Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please install firefox-debuginfo; in order to do this you have to enable
yum install --enablerepo=\*debuginfo firefox-debuginfo
(if you use x86_64 firefox, install firefox-debuginfo.x86_64 package).
Then run firefox with a parameter -g. That will start firefox running inside of
gdb debugger. Then use command run and do whatever you did to make firefox
crash. When it happens, you should go back to the gdb and run
(gdb) thread apply all backtrace
This produces usually many screens of the text. Copy all of them into a text
editor and attach the file to the bug as an uncompressed attachment.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
Also, 18.104.22.168 should be making it's way out to mirrors very soon.

requested debug output (but see comments - may be incomplete)
(1) check (& install) debuginfo pkg:
$ yum --enablerepo=\*debuginfo list available '*irefo*'
firefox.i386 22.214.171.124-1.fc7 updates
firefox-32.x86_64 0.0.1-5.fc7 fedora
firefox-devel.x86_64 126.96.36.199-1.fc7 updates
firefox-devel.i386 188.8.131.52-1.fc7 updates
$ rpm -qa|grep firefox
(2) run firefox w/ -g option
$ which firefox
$ file /usr/bin/firefox
/usr/bin/firefox: Bourne shell script text executable
$ firefox -g
$ uname -m
[so, i think the script sets:
so, maybe i need to run firefox-bin directly:
hmm, doesn't seem to recognize -g option?
(note: --help does not list any -g 'Mozilla option' either.)
not clear whether inconsistency in pkg versions might be an issue.
so, run under gdb (not sure if backtrace info is due to
debuginfo, since i did not check it prior to installing
in any case, backtrace stdout is attached.
(if more info is needed, i'll be offline for the next week or so).
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.
Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008.
Fedora 7 is no longer maintained, which means that it will not
receive any further security or bug fix updates. As a result we
are closing this bug.
If you can reproduce this bug against a currently maintained version
of Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
