STR: 1) Load data:text/html,<script>window.onclick=()=>{var x=new XMLHttpRequest(); x.open("GET", "http://mozilla.org", false); x.send(null);}</script> 2) Open the Browser Console 3) Open the Toolbox 4) Select the Network panel and Console panel 5) Click into the page (to execute XHR) 6) Watch the Browser window - no warning should appear.
