This seems to be a sticky problem, it has been going on quite long,
through various firefox and mozilla versions.

>Description:

firefox and mozilla both tend to hang after being around for some
time.  The problem seems random and does not happen on specific pages
and is not triggered every time on a specific page.  Seems a bit like
a thread problem.  The process does not die, it just locks up, no X
activity, kill window terminates the process.  The browser is always
dead within an hour if I leave it on a page updating itself regularly.

I have heard that this was bugging some NetBSD people as well some
time ago.

I tried gdb but it does not seem to like threaded software:
