DuckDuckGo Privacy Essentials por DuckDuckGo

Privacy, simplified.

Tired of being tracked online? We can help. At DuckDuckGo, we believe online privacy should be simple.

DuckDuckGo Privacy Essentials comes packed with best-in-class privacy essentials and makes browsing in Firefox even faster.

• Block Tracking Cookies — prevent most 3rd-party cookies from tracking you as you browse from site to site. 
• Escape Online Tracking — block most hidden tracking scripts lurking on the websites you visit (e.g., when you click on search results). Stop companies behind those trackers before they use sneaky tactics to try to collect and sell your data. See notes and links below for more information.
• Search Privately — our private search engine comes built-in so you can search the Internet without being tracked.
• Enforce Encryption — force many 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.
• Signal Your Privacy Preference with GPC — built into the browser, Global Privacy Control (GPC) intends to help you express your legal opt-out rights automatically. This will tell websites not to sell or share your personal information under future legal frameworks (e.g., CCPA, GDPR) in various states or countries.

Privacy, simplified.

Note about our tracker blocking for 3rd-party sites and emails: 
DuckDuckGo never tracks you. When you leave our search engine to use other sites, we aim to block as many hidden trackers as possible, but we can't block them all for a few reasons. New trackers emerge all the time, so first we need to find them. Then, blocking these trackers can sometimes break functionality, so we need to develop new approaches without hurting usability. Additionally, in our extension we offer a specific type of protection that stops scripts from even loading on 3rd-party sites, which isn’t offered on most popular browsers by default. Currently, this one loading protection doesn't apply to Microsoft scripts on 3rd-party sites due to contractual restrictions. However, our other tracker blocking methods are unrestricted.
