We're trying to put all the privacy essentials we can make seamless -- tracker blocking, upgraded encryption, private search and more to come -- all in one package, across all major browsers and platforms. In this respect, on any major mobile device or desktop browser, you should be able to look up DuckDuckGo and with one download get seamless privacy protection as you search and browse the web.

With regards to other extensions, we found that they generally lack some combination of all the essentials (e.g. missing encryption, private search), aren't totally seamless (i.e. break some of the web), or aren't available across all major browsers and platforms.

With regards to tracker blocking in particular, we would like to be as comprehensive as possible while not breaking the Web, and are close to that with this initial launch, utilizing some open source lists including Disconnect and Easylist. We are not currently using the machine learning aspects of Privacy Badger, however.

There are more nuanced UX differences, however. In the UI we're trying to move away from 'x trackers blocked' and instead group trackers from networks together, trying to identify the umbrella company and purposes.

Second, we're grading each site based on its privacy measures (including privacy policies with help from TOSDR), and telling you at a glance how protected you are on an A-F scale, based on what we could do (e.g. block trackers and upgrade encryption).

Thank you for the feedback on the right-click menu. We will look into that.
