That does provide a bunch more information. Thank you.

Here is the output when Firefox crashed when trying to load a web
page. I can definitely get another one for when Firefox crashes when you
exit, and I can probably get another one for when it crashes when you
reload a page, but that's a little less easy to reproduce.
(to maintain some readability, I removed the "loading" lines)

$ gdb /usr/local/lib/firefox3/firefox-bin 1303
