It is not recommended to do that, as it may cause security bugs.
XPCNativeWrapper is the security measure preventing you from accessing
JS inside content webpage (see
http://developer.mozilla.org/en/docs/XPCNativeWrapper ).

If you control the webpage, it's better to communicate to it via DOM events.

If you absolutely have to access unsafe JS objects, you can do that
using wrappedJSObject property. It's probably a good idea to avoid
interacting with the page directly from chrome though, run the code in
a sandbox (http://developer.mozilla.org/en/docs/Components.utils.evalInSandbox
) instead. Something like:

var s = Components.utils.Sandbox(content);
s.win = content;
Components.utils.evalInSandbox("win.function()", s);
