I know how HTML5 notifications work. And I know how to use them in production. But what I can't understand is, the behaviour of Facebook: Even if you close all tabs of facebook, when you receive message, desktop notification appears. Doesn't matter if you use Mac or PC.

How is it possible to execute javascript when there is no open tab (session)?

How does facebook send html5 notifications even if tab closed?
