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 mozbrowseropenwindow event is fired when a new window is required — usually when the content of a browser <iframe> successfully calls the window.open() method, or the user clicks on a link with an unknown target.

The embedder must use the <iframe> passed in the event.details.frameElement property as the new window content.
