Privacy Badger is a new browser extension being developed by EFF (Electronic Frontier Foundation) to protect your online privacy. Privacy Badger blocks spying ads and invisible trackers. It’s there to ensure that companies can’t track your browsing without your consent.
While there are tools like Disconnect which also do the job well Privacy Badger gives you a clearer view of which trackers are trying to track you. It also allows you more control on dealing with the trackers.
Privacy Badger sends a Do Not Track header with each request and when it finds that the request is not being honored, it automatically blocks any requests being sent to the domain. Each tracker is denoted by 3 suggestive states: GREEN (unblocked), YELLOW (do not send cookies or referrers) and RED (block). You can change the state manually too. 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.
It is still in an Alpha stage as we write and needs more testing. We encourage readers to try it out and send feedback or bug reports. Currently it supports Firefox and Google Chrome.
Similar extension for Firefox – Ghostery.
