Summary - Firefox crashes repeatedly. yesterday, I decided to switch to Firefox after using Chrome for a while. it worked fine and I synced my data from Chrome. today, at some point I noticed Firefox is no longer open in my taskbar. I decided to reopen it - it crashed. since that moment it has never worked again. I tried launching it in safe mode (firefox.exe -safe-mode), didn't work. tried reinstalling it, didn't work. manually deleted the files from C:\Program Files and AppData, installed Firefox again, didn't work. reinstalled gpu drivers, didn't work. sfc /scannow-ed, you guessed it - still crashes. what else could I possibly try? please help.

p.s. this was posted through an android phone but the problem only occurs on windows

When testing our web application, I can consistently get the tab to crash in Firefox (not other browsers). This happens even when running in Troubleshoot mode.

A few of the submitted crashes: bp-f1e47e32-aa7e-4080-880c-34f160250710 bp-622b9363-fa50-4b15-b605-87c3e0250702

Can anyone tell what is causing it to crash, and if we can do something to fix it?

Why would you cancel coverage on FakeSpot? This was a tool used frequently by multiple people that I knew, and what it really feels like is that FireFox is being bought out and removing it to make it easier for all of the scammers to continue to pump us full of fake garbage. Really disappointing to see this service being discontinued and hoping that you reconsider.

Hello! I've been seeing some strange behavior on firefox launch or on new profile launch. There is a popup during startup, can't see it on the screen but I can see it in tray. Is this normal or no? I observed it on two different hp notebooks so far.

I have created several groups (currently 4 with a total of 11 tabs combined). When a group is closed, do those tabs become inactive, reducing their impact on Firefox/computer performance, or do they still remain active and impacting overall performance?

As creator of retroonline.net. We recently noticed Firefox have limited value size in IDB which Chrome and Edge do not have. This limitation prevents big games running on Firefox despite Firefox has the best performance on WASM. Will there be a proper way to change this limitation or plan to remove it?

Hi,

Whenever I try to watch videos on Anime Slayer APK in Firefox, I get a message saying the browser is “unsupported” or the video just won’t play. I’m using the latest version of Firefox on Windows, and I’ve already cleared my cache and disabled extensions, but the issue persists.

Interestingly, the same videos work fine in Chrome and Edge — so it seems like a Firefox-specific problem.

Is there some setting or add-on I need to enable to make it work? Or is this a known compatibility issue with certain websites?

Thanks for any help you can provide — I’d rather not switch browsers if I can avoid it.

I was planning to start using the AI chatbot sidebar finally, tried out all of the free options available and settled on HuggingChat. The very next day, HuggingChat ceased operations. I don't really like the other preset options, but I have a couple of other models that I would be interested in trying out. Is there some way to add a different model than the five preset or am I just out of luck?

After exporting bookmarks.html from Ffox on old computer, importing it to Ffox on the new one, all good, except that bookmarks toolbar shows on the imported list but doesn't display as toolbar.
