content/base/public/nsimessagemanager.idlscriptable provides methods for managing message listeners on local frames.

Communicating with frame scripts
objects an object whose properties are any cpows exposed by the sender as the third argument to sendasyncmessage() in the example below the listener just logs all the messages details: // chrome script messagemanager.addmessagelistener("my-addon@me.org:my-e10s-extension-message", listener); function listener(message) { console.log(message.name); console.log(message.sync); console.log(message.data); console.log(message.target); console.log(message.objects); } so combining this message listener with the message above will give console output somewhat like this, when the user clicks a <div>: "my-ad...
... synchronous messaging to send a synchronous message, the frame script uses the global sendsyncmessage() function: // frame script sendsyncmessage("my-addon@me.org:my-e10s-extension-message"); when a chrome script receives a synchronous message, it should return a value from its message listener: // chrome script messagemanager.addmessagelistener("my-addon@me.org:my-e10s-extension-message", listener); function listener(message) { return "value from chrome"; } this value is then presented to the frame script in the return value of sendsyncmessage().
... removemessagelistener() to stop listening for messages from content, use the message manager's removemessagelistener() method: // chrome script messagemanager.removemessagelistener("my-addon@me.org:my-e10s-extension-message", listener); chrome to content to send a message from chrome to content, you need to know what kind of message manager you're using.

Frame script loading and lifetime
the script just writes "foo" to the command line: // chrome script var mm = gbrowser.selectedbrowser.messagemanager; mm.loadframescript('data:,dump("foo\\n")', true); loadframescript() takes two mandatory parameters: a url that points to the frame script you want to load a boolean flag, allowdelayedload note: if the message manager is a global frame message manager or a window message manager, loadframescript() may load the script multiple times, once in each applicable frame.
...for example: var mm = window.messagemanager; mm.loadframescript("chrome://my-e10s-extension/content/frame-script.js", true); the script will be loaded into all tabs currently open in this window, and all new tabs opened afterwards.
... if you use allowdelayedload, you can cancel it by using removedelayedframescript: var mm = window.messagemanager; mm.removedelayedframescript("chrome://my-e10s-extension/content/frame-script.js"); this means we will stop loading the script into new tabs.

the frame script's global is a contentframemessagemanager, giving it the following environment: content the dom window of the content loaded in the browser.
... if you use a capturing event listener on the contentframemessagemanager, you should verify that its event.target is set to the contentframemessagemanager global object in order to avoid handling unload events from content.
