IMPORTANT POINTS TO REMEMBER:

Configuring a Web Browser to Use a Proxy:

Firefox:

Select Tools->Options (or Edit->Preferences) from the menu. Click on the 'Advanced' icon in the Options dialog. Select the 'Network' tab, and click on 'Settings' in the 'Connections' area. Select 'Manual Proxy Configuration' from the options available. In the boxes, enter the hostname and port where proxy program is running.

Configuring Firefox to use HTTP/1.0

Because Firefox defaults to using HTTP/1.1 and your proxy speaks HTTP/1.0, there are a couple of minor changes that need to be made to Firefox's configuration. Fortunately, Firefox is smart enough to know when it is connecting through a proxy, and has a few special configuration keys that can be used to tweak the browser's behavior.

Type 'about:config' in the title bar. In the search/filter bar, type 'network.http.proxy' You should see three keys: network.http.proxy.keepalive, network.http.proxy.pipelining, and network.http.proxy.version. Set keepalive to false. Set version to 1.0. Make sure that pipelining is set to false.
