Missing bookmarks
As if this morning, all my bookmarks have disappeared. I did a Firefox search for the problem and got a page titled "My bookmarks have disappeared". I followed the directions:
1. Click on the menu button to open the menu panel. Click Bookmarks and then click the Manage Bookmarks bar at the bottom. 2. In the Library window, click the Import and Backup button and then select Restore. 3. Select the backup you want to restore from the list of dated automatic backups.
You can also select Choose File...to restore bookmarks from the manual backup, if you created one.
4. After confirming your choice, the bookmarks from the backup you selected will be restored.
The backup was not restored. I need help.

The places.sqlite and favicons.sqlite files contains your History and Bookmarks. And it looks like they are corrupted.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.
Locate the above files. Then rename or delete them. Restart Firefox. The browser should then create a new place.sqlite and recover your bookmarks from the backup files.
Note: Your history is not backed up and will be lost.
