title: Facebook login button doesn't work on Firefox
body: <p>I'm using Facebook's javascript SDK CDN and a button to log my users who prefers to login with their Facebook account.</p>
  
  <p>However my Facebook login button works on every browser besides Firefox.</p>
  
  <p>This is the button I'm implementing;</p>
  
  <pre><code>&lt;button class="fb-login-button" data-scope="public_profile,email" onlogin="checkLoginState();" name="facebook" value="facebook"&gt;FACEBOOK&lt;/button&gt;
  </code></pre>
  
  <p>What's wrong with the code that deals with Firefox? It only refreshes the page on click.</p>
