As it seems this issue is already discussed as a firefox-bug here:
https://launchpad.net/distros/ubuntu/+source/firefox/+bug/14911
They say it's because the composite extension is enabled on edgy by default. I couldn't find it in my xorg.conf, but maybe it's a default used by the binary. So I tried this in my xorg.conf:
Section "Extensions" Option "Composite" "false" EndSection
As far as I can say there are no more crashes for me.
