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 mozbrowserusernameandpasswordrequired event is fired when the content within a browser <iframe> requires an HTTP authentification.
The embedder is supposed to retrieve the necessary credentials, usually using a dialog or a database of username/passwords, and then call authenticate() or cancel() as appropriate.
