Configuring Mozilla Firefox 3.xx for use with the UCSD Web Proxy
Click on the Automatic proxy configuration radio dial button.
In the text field, type the proxy URL:
http://webproxy.ucsd.edu/proxy.pl
When you restart Firefox and attempt to load any UCSD Web page (http://www.ucsd.edu), your computer will prompt you for your UCSD network username and password.
Enter the first eight characters of your username (even if you believe it's longer).
Enter your password.
Click the OK button.
To test your proxy settings, click this Test Link. If Firefox is properly configured, it will bring up a 1957 article in Science by Roger Revelle.
