*Summary*: window.orientation returns a value corresponding to the screen orientation. The orientationchange event is fired when the orientation of the viewport is changed. These features are non-standard but have been implemented by other browser vendors on mobile platforms leading to widespread usage on major websites. In order to improve web compatibility, these features are also going to be implemented by Gecko on mobile platforms and we are also working on standardizing the feature. Web authors should avoid these features because the values returned by window.orientation are unreliable as it means different things across different platforms. Instead, authors should use the ScreenOrientation API which offers the more functionality and better specified behavior.
