Firefox Focus: The privacy browser

Lots of Internet browsers have an incognito function, but that doesn’t mean that websites don’t track your and or that ads are not served. What the new Internet browser from Mozilla is doing is to offer a new kind of experience for users that doesn't involve aggressive ads or online tracking.
 
Furthermore, when a user closes the browser, the history, passwords, and cookies are deleted as well, which means that you won’t be followed around by targeted ads. The application promised to block pretty much all of the major tracking features available right now and to improve the overall experience and performance by blocking ads that consume important resources.
