Privacy Badger

Meet Privacy Badger

Privacy Badger is a browser extension that limits third-party tracking. It uses learned information about tracking behavior to decide which domains to block or restrict, receiving periodic updates from its training system. The extension also sends privacy preference signals and removes some tracking from outgoing links.

Its menu shows the third-party domains involved in a page and provides controls for adjusting how they are handled. Potentially useful embedded widgets can be replaced with click-to-activate placeholders, letting you choose when to load them. The focus is tracking protection, so advertisements are blocked when they act as trackers rather than through a rule to remove every ad.
