Hello,

Sorry to hear about that. First, Firefox automatically creates backups of your bookmarks, which can be helpful if your bookmarks are lost or missing.

• Click the Bookmarks button (or Menu > Bookmarks) and select Show All Bookmarks.
• At the top of the Library window, click on Import and Backup and select Restore.
• Click the date of the bookmark backup you want to recover.
• In the new window that appears, click OK.
• Your bookmarks from the selected date should now be restored.

For more information, see the Restore bookmarks from backup or move them to another computer article. For other solutions, see the Recover lost or missing Bookmarks article.

thank you!

Thank you. When I do that, I get an error message: "Unable to process the backup file." I tried selecting different dates.  !@#$#^%!

You can check for problems with the places.sqlite database file in the Firefox profile folder.

Personally! I added the Places Maintenance: https://addons.mozilla.org/firefox/addon/places-maintenance/ add-on, ran a deep scan from the "options button within the Places Maintenance add-on" and it said my database was corrupt and would be replaced on the next Firefox start. When I restarted Firefox, all of my bookmarks were restored.

Hope it will work for you. Thanks !
