Be in control of which cross-site requests are allowed. Improve the privacy of your browsing by not letting other sites know your browsing habits. Secure yourself from Cross-Site Request Forgery (CSRF) and other attacks.

DuckDuckGo (HTML SSL) de DuckDuckGo

DuckDuckGo is the search engine that doesn't track you. We also have smarter answers and less clutter. This extension adds DuckDuckGo (non-JS HTML version) to the search bar. For more features, see the DuckDuckGo Plus add-on. Enjoy!

Collector's Note Java free version. Very handy with NoScript.
