Hi, I think it would be better to write export XLIB_SKIP_ARGB_VISUALS=1 into /etc/firefox/firefoxrc which is sourced by /usr/bin/firefox and should survive the next update.
I had a similar Problem with libflash: https://bugs.launchpad.net/ubuntu/+source/libflash/+bug/80949 -- Firefox crashes when following links from www.failuremag.com. https://launchpad.net/bugs/27927 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
