    • This feature is currently disabled by default. Set signon.management.page.vulnerable-passwords.enabled = true in about:config to enable it.

2020-03-23

• Firefox 74.0 is our latest stable release.
  • To avoid any extra work for sites during this time of corona virus, we've updated Firefox to no longer disable TLS 1.0.
• Firefox 75 is in the Beta channel and it goes to our stable release audience on Tuesday, April 7th. This the third and final week of betas for this cycle and next week is RC week.
• Firefox 76 is in the Nightly channel. 76 is due to hit our stable release channel Tuesday May 5th. Over the last week there have been over 470 fixes landed in Nightly including these notable fixes.
  • Firefox no longer supports allowing web developers to control toolbars (tabbar, menubar, toolbar, personalbar) in pop-up windows. (bug 1507375)
  • WebRender is now enabled for Windows 10 Intel laptops with medium resolution screens. (bug 1622959) WebRender was previously enabled for Win10 Intel laptops with 1900x1200 or smaller resolution and now it's enabled also for 3440x1440 and smaller.
  • Disabled form controls are now selectable. (bug 253870) 🎉🥳 16 year old bug fixed! 🥳🎉

  • Firefox Nightly now uses the Dav1d 0.6.0 version which brings major improvements in 10/12bit decoding on ARMv8 CPUs, up to 2.5 times faster than 0.5.2. It also brings new AVX-512, AVX2 and SSSE3 optimizations and improves the existing optimizations on all platforms. Finally, it also fixes some decoder mismatches and minor crashes.

Just a reminder, in this new four week cycle, we have three weeks of three betas, then RC week, then release.
• Firefox 76 is in the Nightly channel. 76 is due to hit our stable release channel Tuesday May 5th. Over the last week there have been over 400 fixes landed in Nightly including these fixes I thought were worth mentioning.

  • Easy importing of bookmarks and history from the new Microsoft Edge browser on Windows and Mac.
  • Add-ons installed by external applications can now be removed using the Add-ons Manager and going forward, only users can install add-ons; they cannot be installed by an application.
• Firefox 75 was in the Nightly channel this last week. Firefox 75 hits our stable release audience on April 7th. Today is Merge Day and Nightly just became version 76. Over the last week there have been about 440 bugs resolved as Fixed including these notable changes:

2020-03-02

• Firefox 73.0.1 is our current stable release.
• Firefox 74 is in the Beta channel. We're three weeks in to a four week Beta cycle and this final week is RC week. Next Tuesday, 74 goes out to our stable release audience.
• Firefox 75 is in the Nightly channel. This Wednesday is "feature complete", Thursday is the "soft code freeze", and Friday is the string freeze. Firefox 75 will move to the Beta channel a week from today and ships to our stable Release audience on April 7th. Over the last week there have been about 400 bugs resolved as Fixed including these notable ones:
  • A longstanding PDF printing bug has been fixed.
  • Firefox now applies prefers-color-scheme: dark to top-level about:blank pages which prevents a flash of light when using the dark theme.
  • CSS min() / max() / clamp() functions are now supported by default.
  • Gecko now has a prototype of :focus-visible behind the flag layout.css.focus-visible.enabled.
  • Cookies sameSite=lax has been enabled by default.

2020-02-24

• 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. So far, the Beta contains changes to support importing profile data from Edgium on Windows and Mac, the OS compositor has been enabled for macOS when WebRender is enabled, TLS 1.0 and TLS 1.1 have been disabled, and Dev Tools has a new Application panel where Service Workers and Web App Manifests can be easily inspected.
• Firefox 75 is in the Nightly channel. This is our first 4 week Nightly cycle. Our feature complete milestone for this Nightly cycle is next Wednesday March 4th; the soft code freeze on Thursday March 5th; and string freeze on Friday March 6th. 75 moves to the Beta channel on March 9th and becomes the stable release about a month later on April 7th. 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

• Firefox 66.0.2 is our currently stable release. This second dot release shipped last Wednesday to fix a web compatibility issues with Office 365, iCloud and IBM WebMail caused by recent changes to the handling of keyboard events (Bug 1538966)
• Firefox 67 is in the Beta channel and moves to the stable release on May 14th. Beta 7 and 8 (of 16 planned) ship this week so we're coming up on the half way mark for this cycle. Over the last week we've uplifted about 60 fixes to the Beta channel including the new Accounts toolbar button.
• Firefox 68 is in the Nightly channel and ships to the stable release on July 9th. Over the last week there have been 525 fixes landed on Nightly including these notable changes:
  • We fixed a regression where Windows Preview per Tab was broken (and uplifted the fix to Beta.)
  • (Device Pairing Phase 1) Desktop Auth was enabled for pairing the Reference Browser to Desktop using the QR code experience. (This has also been uplifted to Beta.)
  • 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.

• 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 -.

• 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.

  • We've added an "import" option to the file menu to make browser migration more discoverable.

  • 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.

There's an updated Language section in Preferences where it's easy to install multiple language packs and order language preferences for Firefox and websites. And, in Firefox 65, you have a revamped Task Manager, found at about:performance that, along with energy usage now reports memory usage for your tabs and add-ons.
• Firefox 66 is in the Beta channel and moves to Stable on March 19th. Beta 7 is due out tomorrow. If all goes well with testing, Firefox 66 is going to deliver tracking protection enabled by default for a percentage of users, and blocking of video autoplay for all users.

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.

• 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)

• 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).

• 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.
• And if that wasn't enough, last week we also launched Price Wise in Test Pilot in time for the holiday gift buying season.

The browser's JS debugger can be used to inspect and control the replay. This is Mac-only for now.

Instead of tabbing through the tabs on your tab strip in that order, you'll get a pop-up with tiles for the the most recently used 6 tabs. This more closely mirrors the operating system's window switching interface.
