The address bar can check the history and bookmarks to see if anything matches what you are typing. As to bookmarks;

=======================================

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.

Thank you for trying to help, I have tried to do that several times and still no avail. I have restarted firefox from the troubleshoot menu as well and still nothing!

it says unable to process backup

Hmm, look at the file with an edit program. See if the file looks okay. What is the file name / ext. Did Firefox show a list of backups?

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