About this Add-on
In the manual mode (default) you need to choose a protocol (http, https, socks4, or socks5) and enter a desired IP and Port, then press ON/OFF button to start the proxy. For the automatic mode, the extension uses its online server to search for a working proxy based on the protocol(s) and origin you have chosen.
Moreover, animated icons show you when a proxy is in use. Advanced logging shows you which proxies were used. If you have any question or concern, feel free to contact me via the following address above.
