I'm not sure what the problem is ... does it happen with other GTK+ applications as well? Can you get a backtrace of the firefox crash ? To do this, install 'firefox-dbg' and run 'firefox -debug'. When firefox crashes, type 'bt' and then 'thread apply all bt' and attach the output to the bug report.
