title: How to enable mixed content (insecure mode) in browsers (Chrome, Opera, FF) for local development at Mac OS?
body: <p>I simply tried almost all known ways to enable mixed content in browsers. Nothing works on Mac.
  This <a href="https://pearsonnacommunity.force.com/support/s/article/How-to-display-mixed-content-with-Google-Chrome-Internet-Explorer-or-Firefox-1408394589290" rel="nofollow noreferrer">link</a> provides some solutions that aren't working for me. </p>
  
  <p>Also i tried <code>open -a Google\ Chrome --args --disable-web-security --allow-running-insecure-content</code> without positive result. Do you have any thoughts how to make it work at Mac?</p>
