Mozilla Firefox to begin blocking push notification requests

As an experiment, the web browser will offer the feature to select users of Firefox Nightly

Push notifications can be a powerful feature, allowing web sites to communicate with the user even once the site has been left. However, as the use of the feature has grown more popular, push notification requests have flooded the webspace. In response, Mozilla Firefox will be blocking requests for website push notifications on certain user's browsers beginning next year.
According to the popular web browser, their telemetry data suggest that users have increasingly seen a number of unsolicited permission prompts. These prompts may be out-of-context and sometimes discourage use of the site.
Last year, Firefox introduced a setting that gave its users the option to block push notification requests. It was a popular idea, but those who didn't check notification settings missed out. As a result, Firefox will begin experimenting with new ways to reduce the number of unnecessary push notification requests given. 
The experiments in blocking push notifications will take place on Mozilla's Firefox Nightly, a browser that offers pre-release versions to the user. Blocking push notifications automatically will take place in April, 2020.
Rather than receiving a push notification, users will get an animation in the address bar. This way if they opt to receive the notification, they can see the animation and click on it.

The browser will also run another experiment that will gather information on the user's interaction with permission prompts. This will give Firefox developers more knowledge on how people interact with these requests so they know how to handle them better in the future.
