nsIBrowserDOMWindow in Firefox 3.6a1pre

 The C++ source has access to the browser script source through
 nsIBrowserDOMWindow. It is intended to be attached to the chrome DOMWindow
 of a toplevel browser window (a XUL window). A DOMWindow that does not
 happen to be a browser chrome window will simply have no access to any such
 interface.

Constants

 Values for openURI's aWhere parameter.


 Do whatever the default is based on application state, user preferences,
 and the value of the aContext parameter to openURI.

const short OPEN_DEFAULTWINDOW = 0

 Open in the "current window".  If aOpener is provided, this should be the
 top window in aOpener's window hierarchy, but exact behavior is
 application-dependent.  If aOpener is not provided, it's up to the
 application to decide what constitutes a "current window".

const short OPEN_CURRENTWINDOW = 1

 Open in a new window.

const short OPEN_NEWWINDOW = 2

 Open in a new content tab in the toplevel browser window corresponding to
 this nsIBrowserDOMWindow.

const short OPEN_NEWTAB = 3

 Values for openURI's aContext parameter.  These affect the behavior of
 OPEN_DEFAULTWINDOW.


 external link (load request from another application, xremote, etc).

const short OPEN_EXTERNAL = 1

const short OPEN_NEW = 2

Methods

 @return whether the window is the main content window for any
         currently open tab in this toplevel browser window.

boolean isTabContentWindow(in nsIDOMWindow aWindow)

 Load a URI

 @param aURI the URI to open. null is allowed.  If null is passed in, no
             load will be done, though the window the load would have
             happened in will be returned.
 @param aWhere see possible values described above.
 @param aOpener window requesting the open (can be null).
 @param aContext the context in which the URI is being opened. This
                 is used only when aWhere == OPEN_DEFAULTWINDOW.
 @return the window into which the URI was opened.
