Firefox Desktop (x64) worked normally until the version 135 update was installed. Now tabs (even a single tab) crash after startup unless Firefox is run in troubleshooting mode or Windows 8 compatibility mode. OS is Windows 10 Pro (x64) 22H2 on ThinkPad E495 (AMD Ryzen 5 3500U) Things that haven't resolved the problem: - Remove extensions and themes - Refresh Firefox - Reinstall Firefox - Updating Visual C++ 2015-2022 with Redistributable (x64) version 14.42.34438 - Updating Firefox to version 135.0.1 and subsequently to version 136.0, however updater only works in Windows 8 compatibility mode - Full system scan for malware (none found) Note: Extensions NoScript and Cookie AutoDelete work normally with Firefox running in Windows 8 compatibility mode.

Hello,

We ran in-place upgrade from Windows 10 to Windows 11 on a number of machines. Afterwards, web sites like citibank.com or linkedin.com crash as soon as the page is loaded.

We've uninstalled/reinstalled Firefox, deleted all data, nothing worked.

Anyone else experience this problem? Is there a fix?

Thank you!

Firefox can't seem to be able to import from Vivaldi. Whether I try, it just always takes on and on until it crashes. I remember it working whenever I tried to import browser data before trying to import from Vivaldi to Firefox.

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

Hi, I just installed the latest update (I think it's 136.0.2). I guess I skipped some/several versions. Suddenly my main menu isn't workin anymore (clicking it with the mouse, that is) There is some overlay which I can't find out, how to remove. Even the Minimize/Maximize/Close buttons don't have any function. Luckily I can still access the menu via keyboard shortcuts. How can I remove that overlay bar ... or did I catch some malware ?

hi, i genuinely have no idea why this is happening because it started crashing all of a sudden and it doesnt happen mid-use, i cant use it at all and restarting firefox just results in another crash and so on. what am i supposed to do??

When attempting to attach file to enail from File Explorer, or do a "Save as" of a photo, Firefox crashes and a "Firefox Crash Reporter" box appears, which instructs me to restart Firefox.

My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

We're finding we can no longer watch FUBO TV on Firefox. Works fine in Edge. Anyone have any suggestions? We've cleared cache/history, restarted laptop, etc. This occurs both on recorded programs and live tv. We still seem to be able to get the commercials, although we tried watching on two different devices and the commercials were very different. Is it possible for Firefox to have been hacked but not Edge on the same device? Doesn't sound plausible to me, but I'm not sure. This has happened since the last update to Firefox. We have Windows 10 64 bit. Firefox 134.0.2 or whatever the latest version is. We're stumped why it works on one browser but not the other. Has to be a Firefox issue.
