NOTE: All packaged Firefox add-ons are affected by Firefox bug #1508827 . A workaround is provided in the bug report. Please do not give negative karma just because of that bug.

Privacy Badger is a browser add-on that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. 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.
