This is excellent news:

Today we’re taking a major step to simplify online privacy with the launch of fully revamped versions of our browser extension and mobile app, now with built-in tracker network blocking, smarter encryption, and, of course, private search – all designed to operate seamlessly together while you search and browse the web. Our updated app and extension are now available across all major platforms – Firefox, Safari, Chrome, iOS, and Android – so that you can easily get all the privacy essentials you need on any device with just one download.
I have a multitude of blockers installed, which makes it difficult to recommend just one to people. Hopefully this will simplify things:
For the last decade, DuckDuckGo has been giving you the ability to search privately, but that privacy was only limited to our search box. Now, when you also use the DuckDuckGo browser extension or mobile app, we will provide you with seamless privacy protection on the websites you visit. Our goal is to expand this privacy protection over time by adding even more privacy features into this single package. While not all privacy protection can be as seamless, the essentials available today and those that we will be adding will go a long way to protecting your privacy online, without compromising your Internet experience.
It looks like the code is all open source, too! 👏 👏 👏
