The General tab allows you to enable an HTTP Proxy
Server. If your network connection requires you to use an HTTP Proxy
Server to make HTTP connections, select the Enable HTTP
Proxy option and type your proxy server in the text field
with the format http://HOST:PORT. For example, to use the proxy server
http://squid.mysite.org on port 3128, you would enter
http://squid.mysite.org:3128 in the text field.
Additionally, if your proxy server requires a username and password,
select the Use Authentication option and enter
your username and password in the respective text fields.
