Which, you know, kinda makes a web browser pretty unusable. And I don't want to lose all my tabs, as I have probably hundreds. None of the topic choices really fit.

Android 7, stationärer Medienplayer Firefox Nigthly 138.0a1

Crash at: manual login to websites, (automatic login via Cookies works) open Settings>Passwords>Saved passwords. Crash is independent of the nightly version.

Since I upgraded to the latest version, Firefox is sluggish and crashes on a regular basis. I have changed my privacy settings from strict to default, has not changed the problem. How can I go back to old version? I choose Firefox because of the privacy concerns, and understand that some websites won't work well, but I've never experienced consistent problems with the app crashing.

Since version 134 of Firefox Android has been out, it crashes EVERY TIME when I try ot use the "back" gesture on my Xiaomi 14(i.e. swiping from right or left side of the screen) I tried Firefox 134, Iceraven 2.27 (also based on the same Gecko) - they act the same. In the same time I also have Waterfox, based in the previous version of Firefox 133, and it responds properly. I guess it is related to the latest version only. Here's the crash log:

Recently, I've had an issue with your browser on my desktop. I use AOL for my homepage. When I open the browser, it takes a long time to load. When it finally does, sometimes the tab crashes immediately. If it doesn't, I try to open another tab and that will crash. I don't have the problem when I use Edge. Any suggestions? If I remove Firefox and reinstall it, will I get all my favorites back?.

I'm getting a lot of crashes lately. I've restarted my phone, force closed Firefox and deleted the cache. Didn't fix it unfortunately. Firefox Android Mobile 134.0.2 (Build #2016068999)

It is what it sounds like. Just merely switching to it crashes it. Previously I was struck on Private mode but after reinstalling, I'm now struck on normal mode. Don't know if it's a bug or whatever but it is what it is. It noticed this around a week ago but don't know it was there even before that. Last time I left it on Private and didn't switch but when I went to switch Last week, it crashed.

Hello. I recently found an issue with Firefox Nightly for Android crashing upon pressing a volume key.

I haven't fully explored the bug yet, but currently, I have found that on YouTube, it will crash consistently. I can report later if it'll crash on another site.

Any thoughts? I don't get an error message, so I can't narrow it at all.
