Electronic Frontier Foundation

Electronic Frontier Foundation is launching a new extension for Firefox and Chrome called Privacy Badger. Privacy Badger automatically detects and blocks spying ads around the Web, and the invisible trackers that feed information to them.

Privacy Badger is EFF's answer to intrusive and objectionable practices in the online advertising industry, and many advertisers' outright refusal to meaningfully honor Do Not Track requests.

Privacy Badger is a browser-add on tool that analyzes sites to detect and disallow content that tracks you in an objectionable, non-consensual manner. When you visit websites, your copy of Privacy Badger keeps note of the "third-party" domains that embed images, scripts and advertising in the pages you visit. If a third-party server appears to be tracking you without permission, by using uniquely identifying cookies to collect a record of the pages you visit across multiple sites, Privacy Badger will automatically disallow content from that third-party tracker.

Advertisers and other third-party domains can unblock themselves in Privacy Badger by making a strong commitment to respect Do Not Track requests. By including this mechanism, Privacy Badger not only protects users who install it, but actually provides incentives for better privacy practices across the entire Web.
