Facebook Authentication - Unsafe JavaScript attempt to access frame with URL

Question

I am trying to implement Facebook Login System into my website.

While it try to connect to facebook, I get an error from console log:

Unsafe JavaScript attempt to access frame with URL https://s-static.ak.fbcdn.net/connect/xd_proxy.php?xxxxxxxxxxxxxxxx

I am using JavaScript SDK

I added this in the body tag:

<div id="fb-root"></div>
<script>
    window.fbAsyncInit = function() {
        FB.init({
            appId      : 'xxxxxxxxxxxxxx',
            status     : true, 
            cookie     : true,
            xfbml      : true
        });
    };
    (function(d){
        var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
        js = d.createElement('script'); js.id = id; js.async = true;
        js.src = "//connect.facebook.net/en_US/all.js";
        d.getElementsByTagName('head')[0].appendChild(js);
    }(document));
    </script>

Facebook Login button:

<div class="fb-login-button"  data-perms="email">Login with Facebook</div>

I am testing from localhost - I have register my website on facebook develop apps (Site URL: http://localhost)

How to fix this problem? or should I use PHP SDK?

Edit: Same problem when I uploaded to server with public domain.

Answer 1

The error that you see there is a non-fatal error. There is no workaround for this, as your browser is advising you that it is not a great idea to load JavaScript from foreign domains. Just ignore this message and look elsewhere for bugs if your scripts do not run. Sajith is also correct that you can't debug from localhost.
