Today we’re pleased to announce the launch of Focus by Firefox, a free content blocker for Safari users on iOS 9 that gives users greater control of their mobile Web experience. Focus by Firefox puts users in control of their privacy by allowing them to block categories of trackers such as those used for ads, analytics and social media. Focus by Firefox may also increase performance and reduce mobile data usage by blocking Web fonts. We welcome your feedback as we explore ways to offer more features in Focus by Firefox in the future.

Users can download and install Focus by Firefox from the App Store, and once it is installed, launching the app will provide a guide to finish configuration. Focus by Firefox will block the same trackers that are blocked by Private Browsing with Tracking Protection in Firefox for Windows, Mac, Linux and Android, based on Disconnect’s open source blocklist.

Currently, Focus by Firefox only works with Safari, not Firefox for iOS. This was not our choice—Apple has chosen to make content blocking unavailable to third party browsers on iOS. We are exploring how we can provide this feature on Firefox for iOS and will deliver it as soon as it’s possible.
