It's only true in Firefox if people write code like:
var foo = "bar";
however not good if they write:
if (foo) {
doStuff();
}
But I think the Window is the best place to put it as long as we use a
name that is descriptive enough that it's unlikely to collide with
existing pages. I'm not a fan of names like 'performance' which was
recently added by another spec.
