title: How to debug on Facebook Internal Browser (Mobile)?
body: <p>I'm developing website with a lot of HTML5 and CSS3 features. I'm also using iframe to embed several content on my website. It works fine if I open it using Chrome/Firefox/Safari mobile browser. However, if I share on facebook (post/page) and I opened it up with Facebook application with Facebook Internal Browser, my website is messed up. </p>
  
  <p>Is there any tools or way to debug on Facebook Browser? Thanks.</p>
