Why does Mozilla close unexpectedly?

Good day, SuSE 8.2 Pro. Mozilla 1.2.1 included in distro. When I visit a certain web site (www.comon.dk) mozilla often close (crash?) all by itself. It usually happens some time during page download, but on oocasion it doesn't happen until a few seconds after page download has completed. A few times it has not happened. I can find nothing helpful in /var/log/ Starting Mozilla from the command line gives no information. A new prompt is displayed, as if I closed mozilla myself. Has anyone experienced anything like this? Are there any logs or trace functionality I can enable or check? Best regards :o) Johnny :o)
