[[Recovering important data from an old profile]] can help

HOW? do I recover bookmarks on different hard drive? When book marks were not saved?

You can backup the bookmarks on the old computer and create a JSON or HTML backup and restore or import this file in the Bookmarks Manager (Bookmarks > Show All Bookmarks). You can use an USB stick to transfer the saved bookmarks file to the new computer.<br /> You can also copy the places.sqlite file from that computer to have the bookmarks and the history. *http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox *http://kb.mozillazine.org/Backing_up_and_restoring_bookmarks_-_Firefox
