Copy the folder(s) if you have more than one folder

Make a folder on the desktop. Paste on Desktop in the folder for example using control v

Once that is done

Install firefox as normal

There's many different methods but this easier

Press Windows + R to open the run command

Type firefox (or firefox.exe) -p

You see choose user profile

There is a default folder. Leave this be

Add-Ons for Firefox crash since update to 80

I left Firefox open over night and attempted to login to LastPass this morning - all the addons crashed. I had Firefox Task Manager open at the time and before attempting the login all addons were in the list and not using very much resources. After attempting login, all of the addons disappeared from the Firefox Task Manager list.

I will try the additional suggestions.

If I want to try a new profile without losing my saved/sync profile (and hopefully with the option of syncing my data back into the new profile) what steps should I take? Or is it just a given that if it is profile corruption, the sync profile is junk...?

Thanks!
