Problem solved with this support article:

After the automatic update to Firefox version 84, all my bookmarks, customizations, and add-ons are missing.

I saw something on the upgrade notice page when Firefox first ran (after the upgrade) about syncing to the previous version of Firefox to restore my bookmarks and other custom items, but I cannot find those instructions on the Firefox support site.

How do I get back all the things now missing?

Thank you.

Back up and restore information in Firefox profiles {web link} I use a Legacy add-on that makes backups of my user profile, Just In Case. Unfortunately, it is not compatible with the current Firefox.

Every now and then, open the profile folder and create a copy of the current profile as is to another location on your hard drive. This way you will have a backup.

If you do this each day, you will not lose much data. This should be done with Firefox Closed.

Note: In case you need to restore from these backups, you may need to overwrite old or corrupted files.
