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 mozbrowseractivitydone event is fired when something inside the browser <iframe> triggers a web activity, and that web activity's message is consumed by the receiving app.

If the activity has a returnValue set to true, then the activity is consumed when postResult or postError is invoked on the activity by the receiving app.

Note: For activities where the receiving app's activity definition in its manifest does not include returnValue or returnValue is false, no mozbrowseractivitydone event will be generated as of the landing of bug 1194525 in Firefox OS 2.5. postResult and postError calls made on such an activity will be ignored and have no effect.
