And again,
https://ftp.mozilla.org/pub/firefox/releases/145.0.2/

With release notes:
https://www.firefox.com/en-US/firefox/1 ... easenotes/

Fixed an issue that prevented typing in Baidu’s search box when using Chinese IMEs on Windows. (Bug 2000479)

On Windows, clicking tabs may not work at the very top of the screen when Firefox is maximized on a second monitor. We’re working to fix this in a future release.

Absolutely nothing for us. I need to test a build anyway though (new LLVM build since then), I'd been waiting for a point release.

Posted: **Wed Nov 26, 2025 12:11 am**

My Firefox 145.0.2 build actually failed, the first (profile gen.) result wouldn't run correctly for profiling (aborted on illegal operations). It looked like javascript was involved, so I took a guess that my node.js was too old (it runs javascript to generate things during the build). So I upgraded node to the latest LTS, v24.11.1 and that solved it. That was rather unexpected for a point release, I'll bet it's something they did while fixing that Baidu with Chinese input issue on Windows (they may not have upgraded their node mid cycle, they just used something that mine was too old for)

Firefox 146.0 is in the directory now
https://ftp.mozilla.org/pub/firefox/releases/146.0/

No release notes yet.

P.S. From reading around, it seems the only significant new feature added for Linux is fractional display scaling on Wayland. I don't give one fractional nanofuck about that.

P.P.S. Formal release notes now:
https://www.firefox.com/en-US/firefox/1 ... easenotes/

Windows 10 users can now automatically protect their passwords, bookmarks, and more by turning on backup in Firefox. Your browsing data is saved daily on your device and can be encrypted with a password. When you set up a fresh install of Firefox on any operating system for a new device or your current one, you can restore from this backup and pick up right where you left off. This feature is currently available on Windows devices and will be coming to other operating systems soon.

MacOS users now have a dedicated GPU process by default. This includes WebGPU, WebGL, and Firefox's own WebRender. With this feature enabled, fatal errors in graphics code will no longer crash the browser, and will instead transparently restart the GPU process.

Firefox Labs is now available to all desktop users, regardless of whether they choose to participate in studies or submit telemetry. This means more experimental features are now available to more people.

Users can now skip the results page and see direct results as they type in the search bar for faster, simpler browsing.

There is a New Tab Weather opt-in workflow available for users in the EU and some other countries, where they can choose whether to enable location detection or manually search for a location.

Firefox now natively supports fractional scaled displays on Linux (Wayland), making rendering more effective.

For users of the English-language versions of Firefox in France, Germany, and Italy, the address bar now shows English-language suggestions for holidays and other important dates.

When the timepicker is enabled for <input type="time"> and <input type="datetime-local">, it now provides full keyboard and assistive technology support. This update also improves the behavior of the time spin buttons for users who prefer reduced motion. The Firefox Accessibility team hopes that making the built-in timepicker accessible will encourage wider adoption of browser-provided time and date inputs across the web, reducing the need for custom controls, and improving accessibility for all users.

Various security fixes.

This:

CVE-2025-14322: Sandbox escape due to incorrect boundary conditions in the Graphics: CanvasWebGL component

I've been sick of seeing seccomp sandbox violation warnings on my console for the last 2 release cycles. I'm glad that's fixed now.

Also, they've locked users out of reading bug reports. It needs a login now, so I can't even read those like I used to. I'm not jumping through hoops.

Posted: **Fri Dec 19, 2025 12:56 am**

It's been a while for 146.0 but eventually there's going to be a 146.0.1 and that eventuality is today.

Release Notes!
https://www.firefox.com/en-US/firefox/1 ... easenotes/

Improved overall stability by fixing crashes related to browsing, graphics, and accessibility features. (Bugs 2001160, 1998185, 1998188)

Fixed an issue where fingerprinting protection caused incorrect font rendering on popular websites. (Bug 2000429)

Fixed crashes related to media playback and GMP process shutdown. (Bug 2002697)

Fixed an issue where desktop profile shortcuts were being unintentionally removed when changing copied profile settings. (Bug 1998209)

Improved sidebar text contrast when using vertical tabs with certain themes. (Bug 2006091)

When restoring from a backup, the restore success message will appear over the new tab page instead of one of the tabs restored from a backup, to avoid cases where the restored tab canceled the restore success message. (Bug 2003307)

Firefox 147.0 is in the directory today:
https://ftp.mozilla.org/pub/firefox/releases/147.0/

No release notes, but we know it's set to put configuration in ~/.config/mozilla according to XDG specs. Also I heard something about "zero copy" video decoding. I guess that means not only is it GPU accelerated, the operation takes place in VRAM. I don't know what codecs will be using that in Firefox.

P.S. Release Notes:

Fixed an issue that could lead to sites being incorrectly flagged as malicious by SafeBrowsing. (Bug 2010956)

Various security fixes.

Adding a new experimental feature in a point release, tsk tsk.

There's a Firefox 147.0.3 now, for whatever reason (no release notes yet).

https://ftp.mozilla.org/pub/firefox/releases/147.0.3/

I guess I'll just do it and see later.

P.S. 147.0.3 Release Notes:
https://www.firefox.com/en-US/firefox/1 ... easenotes/

New

Interoperability improvements for the CSS anchor positioning and Navigation web APIs.

Fixed

Fixed a regression where position: sticky elements on some webpages could appear stuck or fail to update while mousewheel-scrolling after certain :hover interactions. (Bug 2010481)

Fixed an issue where the Firefox Developer Tools could fail to re-open after using the Inspector’s node picker and reloading a page containing cross-origin iframes. (Bug 2003810)

Fixed an issue where the DNS over HTTPS provider settings section could appear as a blank box, preventing users from seeing the current setting or changing it. (Bug 2010501)

Fixed an issue on Windows systems with a large number of fonts installed where parts of the Firefox UI (tabs, menus, and Settings) could display garbled characters or symbols instead of readable text. (Bug 2012950)

Posted: **Mon Feb 16, 2026 11:18 pm**

Firefox 147.0.4 now with a security fix <---

https://www.firefox.com/en-US/firefox/1 ... easenotes/

Fixed an issue that could cause the New Tab Page to appear blank for some users. (Bug 2014616)

CVE-2026-2447: Heap buffer overflow in libvpx

I'm not doing this, because Firefox 148.0 will be out very soon. I was surprised to see this nonsense instead. I guess they have to fix things like those right away, but I'm getting sick of this shit, I haven't even finished fighting with Arch yet today and I've got to get on the bot detail again too.

Posted: **Tue Feb 17, 2026 7:57 am**

I decided to start a build before going upstairs and found that... I couldn't. It it was failing to build a glsloptimizer crate, and the trail of "file included from" led to glibc includes in /usr/include/bits and stuff (pthread related). That means glibc 2.43 fucked that up.

I was relieved it was that though, because it meant there would be a patch. Sure enough, Arch has one "0003-Patch-glsl-optimizer-to-build-with-glibc-2.43.patch" that I'll have to work into my scripts somewhere.

It's probably a good thing I tested this tonight, however, I could have stood to remain blissfully ignorant for the night at least (because once I know something is broke, I have to fix it).

Posted: **Mon Feb 23, 2026 8:27 pm**

Firefox 148.0 today, but no release notes yet.

https://ftp.mozilla.org/pub/firefox/releases/148.0/

P.S. It's fucking pathetic (well, more irksome than pitiable), that a new release cycle still won't compile against the current glibc on Linux. What, do they expect everyone to hold back until queen firefox is good and ready?

At least the patch still works. Good thing, because it's not one I can fix. It's a complex "git" patch that kind of fast forwards the state of the files and renames them. Not something I can edit and diff to make a new one. (and it's hundreds of files that use those definitions incorrectly). They just want to keep sewing more arms onto the octopus.

(Funny how with all the things I've compiled, on both OSes, since bootstrapping with glibc 2.43, only this uses such definitions incorrectly. Trial and error programming rather than good practices?)

A Firefox redesign is in the works, called Nova

Mozilla is working on a huge redesign for Firefox, internally named "Nova," featuring strong curves that aggressively round off the tabs and the address bar, pastel colors, a refreshed new tab page, floating "island" UI elements, and more.

Sören Hentzschel, a web developer and author of several open-source extensions, shared these early mockups, but the final app could end up looking pretty different since actual development has only just started.

From the mockups, it appears Mozilla took some inspiration from Google's Material You (or at least, the dynamic color extraction part of it) because the browser color accent appears influenced by the wallpaper setting. Choosing a mint-green desktop background automatically shifts the top navigation bars to match that exact shade.

Firefox 148.0.2 today (they've skipped .0.1) but no release notes. I was going to do a toolchain test build today anyway, so that's good. (new Rust 1.94)

P.S. Firefox 148.0.2 Release notes. Purple release notes, even lol

https://www.firefox.com/en-US/firefox/1 ... easenotes/

Fixed

Fixed an issue where searches entered in the Firefox Home search field were incorrectly redirected to the address bar for some users who had disabled search handoff behavior via advanced settings. (Bug 2017049)

Fixed an issue where some web-based rich text editors stopped applying formatting, such as bold or italic. (Bug 2020927)

Fixed an issue where videos could autoplay unexpectedly on YouTube despite autoplay being blocked, particularly impacting screen reader users. (Bug 2020233)

Fixed an issue that caused some absolutely positioned elements meant to be centered, for example, using margin: auto with inset: 0, to appear left-aligned on initial load. (Bug 2017440)

Fixed an issue where the “Switch to Tab” suggestion in the address bar appeared blank for pages without a title. (Bug 2020341)

Fixed an issue that could reduce video quality on Windows systems using NVIDIA GPUs with Video Super Resolution enabled. (Bug 2019515)

Various security fixes.

Firefox 149.0 today.
https://ftp.mozilla.org/pub/firefox/releases/149.0/

I don't know what's in it, but gotta have it

They still haven't fixed it to build with LLVM 22 (patches still needed)

P.S. Probably the most significant change for Linux that I heard about, is that it defaults to the XDG Desktop Portal file chooser instead of GTK (fallback now). I fucking hate that flatpak sandboxing garbage and I'm glad I don't have it installed. I don't need training wheels or anyone's permission to access my file system, thanks. I also would not like the inconsistency (e.g. if using an xdg-desktop-portal for a different desktop, firefox is going to use a different file manager back end) if that actually applied to me. It doesn't, only because I don't let such things get installed.

The enshitification of our software environment continues...

P.S. Release Notes
https://www.firefox.com/en-US/firefox/1 ... easenotes/

Split Views
Built in VPN (50 Gb/month free)
More, cutesy nannying
XDG portal file choosers on Linux

Firefox 149.0.2 (they skipped .0.1)
https://ftp.mozilla.org/pub/firefox/releases/149.0.2/

No idea what's in it yet

Posted: **Mon Apr 20, 2026 7:23 pm**

Firefox 150.0 is here today:
https://ftp.mozilla.org/pub/firefox/releases/150.0/

Of course they'd never have release notes ready at the same time, because they have to make fancy purple pages. (I'd have a text file in the source dir first, web page later, or auto-generated from that file but it's too promotional for that)

Well, let's see if this release cycle builds out of the box with LLVM 22.x and Rust 1.95

P.S. Fuh Koff... they still haven't fixed this -Werror=deprecated horseshit (put in a condition check for the conf test to accommodate newer and older LLVM wasi target or simply -Wno-deprecated if they must use -Werror for that conf test... it would take 2 seconds to fix)

Code: Select all

 0:06.99 DEBUG: | clang: error: argument '--target=wasm32-wasi' is deprecated, use --target=wasm32-wasip1 instead [-Werror,-Wdeprecated]
 0:06.99 E ERROR: Can't find clock() in wasi sysroot.
 0:07.05 E *** Fix above errors and then restart with "./mach build"

That probably means the LLVM 22 related failures are still going to need patches. I'll have to see what happens as I go, and if the patches are still appropriate.

Note: The LLVM 22 patches are still necessary, but the glibc 2.43 patch is no longer necessary (not appropriate... already fixed and fails to apply)

Release notes for Firefox 150.0
https://www.firefox.com/en-US/firefox/1 ... easenotes/

Split View just got better: You can now right-click any link and choose Open Link in Split View to open it alongside your current tab. You can also search open tabs when creating a split view and quickly reverse tab positions using the new Reverse Tabs option in the tab context menu.

Share multiple tabs in a single step: select several tabs, right-click, and choose Share → Copy X links. When pasted into other apps, links include both the page title and URL for easy reading.

You can now use Firefox’s built-in PDF editor to reorder, copy, paste, delete, and export pages in a PDF.

Try out real-time, private translations in Firefox Desktop with the about:translations page. Start typing the word "translate" into the URL bar for a quick-action shortcut to the page.

Added support for the GTK emoji picker on Linux, allowing users to insert emoji using the system shortcut (typically Ctrl+.).

Firefox web apps are now available to Windows users who installed Firefox through the Microsoft Store.

The new Firefox Profile management system is now available to all users, including users on Windows 10.

Backing up a profile to a file is now available to all Windows 10 and 11 users, including those who use the new profile management system.

Firefox now ships with a new .rpm package for Linux users on Red Hat, Fedora, openSUSE, and other RPM-based distributions.

The built-in VPN is now available for users in Canada. Note: This feature is not available in enterprise environments.
Currently available in: Canada, France, Germany, United Kingdom, United States

Fixed an issue on macOS where, when macOS Lockdown mode is enabled, emoji characters are not displayed in web content

Various security fixes.

If you prefer creating tab groups from the context menu, you can now turn off drag-and-drop group creation in Settings > Tabs > Drag tabs to create tab groups.

Pretty major release number, but there's nothing really earth shaking here. It's a lot of incremental upgrades, enabling things outside of testing regions/OS environments etc. and a long list of security fixes.

Posted: **Wed Apr 22, 2026 6:24 am**

So just like kernel 7.0.0

Posted: **Wed Apr 22, 2026 6:42 am**

I like projects that have been version 0.something for 20 years

In software, a major version change like that used to signify major changes, even breakage for a particular purpose (i.e. would require testing).

There wasn't even that much stuff to say N to, with oldconfig. It probably would have been more appropriate for it to have been 6.20 but it doesn't matter, if it makes someone happy.

Posted: **Mon Apr 27, 2026 11:02 pm**

... and now it's at 150.0.1 just like any normal release cycle
https://ftp.mozilla.org/pub/firefox/releases/150.0.1/

No purple release notes yet, of course.

P.S. Purple release notes:
https://www.firefox.com/en-US/firefox/1 ... easenotes/

Fixed an issue where Facebook and other websites might not load properly for users with Bitdefender security software installed. (Bug 2034178)

Fixed an issue where denying a geolocation permission prompt could cause Firefox to show the system permission dialog again on a second attempt. (Bug 2034120)

Fixed an issue that prevented tabs from being added to some older saved tab groups. (Bug 2031961)

Fixed a layout issue where some drop-down menus expanded to display all list items at once. (Bug 2033117)

Fixed an issue where borders and outlines on some page elements disappeared when pinch zooming or smart zooming on macOS and Windows. (Bug 2030043)

Various security fixes.

Changed

All Relay users can now create up to 50 email masks—an increase from the previous limit of 5.

I heard that Firefox integrated Brave browser's ad blocker.

Posted: **Tue Apr 28, 2026 9:44 am**

Wow, hidden, I didn't know. It doesn't matter, I'd prefer it to be disabled because I doubt that by any stretch, it's going to be as effective as Ublock Origin (especially with custom filter lists added). My guess is that they will want to allow some ads.

They have killed their own golden goose, sites that want ad revenue. Some sites where you go to read articles are so bad with skyscraper sized ads on the left and right, top and bottom and it's almost like you'll be lucky to be able to find the strip of text you came to read. So fuck them, ad blocking is becoming the norm.

It was even more horrible back when sites that had ads that loaded plugins (e.g. flash) for "rich content ads" would be more likely to crash your browser than interest you.

Posted: **Wed May 06, 2026 7:14 pm**

Firefox 150.0.2
https://ftp.mozilla.org/pub/firefox/releases/150.0.2/

No release notes yet. I'll edit and paste when they are available as usual.

Posted: **Wed May 06, 2026 8:41 pm**

Well, strike 1. It reset the bookmark toolbar setting to "always show". I hate that toolbar, I don't even use bookmarks.

That means I have to go through all the settings and make sure nothing else has been messed with.

P.S. Everything else seems to be OK, nothing else was reverted to default.
