Downloaded firefox yesterday and everything was fine, i could view everything as with IE but now there is a problem i tried viewing www.migweb.co.uk but i keep getting this error msg:

Server not found


Firefox can't find the server at www.migweb.co.uk.


* Check the address for typing errors such as
ww.example.com instead of
www.example.com

* 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.

So then i tried viewing it with IE and i cannot view it that way either. Can anyone help me on what i have done?
