Firefox Push Notifications
PushKit lets you send real-time notifications directly to people who subscribe from their Firefox browsers. These Firefox push notifications will work on Windows, Mac OS X and Linux. Your subscribers will see notifications directly on their desktop.
What are Firefox Push Notifications?
Firefox Push Notifications is a form of real-time communication which allows you to engage with your audiences by sending them regular notifications on desktop and mobile. Starting with Firefox 44, you can now send push notifications to people on their Firefox browsers, even if they are not browsing your website at that point of time. Notifications will arrive even if the browser is closed.
