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 mozbrowserfindchange event is fired when a search method is invoked in the browser <iframe> content.

This includes HTMLIFrameElement.findAll(), HTMLIFrameElement.findNext(), and HTMLIFrameElement.clearMatch().
