Question : Where is the exact location where Firefox stores bookmarks (favorites) on Windows XP?

We setup a new server in this office which necessitated users rejoining a domain which caused NEW profiles being created for them on their Windows XP clients.  The new profile does not have their Firefox 3.6 bookmarks which we stupidly did not back up from before.  I'm sure they are somewhere on the computer under a different profile, so I need to put them in to where Firefox for the current user's profile will see them.  Anybody have any good ideas where they may be?

ADWS was not running on the domain controler.  This was preventing Exchange from creating the AD user account.
