Privacy Badger

From RaySoft

As you browse the Web, Privacy Badger looks at any third party domains that are loaded on a given site and determines whether or not they appear to be tracking you (e.g. by setting cookies that could be used for tracking, or fingerprinting your browser). If the same third party domain appears to be tracking you on three or more different websites, Privacy Badger will conclude that the third party domain is a tracker and block future connections to it.[1]

For certain websites, if Privacy Badger were to block an embedded domain entirely it would break the site's core functionality. For example, if Privacy Badger were to block 'licensebuttons.net', 'Creative Commons' buttons would no longer load. In these cases Privacy Badger blocks the domain from setting or receiving any cookies or 'referer' headers, but allows the embedded content to load.[1]
