Firefox
Firefox 86.0 (64bit) Ubuntu 20.04.2 LTS Gnome 3.36.8 Desktop: Intel 2 core E7500 CPU AMD RV710 Graphics Memory 3.8GiB Firefox entire display including menu bars covered with colored confetti which moves in response to mouse movement. Firefox Safe Mode is not affected. No other application on this system is affected. Effects all user log ins on this system. Action: Complete uninstall (purge) of Firefox and cache then reinstall--No Fix i.e no additional AddOns. I believe this uninstall/reinstall removed Firefox and downloaded a fresh copy.

That's pretty extreme.
Could you try disabling Firefox from using hardware acceleration? This is a potential workaround for incompatibilities between Firefox and your graphics card/chipset driver software. This article describes where to make that change: Firefox's performance settings. This will take effect the next time you exit Firefox and start it up again. Any difference?
Since hardware acceleration improves the appearance of fonts and animations, you may want to check whether graphics card/chipset driver updates are available for your system. This article suggests safe ways to do that: Upgrade your graphics drivers to use hardware acceleration and WebGL.

Just as a test, can you download to a folder and run it to see what happens? I got off my distro Firefox a few months ago and have been running from a folder.

Thanks to all on forum. I seem to have a fix. As per jscher2000
Unchecked -Use recommended performance settings Unchecked -Use hardware acceleration when available.
This problem may have come with the last upgrade of Firefox. Some software seems to be dropping support for older systems. I have an i7 system on standby for when my existing system (daily use) fails but it just keeps going.
