The initiative to create a mobile browser that would prevent tracking of user activity and provide the ability to bypass censorship on the Internet was launched a year ago. Together with the Tor Project, the Guardian Project took on the task of creating such a browser, and the basis for the development was the Orfox application, whose developers are involved in Google Summer of Code (GSoC) - an initiative program by Google, within the framework of which an annual selection of student projects with open source code is held.

Explaining their choice, the Tor Project developers say that Orfox is a great candidate for porting Tor Browser settings and features. The first thing they did was port the Security Slider feature from the desktop to Orfox. It allows users to choose which features on websites should be blocked for security purposes. For example, you can disable the JavaScript engine or automatic video downloading and playback — sometimes used by hackers to identify visitors.
