• How to clear the Firefox cache {web link}

I previously cleared cookies which didn't help. Running in safe mode didn't help either. However, after shutting down and starting normally the next day, commenting wasn't a problem (some add-ons were disabled). After viewing a couple short YT videos, my PC crashed and rebooted indicating a problem with "start up." Windows tried to fix it (the screen looked like a fake version of Windows so I turned off the modem), but it couldn't fix it and offered to restore before adding recent programs. This reverted Firefox 92 to 85. Not sure if I should reinstall 92 again. To be fair, the PC has some videocard/driver issue and occasionally stalls and crashes. I don't know if 92 is adding some strain to the system.

Keep using v85 if you think v92 is causing problems. I suggest running some diagnostic programs on your system.
