+
+// nsGlobalWindow inherits PRCList for maintaining a list of all inner
+// windows still in memory for any given outer window. This list is
+// needed to ensure that mOuterWindow doesn't end up dangling. The
+// nature of PRCList means that the window itself is always in the
+// list, and an outer window's list will also contain all inner window
+// objects that are still in memory (and in reality all inner window
+// object's lists also contain its outer and all other inner windows
+// belonging to the same outer window, but that's an unimportant
+// side effect of inheriting PRCList).
+
+// NB: Currently nsPIDOMWindowInner and nsPIDOMWindowOuter are identical classes
+// with identical member variables and identical vtables, that only differ in
+// type name. nsGlobalWindow doesn't want to doubly inherit (and have two
+// copies of everything), and it also doesn't want to privilege one over
+// the other by making it possible to convert types through the C++ type system
+// instead of our accessor methods (AsInner and AsOuter) that do dynamic
+// checking. So we inherit from nsPIDOMWindow<nsISupports>, which is also
+// identical to both nsPIDOMWindowInner and nsPIDOMWindowOuter, but not
+// convertible to either.

+   *        new window.
+   *
+   * @param aName the name to use for the new window
+   *
+   * @param aOptions the window options to use for the new window
+   *
+   * @param aDialog true when called from variants of OpenDialog.  If this is
+   *        true, this method will skip popup blocking checks.  The aDialog
+   *        argument is passed on to the window watcher.
+   *
+   * @param aCalledNoScript true when called via the [noscript] open()
+   *        and openDialog() methods.  When this is true, we do NOT want to use
+   *        the JS stack for things like caller determination.
+   *
+   * @param aDoJSFixups true when this is the content-accessible JS version of
+   *        window opening.  When true, popups do not cause us to throw, we save
+   *        the caller's principal in the new window for later consumption, and
+   *        we make sure that there is a document in the newly-opened window.
+   *        Note that this last will only be done if the newly-opened window is
+   *        non-chrome.
+   *
+   * @param aNavigate true if we should navigate to the provided URL, false
+   *        otherwise.  When aNavigate is false, we also skip our can-load
+   *        security check, on the assumption that whoever *actually* loads this
+   *        page will do their own security check.
+   *
+   * @param argv The arguments to pass to the new window.  The first
+   *        three args, if present, will be aUrl, aName, and aOptions.  So this
+   *        param only matters if there are more than 3 arguments.
+   *
+   * @param aExtraArgument Another way to pass arguments in.  This is mutually
+   *        exclusive with the argv approach.
+   *
+   * @param aLoadInfo to be passed on along to the windowwatcher.
+   *
+   * @param aForceNoOpener if true, will act as if "noopener" were passed in
+   *                       aOptions, but without affecting any other window
+   *                       features.
+   *
+   * @param aReturn [out] The window that was opened, if any.  Will be null if
+   *                      aForceNoOpener is true of if aOptions contains
+   *                      "noopener".
