• Firefox 75.0 is our latest stable release.
• Firefox 76 is in the Beta channel and makes it out to our stable release audience next week on May 5th. We're in RC week now.
• Firefox 77 is in the Nightly channel and it will arrive for our stable release users on June 2nd. The soft code freeze is this Thursday. If you've got risky changes or want to pref on a new feature, please do so before Thursday. Over the last week there have been about 440 bugs resoved as Fixed including these notable ones:
  • The Firefox address bar got a lot smarter. It now uses the Public Suffix List to show search results for lookups with a dot in them that are not actual domains. Putting something like foo.bar in the address bar will ow search for it rather than trying to load it as if it was a web address. This was fixed at bug 1080682. Also, entering an email address into the address bar will now perform a search rather than trying to load it as if it was a web login attempt. This was bug 1412985. Finally, entering a data:url with a space and a question mark now works as expected, loading it as a data:url rather than a search string. See bug 1613276 for details.
  • We now have an enterprise policy for PDF handling that allows an enterprise manager to disable pdf.js in favor of a system PDF viewer. This was implemented at bug 792816.
  • There is a new web technology based Firefox Installer. This should be easier to update and maintain than the old native stub installer. All the details at bug 1596812.
  • Gecko now handles word boundaries properly on Southeast Asian languages without interword spaces. This makes selecting (and other text actions) easier for Thai, Khmer, Lao, and other languages. This was fixed at bug 425915.
  • Gecko got support fro ARIA reflection at bug 1628418. This is part of the Accessibility Object Model and gives web authors tools to make custom elements accessible.
  • Last but not least, XUL Grids were all replaced in Firefox and support was removed from Gecko. This was bug 1520625.

2020-04-20

• Firefox 75.0 is our latest stable release. 75 shipped about two weeks ago on April 7 and includes, among other things, a totally revamped address bar.
• Firefox 76 is in the Beta channel and makes it out to our stable release audience in about two weeks on May 5th. Beta 7, 8, and 9 go out today, Wednesday, and Friday. And that means that next week is RC week. As a reminder, our four week release cycle consists of three weeks of three betas each, followed by one week of release candidates.
• Firefox 77 is in the Nightly channel and it will arrive for our stable release users on June 2nd. There are ten more days of active development on Nightly before we hit the soft code freeze, meaning that developers should not land code that is deemed risky and that new features controlled by a pref not be activated during this week. Over the last week there have been about 400 bugs resolved as Fixed including these notable ones:
  • Firefox now allows for merging content-security-policy headers provided by multiple extensions. Before this change, users could get unexpected results as it was possible for two extensions each setting a content-security-policy to conflict.
  • The padding for bookmark toolbar items has been increased for easier user with touchscreens. Before this change, the new address bar's expansion made it more difficult than it needed to be to activate bookmarks with touch.
  • Firefox now has a new prompt type called tab modal system prompts. Where possible, our current system window prompts will be switched over to these new prompts.
  • The last of the extended validation code and prefs have been removed. Users can no longer re-enable the EV UI in about:config.
  • The remote Canvas 2D has been enabled in Windows Nightly builds. This is part of the work to remove GPU access from the content process, so that we can improve the sandbox policy.
  • Cookie purging has been enabled on Nightly. This is part of Enhanced Tracking Protection phase 2. We now clear cookies from sites on the TP list that you have been redirected to but don’t interact with.
  • Fenix for Android now supports landmark navigation for screen readers and typing text with a screen reader is much more usable now.

2020-04-13

  • an easier way to install and use Firefox on Linux with Flatpak support.
  • Direct Composition support for Windows gets us even better performance and closer to our goal of shipping WebRender .
  • For web developers, we will now support the "loading" attribute which when set to "lazy" will allow for images to only load when they are within the viewport, speeding up page loading for uses and decreasing network bandwidth.
  • Another great update for web developers is the new Instant evaluation for Console expressions. The feature lets developers identify and fix errors more rapidly than before. As long as expressions typed into the Web Console are side-effect free, their results will be previewed while you type.

Over the last week there have been about 400 bugs resolved as Fixed including these notable ones:

• Firefox 73.0.1 is our current stable release. The dot release addressed a crash with third-party security software, and a loss of browser functionality running in Windows compatibility mode or having custom anti-exploit settings.
• Firefox 74 is in the Beta channel. We're two weeks in to a four week Beta cycle (after a 5 week Nightly cycle.) Beta 7 goes out today, 8 on Wednesday, and 9 on Friday. Next week is RC week, and 74 goes live on Tuesday, March 10th.

Over the last two weeks there have been about 800 bugs resolved as fixed in Nightly including these notable ones.
  • Firefox now has support for lazy loading of images. Images are often the heaviest part of a page and some or all can be off-screen when the page first loads. Avoiding loading off-screen images is a nice win because it means the content in the view port loads faster, bandwidth is saved, and browser memory usage is reduced. When a web author specifies <img loading="lazy"> and then the user scrolls the bring the image into view, the image is downloaded and rendered.
  • Firefox now strips the www. prefix in address bar results for improved readability. This behavior matches other browsers.
  • A significant memory leak was fixed in bug 1610193. This leak happened when users reloaded Youtube, Facebook, and possibly other pages.
  • Firefox's about:support information now includes the user's Linux desktop environment. This should make it easier to triage issues that are specific to Gnome, KDE, etc.
  • Firefox now has support for the 'all' value of text-decoration-skip-ink. With text-decoration-skip-ink: auto, ink-skipping is applied to most content, but not to CJK text. text-dectoration-skip-ink: all allows an author to pecify that they actually do want skip-ink behavior to be used with CJK text.
  • The socket process now has Windows Sandboxing. This is part of ongoing work to deliver WebRTC on an isolated process.
  • Firefox now supports CSS conic-gradient with backends for WebRender and Skia. With conic gradients, the colors transition as as if spun around the center of a circle, starting at the top and going clockwise (as compared to a a radial gradient, where the colors transition from the center of a circle, outward, in all directions.)

2020-02-10

I'd like to highlight several items from this latest Firefox meeting that weren't previously mentioned in my Firefox Weekly Update:
  • Support for Fission in DevTools started with enabling the Browser Toolbox to inspect/debug multiple processes. This work is happening behind the pref devtools.browsertoolbox.fission.

• On Friday evening we started receiving feedback that extensions were failing for Firefox users and the Firefox team quickly identified that we had a certificate chain issue. We are extremely sorry to all Firefox users affected by this issue. The TL;DR is that one of the certificates used to authenticate add-ons expired, causing the signatures on all add-ons to break. The fix was to deploy a new certificate to Firefox users. A fix was developed Friday night and initially pushed out to desktop Firefox users through the Normandy infrastructure on Saturday. The fix was rolled out in a full QA'd dot release to both Desktop and Android users on Sunday. There are still some outstanding issues actively being worked on and a list of those unresolved issues can be found in the Firefox 66.0.4 release notes. We will providing a full post mortem on the incident as soon as possible and for now you can also learn more about it at blog dot mozilla dot org slash addons.
• Firefox 67 is in the Beta channel and ships to our stable release a week from tomorrow on May 14th.
• Firefox 68 is in the Nightly channel and ships to our stable release on July 9th. Over the last week there have been approximately 475 bugs resolved as fixed. There was one notable change this week:
  • GetUserMedia now requires secure origins. This brings Firefox in line with Chrome and Safari. See the dev platform post for technical details.

• Firefox 66.0.3 is our currently stable release and came out on April 10th.
• Firefox 67 is in the Beta channel and moves to Stable on May 14th, two weeks from tomorrow. Beta 15 and 16 go out this week. These are our final betas.
• Firefox 68 is in the Nightly channel and ships to Stable on July 9th. 68 is the next ESR base. Next week we begin the Nightly soft code freeze. Last week saw about 500 bug fixes land on Nightly including these notable changes:
  • We've streamlined the "default browser" flow for Fennec and udpated the onboarding. As more users find their way to Fennec as a result of the Android browser choice screen in the EU, we want to make it easier to get started.
  • The new "discovery stream" has landed with a new New Tab layout. The layout moves the snippets up under the search box and includes 4 general interest Recommended by Pocket stories and then 4 stories for each of several categories.
  • Several picture in picture bugs were fixed including hiding the PiP button in fullscreen and hiding the PiP button except on hover.
  • When in "dark mode" Reader View's sidebar/toolbar and controls are now dark too.
  • The Accessibility color contrast auditor is considerably faster on pages with lots of text.
  • Gecko now has support for the Resize Observer API. This API can be used to detect when elements are resized, and run some javascript in response, all between layout & paint.
• From mozilla.dev.platform "Fennec will be following the 68 train to ESR68-based release. We want to provide users with a secure and supported legacy Firefox for Android until Fenix has matured enough for users to migrate to it. Therefore, starting from Gecko 68, we plan to use the ESR68 repository as a stable base for managing Fennec engineering, testing, and release of builds going forward."

• Firefox 68 is in the Nightly channel and ships to our Stable release on July 9th. Over the last week there have been 493 changes landed in Nightly including these notable ones:
  • Firefox now requires user interaction for push notification prompts. This means a site cannot simply pop up the request on page load.

  • A 16 year old Gecko feature request, support for the ::marker pseudo-element on list items was resolved FIXED! the ::marker CSS pseudo-element selects the marker box of a list item, which typically contains a bullet or number. This allows list item markers to be styled or have their content value customized. Thanks, Mats Palmgren (:mats) for the new Gecko feature and Emilio Cobos Álvarez (:emilio) for the code reviews!

2019-03-25

• Firefox 66.0.1 is our current stable release. The new version shipped last week. We had a quick point release for a couple of security issues disclosed at the pwn2own contest. Firefox 66 users are enjoying these new features:
  • Blocking of auto-play media with sound.
  • Scroll anchoring.
  • Basic touchbar support for macOS.
  • Default of 8 content processes up from 4.
  • Redesigned certificate error pages.
  • Support for Windows Hello on Windows 10.
• Firefox 67 is in the Beta channel and moves to the stable release on May 14. Tomorrow the 5th Beta (of 16 planned) goes out.
• Firefox 68 is in the Nightly channel and moves to the stable release on July 9th. Over the last week there have been about 490 bugs resolved as Fixed including these notable changes:
  • We've adjusted the available memory tracker thresholds to minimize out of memory crashes. Now that Firefox can smartly unload tabs when short on memory, we're updating the definition of short on memory to be a bit higher to avoid even more out of memory crashes.
  • The dav1d decoder has been enabled for Linux. Last week it was enabled for Mac and the week before it was enabled for Linux. We now have dav1d decoding on all three of our desktop platforms!
  • We've updated the dav1d decoder to version 0.2.1 for some serious performance improvements. This fixes a couple of crashes and makes decoding about 3 times faster for many users on old CPUs. If all goes well in testing, this update will be pushed to 67 Beta so our users get the perf win even sooner.
  • Another eviltraps bug is squashed. With the changes at Bug 1532338 - Stronger auth dialog abuse enforcement we now make the block apply to the domain of the top-level frame (i.e. what's in the URL bar) instead of the sub-resource, and we reduce the number of allowed cancellations to 2. This should help users encountering evil sites that used the authentication dialog to attack users.
  • Firefox now has an entry point to access saved logins from the main menu providing even easier access to existing saved logins. This change was also uplifted to Beta 67.
  • Firefox now has an avatar toolbar button with menu in the main toolbar for easier discovery of Firefox accounts and Sync capabilities. From the menu, you can quickly access your Firefox account and sent tabs; you can view synced tabs and synced tabs sidebar; and connect to another device, manage your account, and change your sync settings.
  • We have enabled WebRender for a whole class of AMD GPUs. These are the Cayman (Northern Islands) graphics chips release starting in 2010.
  • We fixed a regression causing Office365 PowerPoint text to vanish after typing. This change is being evaluated for uplift to Beta and stable Release. It's a pref flip so should be safe.
  • GeckoView has support for Web App Manifests which is a step along the way to PWA support in Fenix.
  • We now require a user gesture to enable push notifications. This means that a site can't pop up the "want notifications" dialog until a user has interacted with the page. This change applies to desktop Firefoxen as well as Android Firefox.
  • Firefox for ARM64 devices now have Ion JIT support. This applies to both the Windows on Snapdragon laptops as well as Firefox for Android.
  • We now have Live Region support on Android. This accessibility feature allows screen readers to know when content has updated.
  • Firefox on Windows on Snapdragon (ARM64) now supports DRM content like Netflix.
  • Last but not least, we got a nice fix to the Reader Mode from a volunteer contributor. The Reader Mode toolbar no longer zooms when you zoom the content with Ctrl/Cmd + and -.

2019-03-18

• Firefox 65.0.2 is our current stable release.
• Firefox 66 is in the Beta channel and ships to our stable release tomorrow, March 19th.
  • Firefox 66 users will enjoy the new block auto-play feature that blocks media with sound from automatically playing. Users can add exceptions for sites they want to auto-play (gradual roll-out.)
  • We've also got a new feature called scroll-anchoring which prevents the page from jumping up and down as new content loads in while you're scrolling.
  • macOS users will get basic touchbar support.

  • GeckoView allows embedders to load WebExtensions such as content scripts. This may be used by GeckoView apps for features like ad blocking and reader mode.
  • GeckoView now has an API for taking screenshots. This may be used for adding screenshots to the Fenix tabs tray.
  • Push notifications now require a secure context. This brings Firefox in line with Chrome and helps to advance a more secure web.
  • Firefox now syncs the options to block cryptominers and fingerprinters. As we bring new preferences online, we need to sync those preferences.
  • Gecko now has support for capping the maximum life-time of client-side cookies. This is a feature Safari already has and may be useful as sites begin to work around tracker cookie blocking.
  • Firefox now includes an about:compat page which lists active site patches. These are the patches managed by Firefox's webcompat system addon.
  • A 17 year old bug #148794, document.write into iframe adds entries into session history was fixed by BZ's patches at bug 1489308, Align document.open() with overhauled spec. document.open no longer adds session history entries.

2019-01-28

• Firefox 64.02 is our current stable release.
• Firefox 65 is in the Beta channel and moves to Stable tomorrow, January 29th. We're currently in our release candidate (RC) phase so builds on the Beta channel look a lot like release builds in the About Firefox dialog.
• Firefox 66 was is in the Nightly channel last week. (It just flipped over to 67 today.) Over the last week 560 bugs have been resolved including these notable ones:
  • Firefox now has basic support for the Mac Touchbar.
  • The old style system has been removed and we're now using Stylo everywhere.
  • Blocking video auto-play can now be managed from the Control Center. Users can add individual sites to an exceptions list or turn the blocking off from that UI.
  • The crash reporter now supports high DPI scaling so text is no longer blurry there on high DPI setups.
  • The home page in a Private Browsing windows now includes a search field which uses your default search engine.

• Firefox 64.02 is our current stable release. This point release came out on January 9th and addresses several issues including:
  • A browser crash on MacOS
  • Video stuttering on Youtube
• Firefox 65 is in the Beta channel and moves to Stable on January 29th. We're currently in our 10th Beta with Beta 11 coming out tomorrow. We only have 12 Betas planned so we're in the end game now. If you've got bug fixes that need to make Firefox 65, time is short so get those uplift requests in today!
• Firefox 66 is in the Nightly channel and moves to Stable on March 19th. Over the last week there have been 500 bugs resolved as fixed including these notable ones:
  • We implemented Scroll anchoring. As a page is loading, new elements can show up above the scrolled to part of the screen and that causes the page to shift creating a poor user experience. Scroll anchoring attempts to mitigate this and prevent thescreen from shifting when new elements are added above the scroll position.
  • We now have main process crash reporting on ARM64 Windows builds. We don't have content process crash reporting yet. That's being worked on in bug 1517729
  • We also have stub installer support for ARM64 Windows builds. The standard stub installer now recognizes Windows on Snapdragon and downloads and installs the appropriate bits.
  • WebRender has been moved to mozilla-central. Before, WebRender was developed on Github and work was transferred to mozilla-central. Now the canonical home for WebRender is in mozilla-central's gfx/wr directory. WebRender's Github is now a downstream mirror of mozilla-central. This also means that WebRender bugs and patches should be filed in Bugzilla rather than Github.
  • The en-US dictionary got and update and now includes the word "hooptie" among several other additions.
  • Last but not least, a 15 year old layout bug was fixed. The bug, Deeply nested elements are not rendered was fixed by Henri Sivonen (:hsivonen)

2019-01-07

• Firefox 64 is our current stable release.
• Firefox 65 is in the Beta channel and moves to Stable on January 29th. We're currently on our 8th Beta with Beta 9 due out tomorrow. We have 12 Betas scheduled so we're getting into the final quarter. If you've got things that need to make it into 65, time is running short.
• Firefox 66 is in the Nightly channel and moves to stable release on March 19th. It's been three weeks since our last update and in that time we've resolved about 800 bugs including these notable ones:
  • Still behind a flag, we've implemented the dynamic import() proposal. Enabling dynamic import by default is being tracked in bug 1517546.
  • WebExtensions got a clipboard api that supports copying arbitrary strings to the clipboard.
  • Firefox now supports the overflow-block and overflow-inline media queries.
  • A regression that was causing YouTube stuttering (frames dropped) on VP9 videos is now fixed (and uplifted to Beta).
  • We've got "search handoff" on the New Tab Page. So when you start typing in the search box it moves the typing and results to the Awesomebar.
• In addition to all these great changes in Nightly, we've also go the addition of a new platform. We now have untested nightly builds for the Windows on Snapdragon platform. This is Windows running on ARM processors which will become a fully supported platform this year.

2018-12-17

• The Firefox 64 Stable release came out last week. 64 includes the feature recommender, multi-tab operations, a new task manager, and various other features and fixes. Check it out!
  • The ability to select multiple tabs and then move them, re-window them, close them, bookmark, send to device, etc. was a hit with the press, making appearances in the titles of most articles about 64. This feature was made possible because of Google Summer of Code, mentoring from Mozilla's Jared Wein (:jaws) and the hard work of a student named Abdoulaye O. Ly. If you haven't tried this out, it's really cool for reordering tabs, de-cluttering your tab strip, or sending off a group of tabs to your mobile Firefox.
  • You can read more about Firefox 64 at the hacks blog, which covers just about everything you'd want to know about the release, and at MDN which deep dives on changes that web developers and add-on developers will care about.
• Firefox 65 is in the Beta channel and moves to the stable Release on January 29th. If you're on the Beta channel, you're probably using the 4th beta and the 5th beta is due tomorrow. Over the last week, we've uplifted about 40 bugs to Beta, including several crash fixes, enabling the AV1 video format, and fixing selection color visibility on dark backgrounds on macOS
• Firefox 66 is in the Nightly channel and moves to the Stable release on March 19th. Over the last two weeks we've resolved about 600 issues including these notable ones:
  • Use level 1 headings for major groups in Preferences This makes our accessibility in Preferences better. (Fixed before the uplift so present in 65)
  • Add a new error page for MOZILLA_PKIX_ERROR_MITM_DETECTED This means some of the people who have their browser connection completely broken by AV and other third party software will get a warning that actually explains to them what's going on. (Fixed before the uplift so present in 65)
  • Implement win/osx sandboxing for new RDD process RDD is Remote Data Decoder which is the new process for media used by AV1 and soon other formats. It's now sandboxed on Windows and macOS (Fixed before the uplift so present in 65)
  • Last but not least 17 year old bug 167475 Disable external and returning no data protocol handlers in all cases, excluding <A HREF=> was fixed. From the patch "This is done in order to block external protocol URLs in iframes, which cannot be used to create documents, and they could exec external apps or show prompt dialogs."

The second version, launched last Wednesday, will give you an alert right in Firefox when you visit a website that's had a breach in the last 12 months. We've also increased Firefox Monitor's global reach by expanding it to 26 languages. Congratulations to the Firefox Monitor team and all the amazing volunteers that helped localize into so many languages.
