See bug 1934115 for more context.

Certain web APIs ping the parent process to open a permission prompt for users. While some APIs e.g. Notification.requestPermission() is guarded behind transient user activation, other APIs e.g. navigator.geolocation.watchPosition is not, and calling such API repeatedly can stress the parent process enough that the whole Firefox UI hangs.

Notification.requestPermission() is actually also an issue because the parent process is still pinged to trigger the animation.
