A (supposed) Firefox update on my computer at 13:00 Tuesday 8th January AEST crashed and eliminated all my open tabs and all of my Bookmarks. The update was unusual - Firefox usually does it's updates when you start using it. This time I was using Firefox doing multiple things and boom, request for an update then collapse. Did anyone else have this problem? Does anyone know why such a catastrophic event might have happened.

134.0.x has seemingly brought in a conflict in the system. When I have Firefox open, the mouse becomes jumpy, the keyboard is often interrupted, and if any music is playing on the system, it becomes a buzzing sound. This buzzing is coincident with the keyboard and mouse issues. I have added no new software or hardware to the system, a Windows 10 desktop. This update has forced me to revert to Edge if I have any need to write, use the mouse, play a YouTube video. Thank you.

Endless crashes, going on for months (4-5) and no sign of any fixes. As far as I'm concerned, Firefox is totally broken and I'll have to switch away. It's unusable. A crash every ten minutes.

I had Firefox installed and working perfectly fine , but I had to factory rest my MSI laptop (windows 11 home) because I had suspect suspicious files I needed to get rid of, after the new install of Firefox each time I try to sign into a google account I would be able to type 2/3 letters and then Firefox crashes and closes down , I had uninstall and downloaded a fresh install from the microsoft store

There's a problem with video playback on firefox, where after a while/randomly, the thing happens as shown in the image. I've uninstalled intel graphics driver and reinstall, didn't work, I've refreshed firefox, didn't work, I've fully uninstalled firefox and reinstall, didn't work, and when the error occurs the igpu is at 100% usage (and ram/vram usage is not full). The whole firefox app will be laggy but not windows, and upon pausing the video only will firefox be free of lag, and a refresh will solve the issue. However, it will occur again once in a while, doesn't matter the resolution or volume, and not just youtube but all other video players. It does occur more frequently and predictably when the video is paused for some time, or when the computer sleeps for a while, and I think it has something to do with the way firefox handles ram. (just my guess)

The only fix that worked was setting media.wmf.dxva.d3d11.enabled to false, which is undesirable as it increases cpu usage by at least 20% as well as increasing my battery discharge. Other fix includes using other browsers, using my nvidia rtx on firefox, and (not totally sure) setting the resolution lower.

Also, after the error occurs/before the error occurs, firefox doesn't do that blink-in-blink-out animation when going fullscreen on video players (like chrome), which can be fixed by exiting the firefox application completely and restarting it. Refresh doesn't work here.

Hello. I often use a frame interpolation application called Lossless scaling (LS) for watching YouTube videos. LS captures frames from a window using APIs like DXGI or WGC and generates interpolated frames between them. When running LS with YouTube videos played in full-screen on other browsers, it correctly detects and operates at the video's native framerate. However, when using Firefox, the application detects a framerate 2 to 3 fps higher than the actual video fps. For instance, a 60 FPS video is detected as 62 FPS, resulting in poor frame pacing and a noticeably choppy playback. It works fine in Chrome or Edge, but I would really like to resolve this issue.

Since updating Thunderbird crashes shortly after starting or sooner if I initiate an update check. If I pull the internet connection and the update check fails it doesn't crash.
