1. Before Chrome 22, the support for notification followed an old prefixed version of the specification and used the navigator.webkitNotifications object to instantiate a new notification. Before Chrome 32, Notification.permission was not supported. Before Chrome 42, service worker additions were not supported. Starting in Chrome 49, notifications do not work in incognito mode.
