[1] Previously, the type of sandbox was a DOMString instead of a DOMSettableTokenList. This has been fixed with Gecko 29.0 (Firefox 29 / Thunderbird 29 / SeaMonkey 2.26)) (バグ 845067). Other browsers may still implement the property as DOMString since it was a late change in the specification.

Firefox OS notes

Firefox OS extend the HTMLIFrameElement interface to support browser iframes. Those extra methods are made for privileged applications which want to implement a browser like application for Firefox OS devices. Not that in that context, the HTMLIFrameElement also inherit methods from the EventTarget interface. To learn how to implement such applications, see the Using the Browser API article.

Allows the parent to explicitly change the visibility state of the browser iframes.
Returns the current visibility state of the browser iframe. Returns a DOMRequest.
HTMLIFrameElement.sendMouseEvent(type, x, y, button, clickCount, modifiers)
Send a mouse event to the browser iframe.
HTMLIFrameElement.sendTouchEvent(type, identifiers, touchesX, touchesY,radiisX, radiisY, rotationAngles, forces,count, modifiers)
Send a touch event to the browser iframe.
Navigate the browser iframe back.
Navigate the browser iframe forward.
Reload the browser iframe.
Stop loading the browser iframe content.
Allows to remove the all browsing history of the browser iframe.
HTMLIFrameElement.getScreenshot(maxWidth, maxHeight)
Allows to take a screenshot of the browser iframe's content, scaled to fit within maxWidth and maxHeight pixels. Returns a DOMRequest.
Add a listener to recieve an event the first time the browser iframe is ready to paint (This listener is sent an event after the first MozAfterPaint event is dispacted in the iframe.)
Remove the listener added by the previous function.
Returns a DOMRequest which result is a boolean indicating wether the browser iframe can be navigate backward.
Returns a DOMRequest which result is a boolean indicating wether the browser iframe can be navigate forward.
