mozbrowservisibilitychange

Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

The mozbrowservisibilitychange event is fired when the visibility state of the current browser iframe <iframe> changes, for example due to a call to setVisible().
