I've been trying to connect to msn while I've been working on my computer at uni but I don't seem to be able to work out how to set up the settings.

To connect to the web at uni I have to go to the connection settings in firefox. and put in the proxy server in the Automatic proxy configuration URL: setting and then when I try to load a web page I have to enter my name and password.  I've tried doing different things in msn but I can't seem to work it out.  Can anyone help me out?

Cheers
