BigSur and Firefox

Firefox seems to reset to a newly downloaded state without reason. All my bookmarks and custom settings are lost. This has happened several times now and I do not know if it is a BigSur issue or a Firefox issue. My Mac was just updated to BigSur and I did not have this problem on Catalina. I am about to give up on Firefox because of this issue.

Macs: Make sure you install Firefox properly and that you do not run Firefox from within the DMG (Disk Images) file.
