Oh, never mind. I got it now:
function Foo() {
this.wrappedJSObject = this;
...
}
Foo.prototype._findWindow = function() {
var wm = Components.classes["@mozilla.org/appshell/window-mediator;1"]
.getService(Components.interfaces.nsIWindowMediator);
var e = wm.getEnumerator("navigator:browser");
while (e.hasMoreElements()) {
var w = e.getNext();
var tabBrowsers = w.document.getElementById("content");
var browsers = tabBrowsers.browsers;
for (var i = 0; i < browsers.length; i++) {
var browser = browsers[i];
var window = browser.docShell.DOMWindow;
var foo = window.foo;
if (foo.wrappedJSObject == this) {
return window;
}
}
}
return null;
};
Thanks anyhow.

I have a follow-up question. So, I'm now able to let Web pages' script
access my own custom object, window.foo. Now I need window.foo to know
which "window" it is attached to (as there can be many windows and many
tabs). Getting the top-most window would not work, as a Web page's
script does not always access window.foo while the page's window is
top-most. I'm trying to dig into the Javascript runtime stuff and
somehow get the outer context of the call to createInstance() but
haven't found anything.
Any suggestion?
Many thanks!

Hi all,
I'm trying to write a Firefox extension that adds an extra property
to the "window" object that Web pages' scripts have access to. As you
know, currently, scripts in Web pages can access such objects as
window
window.document
window.navigator
window.netscape
...
I'd like to add my own property onto this window object that all Web
pages' scripts can access
window.foo
I will provide the implementation of foo as necessary. I'm hoping
that someone here can tell me how to do this. I've tried a number of
methods (such as overloading the <browser> XBL binding), but I don't
see how to do this cleanly from within an extension.
The major issue is probably security. And I can't require every Web
page that wants to use this object to be signed so that it can
request privileges.
Many thanks in advance!

(I'm ignoring the .jseng copy of this exact same message)
One options is to do what window.sidebar does it at
http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/browser/components/sidebar/src/nsSidebar.js&rev=1.11#228
I think. I'm hoping whatever window.sidebar does is secure - so you
probably need to look at its nsIClassInfo impl too :)
