How do I import Firefox bookmarks from a hard drive into another PC's Firefox browser? The hard drive containing the bookmarks was removed from a computer whose motherboard died but the hard drive can be recognized externally on the new computer.

Edmeister, thanks for your reply but the user I was assisting hadn't backed up his bookmarks, so there was no individual bookmark backup file to restore and/or import to the new machine...we ended up copying the entire Mozilla folder from his old hard drive to his new hard drive and his bookmarks showed up then. I had him immediately export his restored bookmarks to a backup file and told him to repeat this process every time he added a new bookmark so he always had the most recent set.
