Explicitly set the size of FB.Login()?

Currently I'm using the following function to instantiate a login dialog using Facebook Javascript SDK

 function fbLogin() {
            FB.login(function (response) {
                if (response.status === 'connected') {
                    // Logged into your app and Facebook.
                    window.top.location = "http://ift.tt/1BAb2BC";
                } else if (response.status === 'not_authorized') {
                    // The person is logged into Facebook, but not your app.
                    alert("2");
                } else {
                    // The person is not logged into Facebook, so we're not sure if
                    // they are logged into this app or not.
                    alert("3");
                }
            },{scope: 'email'});
        }

Is there any way to control the size of the popup that appears ? say for example, 500 x 500 px ?

Thanks
