I've just installed Ubuntu 20.04.03 LTS. Firefox has since booting up caused freezes at different times. I have logged in remotely and ran kill -9
to kill all instances of Firefox and the system recovers. But now that I learned patience if I wait up to and beyond 5 minutes the system will run normally and Firefox will work as expected. I have run top
when remotely logged in but nothing shows as a problem and Firefox isn't even shown. I should say that most freezes happen as Firefox is loading.
There are no addons or plugins other than any that may have come installed from the start. Yet the problem persists through multiple reboots.
