Review below bug
Bug 480548 – Firefox closed by itself just after it starts when many tabs are loading at the same time

Try to reproduce the bug in rawhide using tools described in comment #1:
<commment #1>
First of all, could we get output of the command

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

Please also install firefox-debuginfo (debuginfo-install is from
yum-utils package).

debuginfo-install firefox

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.

Here the messages I got from dmesg after my firefox closed unexpectedly

Bug 487663 –  Huawei mobile broadband fails with NetworkManager >= 0.7.0.97

Comment #3 From  Dan Williams  2009-02-27 18:13:57 EDT  ——-

What mobile broadband card do you have, and what provider?

Also, are you comfortable using the terminal?  There are a few things we can do
to figure out what’s going on, including getting a root shell and turning on
serial debugging.  That would involve:

(both as root)
1) service NetworkManager stop
2) NM_SERIAL_DEBUG=1 /usr/sbin/NetworkManager –no-daemon

Then start the connection from the applet.  When it fails, grab the output and
attach it to this bug.  Thanks!
