It seems that now Edgy's firefox 2.0rc2 (1.99+2.0rc2+dfsg-0ubuntu1) has this bug, too. Tried running firefox even with '--sync --safe-mode' command line options but it didn't help. Gdb didn't say anything usefull, too.
Running 'XLIB_SKIP_ARGB_VISUALS=1 firefox' is a good workaround to run without crashes. -- Flash plugin problem with ARGB visuals causes crash https://launchpad.net/bugs/14911 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
