Hi, rolling back Firefox can now cause data loss so is not recommended. See Install an older version of Firefox.

You can first try restarting Firefox - 3-bar menu > Exit.

If that doesn't help, and in case a Refresh has occurred, please look on your Desktop for a file named Old Firefox Data - Refresh Firefox - reset add-ons and settings.

If the file isn't there, you can try this: Open bookmarks > Show All Bookmarks > Import and Backup > Restore, and see if you have a backup there.

If not, please see -
