To setup your proxy in Firefox you need to follow these steps

• Right click on the shortcut in start menu and select Mozilla Firefox Options.
• Click on the Advanced category.
• Click on Network tab.
• Click Settings under Connection.
• Check Manual proxy configuration.
• Enter proxy server IP address and port number. Your proxies were delivered as PROXY_IP:PORT_NUMBER like for example 1.2.3.4:0000 so in this example 1.2.3.4 would be the IP and 0000 would be the port number
• check the box that says Use this proxy server for all protocols.
• Click OK twice and browse to www.whatismyipaddress.com or www.iplocation.net to check that it shows the IP of your proxy as being your own
