mozbrowsericonchange 编辑

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 mozbrowsericonchange event is sent when a new icon (e.g. <link rel="icon"> or <link rel="apple-touch-icon">) is available in the browser <iframe>'s content.

It will be fired once for each icon available.
