Good Example:

I'm trying to start a youtube video when a modal is opened and not progress to the next page until it is completed.

My script below works in Chrome but produces this error in Firefox and Edge.

Error Message :

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://www.youtube.com/') does not match the recipient window's origin ('http://example.com/').

<script src="http://www.youtube.com/player_api"></script>
<script>
    // autoplay video
    function onPlayerReady(event) {
        event.target.playVideo();
    }
    // when video ends
    function onPlayerStateChange(event) {        
        if(event.data === 0) {          
            alert('Thank you for watching - Click OK to see your results');
        }
    }
</script>

I have reviewed this question/answer but cannot seem to get it working with my code by amending the http / https.
