Based on reverse tracking tests, FirefoxFocus provides little if any true tracking protection, prevention of meta data gathering, or anonymous surfing. Although the settings imply a significant level of privacy protection, the actual performance on a basic level is wanting. This in turn creates doubt in other claims, specifically data collection for “development” suggesting Tor and VPNs are much more private. There is no current ability to equip FirefoxFocus with add-ons to enhance privacy, making FirefoxFocus very limited considering its claims at the time of installation. This may be a function of Siri integration and Apples data gathering policies, that remains to be seen. Apple has proven to be an intrusive host, I consider iOS a Faustian bargain, comparable to Facebook, Google, Twitter, etc... Nothing is free, the costs are much greater than we perceive. If you are someone who throws caution to the wind, then “run free Little Bob”.
