Privacy Badger

Privacy Pros: Advanced tracker blocker that works without breaking functionality.

Privacy Cons: Browsers with multiple unique addons make a browser more fingerprintable.

Privacy Badger is a browser extension 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.
