Here is another trace generated after the installation of firefox-dbg package. I didn't find any particular information on how to use it, so I only reproduced the crash using the normal firefox launcher ... hope this will help you.
Again, let me say that I have beryl installed but I have reproduced the crash with and without the 3D desktop ... ** Attachment added: "firefox-dbg trace" http://librarian.launchpad.net/4971926/_usr_lib_firefox_firefox-bin.1000.crash -- opening a popup crashes firefox https://launchpad.net/bugs/70052 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
