Firefox 3.5 in Fedora not loading unless from terminal as root

When logged in as a normal user in Fedora 12, Firefox will start (indicated by the Starting Firefox on the bottom panel), but disappears and does nothing.  Firefox will open if run from the terminal as root.

I have changed the owner of all firefox files (with the exception of the one found in /usr/share/applications) to my user, but it still refuses to run.

How can this be fixed?

Thanks in advance.

Revert all firefox files to their original permissions.
Try running firefox from terminal as user. Post any error messages which will appear.

No errors. The terminal just jumps to the prompt, as if I used Firefox and then just closed it.
Maciej SsysadminCommented:
Try running (still as user):
strace -eopen -ofirefox-output.txt firefox
You will then have firefox-output.txt file. Post its content (or attach it) here.

This is what the strace program resulted in.

I do thank you for the response, but I have come up with another solution.

I found this article:

I am not sure why Firefox 3.5 was crashing, and the strace program did yield an answer (whatever it may be since I am not sure what I am looking for when I see the output).

My solution is to simply install the later version instead of the 3.5 version that is found in Fedora's "Add and Remove Software" repository.
