Firefox Community Forum

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected).  When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one.  They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience.  The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).

Dear Support Team,

I am currently experiencing a very frustrating issue with Firefox. I have been using it for many years, and it has always been my preferred and most comfortable browser for my daily work. I depend on it heavily, as all my bookmarks and other important information are stored there.

Over the past few weeks, Firefox has been crashing more than ten times a day. I have already tried all the troubleshooting steps suggested in forums and through AI-based support, but none of them have resolved the problem. I also attempted to install and use the Firefox Beta version, but the issue still continues.

In our environment, other users and devices are not encountering this problem, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please assist me in troubleshooting this issue? I have attached the error screen that appears after the crash along with the crash report for your reference.

No reports shows on about:crashes

Best regards

Firefox not responding. I have tried everything on the Help pages. I have tried reset of everything. I have uninstalled and reinstalled from scratch. Still: when I open it: Firefox does not respond. And everything else also is very slow then. In Windows joblist I can see Firefox with 7-15 threads. One of them "not responding". I have no problems with Chrome nor Edge - W11, 16GB Ram

Could someone please help me retrieve my crash report history? My Firefox crashes more than 10 times a day. When I check **about:crashes**, it doesn’t show any reports right now, although I saw some there a few days ago. Is there any way to recover those reports so I can submit them here for further guidance from experts?

Windows10 simply multiplies the numbers of active Mozilla Firefox Apps which are open. Every day for about two weeks I've been having to delete hundreds of Firefox Apps open in the Task Manager. So many open in a very short time it locks up the Win10 system. I've attached a pic

Win10 will no longer let me download & transmit a .jpg file, sorry

Watching a CNN video on YouTube Firefox suddenly freezes and does not accept any further actions. Even shutting down it will block the process and I need to use the "Shut down anyway" function. Similarly, Thunderbird will lock up in the middle of writing a response, but here it is just the window and I lose what I typed, but I can go back and push "reply" again and retype the answer. Whether these are down to similar issues I don't know. Obviously, this sounds like a graphics driver, so I made sure all updates are installed and there is no further update available for both, Firefox and Thunderbird as well as the system drivers.

Any pointer is appreciated as this is really annoying. Thanks
