'Mozilla said this week that it intends to run two experiments over the course of this month to determine the most adequate way of dealing with push notification spam, a growing problem that is slowly deteriorating the web experience for everyone. From a report:

The experiments will run in Firefox Nightly (v68) and Firefox Beta (v67). The Firefox Nightly experiment will run from April 1 to April 29. During this time, Mozilla said Firefox Nightly would only allow websites to show a push notification permission only after the user has clicked or pressed a key while on a website. All attempts to show a push notification permission request before a click or key press will be blocked by default. [...] In the last two weeks of the experiment, Firefox will show an icon in the URL bar, but with no visible popup on the page. Users can click this icon and accept any push notification permission requests if they wish so.'
