholder is now no longer visible, you’ll see the subfolders directly.&lt;/li&gt;
  8998. &lt;/ul&gt;

  9008. <title>The Rust Programming Language Blog: crates.io: development update</title>
  9009. <guid isPermaLink="true">https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/</guid>
  9010. <link>https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/</link>
  9011. <description>&lt;p&gt;Since our last development update in &lt;a href=&quot;https://blog.rust-lang.org/2025/02/05/crates-io-development-update.html&quot;&gt;February 2025&lt;/a&gt;, we have continued to make significant improvements to &lt;a href=&quot;https://crates.io/&quot;&gt;crates.io&lt;/a&gt;. In this blog post, we want to give you an update on the latest changes that we have made to crates.io over the past few months.&lt;/p&gt;
  9012. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#trusted-publishing&quot;&gt;&lt;/a&gt;
  9013. Trusted Publishing&lt;/h3&gt;
  9014. &lt;p&gt;We are excited to announce that we have implemented &quot;Trusted Publishing&quot; support on crates.io, as described in &lt;a href=&quot;https://rust-lang.github.io/rfcs/3691-trusted-publishing-cratesio.html&quot;&gt;RFC #3691&lt;/a&gt;. This feature was inspired by the PyPI team's excellent work in this area, and we want to thank them for the inspiration!&lt;/p&gt;
  9015. &lt;p&gt;Trusted Publishing eliminates the need for GitHub Actions secrets when publishing crates from your CI/CD pipeline. Instead of managing API tokens, you can now configure which GitHub repository you trust directly on crates.io. That repository is then allowed to request a short-lived API token for publishing in a secure way using OpenID Connect (OIDC). While Trusted Publishing is currently limited to GitHub Actions, we have built it in a way that allows other CI/CD providers like GitLab CI to be supported in the future.&lt;/p&gt;
  9016. &lt;p&gt;To get started with Trusted Publishing, you'll need to publish your first release manually. After that, you can set up trusted publishing for future releases. The detailed documentation is available at &lt;a href=&quot;https://crates.io/docs/trusted-publishing&quot;&gt;https://crates.io/docs/trusted-publishing&lt;/a&gt;.&lt;/p&gt;
  9017. &lt;p&gt;&lt;img alt=&quot;Trusted Publishers Settings&quot; src=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/trustpub-settings.png&quot; /&gt;&lt;/p&gt;
  9018. &lt;p&gt;Here's an example of how to set up GitHub Actions to use Trusted Publishing:&lt;/p&gt;
  9019. &lt;pre class=&quot;language-yaml z-code&quot;&gt;&lt;code class=&quot;language-yaml&quot;&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;&lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;&lt;span class=&quot;z-entity z-name z-tag z-yaml&quot;&gt;name&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-key-value z-mapping z-yaml&quot;&gt;:&lt;/span&gt; &lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;Publish to crates.io&lt;/span&gt;
  9020. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;
  9021. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;&lt;span class=&quot;z-constant z-language z-boolean z-yaml&quot;&gt;on&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-key-value z-mapping z-yaml&quot;&gt;:&lt;/span&gt;

  9023. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;    &lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;&lt;span class=&quot;z-entity z-name z-tag z-yaml&quot;&gt;tags&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-key-value z-mapping z-yaml&quot;&gt;:&lt;/span&gt; &lt;span class=&quot;z-meta z-flow-sequence z-yaml&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-sequence z-begin z-yaml&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;z-string z-quoted z-single z-yaml&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-string z-begin z-yaml&quot;&gt;'&lt;/span&gt;v*&lt;span class=&quot;z-punctuation z-definition z-string z-end z-yaml&quot;&gt;'&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-definition z-sequence z-end z-yaml&quot;&gt;]&lt;/span&gt;&lt;/span&gt;  &lt;span class=&quot;z-comment z-line z-number-sign z-yaml&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-comment z-line z-number-sign z-yaml&quot;&gt;#&lt;/span&gt; Triggers when pushing tags starting with 'v'
  9024. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;
  9025. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;&lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;&lt;span class=&quot;z-entity z-name z-tag z-yaml&quot;&gt;jobs&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-key-value z-mapping z-yaml&quot;&gt;:&lt;/span&gt;

  9027. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;    &lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;&lt;span class=&quot;z-entity z-name z-tag z-yaml&quot;&gt;runs-on&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-key-value z-mapping z-yaml&quot;&gt;:&lt;/span&gt; &lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;ubuntu-latest&lt;/span&gt;
  9028. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;
  9029. &lt;/span&gt;&lt;span class=&quot;z-source z-yaml&quot;&gt;    &lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;&lt;span class=&quot;z-entity z-name z-tag z-yaml&quot;&gt;environment&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-separator z-key-value z-mapping z-yaml&quot;&gt;:&lt;/span&gt; &lt;span class=&quot;z-string z-unquoted z-plain z-out z-yaml&quot;&gt;release&lt;/span&gt;  &lt;span class=&quot;z-comment z-line z-number-sign z-yaml&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-comment z-line z-number-sign z-yaml&quot;&gt;#&lt;/span&gt; Optional: for enhanced security

  9040. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  9041. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#opengraph-images&quot;&gt;&lt;/a&gt;
  9042. OpenGraph Images&lt;/h3&gt;
  9043. &lt;p&gt;Previously, crates.io used a single OpenGraph image for all pages. We have now implemented dynamic OpenGraph image generation, where each crate has a dedicated image that is regenerated when new versions are published.&lt;/p&gt;
  9044. &lt;p&gt;These images include the crate name, keywords, description, latest version (or rather the default version that we show for the crate), number of releases, license, and crate size. This provides much more useful information when crates.io links are shared on social media platforms or in chat applications.&lt;/p&gt;
  9045. &lt;p&gt;&lt;img alt=&quot;OpenGraph Image for the bon crate&quot; src=&quot;https://static.crates.io/og-images/bon.png&quot; /&gt;&lt;/p&gt;
  9046. &lt;p&gt;The image generation has been extracted to a dedicated crate: &lt;a href=&quot;https://crates.io/crates/crates_io_og_image&quot;&gt;crates_io_og_image&lt;/a&gt; (&lt;a href=&quot;https://github.com/rust-lang/crates_io_og_image&quot;&gt;GitHub&lt;/a&gt;). We're also adding basic theming support in &lt;a href=&quot;https://github.com/rust-lang/crates_io_og_image/pull/3&quot;&gt;PR #3&lt;/a&gt; to allow docs.rs to reuse the code for their own OpenGraph images.&lt;/p&gt;
  9047. &lt;p&gt;Under the hood, the image generation uses two other excellent Rust projects: &lt;a href=&quot;https://typst.app/&quot;&gt;Typst&lt;/a&gt; for layout and text rendering, and &lt;a href=&quot;https://github.com/oxipng/oxipng&quot;&gt;oxipng&lt;/a&gt; for PNG optimization.&lt;/p&gt;
  9048. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#docs-rs-rebuilds&quot;&gt;&lt;/a&gt;
  9049. docs.rs rebuilds&lt;/h3&gt;
  9050. &lt;p&gt;Crate owners can now trigger documentation rebuilds for docs.rs directly from the crate's version list on crates.io. This can be useful when docs.rs builds have failed or when you want to take advantage of new docs.rs features without having to publish a new release just for that.&lt;/p&gt;
  9051. &lt;p&gt;&lt;img alt=&quot;docs.rs Rebuild Confirmation&quot; src=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/docs-rebuild-confirmation.png&quot; /&gt;&lt;/p&gt;
  9052. &lt;p&gt;We would like to thank our crates.io team member &lt;a href=&quot;https://github.com/eth3lbert&quot;&gt;@eth3lbert&lt;/a&gt; for implementing the initial version of this feature in &lt;a href=&quot;https://github.com/rust-lang/crates.io/pull/11422&quot;&gt;PR #11422&lt;/a&gt;.&lt;/p&gt;
  9053. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#readme-alert-support&quot;&gt;&lt;/a&gt;
  9054. README alert support&lt;/h3&gt;
  9055. &lt;p&gt;We've added support for rendering GitHub-style alerts in README files. This feature allows crate authors to use alert blocks like &lt;code&gt;&amp;gt; [!NOTE]&lt;/code&gt;, &lt;code&gt;&amp;gt; [!WARNING]&lt;/code&gt;, and &lt;code&gt;&amp;gt; [!CAUTION]&lt;/code&gt; in their README markdown, which will now be properly styled and displayed on crates.io.&lt;/p&gt;
  9056. &lt;p&gt;&lt;img alt=&quot;README alerts example&quot; src=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/readme-alerts.png&quot; /&gt;&lt;/p&gt;
  9057. &lt;p&gt;This enhancement was also implemented by &lt;a href=&quot;https://github.com/eth3lbert&quot;&gt;@eth3lbert&lt;/a&gt; in &lt;a href=&quot;https://github.com/rust-lang/crates.io/pull/11441&quot;&gt;PR #11441&lt;/a&gt;, building on initial work by &lt;a href=&quot;https://github.com/kbdharun&quot;&gt;@kbdharun&lt;/a&gt;.&lt;/p&gt;
  9058. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#miscellaneous&quot;&gt;&lt;/a&gt;
  9059. Miscellaneous&lt;/h3&gt;
  9060. &lt;p&gt;These were some of the more visible changes to crates.io over the past couple of months, but a lot has happened &quot;under the hood&quot; as well. Here are a couple of examples:&lt;/p&gt;
  9061. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#email-system-refactoring&quot;&gt;&lt;/a&gt;
  9062. Email system refactoring&lt;/h4&gt;
  9063. &lt;p&gt;Previously, we used the &lt;code&gt;format!()&lt;/code&gt; macro and string concatenation to create emails, which made them hard to maintain and inconsistent in styling. We have migrated to the &lt;a href=&quot;https://github.com/mitsuhiko/minijinja&quot;&gt;minijinja&lt;/a&gt; crate and now use templates instead.&lt;/p&gt;
  9064. &lt;p&gt;The new system includes a template inheritance system for consistent branding across all emails. This change also enables us to support HTML emails in the future.&lt;/p&gt;
  9065. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#semver-sorting-optimization&quot;&gt;&lt;/a&gt;
  9066. SemVer sorting optimization&lt;/h4&gt;
  9067. &lt;p&gt;Previously, we had to load all versions from the database and sort them by &lt;a href=&quot;https://semver.org/&quot;&gt;SemVer&lt;/a&gt; on the API server, which was inefficient for crates with many versions. Our PostgreSQL provider did not support the &lt;a href=&quot;https://pgxn.org/dist/semver/&quot;&gt;semver extension&lt;/a&gt;, so we had to implement sorting in application code.&lt;/p&gt;
  9068. &lt;p&gt;&lt;a href=&quot;https://github.com/rust-lang/crates.io/pull/10763&quot;&gt;PR #10763&lt;/a&gt; takes advantage of JSONB support in PostgreSQL and their btree ordering specification to implement SemVer sorting on the database side. This reduces the load on our API servers and improves response times for crates with many versions.&lt;/p&gt;
  9069. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/11/crates-io-development-update-2025-07/#feedback&quot;&gt;&lt;/a&gt;
  9070. Feedback&lt;/h3&gt;
  9071. &lt;p&gt;We hope you enjoyed this update on the development of crates.io. If you have any feedback or questions, please let us know on &lt;a href=&quot;https://rust-lang.zulipchat.com/#narrow/stream/318791-t-crates-io&quot;&gt;Zulip&lt;/a&gt; or &lt;a href=&quot;https://github.com/rust-lang/crates.io/discussions&quot;&gt;GitHub&lt;/a&gt;.

  9076. <title>Mozilla Thunderbird: Thunderbird Monthly Development Digest – June 2025</title>
  9077. <guid isPermaLink="false">https://blog.thunderbird.net/?p=3588</guid>
  9078. <link>https://blog.thunderbird.net/2025/07/thunderbird-monthly-development-digest-june-2025/</link>
  9079. <description>&lt;p&gt;&lt;img alt=&quot;&quot; class=&quot;attachment-640x360 size-640x360 wp-post-image&quot; height=&quot;360&quot; src=&quot;https://blog.thunderbird.net/files/2025/07/blog-banner-developer-FINAL5-768x432.jpg&quot; width=&quot;640&quot; /&gt;&lt;/p&gt;
  9080. &lt;p&gt;Hello once more from the Thunderbird development team! For many of our team members, the summer has started with our annual sprint to release ESR and enjoy a little time afk, as our colleagues in the southern hemisphere hunker down for winter and power through a pile of work down under.&lt;/p&gt;
  9081.  
  9082.  
  9083.  
  9084. &lt;h4&gt;&lt;strong&gt;Extended Support Release is alive!&lt;/strong&gt;&lt;/h4&gt;
  9085.  
  9086.  
  9087.  
  9088. &lt;p&gt;For enterprise users (and those who have been using Thunderbird for a long time and found themselves on the Extended Support Release channel), the annual release “ESR 140 Eclipse” has made it to our update servers and will be pushed out over the next few weeks. &lt;/p&gt;
  9089.  
  9090.  
  9091.  
  9092. &lt;p&gt;We had initially planned to release within hours or days of the Firefox ESR release, but much of the ESR build process has changed in the last 12 months (largely due to the Firefox mozilla-central Git migration) – so we ended up learning a lot and took pause to release at a time that produced the best experience for the majority of our users. &lt;/p&gt;
  9093.  
  9094.  
  9095.  
  9096. &lt;p&gt;In the hours following the initial release, we have another build hot on its heels which includes some important patches and will ship today or tomorrow. Things move fast around here!&lt;/p&gt;
  9097.  
  9098.  
  9099.  
  9100. &lt;p&gt;If waiting a year doesn’t sound appealing to you, our Monthly release may be better suited. It offers access to the latest features, improvements, and fixes as soon as they’re ready. Watch out for an in-app invitation to upgrade or &lt;a href=&quot;https://blog.thunderbird.net/2025/03/thunderbird-release-channel-update/&quot;&gt;&lt;u&gt;install over ESR to retain your profile settings.&lt;/u&gt;&lt;/a&gt;&lt;/p&gt;
  9101.  
  9102.  
  9103.  
  9104. &lt;h4&gt;&lt;strong&gt;Exchange support in Daily&lt;/strong&gt;&lt;/h4&gt;
  9105.  
  9106.  
  9107.  
  9108. &lt;p&gt;The EWS 0.2 milestone has been completed and the feature was turned on by default in Daily release to facilitate more manual QA testing. In order to provide test coverage on a variety of EWS server versions and configurations, we’re tackling in a few ways:&lt;/p&gt;
  9109.  
  9110.  
  9111.  
  9112. &lt;ul&gt;
  9113. &lt;li&gt;Adding a small number of Hosted Exchange 2016 mailboxes to facilitate testing of all existing functionality at endpoints other than O365.&lt;/li&gt;
  9114.  
  9115.  
  9116.  
  9117. &lt;li&gt;Contacting enterprise partners who can help us test on their infrastructure – please get in touch if this might be you!&lt;/li&gt;
  9118.  
  9119.  
  9120.  
  9121. &lt;li&gt;Hosting our own EWS instance that allows us to configure a variety of security and authentication settings to ensure our code works for all&lt;/li&gt;
  9122.  
  9123.  
  9124.  
  9125. &lt;li&gt;Focusing on automated test coverage throughout the month of July&lt;/li&gt;
  9126. &lt;/ul&gt;
  9127.  
  9128.  
  9129.  
  9130. &lt;p&gt;Since my last update, the team has grown even more and made great progress on items in our “Phase 2 operations” and “Phase 2 polish” milestones, with these features delivered recently:&lt;/p&gt;
  9131.  
  9132.  
  9133.  
  9134. &lt;ul&gt;
  9135. &lt;li&gt;EWS-to-EWS move &amp;amp; copy for items and folders&lt;/li&gt;
  9136.  
  9137.  
  9138.  
  9139. &lt;li&gt;Authentication Error handling&lt;/li&gt;
  9140.  
  9141.  
  9142.  
  9143. &lt;li&gt;Server Version handling&lt;/li&gt;
  9144.  
  9145.  
  9146.  
  9147. &lt;li&gt;Threading support&lt;/li&gt;
  9148.  
  9149.  
  9150.  
  9151. &lt;li&gt;Folder updates &amp;amp; deletions during sync operations&lt;/li&gt;
  9152.  
  9153.  
  9154.  
  9155. &lt;li&gt;Folder cache cleanup&lt;/li&gt;
  9156.  
  9157.  
  9158.  
  9159. &lt;li&gt;Folder copy/move&lt;/li&gt;
  9160.  
  9161.  
  9162.  
  9163. &lt;li&gt;Bug fixes!&lt;/li&gt;
  9164. &lt;/ul&gt;
  9165.  
  9166.  
  9167.  
  9168. &lt;p&gt;We plan to temporarily expand the team during July to include two more of our most experienced senior engineers to push this project over the finish line and tackle some remaining complexities:&lt;/p&gt;
  9169.  
  9170.  
  9171.  
  9172. &lt;ul&gt;
  9173. &lt;li&gt;Automated test coverage&lt;/li&gt;
  9174.  
  9175.  
  9176.  
  9177. &lt;li&gt;Message filtering&lt;/li&gt;
  9178.  
  9179.  
  9180.  
  9181. &lt;li&gt;Setting as Junk/Not Junk&lt;/li&gt;
  9182.  
  9183.  
  9184.  
  9185. &lt;li&gt;Bug backlog&lt;/li&gt;
  9186. &lt;/ul&gt;
  9187.  
  9188.  
  9189.  
  9190. &lt;p&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1847846&quot;&gt;&lt;u&gt;Keep track of feature delivery here.&lt;/u&gt;&lt;/a&gt;&lt;/p&gt;
  9191.  
  9192.  
  9193.  
  9194. &lt;h4&gt;&lt;strong&gt;Account Hub&lt;/strong&gt;&lt;/h4&gt;
  9195.  
  9196.  
  9197.  
  9198. &lt;p&gt;The new email account feature was enabled as the default experience for users adding their second email account. It is now available in all release channels. We’re currently finalizing the UX and associated functionality that detects whether account autodiscovery requires a password, and reacts accordingly – which will hopefully be uplifted once stable.&lt;/p&gt;
  9199.  
  9200.  
  9201.  
  9202. &lt;p&gt;We’re wrapping up the redesigned Account Hub UI for Address Book account additions this week, which we’ll enable for users on Daily and beta in the coming weeks. Look out for it in our Monthly release 142.&lt;/p&gt;
  9203.  
  9204.  
  9205.  
  9206. &lt;h4&gt;&lt;strong&gt;Global Message Database&lt;/strong&gt;&lt;/h4&gt;
  9207.  
  9208.  
  9209.  
  9210. &lt;p&gt;Since the last update, we’ve landed a landslide of patches. Critical refactoring continues to clean and optimize the code, in many cases clearing the way for new beneficial protocol implementations.&lt;/p&gt;
  9211.  
  9212.  
  9213.  
  9214. &lt;p&gt;To follow their progress, take a look at the &lt;a href=&quot;https://bugzilla.mozilla.org/showdependencytree.cgi?id=1572000&amp;amp;hide_resolved=1&quot;&gt;&lt;u&gt;meta bug dependency tree&lt;/u&gt;&lt;/a&gt;. The team also maintains documentation in Sourcedocs which are visible &lt;a href=&quot;https://source-docs.thunderbird.net/en/latest/panorama/index.html&quot;&gt;&lt;u&gt;here&lt;/u&gt;&lt;/a&gt;.&lt;/p&gt;
  9215.  
  9216.  
  9217.  
  9218. &lt;h4&gt;&lt;strong&gt;Recent Features and Fixes&lt;/strong&gt;&lt;/h4&gt;
  9219.  
  9220.  
  9221.  
  9222. &lt;p&gt;A number of other features and fixes have reached our Daily users this month. We want to give special thanks to the contributors who made the following possible…&lt;/p&gt;
  9223.

  9266. <title>Support.Mozilla.Org: What’s up with SUMO – H1 2025</title>
  9267. <guid isPermaLink="false">https://blog.mozilla.org/sumo/?p=4182</guid>
  9268. <link>https://blog.mozilla.org/sumo/2025/07/09/whats-up-with-sumo-h1-2025/</link>
  9269. <description>&lt;p&gt;Hi everybody,&lt;/p&gt;
  9270. &lt;p&gt;It’s been a long overdue since our last update. Previously, we shared these recaps on a quarterly basis, but this time, we’re trying out a slightly new format and cadence to keep things fresh and more in tune with what’s happening across the community.&lt;/p&gt;
  9271. &lt;p&gt;In this post, we also include a broader set of data to give a clearer picture of how the community performed in H1 2025. We hope it helps highlight both what’s working well and where we have room for improvements.&lt;/p&gt;
  9272. &lt;p&gt;Without further ado, let’s dive in!&lt;/p&gt;
  9273. &lt;h3&gt;Highlights&lt;/h3&gt;
  9274. &lt;ul&gt;
  9275. &lt;li&gt;We started the year strong with the &lt;a href=&quot;https://community.mozilla.org/en/campaigns/test-the-new-firefox-address-bar/&quot;&gt;Firefox Address Bar Test Day Event&lt;/a&gt; in January 2025, which was a great success. By the end of the campaign, 40% of the average Daily Active Users who tried the feature completed the survey, which is an impressive response rate. The feedback collected gave the product team valuable insights to help refine the feature ahead of a broader launch.&lt;/li&gt;
  9276. &lt;li&gt;In early February, a few of us were headed to Brussels for &lt;a href=&quot;https://blog.mozilla.org/community/2025/02/06/fosdem-2025-a-celebration-of-open-source-innovation/&quot;&gt;FOSDEM 2025&lt;/a&gt;. It was truly wonderful to finally be able to connect face to face again.&lt;/li&gt;
  9277. &lt;li&gt;In May 2025, we made the difficult decision to &lt;a href=&quot;https://blog.mozilla.org/sumo/2025/05/30/decommissioning-of-the-social-support-and-mobile-store-support-programs/&quot;&gt;shut down the Social Support and Mobile Store Support&lt;/a&gt; to focus more on the &lt;a href=&quot;https://support.mozilla.org/questions/all&quot;&gt;Community Forums&lt;/a&gt;. This wasn’t a decision made lightly. We deeply appreciate the incredible dedication, time, and care that so many of you have invested in these programs over the years. We’re truly grateful for everything you’ve done to support users and represent Mozilla in these spaces that have made users feel heard, supported, and connected to our mission.&lt;/li&gt;
  9278. &lt;li&gt;We released the automatic spam moderation and topic classification to reduce moderation workload in early June. Posts that are clearly spam are now automatically marked as spam. By the end of June, we found that 87.85% of questions marked as spam automatically by this automation. This has significantly reduced the moderation workload previously handled by forum moderators, support agents, and CMs. We also noticed that the average spam rate per ISO week has increased to 40% in June (compared to 19% in the previous period), which may suggest that spam was previously under-reported. Huge kudos to the team who worked on this project. We can’t wait to learn more about what else we can do with this technology.&lt;/li&gt;
  9279. &lt;li&gt;Mozilla’s staff in the Customer Experience (CX) team went through several structural changes this year, with the departure of several members. Make sure to check out the &lt;a href=&quot;https://support.mozilla.org/kb/meet-team&quot;&gt;Meet the Team&lt;/a&gt; page to see the most up-to-date team structure.&lt;/li&gt;
  9280. &lt;/ul&gt;
  9281. &lt;h3&gt;Community stats&lt;/h3&gt;
  9282. &lt;h4&gt;Knowledge Base&lt;/h4&gt;
  9283. &lt;p&gt;In the Knowledge Base (KB) space, we saw a moderate increase in activity, with total revisions up by almost 5% and total articles growing by around 14%. Notably, the number of contributors rose to 105 (+14%), and reviewer participation increase&lt;/p&gt;
  9284. &lt;p&gt;&lt;b&gt;General stats&lt;/b&gt;&lt;/p&gt;
  9285. &lt;table style=&quot;height: 343px;&quot; width=&quot;555&quot;&gt;
  9286. &lt;tbody&gt;
  9287. &lt;tr&gt;
  9288. &lt;td&gt;Total en-US revisions&lt;/td&gt;
  9289. &lt;td&gt;731&lt;/td&gt;
  9290. &lt;td&gt;+4.9%&lt;/td&gt;
  9291. &lt;/tr&gt;
  9292. &lt;tr&gt;
  9293. &lt;td&gt;Total articles&lt;/td&gt;
  9294. &lt;td&gt;226&lt;/td&gt;
  9295. &lt;td&gt;+14.1%&lt;/td&gt;
  9296. &lt;/tr&gt;

  9707. <title>David Teller: (Quite) A Few Words About Async</title>

  9709. <link>https://yoric.github.io/post/quite-a-few-words-about-async/</link>
  9710. <description>&lt;p&gt;I’ve had a few conversations about async code recently (and not so
  9711. recently) and seen some code that seems to make wrong assumptions
  9712. about async, so I figured out it was time to have a serious chat
  9713. about async, what it’s for, what it guarantees and what it doesn’t.&lt;/p&gt;</description>

  9721. &lt;p&gt;The wait is over! Thunderbird 140 “Eclipse” has reached totality. From all of us at the Thunderbird project, from MZLA staff and the Thunderbird Council to our global community of contributors, we’re excited to announce the latest Extended Support Release has arrived.&lt;/p&gt;
  9722.  
  9723.  
  9724.  
  9725. &lt;p&gt;Eclipse not only builds on Thunderbird 128 “Nebula,” but also the recent features and improvements from the &lt;a href=&quot;https://updates.thunderbird.net/en-CA/thunderbird/128.0/monthly/?utm_campaign=esr140_announcement&amp;amp;utm_medium=web&amp;amp;utm_source=blog.thunderbird.net&quot;&gt;Monthly Release channel&lt;/a&gt;.

  9731.  
  9732.  
  9733.  
  9734. &lt;p&gt;Thunderbird’s Dark Mode now automatically adapts your messages when enabled, to ensure your Dark Mode experience stays totally dark. Need to bring your messages back into the light in case of visual problems? Adjust your message view as needed with a quick optional toggle.&lt;/p&gt;

  9806.  
  9807. &lt;h3&gt;&lt;strong&gt;Looking Forward&lt;/strong&gt;&lt;/h3&gt;
  9808.  
  9809.  
  9810.  
  9811. &lt;p&gt;Whether you’re waiting for the next Thunderbird ESR or total solar eclipse, we understand that sometimes you want new features, or that cosmic awe, sooner. While we can’t change the universe, you can now get the latest Thunderbird features as they land, instead of once a year. &lt;a href=&quot;https://updates.thunderbird.net/en-CA/thunderbird/128.0/monthly/?utm_campaign=esr140_announcement&amp;amp;utm_medium=web&amp;amp;utm_source=blog.thunderbird.net&quot;&gt;Switch to Thunderbird Release&lt;/a&gt; and enjoy monthly updates with the same dependable stability.&lt;/p&gt;
  9812.  
  9813.  
  9814.  
  9815. &lt;h3&gt;Thunderbird 140 Availability For Windows, Linux, and MacOS&lt;/h3&gt;
  9816.  
  9817.  
  9818.  
  9819. &lt;p&gt;Even with QA and beta testing, any major software release may have issues exposed after significant public testing. That’s why we are slowly enabling automatic updates until we’re confident no such issues exist. We do have a known issue where users sending mail through 32bit MAPI will be prompted for a password, unless they use the compose window.&lt;/p&gt;
  9820.  
  9821.  
  9822.  
  9823. &lt;p&gt;We have enabled manual upgrade to 140 via Help &amp;gt; About, and you can upgrade now or wait to receive automatic updates. Thunderbird version 140.0 is also offered as direct download from &lt;a href=&quot;https://thunderbird.net&quot;&gt;thunderbird.net&lt;/a&gt;. Be sure to select ‘Thunderbird Extended Support Release’ in the ‘Release Channel’ drop-down menu.&lt;/p&gt;
  9824.  
  9825.  
  9826.  
  9827. &lt;p&gt;For Linux users running Thunderbird from the snap or flatpak, 140 will be available within the next few weeks. Likewise, Thunderbird 140 will also arrive on the Windows store by mid-July. &lt;/p&gt;

  9836. <description>These recent blog posts are veering in the “here’s a horrible thing I just did!” direction. No apologies. Recently, I was working on a weird problem where I wanted to snapshot /proc/$pid/maps before and after a couple of mmap and madvise calls. But I didn’t particularly want to write C++ code to do it. So: […]</description>

  9844. <description>&lt;p&gt;Rust &lt;a href=&quot;https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/&quot;&gt;1.88.0&lt;/a&gt; stabilizes the &lt;code&gt;#[unsafe(naked)]&lt;/code&gt; attribute and the &lt;code&gt;naked_asm!&lt;/code&gt; macro which are used to define naked functions.&lt;/p&gt;
  9845. &lt;p&gt;A naked function is marked with the &lt;code&gt;#[unsafe(naked)]&lt;/code&gt; attribute, and its body consists of a single &lt;code&gt;naked_asm!&lt;/code&gt; call. For example:&lt;/p&gt;
  9846. &lt;pre class=&quot;language-rust z-code&quot;&gt;&lt;code class=&quot;language-rust&quot;&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;&lt;span class=&quot;z-comment z-line z-documentation z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-comment z-rust&quot;&gt;///&lt;/span&gt; SAFETY: Respects the 64-bit System-V ABI.

  9855. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  9856. &lt;p&gt;What makes naked functions special — and gives them their name — is that the handwritten assembly block defines the &lt;em&gt;entire&lt;/em&gt; function body. Unlike non-naked functions, the compiler does not add any special handling for arguments or return values.&lt;/p&gt;
  9857. &lt;p&gt;This feature is a more ergonomic alternative to defining functions using &lt;code&gt;global_asm!&lt;/code&gt;. Naked functions are used in low-level settings like Rust's &lt;a href=&quot;https://github.com/rust-lang/compiler-builtins&quot;&gt;&lt;code&gt;compiler-builtins&lt;/code&gt;&lt;/a&gt;, operating systems, and embedded applications.&lt;/p&gt;

  9859. Why use naked functions?&lt;/h3&gt;
  9860. &lt;p&gt;But wait, if naked functions are just syntactic sugar for &lt;code&gt;global_asm!&lt;/code&gt;, why add them in the first place?&lt;/p&gt;
  9861. &lt;p&gt;To see the benefits, let's rewrite the &lt;code&gt;wrapping_add&lt;/code&gt; example from the introduction using &lt;code&gt;global_asm!&lt;/code&gt;:&lt;/p&gt;

  9884. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  9885. &lt;p&gt;The assembly block starts and ends with the directives (&lt;code&gt;.section&lt;/code&gt;, &lt;code&gt;.p2align&lt;/code&gt;, etc.) that are required to define a function. These directives are mechanical, but they are different between object file formats. A naked function will automatically emit the right directives.&lt;/p&gt;
  9886. &lt;p&gt;Next, the &lt;code&gt;wrapping_add&lt;/code&gt; name is hardcoded, and will not participate in Rust's name mangling. That makes it harder to write cross-platform code, because different targets have different name mangling schemes (e.g. x86_64 macOS prefixes symbols with &lt;code&gt;_&lt;/code&gt;, but Linux does not). The unmangled symbol is also globally visible — so that the &lt;code&gt;extern&lt;/code&gt; block can find it — which can cause symbol resolution conflicts. A naked function's name does participate in name mangling and won't run into these issues.&lt;/p&gt;
  9887. &lt;p&gt;A further limitation that this example does not show is that functions defined using global assembly cannot use generics. Especially const generics are useful in combination with assembly.&lt;/p&gt;
  9888. &lt;p&gt;Finally, having just one definition provides a consistent place for (safety) documentation and attributes, with less risk of them getting out of date. Proper safety comments are essential for naked functions. The &lt;code&gt;naked&lt;/code&gt; attribute is unsafe because the ABI (&lt;code&gt;sysv64&lt;/code&gt; in our example), the signature, and the implementation have to be consistent.&lt;/p&gt;
  9889. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/03/stabilizing-naked-functions/#how-did-we-get-here&quot;&gt;&lt;/a&gt;
  9890. How did we get here?&lt;/h3&gt;
  9891. &lt;p&gt;Naked functions have been in the works for a long time.&lt;/p&gt;
  9892. &lt;p&gt;The &lt;a href=&quot;https://github.com/rust-lang/rfcs/pull/1201&quot;&gt;original RFC&lt;/a&gt; for naked functions is from 2015. That RFC was superseded by &lt;a href=&quot;https://github.com/rust-lang/rfcs/pull/2972&quot;&gt;RFC 2972&lt;/a&gt; in 2020. Inline assembly in Rust had changed substantially at that point, and the new RFC limited the body of naked functions to a single &lt;code&gt;asm!&lt;/code&gt; call with some additional constraints. And now, 10 years after the initial proposal, naked functions are stable.&lt;/p&gt;
  9893. &lt;p&gt;Two additional notable changes helped prepare naked functions for stabilization:&lt;/p&gt;
  9894. &lt;h6&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/03/stabilizing-naked-functions/#introduction-of-the-naked-asm-macro&quot;&gt;&lt;/a&gt;
  9895. Introduction of the &lt;code&gt;naked_asm!&lt;/code&gt; macro&lt;/h6&gt;
  9896. &lt;p&gt;The body of a naked function must be a single &lt;code&gt;naked_asm!&lt;/code&gt; call. This macro is a blend between &lt;code&gt;asm!&lt;/code&gt; (it is in a function body) and &lt;code&gt;global_asm!&lt;/code&gt; (only some &lt;a href=&quot;https://doc.rust-lang.org/1.88.0/reference/inline-assembly.html#r-asm.operand-type&quot;&gt;operand types&lt;/a&gt; are accepted).&lt;/p&gt;
  9897. &lt;p&gt;The initial implementation of RFC 2972 added lints onto a standard &lt;code&gt;asm!&lt;/code&gt; call in a naked function. This approach made it hard to write clear error messages and documentation. With the dedicated &lt;code&gt;naked_asm!&lt;/code&gt; macro the behavior is much easier to specify.&lt;/p&gt;
  9898. &lt;h6&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/03/stabilizing-naked-functions/#lowering-to-global-asm&quot;&gt;&lt;/a&gt;
  9899. Lowering to &lt;code&gt;global_asm!&lt;/code&gt;&lt;/h6&gt;
  9900. &lt;p&gt;The initial implementation relied on LLVM to lower functions with the &lt;code&gt;naked&lt;/code&gt; attribute for code generation. This approach had two issues:&lt;/p&gt;
  9901. &lt;ul&gt;
  9902. &lt;li&gt;LLVM would sometimes add unexpected additional instructions to what the user wrote.&lt;/li&gt;
  9903. &lt;li&gt;Rust has non-LLVM code generation backends now, and they would have had to implement LLVM's (unspecified!) behavior.&lt;/li&gt;
  9904. &lt;/ul&gt;
  9905. &lt;p&gt;The implementation that is stabilized now instead converts the naked function into a piece of global assembly. The code generation backends can already emit global assembly, and this strategy guarantees that the whole body of the function is just the instructions that the user wrote.&lt;/p&gt;
  9906. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/03/stabilizing-naked-functions/#what-s-next-for-assembly&quot;&gt;&lt;/a&gt;
  9907. What's next for assembly?&lt;/h3&gt;
  9908. &lt;p&gt;We're working on further assembly ergonomics improvements. If naked functions are something you are excited about and (may) use, we'd appreciate you testing these new features and providing feedback on their designs.&lt;/p&gt;
  9909. &lt;h6&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/07/03/stabilizing-naked-functions/#extern-custom-functions&quot;&gt;&lt;/a&gt;
  9910. &lt;code&gt;extern &quot;custom&quot;&lt;/code&gt; functions&lt;/h6&gt;
  9911. &lt;p&gt;Naked functions usually get the &lt;code&gt;extern &quot;C&quot;&lt;/code&gt; calling convention. But often that calling convention is a lie. In many cases, naked functions don't implement an ABI that Rust knows about. Instead they use some custom calling convention that is specific to that function.&lt;/p&gt;
  9912. &lt;p&gt;The &lt;a href=&quot;https://github.com/rust-lang/rust/issues/140829&quot;&gt;&lt;code&gt;abi_custom&lt;/code&gt;&lt;/a&gt; feature adds &lt;code&gt;extern &quot;custom&quot;&lt;/code&gt; functions and blocks, which allows us to correctly write code like this example from &lt;a href=&quot;https://github.com/rust-lang/compiler-builtins/blob/267ae1fa43785448bfb0aebafc4e352c936dd4cf/compiler-builtins/src/arm.rs#L52-L63&quot;&gt;compiler-builtins&lt;/a&gt;:&lt;/p&gt;

  9936. &lt;p&gt;A consequence of using a custom calling convention is that such functions cannot be called using a Rust call expression; the compiler simply does not know how to generate correct code for such a call. Instead the compiler will error when the program does try to call an &lt;code&gt;extern &quot;custom&quot;&lt;/code&gt; function, and the only way to execute the function is using inline assembly.&lt;/p&gt;

With &lt;code&gt;cfg_asm&lt;/code&gt;, that will no longer be necessary.&lt;/p&gt;</description>

  9964. <description>&lt;h3&gt;Highlights&lt;/h3&gt;
  9965. &lt;ul&gt;
  9966. &lt;li&gt;Some Picture-in-Picture improvements have landed recently from some volunteer contributors, and should be going out in Firefox 141 on July 22nd:
  9967. &lt;ul&gt;
  9968. &lt;li&gt;Thanks to new contributor &lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=756346&quot;&gt;nrcrast&lt;/a&gt; for &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1965895&quot;&gt;adding a new PiP wrapper for Peacock, SkyShowtime and Showmax&lt;/a&gt;, overall improving video playback and supporting PiP captions for those sites.&lt;/li&gt;
  9969. &lt;li&gt;Thanks to new contributor &lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=773453&quot;&gt;gaastorgano&lt;/a&gt; for &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1828299&quot;&gt;resolving an issue with the PiP window failing to function when a video is still buffering&lt;/a&gt;&lt;/li&gt;
  9970. &lt;/ul&gt;
  9971. &lt;/li&gt;
  9972. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=565272&quot;&gt;Carlos&lt;/a&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1888486&quot;&gt;contributed a new i18n.getPreferredSystemLanguages WebExtensions API method&lt;/a&gt; (an addition to the i18n discussed in the W3C WebExtensions Community Group and now implemented by Safari and Firefox)&lt;/li&gt;
  9973. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=761236&quot;&gt;Serah Nderi&lt;/a&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1602351&quot;&gt;added the ability&lt;/a&gt; to print stacktrace for logpoints&lt;/li&gt;
  9974. &lt;/ul&gt;
  9975. &lt;p&gt;&lt;img alt=&quot;Printing the stacktrace in logpoint&quot; class=&quot;alignnone size-full wp-image-1857&quot; height=&quot;750&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/06/headlines184_2.png&quot; width=&quot;1370&quot; /&gt;&lt;/p&gt;
  9976. &lt;ul&gt;
  9977. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=762112&quot;&gt;Spencer&lt;/a&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1875524&quot;&gt;introduced a WindowManager.supportsWindows() helper&lt;/a&gt; to our implementation of WebDriver BiDi and Marionette to make it easier to detect whether the application supports multiple windows.&lt;/li&gt;
  9978. &lt;/ul&gt;
  9979. &lt;h3&gt;Friends of the Firefox team&lt;/h3&gt;
  9980. &lt;h3&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/buglist.cgi?title=Resolved%20bugs%20(excluding%20employees)&amp;amp;quicksearch=1838053%2C1968579%2C1602351%2C1970898%2C1828933%2C1965895%2C1888486%2C1959616%2C1809372%2C1959029%2C1972301%2C1828299%2C1973100%2C1875524%2C1973280&amp;amp;list_id=17601093&quot;&gt;Resolved bugs (excluding employees)&lt;/a&gt;&lt;/h3&gt;
  9981. &lt;h4&gt;Volunteers that fixed more than one bug&lt;/h4&gt;
  9982. &lt;ul&gt;
  9983. &lt;li&gt;Gabriel Astorgano&lt;/li&gt;
  9984. &lt;li&gt;Gregory Pappas [:gregp]&lt;/li&gt;
  9985. &lt;li&gt;Masatoshi Kimura [:emk]&lt;/li&gt;
  9986. &lt;/ul&gt;
  9987. &lt;h4&gt;New contributors (🌟 = first patch)&lt;/h4&gt;
  9988. &lt;ul&gt;
  9989. &lt;li&gt;Gabriel Astorgano:
  9990. &lt;ul&gt;
  9991. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1828299&quot;&gt;Bug 1828299&lt;/a&gt;  — [Picture-in-Picture] Popping out the video when it’s buffering causes the Play/Pause button to get stuck [display] as the Play button + this button doesn’t work&lt;/li&gt;
  9992. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1959029&quot;&gt;Bug 1959029&lt;/a&gt; — Sidebar icon does not reflect sidebar position (left/right)&lt;/li&gt;
  9993. &lt;/ul&gt;
  9994. &lt;/li&gt;
  9995. &lt;li&gt;Jason Jones: &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1959616&quot;&gt;Bug 1959616&lt;/a&gt; —  Move browser-window UI functionality for session restore from browser.js and BrowserGlue.sys.mjs to a session restore module&lt;/li&gt;
  9996. &lt;li&gt;🌟Nick Crast: &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1965895&quot;&gt;Bug 1965895&lt;/a&gt; — Add Peacock, SkyShowtime, Showmax, and Now TV to Picture-In-Picture video wrappers&lt;/li&gt;
  9997. &lt;/ul&gt;
  9998. &lt;h3&gt;Project Updates&lt;/h3&gt;
  9999. &lt;h4&gt;Add-ons / Web Extensions&lt;/h4&gt;
  10000. &lt;h5&gt;WebExtensions Framework&lt;/h5&gt;
  10001. &lt;ul&gt;
  10002. &lt;li&gt;Fixed attention dot on pinned extension not updated in non-active windows – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1967564&quot;&gt;Bug 1967564&lt;/a&gt;&lt;/li&gt;
  10003. &lt;li&gt;Fixed data collection permissions removed from the manifest between add-on updates not being revoked from the set of granted permissions (fixed in Nightly 141 and uplifted to Beta 140) – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971414&quot;&gt;Bug 1971414&lt;/a&gt;&lt;/li&gt;
  10004. &lt;li&gt;Set a fixed uuid in the moz-extension url for the webcompat built-in add-on, as a short term mitigation to prevent webcompat moz-extensions urls to be used for user fingerprinting – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1717672&quot;&gt;Bug 1717672&lt;/a&gt;&lt;/li&gt;
  10005. &lt;/ul&gt;
  10006. &lt;h5&gt;WebExtension APIs&lt;/h5&gt;
  10007. &lt;ul&gt;
  10008. &lt;li&gt;Fixed a regression introduced in Firefox 139, which prevented browser.notifications.create non-system notifications from showing icons set as data and/or blob urls (fixed in Nightly 141, uplift requested to ESR 140) – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970075&quot;&gt;Bug 1970075&lt;/a&gt;&lt;/li&gt;
  10009. &lt;li&gt;Emilio investigated and fixed a recent regression related to the browserSettings.useDocumentFonts, which was preventing the browser settings from affecting the webpages until the next page reload (regressed in 138, fixed in nightly 142 and uplift requested for ESR 140 and Beta 141)  –  &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972971&quot;&gt;Bug 1972971&lt;/a&gt;&lt;/li&gt;
  10010. &lt;li&gt;Christina introduced support for filtering by cookieStoreId the tabs.onUpdated events – &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1960011&quot;&gt;Bug 1960011&lt;/a&gt;&lt;/li&gt;
  10011. &lt;/ul&gt;
  10012. &lt;h4&gt;DevTools&lt;/h4&gt;
  10013. &lt;ul&gt;
  10014. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=719810&quot;&gt;Alex Jakobi [:ajakobi]&lt;/a&gt; added Dynamic toolbar in RDM, under the devtools.responsive.dynamicToolbar.enabled pref (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970616&quot;&gt;Bug 1970616&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970617&quot;&gt;Bug 1970617&lt;/a&gt;, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970618&quot;&gt;Bug 1970618&lt;/a&gt;)&lt;/li&gt;
  10015. &lt;/ul&gt;
  10016. &lt;p&gt;&lt;img alt=&quot;Dynamic toolbar in RDM&quot; class=&quot; wp-image-1859 aligncenter&quot; height=&quot;636&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/06/headlines184_4.gif&quot; width=&quot;492&quot; /&gt;&lt;/p&gt;
  10017. &lt;ul&gt;
  10018. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=219126&quot;&gt;James Teh [:Jamie]&lt;/a&gt; made it possible to pick menu items in XUL menus with the accessibility inspector picker (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972759&quot;&gt;Bug 1972759&lt;/a&gt;)&lt;/li&gt;
  10019. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=763731&quot;&gt;Holger Benl [:hbenl]&lt;/a&gt; fixed the color picker in RDM when touch simulation is enabled (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1932143&quot;&gt;Bug 1932143&lt;/a&gt;) and made sure the underlying screenshot we take for the picker is updated when the page is resized (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1295057&quot;&gt;Bug 1295057&lt;/a&gt;)&lt;/li&gt;
  10020. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=557153&quot;&gt;Nicolas Chevobbe [:nchevobbe]&lt;/a&gt; invalid cookies error message in the storage panel (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1967707&quot;&gt;Bug 1967707&lt;/a&gt;)&lt;/li&gt;
  10021. &lt;/ul&gt;
  10022. &lt;p&gt;&lt;img alt=&quot;Invalid cookies error message is displayed in DevTools storage panel.&quot; class=&quot;alignnone size-full wp-image-1856&quot; height=&quot;688&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/06/headlines184_1.png&quot; width=&quot;1580&quot; /&gt;&lt;/p&gt;
  10023. &lt;ul&gt;
  10024. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=656417&quot;&gt;Hubert Boma Manilla (:bomsy)&lt;/a&gt; fixed an issue in the Debugger when switching sources while the file search panel was open (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971094&quot;&gt;Bug 1971094&lt;/a&gt;)&lt;/li&gt;
  10025. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/user_profile?user_id=656417&quot;&gt;Hubert Boma Manilla (:bomsy)&lt;/a&gt; also fixed inline previews and preview popup for expressions which aren’t in a function scope (&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1957885&quot;&gt;Bug 1957885&lt;/a&gt;)&lt;/li&gt;
  10026. &lt;/ul&gt;
  10027. &lt;h4&gt;WebDriver BiDi&lt;/h4&gt;
  10028. &lt;ul&gt;
  10029. &lt;li&gt;Henrik &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1967659&quot;&gt;updated our in-tree Puppeteer to version 24.10.0&lt;/a&gt; and &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970839&quot;&gt;upgraded Node.js to 22.16.0 across all test jobs&lt;/a&gt; to enable ESM support by default.&lt;/li&gt;
  10030. &lt;li&gt;Ben Chatterton &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1958723&quot;&gt;improved the error message shown when attempting to permanently install an unpacked, unsigned web extension&lt;/a&gt;.&lt;/li&gt;
  10031. &lt;li&gt;To address unnecessary 200ms delays on each click; even when no navigation occurred; Henrik &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972271&quot;&gt;lowered the Selenium click-and-wait timeout for possible navigations to 50ms&lt;/a&gt; for backward compatibility. The timeout is now also configurable and can be completely disabled by users through a &lt;a href=&quot;https://firefox-source-docs.mozilla.org/testing/marionette/Prefs.html#marionette-navigate-after-click-enabled&quot;&gt;preference&lt;/a&gt;.&lt;/li&gt;
  10032. &lt;/ul&gt;
  10033. &lt;h4&gt;Lint, Docs and Workflow&lt;/h4&gt;
  10034. &lt;ul&gt;
  10035. &lt;li&gt;:gerard-majax &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1970845&quot;&gt;added a linter&lt;/a&gt; to remind developers to use proper&lt;a href=&quot;https://firefox-source-docs.mozilla.org/code-quality/lint/linters/dot-mozilla-reference.html&quot;&gt; XDG handling rather than .mozilla directory references&lt;/a&gt;.&lt;/li&gt;
  10036. &lt;li&gt;Standard8 fixed the rejected-words and codespell linters to &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971413&quot;&gt;properly check .jsx files&lt;/a&gt; (a typo meant they were checking .jxs files).&lt;/li&gt;
  10037. &lt;li&gt;Standard8 also tidied up some of the &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1969266&quot;&gt;top-level ESLint configuration files following the v9 upgrade&lt;/a&gt;.&lt;/li&gt;
  10038. &lt;/ul&gt;
  10039. &lt;h4&gt;Migration Improvements&lt;/h4&gt;
  10040. &lt;ul&gt;
  10041. &lt;li&gt;&lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971702&quot;&gt;Opera has changed where and how they store profile data in a recent release&lt;/a&gt;, which has broken importing from that browser. We’re hoping to get this sorted during the 142 cycle.&lt;/li&gt;
  10042. &lt;/ul&gt;
  10043. &lt;h4&gt;New Tab Page&lt;/h4&gt;
  10044. &lt;ul&gt;
  10045. &lt;li&gt;Thanks to the WebExtensions team, we’ve got line-of-sight for performing train-hopping to the release channel starting with Firefox 142. The plan is to use Nimbus / Experimenter to distribute the newtab XPI, rather than Balrog.
  10046. &lt;ul&gt;
  10047. &lt;li&gt;See &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1973223&quot;&gt;this bug&lt;/a&gt; and what it blocks for more details&lt;/li&gt;
  10048. &lt;/ul&gt;
  10049. &lt;/li&gt;
  10050. &lt;li&gt;We’ve rolled out a change that removes story descriptions, to streamline the contents on the page!&lt;/li&gt;
  10051. &lt;/ul&gt;
  10052. &lt;p&gt;&lt;img alt=&quot;The Firefox new tab page showing six stories without descriptive text.&quot; class=&quot;alignnone size-full wp-image-1858&quot; height=&quot;651&quot; src=&quot;https://blog.nightly.mozilla.org/files/2025/06/headlines184_3.png&quot; width=&quot;991&quot; /&gt;&lt;/p&gt;
  10053. &lt;ul&gt;
  10054. &lt;li&gt;The team has landed some support for more variations of showing “trending searches” on the newtab page, which we’ll be experimenting with soon.&lt;/li&gt;
  10055. &lt;li&gt;Nina has been on a tear, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971663&quot;&gt;cleaning&lt;/a&gt; &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971943&quot;&gt;up&lt;/a&gt; a bunch of Pocket-related code in the newtab codebase. Most recently, &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1972483&quot;&gt;she removed a bunch of telemetry support for Pocket events&lt;/a&gt;.&lt;/li&gt;
  10056. &lt;/ul&gt;
  10057. &lt;h4&gt;Picture-in-Picture&lt;/h4&gt;
  10058. &lt;ul&gt;
  10059. &lt;li&gt;kpatenio &lt;a href=&quot;https://bugzilla.mozilla.org/show_bug.cgi?id=1971189&quot;&gt;fixed PiP play/pause not working when watching videos on the Apple events page&lt;/a&gt;&lt;/li&gt;
  10060. &lt;/ul&gt;
  10061. &lt;h4&gt;Profile Management&lt;/h4&gt;
  10062. &lt;ul&gt;

  10099. <title>Mozilla Localization (L10N): Reconnecting in Berlin: A Celebration of Mozilla’s Localization Community</title>
  10100. <guid isPermaLink="false">https://blog.mozilla.org/l10n/?p=1770</guid>
  10101. <link>https://blog.mozilla.org/l10n/2025/06/26/reconnecting-in-berlin-a-celebration-of-mozillas-localization-community/</link>
  10102. <description>&lt;p&gt;Something we’ve long known at Mozilla is that our localization community thrives on personal connections. For years, regional meetups brought volunteers and staff together multiple times a year — forging friendships, sharing knowledge, and collectively advancing the mission of a multilingual, open internet.&lt;/p&gt;
  10103. &lt;p&gt;After a five-year pause, we’re thrilled to share that in June 2025, we re-ignited that tradition with a pilot localization meetup at the Mozilla Berlin office; it was everything we hoped for, and more.&lt;/p&gt;
  10104. &lt;p&gt;&lt;a href=&quot;https://blog.mozilla.org/l10n/files/2025/06/image1.jpg&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;size-full wp-image-1771&quot; height=&quot;1132&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/06/image1.jpg&quot; width=&quot;1600&quot; /&gt;&lt;/a&gt;&lt;/p&gt;
  10105. &lt;h3&gt;A Weekend of Community, Collaboration, and Fresh Energy&lt;/h3&gt;
  10106. &lt;p&gt;Fourteen volunteers from 11 different locales gathered for a weekend full of shared ideas, meaningful conversations, and collaborative problem-solving. For many, it was their first time meeting fellow contributors in person, people they’d worked with for years, but only ever known through usernames and chat windows. For others, it was a long-awaited reunion, finally bringing back to life connections that had existed solely online since the last wave of community meetups.&lt;/p&gt;
  10107. &lt;blockquote&gt;&lt;p&gt;&lt;em&gt;“We now feel more connected and will work together more closely,”&lt;/em&gt; shared one participant, reflecting on the emotional impact of finally connecting face-to-face.&lt;/p&gt;&lt;/blockquote&gt;
  10108. &lt;p&gt;Throughout the weekend, we dove into topics ranging from community building to localization tooling. Some standout moments included:&lt;/p&gt;
  10109. &lt;ul&gt;
  10110. &lt;li&gt;Candid discussions about what it means to &lt;b&gt;lead within a localization community&lt;/b&gt;, the challenges of maintaining momentum, and what kind of support really makes a difference.&lt;/li&gt;
  10111. &lt;li&gt;&lt;a href=&quot;https://pontoon.mozilla.org/contributors/UfUyEREQhwicysBna3Wj8G2H69Q/&quot;&gt;&lt;b&gt;David&lt;/b&gt;&lt;/a&gt;&lt;b&gt;’s lightning talk on the Sicilian language and community&lt;/b&gt;, which sparked conversations about linguistic diversity and revitalizing regional languages through digitalization.&lt;/li&gt;
  10112. &lt;li&gt;&lt;b&gt;Collaborative Pontoon brainstorming session&lt;/b&gt;, where localizers took the lead in proposing enhancements, suggesting new features, and sharing pain points — and some even supporting each other with development setup and hands-on exploration.&lt;/li&gt;
  10113. &lt;/ul&gt;
  10114. &lt;p&gt;And of course, there was time for laughter, great food, and spontaneous late-night ideas that could only come from being in the same room together.&lt;/p&gt;
  10115. &lt;blockquote&gt;&lt;p&gt;As one localizer put it: &lt;em&gt;“The event gave me fresh energy and ideas to contribute more actively to Mozilla.”&lt;/em&gt;&lt;/p&gt;&lt;/blockquote&gt;
  10116. &lt;p&gt;&lt;a href=&quot;https://blog.mozilla.org/l10n/files/2025/06/image2.jpg&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;alignnone size-full wp-image-1772&quot; height=&quot;1205&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/06/image2.jpg&quot; width=&quot;1600&quot; /&gt;&lt;/a&gt;&lt;/p&gt;
  10117. &lt;h3&gt;Behind the Scenes&lt;/h3&gt;
  10118. &lt;p&gt;Organizing this meetup — especially after a multi-year hiatus — was a complex endeavor. Though we were eager to bring people together in the first half of the year, it took nearly nine months of planning. In the end, only two weekends aligned with enough staff availability to make the event possible.&lt;/p&gt;
  10119. &lt;p&gt;To keep things focused and manageable for a pilot, we made a few strategic decisions:&lt;/p&gt;
  10120. &lt;ul&gt;
  10121. &lt;li&gt;&lt;b&gt;Location:&lt;/b&gt; with a local staff member on the ground and access to Mozilla’s Berlin office, we could streamline logistics — from restaurant bookings and lunch deliveries to helping attendees navigate international travel with clear guidance and local support.&lt;/li&gt;
  10122. &lt;li&gt;&lt;b&gt;Participant selection:&lt;/b&gt; we prioritized inviting contributors who were highly active in Pontoon, and whose travel would be cost-effective and visa-free. This helped reduce uncertainty and made the event more accessible.&lt;/li&gt;
  10123. &lt;li&gt;&lt;b&gt;Budget-aware planning:&lt;/b&gt; we extended invitations to 34 community members and received interest from 27. Due to scheduling overlaps, 14 were ultimately able to attend.&lt;/li&gt;
  10124. &lt;/ul&gt;
  10125. &lt;h3&gt;Why This Matters&lt;/h3&gt;
  10126. &lt;p&gt;Events like this don’t just strengthen Mozilla’s localization work, they strengthen Mozilla as a whole. Contributors left Berlin feeling recognized, energized, and motivated, and organizers left with a renewed sense of purpose and clarity about how vital it is to invest in human connection.&lt;/p&gt;
  10127. &lt;p&gt;It also gave us space to hear directly from contributors — not in surveys or chat threads, but in real time, with nuance and context. Those conversations helped surface both immediate ideas for improvement and deeper questions about what sustainable, meaningful participation looks like in today’s Mozilla. It was a reminder that strong localization doesn’t just come from good tools and processes, but from mutual trust, shared ownership, and space to collaborate openly.&lt;/p&gt;
  10128. &lt;p&gt;&lt;a href=&quot;https://blog.mozilla.org/l10n/files/2025/06/image3.jpg&quot;&gt;&lt;img alt=&quot;&quot; class=&quot;alignnone size-full wp-image-1773&quot; height=&quot;1600&quot; src=&quot;https://blog.mozilla.org/l10n/files/2025/06/image3.jpg&quot; width=&quot;1205&quot; /&gt;&lt;/a&gt;&lt;/p&gt;
  10129. &lt;h3&gt;Looking Ahead&lt;/h3&gt;
  10130. &lt;p&gt;We’re now regrouping to reflect on lessons learned and to explore if it’s possible to scale these meetups going forward. That means thinking carefully about aspects like:&lt;/p&gt;
  10131. &lt;ul&gt;
  10132. &lt;li&gt;How do we support communities in regions where Mozilla has no local staff?&lt;/li&gt;
  10133. &lt;li&gt;How do we navigate unknowns, like visa requirements, more complex traveling logistics, etc.?&lt;/li&gt;
  10134. &lt;li&gt;How do we sustainably host more meetups per year and ensure they’re just as impactful?&lt;/li&gt;
  10135. &lt;/ul&gt;
  10136. &lt;p&gt;One thing is certain: this pilot proved once again the value of in-person community building. It re-affirmed something our community has said all along — that being together matters.&lt;/p&gt;
  10137. &lt;p&gt;We’re incredibly grateful to everyone who participated, and we’re excited about the possibilities ahead. Whether you’re a seasoned localizer or just getting started, we hope this story inspires you. Your contributions make Mozilla possible  and we truly hope we can celebrate that together, in more places around the world.&lt;/p&gt;</description>

  10142. <title>The Rust Programming Language Blog: Announcing Rust 1.88.0</title>
  10143. <guid isPermaLink="true">https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/</guid>
  10144. <link>https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/</link>
  10145. <description>&lt;p&gt;The Rust team is happy to announce a new version of Rust, 1.88.0. Rust is a programming language empowering everyone to build reliable and efficient software.&lt;/p&gt;
  10146. &lt;p&gt;If you have a previous version of Rust installed via &lt;code&gt;rustup&lt;/code&gt;, you can get 1.88.0 with:&lt;/p&gt;
  10147. &lt;pre class=&quot;z-code&quot;&gt;&lt;code&gt;&lt;span class=&quot;z-text z-plain&quot;&gt;$ rustup update stable
  10148. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  10149. &lt;p&gt;If you don't have it already, you can &lt;a href=&quot;https://www.rust-lang.org/install.html&quot;&gt;get &lt;code&gt;rustup&lt;/code&gt;&lt;/a&gt; from the appropriate page on our website, and check out the &lt;a href=&quot;https://doc.rust-lang.org/stable/releases.html#version-1880-2025-06-26&quot;&gt;detailed release notes for 1.88.0&lt;/a&gt;.&lt;/p&gt;
  10150. &lt;p&gt;If you'd like to help us out by testing future releases, you might consider updating locally to use the beta channel (&lt;code&gt;rustup default beta&lt;/code&gt;) or the nightly channel (&lt;code&gt;rustup default nightly&lt;/code&gt;). Please &lt;a href=&quot;https://github.com/rust-lang/rust/issues/new/choose&quot;&gt;report&lt;/a&gt; any bugs you might come across!&lt;/p&gt;
  10151. &lt;h3&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/#what-s-in-1-88-0-stable&quot;&gt;&lt;/a&gt;
  10152. What's in 1.88.0 stable&lt;/h3&gt;
  10153. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/#let-chains&quot;&gt;&lt;/a&gt;
  10154. Let chains&lt;/h4&gt;
  10155. &lt;p&gt;This feature allows &lt;code&gt;&amp;amp;&amp;amp;&lt;/code&gt;-chaining &lt;code&gt;let&lt;/code&gt; statements inside &lt;code&gt;if&lt;/code&gt; and &lt;code&gt;while&lt;/code&gt; conditions, even intermingling with boolean expressions, so there is less distinction between &lt;code&gt;if&lt;/code&gt;/&lt;code&gt;if let&lt;/code&gt; and &lt;code&gt;while&lt;/code&gt;/&lt;code&gt;while let&lt;/code&gt;. The patterns inside the &lt;code&gt;let&lt;/code&gt; sub-expressions can be irrefutable or refutable, and bindings are usable in later parts of the chain as well as the body.&lt;/p&gt;
  10156. &lt;p&gt;For example, this snippet combines multiple conditions which would have required nesting &lt;code&gt;if let&lt;/code&gt; and &lt;code&gt;if&lt;/code&gt; blocks before:&lt;/p&gt;
  10157. &lt;pre class=&quot;language-rust z-code&quot;&gt;&lt;code class=&quot;language-rust&quot;&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;&lt;span class=&quot;z-keyword z-control z-rust&quot;&gt;if&lt;/span&gt; &lt;span class=&quot;z-storage z-type z-rust&quot;&gt;let&lt;/span&gt; &lt;span class=&quot;z-meta z-path z-rust&quot;&gt;Channel&lt;span class=&quot;z-punctuation z-accessor z-rust&quot;&gt;::&lt;/span&gt;&lt;/span&gt;Stable&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-group z-begin z-rust&quot;&gt;(&lt;/span&gt;v&lt;/span&gt;&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-group z-end z-rust&quot;&gt;)&lt;/span&gt;&lt;/span&gt; &lt;span class=&quot;z-keyword z-operator z-assignment z-rust&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;z-support z-function z-rust&quot;&gt;release_info&lt;/span&gt;&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-group z-begin z-rust&quot;&gt;(&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-group z-end z-rust&quot;&gt;)&lt;/span&gt;&lt;/span&gt;
  10158. &lt;/span&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;    &lt;span class=&quot;z-keyword z-operator z-logical z-rust&quot;&gt;&amp;amp;&amp;amp;&lt;/span&gt; &lt;span class=&quot;z-storage z-type z-rust&quot;&gt;let&lt;/span&gt; Semver &lt;span class=&quot;z-meta z-block z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-block z-begin z-rust&quot;&gt;{&lt;/span&gt; major&lt;span class=&quot;z-punctuation z-separator z-rust&quot;&gt;,&lt;/span&gt; minor&lt;span class=&quot;z-punctuation z-separator z-rust&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;z-keyword z-operator z-range z-rust&quot;&gt;..&lt;/span&gt; &lt;/span&gt;&lt;span class=&quot;z-meta z-block z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-block z-end z-rust&quot;&gt;}&lt;/span&gt;&lt;/span&gt; &lt;span class=&quot;z-keyword z-operator z-assignment z-rust&quot;&gt;=&lt;/span&gt; v
  10159. &lt;/span&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;    &lt;span class=&quot;z-keyword z-operator z-logical z-rust&quot;&gt;&amp;amp;&amp;amp;&lt;/span&gt; major &lt;span class=&quot;z-keyword z-operator z-comparison z-rust&quot;&gt;==&lt;/span&gt; &lt;span class=&quot;z-constant z-numeric z-integer z-decimal z-rust&quot;&gt;1&lt;/span&gt;
  10160. &lt;/span&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;    &lt;span class=&quot;z-keyword z-operator z-logical z-rust&quot;&gt;&amp;amp;&amp;amp;&lt;/span&gt; minor &lt;span class=&quot;z-keyword z-operator z-comparison z-rust&quot;&gt;==&lt;/span&gt; &lt;span class=&quot;z-constant z-numeric z-integer z-decimal z-rust&quot;&gt;88&lt;/span&gt;
  10161. &lt;/span&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;&lt;span class=&quot;z-meta z-block z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-block z-begin z-rust&quot;&gt;{&lt;/span&gt;
  10162. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;&lt;span class=&quot;z-meta z-block z-rust&quot;&gt;    &lt;span class=&quot;z-support z-macro z-rust&quot;&gt;println!&lt;/span&gt;&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-group z-begin z-rust&quot;&gt;(&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-string z-quoted z-double z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-definition z-string z-begin z-rust&quot;&gt;&quot;&lt;/span&gt;`let_chains` was stabilized in this version&lt;span class=&quot;z-punctuation z-definition z-string z-end z-rust&quot;&gt;&quot;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-meta z-group z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-group z-end z-rust&quot;&gt;)&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-punctuation z-terminator z-rust&quot;&gt;;&lt;/span&gt;
  10163. &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;z-source z-rust&quot;&gt;&lt;span class=&quot;z-meta z-block z-rust&quot;&gt;&lt;/span&gt;&lt;span class=&quot;z-meta z-block z-rust&quot;&gt;&lt;span class=&quot;z-punctuation z-section z-block z-end z-rust&quot;&gt;}&lt;/span&gt;&lt;/span&gt;
  10164. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  10165. &lt;p&gt;Let chains are only available in the Rust 2024 edition, as this feature depends on the &lt;a href=&quot;https://doc.rust-lang.org/edition-guide/rust-2024/temporary-if-let-scope.html&quot;&gt;&lt;code&gt;if let&lt;/code&gt; temporary scope&lt;/a&gt; change for more consistent drop order.&lt;/p&gt;
  10166. &lt;p&gt;Earlier efforts tried to work with all editions, but some difficult edge cases threatened the integrity of the implementation. 2024 made it feasible, so please upgrade your crate's edition if you'd like to use this feature!&lt;/p&gt;
  10167. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/#naked-functions&quot;&gt;&lt;/a&gt;
  10168. Naked functions&lt;/h4&gt;
  10169. &lt;p&gt;Rust now supports writing naked functions with no compiler-generated epilogue and prologue, allowing full control over the generated assembly for a particular function. This is a more ergonomic alternative to defining functions in a &lt;code&gt;global_asm!&lt;/code&gt; block. A naked function is marked with the &lt;code&gt;#[unsafe(naked)]&lt;/code&gt; attribute, and its body consists of a single &lt;code&gt;naked_asm!&lt;/code&gt; call.&lt;/p&gt;

  10179. &lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
  10180. &lt;p&gt;The handwritten assembly block defines the &lt;em&gt;entire&lt;/em&gt; function body: unlike non-naked functions, the compiler does not add any special handling for arguments or return values. Naked functions are used in low-level settings like Rust's &lt;a href=&quot;https://github.com/rust-lang/compiler-builtins&quot;&gt;&lt;code&gt;compiler-builtins&lt;/code&gt;&lt;/a&gt;, operating systems, and embedded applications.&lt;/p&gt;
  10181. &lt;p&gt;Look for a more detailed post on this soon!&lt;/p&gt;
  10182. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/#boolean-configuration&quot;&gt;&lt;/a&gt;
  10183. Boolean configuration&lt;/h4&gt;
  10184. &lt;p&gt;The &lt;code&gt;cfg&lt;/code&gt; predicate language now supports boolean literals, &lt;code&gt;true&lt;/code&gt; and &lt;code&gt;false&lt;/code&gt;, acting as a configuration that is always enabled or disabled, respectively. This works in Rust &lt;a href=&quot;https://doc.rust-lang.org/reference/conditional-compilation.html&quot;&gt;conditional compilation&lt;/a&gt; with &lt;code&gt;cfg&lt;/code&gt; and &lt;code&gt;cfg_attr&lt;/code&gt; attributes and the built-in &lt;code&gt;cfg!&lt;/code&gt; macro, and also in Cargo &lt;code&gt;[target]&lt;/code&gt; tables in both &lt;a href=&quot;https://doc.rust-lang.org/cargo/reference/config.html#target&quot;&gt;configuration&lt;/a&gt; and &lt;a href=&quot;https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#platform-specific-dependencies&quot;&gt;manifests&lt;/a&gt;.&lt;/p&gt;
  10185. &lt;p&gt;Previously, empty predicate lists could be used for unconditional configuration, like &lt;code&gt;cfg(all())&lt;/code&gt; for enabled and &lt;code&gt;cfg(any())&lt;/code&gt; for disabled, but this meaning is rather implicit and easy to get backwards. &lt;code&gt;cfg(true)&lt;/code&gt; and &lt;code&gt;cfg(false)&lt;/code&gt; offer a more direct way to say what you mean.&lt;/p&gt;
  10186. &lt;p&gt;See &lt;a href=&quot;https://rust-lang.github.io/rfcs/3695-cfg-boolean-literals.html&quot;&gt;RFC 3695&lt;/a&gt; for more background!&lt;/p&gt;
  10187. &lt;h4&gt;&lt;a class=&quot;anchor&quot; href=&quot;https://blog.rust-lang.org/2025/06/26/Rust-1.88.0/#cargo-automatic-cache-cleaning&quot;&gt;&lt;/a&gt;
  10188. Cargo automatic cache cleaning&lt;/h4&gt;
  10189. &lt;p&gt;Starting in 1.88.0, Cargo will automatically run garbage collection on the cache in its home directory!&lt;/p&gt;
  10190. &lt;p&gt;When building, Cargo downloads and caches crates needed as dependencies. Historically, these downloaded files would never be cleaned up, leading to an unbounded amount of disk usage in Cargo's home directory. In this version, Cargo introduces a garbage collection mechanism to automatically clean up old files (e.g. &lt;code&gt;.crate&lt;/code&gt; files). Cargo will remove files downloaded from the network if not accessed in 3 months, and files obtained from the local system if not accessed in 1 month. Note that this automatic garbage collection will not take place if running offline (using &lt;code&gt;--offline&lt;/code&gt; or &lt;code&gt;--frozen&lt;/code&gt;).&lt;/p&gt;
  10191. &lt;p&gt;Cargo 1.78 and newer track the access information needed for this garbage collection. This was introduced well before the actual cleanup that's starting now, in order to reduce cache churn for those that still use prior versions. If you regularly use versions of Cargo even older than 1.78, in addition to running current versions of Cargo, and you expect to have some crates accessed exclusively by the older versions of Cargo and don't want to re-download those crates every ~3 months, you may wish to set &lt;code&gt;cache.auto-clean-frequency = &quot;never&quot;&lt;/code&gt; in the Cargo configuration, as described in the &lt;a href=&quot;https://doc.rust-lang.org/nightly/cargo/reference/config.html#cache&quot;&gt;docs&lt;/a&gt;.&lt;/p&gt;
  10192. &lt;p&gt;For more information, see the original &lt;a href=&quot;https://blog.rust-lang.org/2023/12/11/cargo-cache-cleaning/&quot;&gt;unstable announcement&lt;/a&gt; of this feature. Some parts of that design remain unstable, like the &lt;code&gt;gc&lt;/code&gt; subcommand tracked in &lt;a href=&quot;https://github.com/rust-lang/cargo/issues/13060&quot;&gt;cargo#13060&lt;/a&gt;, so there's still more to look forward to!&lt;/p&gt;

  10228. Other changes&lt;/h4&gt;
  10229. &lt;p&gt;The &lt;code&gt;i686-pc-windows-gnu&lt;/code&gt; target has been demoted to Tier 2, as mentioned in an &lt;a href=&quot;https://blog.rust-lang.org/2025/05/26/demoting-i686-pc-windows-gnu/&quot;&gt;earlier post&lt;/a&gt;. This won't have any immediate effect for users, since both the compiler and standard library tools will still be distributed by &lt;code&gt;rustup&lt;/code&gt; for this target. However, with less testing than it had at Tier 1, it has more chance of accumulating bugs in the future.&lt;/p&gt;
  10230. &lt;p&gt;Check out everything that changed in &lt;a href=&quot;https://github.com/rust-lang/rust/releases/tag/1.88.0&quot;&gt;Rust&lt;/a&gt;, &lt;a href=&quot;https://doc.rust-lang.org/nightly/cargo/CHANGELOG.html#cargo-188-2025-06-26&quot;&gt;Cargo&lt;/a&gt;, and &lt;a href=&quot;https://github.com/rust-lang/rust-clippy/blob/master/CHANGELOG.md#rust-188&quot;&gt;Clippy&lt;/a&gt;.&lt;/p&gt;
