"Server not found" Problem loading Firefox?

Question

I downloaded Mozilla Firefox 2.01 today because I've heard it's better than IE at tracking cookies and preventing viruses. But when I try to open it, pages won't load and it says "Server not found." I checked Windows Firewall to make sure that Firefox was permitted to access the Net, and it is. What's the problem? IE still works fine, everything opens and functions normally.
