Firefox 404 page

Even since I installed Comodo, I’ve gotten this page when I mistype an address in Firefox:

http://i36.tinypic.com/o5nwis.jpg

It’s extremely annyoing, I want my old google search page back. How do I do that?

It’s because you’re using Comodo’s DNS, if you don’t like it change your DNS to Google’s on OpenDNS.
