How does it protect privacy ? Can it be used instead of No Referer ??....

Questa recensione riguarda una versione precedente (2.0.1-signed) del componente aggiuntivo. 

The add-on includes EasyPrivacy and a couple hundred of hand-crafted domains known by tracking users, such as quant server, g analytics, trends live, etc etc

I don't see a relation between that and NoReferer, assuming it just hides the Referrer HTTP header sent to servers.
