Reporter, If this is a reproducible bug, we need some more information from you, if you are willing.

First, could you elaborate on the steps required to reproduce it?

Then, see next comment.

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.

First of all, could we get output of the command, saved in a text file and
attached to this bug:

$ rpm -qa *xulrun* *firefox* *mozilla* *flash* *plugin*

Please also install firefox-debuginfo.

# debuginfo-install firefox

Then run firefox inside the gdb debugger. Please do the following:

$ firefox -g

Stuff will appear. Ignore this until you get the gdb command prompt, then do:

(gdb) run

Now, firefox should start up. Use it and reproduce the crash. When firefox
crashes, you should be back to the gdb prompt. Now do:

(gdb) thread apply all backtrace

More screens of stuff will occur. Copy all of this part to your editor of
choice, such as gedit, and save it as an uncompressed file and attach it to
this bug report.

We will review this issue again once you've had a chance to attach this
information.

Thanks in advance, for your extra efforts.

Firefox gdb thread apply all backtrace dump file

The gdb dump file on a Firexfox crash case.
Operations performed:
$ firefox -g
(gdb) run
Firefox crash with a Show Passwords selection on Preferences forms
(gdb) thread apply all backtrace

Good back-trace from abrt and gdb back-trace attached. Cause of crash listed as "Firefox crash with a Show Passwords selection on Preferences forms". Reporter, if you can be more explicit with your exact series of steps we could use to reproduce this issue it would be helpful, but since the cause is listed, I am setting keyword triaged and status and assigning.

backtrace is good but at least since frame #22 has nothing to do with Firefox and all to do with libcanberra:

libcanberra? Looks more like a dlopen() issue? glibc problem or more likely some memory corruption from mozilla.

*** Bug 583012 has been marked as a duplicate of this bug. ***

*** Bug 583171 has been marked as a duplicate of this bug. ***

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  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bug reports from releases that are no longer maintained.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 '12'.

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 12'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 12 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 to the applicable version.  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.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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.
