In my org - ever since the release of Firefox 146 - each time an update is rolled out on a WIndows 11 endpoint - Firefox is no longer able to launch.

This is resolved by uninstalling and reinstalling the client. We've had no issues with the ESR release in my testing.

What changed? Anyone else experiencing this?

I had our security team take a look at the antivirus - they've confirmed we aren't blocking Firefox and they did not see any block reports.

No relevant policy changes have gone through around the time of the incident. Initially I suspected users were installing Firefox ESR from the Company Portal alongside the standard release - but confirmed this is not the case. Also ruled out browser extensions - error persisted across a config without any extensions.

Please let me know if there is troubleshooting info I can collect. I included info from my own browser, but I reinstalled on the 27th and it has been working since. However, it has broke specifically on the days new releases have come out.

Thank you for any suggestions!

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

How do you avoid/deal with Firefox website incompatibilities? This happened on consecutive visits to two different websites today before I posted here.

In the first one, I disabled Ublock, cleared cache and cookies, and the site loaded, I then enabled Ublock with no error prompted.

Then I got a tab crash on Youtube. I wouldn't call tab crashes a daily occurrence for me, but I'm accustomed to them

Gmail tab crash just now. It just happened now with another website tab crash. i'm reverting back to 147.01

Is there any way to get the root of this. The only recent changes I can think of are browser (147.0.2 yesterday) and addon updates. Should I post my list of addons?

You started pushing a widget a while back that shows the days I've been on Yahoo, concurrent and otherwise. This thing is annoying and I want it gone. I don't care how much I've used Yahoo on my devices and You already know via tracking cookies.

Make it go away or tell me how to get rid of it - PLEASE.

Interacting With / Clicking On / Click On Any Extension Crashes Linux Firefox | 147.0.2 (64-bit) Debian 12 Gnome Wayland

NB - For the past half a year I have to sometimes right click to interact with them, anyway

Effectively, I will interact with the extension at the most basic, normal level on something that has interactive elements like a dropdown menu, or basic options.

I will click / right click on the icon and the highlight will appear, then that's it ... the browser then crashes and does not recover. :(

What's worse is that I have to Force Quit and when I restart there is no crash report to send to Moz.

I am just wondering if other Linux users have experienced similar issues.

The attached image is taken at the moment before the 'Force Quit' dialogue opens up in Debian 12 Gnome (Wayland) ...



I have Hardware Acceleration on.

I am about to start testing with it off, but I work from the browser, and do not want performance compromises. So that is (at best) a work-around, and certainly is not a fix.

I'm on version 147.0.2 (64-bit) which would appear to be from the Mozilla Firefox Debian Package mozilla-deb - 1.0 install/repo/whatever ... and the PC specs are: Processor: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Memory: 32705MB (11893MB used) Resolution: 7680x2358 pixels OpenGL Renderer: Quadro RTX 3000/PCIe/SSE2

These are my media. prefs ... but ... I doubt that it is relevant: media.ffmpeg.allow-openh264 true media.ffmpeg.customized-buffer-allocation true media.ffmpeg.disable-software-fallback false media.ffmpeg.enabled true media.ffmpeg.encoder.cpu-used 7 media.ffmpeg.encoder.enabled true media.ffmpeg.encoder.quantizer-max 35 media.ffmpeg.encoder.quantizer-min 10 media.ffmpeg.vaapi.force-surface-zero-copy 2
