Well,
I just downloaded Firefox and it says
Unable to connect Firefox can't establish a connection to the server at en-us.start.mozilla.com.
* The site could be temporarily unavailable or too busy. Try again in a few
moments.
* If you are unable to load any pages, check your computer's network
connection.
* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
And yes, I turned IE first.
You're not on the network. Even if you are physically connected.
