The Electronic Frontier Foundation has announced the 1.0 release of the Privacy Badger browser extension. “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).
