DuckDuckGo Privacy Essentials

DuckDuckGo Privacy Essentials is a browser add-on / extension that helps protect your privacy on-line. DuckDuckGo Privacy Essentials provides the following tools:

Escape Online Tracking — automatically block hidden third-party trackers we can find lurking on websites you visit, which stops the companies behind those trackers from collecting and selling your data.
    
Search Privately — the Duck Duck Go private search engine comes built-in so you can search the Internet without being tracked.
    
Enforce Encryption — force sites to use an encrypted (HTTPS) connection where available, protecting your data from prying eyes, like from unwanted snoopers and Internet service providers.
    
Decode Privacy — each site you visit gets a Privacy Grade (A-F) so you can see how protected you are at a glance, and you can even dig into the details to see who we caught trying to track you.
