For the last 1 year, Firefox has been reliably crashing on my machine (M1, macOS Monterey, Version 12.0.1) after a undefined period of use from the time I start up my computer. Sometimes is an hour, sometimes 30 minutes, sometimes it can last the whole day. Once it happens, it will first lose internet connection, none of the sites would load, then the only thing I can try to do is to quit it. But Force quitting or pkill -f Firefox on terminal does not entirely quit it even though the window is closed, some process is still running that prevents it from really quitting. In about 50% of the time, this crash will then spread to my entire computer, and I have to press and hold the power button to restart. This cycle will repeat a few times a day. Its completely debilitating. I have tried uninstalling (including removing all library files), reinstalling newest version, upgrading my OS etc. Problem will go away for a few days and then will slowly creep back. Happy to provide any info that you need for diagnosis.

Thank you! L
