title: fb.login popup doesn't display additional requested permissions if popups are blocked
body: <p>I am trying to request additional permissions at the time of a facebook login using Facebook's suggested Javascript SDK. I am using the scope parameter to make the additional request as a part of the FB.login(). My chrome browser has blocked popups. When I load the page containing the FB.login and the scope parameters into my browser, Chrome blocks the automatic popup. When I then click on an html button to perform the facebook login and authorization request, the only permissions that the fb popup shows is the one for basic info. However, if I allow popups, then when I load the page, a facebook authorization popup automatically displays without the need to click on the button to launch the fb login. When this automatic popup displays, it now shows the additional permissions I included in the scope parameters. How can I get the additional permissions to display in the fb login popup when popups are blocked?</p>
  
  <p>Below is my code:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  
  &lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;
    // Additional JS functions here
    window.fbAsyncInit = function() {
      FB.init({
        appId      : 'MY_APP_ID', // App ID
        channelUrl : 'channel.html', // Channel File
        status     : true, // check login status
        cookie     : true, // enable cookies to allow the server to access the session
        xfbml      : true  // parse XFBML
      });
  
      // Additional init code here
      FB.getLoginStatus(function(response) {
                  if (response.status === 'connected') {
                          // connected
                  } else if (response.status === 'not_authorized') {
                          // not_authorized
                                  login();
                  } else {
                          // not_logged_in
                                  login();
                  }
          });
  
    };
  function login() {
          FB.login(
                  function(response) {
                                  if (response.authResponse) {
                                  // connected
                                  } else {
                                  // cancelled
                                  }
                  },
                  {scope: 'email, user_birthday'}
          );
  }
  
    // Load the SDK Asynchronously
    (function(d){
       var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
       if (d.getElementById(id)) {return;}
       js = d.createElement('script'); js.id = id; js.async = true;
       js.src = "//connect.facebook.net/en_US/all.js";
       ref.parentNode.insertBefore(js, ref);
     }(document));
  &lt;/script&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  &lt;button type="button" onclick="FB.login()"&gt;login&lt;/button&gt;
  &lt;/body&gt;
  &lt;/html&gt;
