title: How to inject Javascript to https sites?
body: <p>I have a project that I have to inject Javascript into websites using the browser. I mean that I go to developer tools -> console -> enter the following: </p>
  
  <pre><code>window.FO_DEBUG=true; 
  var b=document.getElementsByTagName("head")[0].appendChild(document.createElement("script"));
  b.src="//path-to-file//"
  </code></pre>
  
  <p>The issue is that I cannot inject code from my local machine for HTTPS websites.<br>
  The only way I found to do it is to inject a file from <em>another</em> HTTPS server.</p>
  
  <p>Do you know any way of injecting a file from my local machine to an HTTPS server?</p>
