Privacy Badger is a free software web browser extension for Google Chrome and Mozilla Firefox, created by the Electronic Frontier Foundation. Its purpose is to block advertisements and tracking cookies that do not respect the Do Not Track setting in a user's web browser. The alpha was released on 1 May, 2014, followed by a beta on 21 July, 2014. While some of the code for Privacy Badger is based on Adblock Plus, Privacy Badger only blocks those ads which come with trackers embedded.
EFF says, "If an advertiser seems to be tracking you across multiple websites without your permission, Privacy Badger automatically blocks that advertiser from loading any more content in your browser. To the advertiser, it's like you suddenly disappeared."
Ian Paul, writing for PC World, mentions that Privacy Badger currently "only blocks third-party tracking, not first party", and mentions that prevention of browser fingerprinting is planned for a future release.
Nathan Willis, writing for LWN.net, describes the green, yellow and red sliders of the Privacy Badger menu as being a "nice visualization aid", making it easy for the user to toggle the trackers on and off, if desired - describing it as much easier to browse through than ad blocking addon interfaces.
Kif Leswing writing for GigaOM writes that "Privacy Badger’s blacklist is generated through heuristic blocking, which means it gets better the longer it is used", and writes that at present, Privacy Badger "breaks a lot of websites", but considers it important as it is created by a non-profit company, and sums it up as "more than good enough".
