Ok, well if you can't reproduce and figure out steps for us to be able to reproduce (and with no duplicates of this bug report) then there is nothing that we can do to figure out what happened and how to fix it (if it was a problem with Firefox). Thank you for the report but I'm going to close this as INCOMPLETE. Please reopen if you can provide reliable steps to reproduce.
