If you use Sync then best is to disconnect Sync temporarily during troubleshooting.
This could be a problem with the places.sqlite and favicons.sqlite files in the Firefox profile folder.
- use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support) page
If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.
If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder with Firefox closed. Firefox will rebuild places.sqlite and restore the bookmarks from the most recent JSON backup in the bookmarkbackups folder.
- keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
- you lose the history when a new places.sqlite is created
You may have to restore an older bookmarks backup in the bookmarkbackups folder via the Bookmarks Manager (Library).
- Bookmarks -> Manage Bookmarks -> Import & Backup -> Restore
- https://support.mozilla.org/en-US/kb/restore-bookmarks-from-backup-or-move-them
The name of an automatically created JSON bookmarks backup in the bookmarkbackups folder includes a total item count (folders and separators included) and an hash value to prevent saving the same backup more than once. You also see this count in the Restore menu drop-down list.
- bookmarks-YYYY-MM-DD_<item count>_<hash>.jsonlz4.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
