Mozilla plans to integrate an adblocker into Firefox Focus 9.0, which is scheduled for release next month.
Firefox Focus is a browser application for Android and iOS mobile phones, and is designed with the goal of user privacy, without storing passwords, blocking ad and content crawlers.
In the current version of Firefox Focus, 8.1, the browser stops tracking scripts, which will block some ads that require or contain tracking scripts.
Mozilla in the upcoming version, 9.0, plans to add a full adblocker (ad blocking mechanism). The 9.0 version is scheduled to be released on February 12, 2019.
