As discussed on dev-webapi[1] the app that wants to use widgets only need the "embed-widgets" permission to use <iframe mozbrowser mozwidget> If the app also wants to implement a browser, it could request the "browser" separately. A <iframe mozbrowser mozwidget> will have restricted mozbrowser API defined on the prototype if the embedder has the "brower" permission; they will always throw when used. [1]: https://groups.google.com/d/msg/mozilla.dev.webapi/uQweGWtVKRA/Bj1jZq3LN-0J --HG-- rename : dom/apps/tests/test_widget.html => dom/apps/tests/test_widget_browser.html
