Firefox Focus is a free and open-source privacy-focused mobile browser from Mozilla, available for Android and iOS smartphones and tablets. Firefox Focus was initially a tracker-blocking application for mobile iOS devices, released in December 2015. It was developed into a minimalistic web browser shortly afterwards. However, it can still work solely as a tracking-blocker in the background of the Safari browser on Apple devices.
Firefox Focus seems to be a trade-free browser for mobile phones, as it blocks trades like trackers and ads. Therefore 5/5 blocks.
