In a webapp where you present user a button to activate notifiactions, when the user clicks the button seemingly nothing happens in FF72 (user is focussed on a big enable notifiactions button in the web app and may not notice that some tiny gray icon wiggled a little in the address bar).

On a big screen a button in the middle of the screen is so far away from the address bar, that you don't see any change in the address bar at all in the peripheral vision.

So yeah, web apps that don't try to force the user to enable notifications are now punished for good behavior again.

EDIT: So it's not so stupid, see below.
