title: How to run insecure content using chrome extension
body: <p>I'm using chrome extension to add  in https://* pages, but when I want to load pages from http://*, chrome blocked the page saying: </p>
  
  <blockquote>
    <p>[blocked] The page at https://* ran insecure content from http://*.</p>
  </blockquote>
  
  <p>So I wonder, is there any method or API to avoid such situation?</p>
