Hello,

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.

Thank you.

I'm not missing my bookmarks. I'm missing all my downloads and history from Feb. to July 10. They show up again on July 11. I have Recuva but don't have a clue as to where to tell it to look or what to ask it to look for.

All I know is they were there when I signed off one evening and the next morning when I signed on, they were gone. All of the downloads are gone but they are stored in my downloads folder so that won't be a problem, but I'd still like to know how they went "poof". My history is missing from February (when I started using FireFox) through July 10. On July 11, they show up again. I would appreciate any assistance you can provide.

These can't get your data back, but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backup of files that you choose.
