I encountered this when doing a partial upgrade to edgy for things like firefox2 and some other choice apps I wanted to check out. I fixed it by upgrading libnss3 to the version in edgy then purging firefox and reinstalling it. I got the idea to do that from a suggestion for FC at LQ.org: http://www.linuxquestions.org/questions/showthread.php?t=492018
