Unfortunately there is no backup for history, but try searching in File Explorer for 'Places.sqlite' which is where Firefox stores your browsing history.
That will show a list of any bookmark backups that Firefox has made simply click one to restore it. Open the Firefox menu and select Library>Bookmarks>Show all Bookmarks.įrom the toolbar in the window select Import and Backup and hover on Restore. First thing to try is to look if Firefox has made backups of your bookmarks that are still there.
