I emailed with him a few times offlist... He's in Gentoo in the GNOME
Environment.  I thought of permission issues, so suggested that he run
firefox as root, but looks like he tried it and it didn't work.

It definitely sounds like a system or network issue, though.

Maybe something funky in the .mozilla folder underneath the
/home/username directory.

I'm not sure if all the Mozilla browsers like Seamonkey, Epiphany, and
Firefox use that directory or not.
