DuckDuckGo Privacy Essentials
Free open-source browser extension that blocks third-party trackers in Chrome, Edge, Firefox and Opera.
In short
- The extension is available for 4 Windows browsers: Chrome, Edge, Firefox and Opera2.
- The extension is free, according to DuckDuckGo's Firefox Add-ons listing9.
- The source code is on GitHub under the Apache 2.0 licence3.
- DuckDuckGo says it does not save or share your search or browsing history7.
- Cookie pop-up handling is not supported in the extensions yet4.
This extension suits people who want free tracker blocking that works straight from a browser store, with open source code and a no-history policy2,3,7. It costs nothing and the Chrome version uses Manifest V38,9. The catch: the vendor documents no custom block rules, cookie pop-up handling is unsupported, and its ad-blocking and scam-blocking pages describe only its own browser2,4,5,6.
Best for: People who want free tracker blocking without an account.
