Bug in font color dialog on forums.opensuse.org in Firefox

view story

http://forums.opensuse.org – When I write a post here and select text then click the font-color button, a blank grey dialog comes up. No colors are shown. Mousing over the dialog changes each grey square to a white one, but still no colors are shown. Anyone else having trouble with font colors here? (Picking that color was random. The color change works, but there is no way to see what the chosen color will be.) BTW, why no source view in this forum? (Distributions)
