The problem is with this image: www.howtoforge.com/themes/htf_glass/images/bg_header_bottom_left15.png It is 10.000 pixels wide (very ugly hack). It is a "bug" in the page (I'll try to report it to howtoforge), but gecko shouldn't have any problem displaing it (less than a megapixel).
And I think it _is_ a security risk, as it could lend to a DoS as reported above. -- Rubén Rodríguez GNU no es UNIX! http://es.gnu.org
