For some unknown reason when I went into Firefox all my bookmarks were missing. So I followed these steps: 1. Clicked on Show your bookmarks 2. Clicked on Manage bookmarks 3. Clicked on All Bookmarks 4. Clicked on Import and Backup all Bookmarks 5. Clicked on Restore 6. Clicked on latest Backup and it showed all the latest backups 7. Clicked on the latest backup and it came back saying it could not be done. What is going on and how can I restore my bookmarks?
