Firefox won't start

[Fridtjof Busse]

Hi
I just installed FreeBSD 5.4RC, everything works so fine.
Just firefox won't work (running xfce), neither the package nor the
port. I can only start it as root, under a normal user nothing happens
at all. /usr/X11R6/bin/firefox quits after a second and no firefox.
How can I fix this?
Thanks.
