Proxy-ad-dumper oleh DoDevAgain

This add-on is based on Mozilla's Proxy-Blocker example, but it has been modified in order to proxy adverts to an unknown location (127.0.0.1:65535), thus blocking stealthily unwanted ads. This add-on is not recommended for any end users who do not understand how does it work, as it is not exactly stable or done 'accordingly to the books'.
