Components run in their own JS scope; there is no | window | object.
And since XUL windows actually store global variables as properties of
the | window | object, you can't conflict :)

In fact, each .js file gets its own scope; that makes JS components
nice in the sense that you no longer have to worry about conflicting
with other extensions (which is a rather annoying problem when your JS
runs in the window).
