... Array and Array.prototype in each window are different ... bla-bla-bla ...
I know this.
But any object will be different, not only Array, but only for array we have Array.isArray.
So anybody who loves to use objects from another "window", should avoid usage "instanceof".

I agree @Yaffle Array.isArray is an ES5 method so not supported by older browsers, but it reliably determines if an object is an Array.
