When I visit sites, for example kongregate, the boxes or spaces where ads would be are still there, just no ad, not sure if that is intentional. Also a similar thing happens on youtube, with big empty spaces being left just no ad, and on the homepage of youtube, I have to click this close ad button, to get rid of the big space there.
Cosmetic adblocker is not yet implemented to remove the blocked frames. You can track the issue here
