This works by allowing an extension to set a value of Services.perms.DENY_ACTION
for permissions.default.desktop-notification, which stores the default permission
for desktop notifications. This means that if no permissions have been explicitly
set for a given page, the default will be used, but if a user overrides the permissions
for a specific page then their chosen permission will override this default.
An extension can only use this to make the default behaviour to disable notifications.
It cannot be used to globally enable notifications.

values: "normal", "none", "once". Behind the scenes it sets the image.animation_mode

This will modify the "dom.popup_allowed_events" preference to control whether events from
user actions are allowed to open pop-up windows or not. If set to `false` then pop-ups from
user actions will not be allowed and will result in a doorhanger being displayed informing
the user that a pop-up was blocked. If set to `true` then all of the default events
will be allowed to open pop-up windows.
