Hi, before you roll back you could try to see if the data can be recovered, Somewhere on your computer there should be a folder called Old Firefox where the files should be inside.

Recovering important data from an old profile Back up and restore information in Firefox profiles

And if that does not work you can get the earlier updates from here: Install an older version of Firefox

If there is no Old Firefox folder on the desktop:

Type about:profiles<enter> in the address bar. How many profiles are listed? How many should be there? Also, open the profile folder in your file explorer.

Thank you, I was able to find my backup files with your help. Have a great day
