I can determine what ads I do and do not want to block. How many other ads does Focus by Firefox not block?<p>Edit: Y&#x27;all downvote weird shit sometimes. Marco quit the ad blocking game because he didn&#x27;t want to be the arbiter of what did and did not get blocked. It&#x27;s perfectly reasonable to question what a given blocker will and will not block. And perfectly valid to wish to have that control.
