Firefox Problem

[Happydude]

ok...this has never happened to me until today:

i wanted to download new drivers for my motherboard audio...when i clicked on a link that was supposed to get me to the mirrors page for me to download, instead brought me to a page like this (see Problem.jpg). also when i wanted to try download.com, it gave a similar page, just with more "writing". i know this is a problem with firefox, because i tried the same link and download.com on IE and it works perfectly.

what i want to know is: has anyone encountered this problem before and if you havem how did you go about fixing it?
