    Navigator.mozSetMessageHandler()

    This method is used to allow applications to register a function handler that can receive — and react to — a message from the system.

    Any application is allowed to register a handler to receive any message, but some messages will only be delivered to applications that have the corresponding permission. For example, an sms-received message will only be delivered to an application that has the sms permission.

    Contrary to DOM events, system messages will stay in the queue even if the application has no handler for them. You can check if your application has queued messages by calling navigator.mozHasPendingMessage() with the appropriate type as a parameter. When a message handler is set, all queued messages will be asynchronously delivered to the application.

    Syntax

    navigator.mozSetMessageHandler(type, handler);
