title: Firefox redirects localhost to HTTPS
body: <p>There is a similar question about the same issue on Chrome, with an answer that solves it in Chrome. </p>
  
  <p>When I try to go to <code>http://localhost:8000/</code>, Firefox redirects me to <code>https://localhost/</code> . Why? If I open an incognito window, this doesn't happen. I can't continue developing until I solve this. Please help.</p>
