This can be a problem with the file localstore.rdf in the Profile Folder.

Delete localstore.rdf or rename the file to localstore.rdf.sav in the Profile Folder to test if the file is corrupted.

See http://kb.mozillazine.org/Corrupt_localstore.rdf
(caution: do not delete the localstore.rdf file in the Firefox program installation folder)
