Redirección de Facebook después de iniciar sesión

I have read a number of questions and answers, including esta on StackOverflow and none works. My question to all responses I have seen are 'does it work in Safari?'.

I am trying to get this to work with Safari. It works on Chrome and Firefox fine. But in Safari the login screen just freezes and I get the "Unsafe JavaScript attempt to access frame with URL" log message.

I have a canvas app. I want to log the user in and redirect them to a page once they have logged in. I am trying to redirect directly after login. I have tried

1. pólipo window.top.location to a facebook url (with some data passed to a signed request as the all_data argument)

2. pólipo window.location to a URL with the same domain as my app.

3. suscribiéndose al auth.login event and putting the redirect there

4. putting the redirect in the callback to login

None of these works for Safari. I'm starting to think that there's no way to do it.

function doSomething()
{
  FB.login(
    function(loginResponse)
    {
      if (loginResponse.authResponse)
      {
        window.top.location = "my url"
      }
    },
    {
      scope:"some,scope"
    }
  );
}
}

In response to Nitzan Tomer, here is the equivalent code which doesn't work with Safari but does work with others:

function myThing()
{
  FB.login(function(loginResponse)
    {
      if (loginResponse.authResponse)
      {
        FB.api('/me', function(response)
        { 
          window.location = "http://my_app.com?x=" + response.xyz;
        });
        }
    },
    {
      scope:"scopes"
    }
  );
}
