firefox halts system when visiting specific website

[Perseid]

Every time I visit brightcreative.com my system halts for about a minute (I can only move the mouse). Xorg seems to use 100% CPU time of one of my cores at this time (top isn't very responsive as well). Last time I switched with [ctrl][alt][F1] my x server crashed and restarted.

This is the output firefox produced from startup to shutdown:
/usr/share/themes/Blubuntu/gtk-2.0/gtkrc:169: Clearlooks configuration option "progressbarstyle" is not supported and will be ignored.
