NoFace is a Firefox add-on, blocks HTTP connections to Facebook servers, intercept connections going to Facebook servers (currently facebook.com and fbcdn.net and all subdomains) and to block them (by returning Host Not Found). The purpose of this is to prevent Facebooks servers from being pinged at all as you surf the Web, thereby allowing them to track your browsing (via Referrer headers).
It is intended to complement tracker-blockers like Ghostery, which are outstanding but dont block all of Facebooks tools. If you have this add-on installed, Facebook will totally disappear from your browsing experience, except for seeing some The server could not be found messages in iframes.
