title: Unable to test facebook like button on localhost (unlike before)
body: <p>I had developed one small webpage with facebook social plugins (like, recommend and send buttons). I could test the buttons and the click events successfully on localhost till around a month ago; but suddenly the buttons are not working on localhost now. They work only if I deploy the webpage on a public IP through "localtunnel". On localhost, they show the number of likes and names, but don't give a flyout on clicking the button. Also, the subscribed event "edge.create" is not fired.</p>
  
  <p>I have copied all the required javascript from the facebook like button widget page.
  I also found out that there is some difference in the traffic pattern on localhost and tunneled deployment. The GET oauth request returns 302 status on localhost while 200 on public domain. Also, the deployment on public domain makes many GET requests after clicking the button to fetch some CSS and images. Whereas the localhost page makes only one request and stops there.
  I am not able to understand why this is happening.</p>
  
  <p>Has facebook recently stopped supporting anything required for testing the buttons on localhost?</p>
