segmentation fault with firefox, seamonkey

[AIJAZ BAIG]

Hi..

I have been able to finally get the X11 up and running thnks to the
xorg.conf file supplied by gheorgie on freeBSD 7,0. So I installed xfce4
using sysinstall. I am now trying to install firefox. After installing
firefox using sysinstall, whenever i use it, it never starts and a seg-fault
occurs (with core dump).

This is also true with seamonkey as the very same thing happens. Is it
because xfce4 couldn't ascertain my domain name as when it starts it gives
me a warning that it couldn't ascertain my domain name (i supplied the
hostname myself during install)?

Where should I check the log of whats actually happening with them (as the
dumped core file is not human readable)?

Additionally, my cursor seems really fluttery when I use emacs (also
installed from the ports collection). Should I lower the refresh rates in
xorg.conf file?

Best Regards,
