Description :
Mozilla Firefox, formerly known as Phoenix and Firebird, is a redesign
of the Mozilla browser component, similar to Galeon, K-Meleon and
Camino, but written using the XUL user interface language and designed
to be cross-platform. It is a stand-alone application instead of part
of the Mozilla Application Suite.

Does the "Quality Feedback Agent" window open when you crash?
If so, please submit the crash data and let us know the incident ID.

mats: sadly linux vendors do not ship out binaries.

reporter: bug 422916 comment 14 should explain how to get debuginfo

Comment 3

[Guy Zelck]

I installed the firefox-debugging package and ran /usr/lib/firefox/run-mozilla.sh -g -d gdb /usr/lib/firefox/firefox-bin.
My point 2. should read as "Click Enter". I did that and got to see the next page for the 1st time but was stuck after that. I guess SIG33 is what previously made the browser crash. The browser-window remained visible this time, probably because we're in debug mode.
I'm on uncharted territory here, you guys should take it from here.

it sounds like you're using a super useless kernel, google suggests downgrading to a more conventional kernel :(.

This bug is either fixed or unreproducable. It's been more than 1,5 years ago too since it occured. No need to let this gestate any longer.

(Fwiw, the "Enter" button is a Flash object.)

Guy, thanks for your report and your efforts getting us additional information.
Please file a new bug should it occur again in a recent version of Firefox.
