HTMLIFrameElement.getManifest()

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.

Return value

A promise that resolves to a JSON object representation of the loaded app's manifest.

browser.addEventListener('mozbrowserloadend',function() {
  var request = browser.getManifest().then(function(json) {
    console.log(json);
  });
});
