FF 3.5 extension: window.title is 'undefined'

From a sidebar in Firefox 3.5 I am getting a reference to the main window with:

var mainWindow = window.QueryInterface(Components.interfaces.nsIInterfaceRequestor)
               .getInterface(Components.interfaces.nsIWebNavigation)
               .QueryInterface(Components.interfaces.nsIDocShellTreeItem)
               .rootTreeItem
               .QueryInterface(Components.interfaces.nsIInterfaceRequestor)
               .getInterface(Components.interfaces.nsIDOMWindow);

Then, mainWindow.title is undefined (this works in Firefox 3.0).

I've also tried:

mainWindow.getBrowser().selectedBrowser.contentWindow.title (also undefined)

and it might be worth noting that

mainWindow.getBrowser().selectedBrowser.contentWindow.location.href

returns the correct URL.

Thanks! Noah

It was removed in bug 450977 after being deprecated since 2004.

If my reading of the bugs is correct, the correct replacement is document.title.

I think what you really want is mainWindow.content.document.title. The title attribute exists on a document, not a window and should work in 3.0 and beyond.
