Firefox automatically creates backups of your bookmarks, which can be helpful if your bookmarks are lost or missing. To recover them, follow the instructions below.

1. Use one of these methods to open the Bookmarks Library window:
   • Click the Firefox button to open the menu and click on Bookmarks.
   • Click the Bookmarks menu and click on Show All Bookmarks.
2. At the top of the Library window, click the "Import and Backup" menu and select Restore.
3. Click the date of the bookmark backup you want to recover.
4. In the new window that appears, click OK.
5. 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.

Did this fix your problems? Please report back soon.

Everything has been restored and I now know how to fix it if this happens again.

Thanks again.

You're welcome.
Thank you for using the Mozilla Support Forum.

If you have accidentally removed bookmarks then use "Organize > Undo" in the bookmarks manager (Bookmarks > Show All Bookmarks) to get them back.
The Organize button is the first of the three buttons next to the Back and Forward buttons on the toolbar in the Library (Bookmarks Manager).
That only works if you haven't closed Firefox.
Otherwise you will have to restore the bookmarks from a JSON backup.
