nsISupports
Last changed in Gecko 7.0 (Firefox 7.0 / Thunderbird 7.0 / SeaMonkey 2.4)Starting with Firefox 44, this file is empty as its features were either no longer used or are only available from C++ code; see dom/base/nsPIDOMWindow.h for those.
While this interface is not officially defined by any standard bodies, it originates from the de-facto DOM Level 0 standard.
Starting in Firefox 3, DOM windows are actually based on nsIDOMWindow2, which is a subclass of nsIDOMWindow that adds some new features to this interface.
Gecko 7.0 note
In Gecko 7.0 nsIDOMWindow2 has been merged into this interface.
Gecko 8.0 note
In Gecko 8.0 nsIDOMStorageWindow and nsIDOMWindowInternal have been merged into this interface.
