I have the same problem. I also think that it's related to the composite extension, which is default in edgy now (so not mention in xorg.conf).
The XLIB_SKIP_ARGB_VISUALS=1 firefox works well for me. I think simply add this line to the /usr/bin/firefox script should be enough. -- Consistent crash when visiting flash sites https://launchpad.net/bugs/35942 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
