The index.dat file is used by IE and not by Firefox. Firefox uses a SQLite database file named places.sqlite to store the history and the bookmarks. You would need to restore an older copy of this places.sqlite file to recover the deleted history.
</p><p>You can try to restore a previous version of the places.sqlite file if there is one with a promising date/time stamp.<br>
Make sure to first backup the bookmarks because those will be restored as well.
