Reducing notification permission prompt spam in Firefox

In the interest of protecting our users and the web platform from this, we plan to experiment with restricting how and when websites can ask for notification permissions. This leads us to believe that

Last year Firefox introduced a new setting that allows users to entirely opt out of receiving new push notification permission prompts. We suspect that these numbers might not paint a full picture of the resulting user experience, and we would like to get a real world impression of how requiring user interaction for notification permission prompts affects sites in the wild.
