title: Error with Chrome extension - "Mixed Content: This request has been blocked; the content must be served over HTTPS"
body: <p>I am using cross domain data calls in my chrome extension. I have created a PHP function to make use of an API. So I'm making a call to this function using JSONP and expecting to get the values in return. But this is the error I'm getting in the console.</p>
  
  <p>Can anyone help me with this. What is the problem here? What do I have to do? I do not have any experience with chrome extensions.</p>
  
  <p>In my situation I think that only YouTube is blocking the content because it is expecting the cross domain connections to be HTTPS. So it's not allowing the cross domain calls. Well that's what I think. But if that problem can be solved using a background script. Can you please help with how to proceed?</p>
