There are some B2G specific code paths[1] related to apps that will need some additional work before this could be true on all platforms. I am not sure how this would be affected by the new B2G approaches mentioned in this thread. I filed <a rel="nofollow" href="https://bugzilla.mozilla.org/show_bug.cgi?id=1254823">https://bugzilla.mozilla.org/show_bug.cgi?id=1254823</a> about this. > * Add support for <iframe mozbrowser usercontextid=X> similar to > <xul:browser usercontextid=X> which already exist. This also seems reasonable and should be straightforward to add.
