Privacy Badger for Chrome is a free extension/add-on designed to learn to block numerous invisible trackers automatically.
Instead of keeping records of what to block, Privacy Badger for Chrome learns by observing which domains appear to be tracking you as you browse the Web.
With your browsing, Privacy Badger sends the Do Not Track signal (https://www.eff.org/issues/do-not-track). If trackers ignore your wishes, Privacy Badger for Chrome will learn to block them. Once it encounters the same tracker on three different websites, it will initiate blocking.
Besides automatic tracker blocking, Privacy Badger for Chrome can also remove outgoing link click tracking on Facebook, Google, and Twitter.
Ghostery for Chrome, Firefox, Edge, Opera, Safari, and Android sees the "invisible" detecting trackers, web bugs, pixels, and beacons placed on web pages by over 1,900 ad networks.
Click&Clean for Chrome is a free solution for erasing your private information, browsing history, saved form information, passwords, download history, and cache from your PC.
