Internet Doesn't work except Firefox?

Question

Nothing on my computer can connect to the internet except Firefox. I have tried itunes, internet explorer, opera, adobe acrobat, and divx player. Firefox is the only thing that works. I'm using wireless internet from my router, but on my other computers that use the internet everything works. I think it my have to do with Firefox, but i don't want to delete it because if i do i might not be able to get back on the internet.
