This shouldn't be this difficult to troubleshoot.

Step 1:

touch /forefsck
shutdown -r now

This reboots Fedora. Upon reboot, all your partitions auto-fscked. This 
should fix any filesystem corruption that might result in application 
failures, like Firefox.

Step 2:

rpm -e firefox
yum install firefox

This removes and reinstalls Firefox, which would fix any unlikely 
application corruption.

If Firefox still fails to start up:

Step 3:

mv ~/.mozilla ~/.mozilla.save

This removes -- renames actually -- the Firefox configuration directory. The 
next time Firefox starts, it will create an empty, default, configuration. 
If Firefox now runs, you had a problem with a corrupted/bad configuration. 
You, of course, will lose all your bookmarks and extensions. If this fixes 
your problem, you can later try to recover to salvage and recover whatever 
your can, from your saved configuration directory.

If Firefox still fails to load, there are only two possibilities:

A. You're hitting a bone-fide bug in Firefox, for some reason.

B. Somehow, some unknown system libraries got corrupted.

You may be able to obtain some clues by running "firefox" from a terminal 
window, which would dump any errors that Firefox barfs to standard output or 
standard error, which you would not ordinary see when starting Firefox from 
the desktop.
