Firefox refuses to open completely
I uninstalled firefox completely including the profile folders from both the local and roaming locations, I've tried starting in safe mode/troubleshooting mode. All it does when I try opening is flash the window for half a second. In task manager it pops up for half a second, I can't even check the properties, cancel the process tree, etc. Even worse: there is no crash reports/files.
Firefox won't start at all.
Hello, I just installed windows 10 on my nephews computer. I installed firefox so I don't have to use edge, but firefox won't start. It just flashes. I have tried re-installing firefox, deleted all mozilla and firefox files and folders and clean installed firefox, even reinstalled windows. Troubleshoot mode don't work, it just flashes too. I checked for Crash Reports, but there are none. The only time it works is when windows is in safe mode, I even upgraded to computer to windows 11 hoping that it would fix what ever is going on.
Installation
Hello, I have downloaded the Firefox browser in the past and used it for maybe 30 minutes or so. I cannot recall, but it would crash and then when I would try and open it, it just flashes for a second and instantly crashes so I am unable to use it. This seems to happen with both the installer and the Microsoft app.
sudden, various, problems
A few days ago, whenever I download an attachment from my email(Yahoo), the tab crashes after I do so. Assuming this is a Frefox issue....but not positive...has happened repeatedly since. Very annoying. Also, upon restart of Firefox yesterday, all my cookies were reset automatically. Had to re-log in everywhere. This never has happened before, without out me manually doing this. Any idea what is going on? Bill
Firefox keeps crashing
I'm using Firefox and I just installed it to get away from Chrome's Manifest V3. Whenever I try to open Firefox, even in safe mode, it flashes open then closes. The crash reporter doesn't even open. I need help!
Bugs on iPhone XR using iOS 15
I use this for more than 5 years on iOS, but the last 2-3 versions became horrible. On iPhone XR with iOS 15, the app stops working if I swipe down the control center and go back to the app. When I start the app, the most visited sites and their icons are flashing for 1-2 secs, and some sites are really slow (it is hard to scroll, it almost freezes). I hope you can fix these bugs. If you need screencast to see the phenomenon, I can provide it as well. Thank you!
