Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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