Firefox Focus (focused on privacy) will test an ad blocker integrated into the browser.
On the bug tracker of the application, some have mentioned the presence of this ad-blocker in Firefox Focus 9.0, a version still under development and scheduled for February 12. It is stated that this is A/B Testing and that only 50% of the users will have access to this feature at first in order to check how this affects the use of the application and the loading time pages.

FF Focus is for android / iOS
The Focus team has decided to not move forward with the A/B experiment so we no longer need this dashboard.
