[Greasemonkey] Access netscape.xxx objects?

[Bill Donnelly]

also, btw, I don't think

var transfer = Components.classes['@mozilla.org/widget/transferable;1'].
    createInstance(Components.interfaces.nsITransferable);

will work outside of an extension.

I've tried to get stuff like that (Components.classes) to work in
"regular JS", and I don't think any of it does.
