I had this problem also with Flash site after upgrading to Gusty. Following a suggestion found at http://ubuntuforums.org/showthread.php?p=1672572 I changed my color depth in /etc/X11/xorg.conf from 16 to 24. Now Firefox no longer crashes on Flash sites for me.
I had reduced the color depth to 16 to use Compiz I think. I had the color depth at 16 before with Fiesty while trying out Beryl or Compiz but I had no trouble with Firefox as I recall.
I have a IBM T40 notebook with VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)
