I wonder if something got scrambled in her FF applications area.

Can she try IE 8 and see if if works for her that way?

or she can do a reinstall of FF -
my dh windows account/profile side of the computer was doing some weird things with his FF. so I just re downloaded it and reinstalled it , it kept all his bookmarks and settings. and fixed the problem.

To be sure she doesn't lose any bookmarks or settings by accident she can back them up in a separate file place. info below -
