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.

(gdb) thread apply all backtrace

Thank you for the email.  

Since then, fortunately or unfortunately, the crash has not occurred.  FYI, I attach an output of "(gdb) thread apply all backtrace" when firefox got frozen (this was not recognized by ABRT or SELinux).

Thank you for the bug report. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find.
