Only Safari can connect to internet

[waffles123]

I've been using Safari for awhile and it's been working fine. However, the Macheist chat stopped loading the past few days, and I know it's just me, because other people can connect. So I thought I would download Firefox to see if that would work, but when I type in a webpage in Firefox, it would just give me a blank white page. So I thought it was just a bad preference file, so I deleted it, but Firefox did the same thing. So I downloaded Firefox 2, and the same thing happened. Now I was a little freaked out, as you can imagine. Then I downloaded Camino, and the same the happened-a blank white screen! Only Safari can connect to the web. Please help

How are you connecting to the internet? Is it on a work or home network?

It's a home network.

I'm having the same problem but not just with Firefox. When I try to connect to the itunes store or get updates I get a message saying that I have no internet connection.
