title: Which HSTS preload list is used by which browser?
body: <p>I've been reading various informations about Google and Firefox using an HSTS preload list.</p>
  
  <ul>
  <li>it seems that there is a generic list here : <a href="https://hstspreload.org/" rel="noreferrer">https://hstspreload.org/</a></li>
  <li>and that Chrome uses the one from Chromium here :
  <a href="https://www.chromium.org/hsts/" rel="noreferrer">https://www.chromium.org/hsts/</a></li>
  <li>and Firefox uses the one here :
  <a href="https://dxr.mozilla.org/comm-central/source/mozilla/security/manager/ssl/nsSTSPreloadList.inc" rel="noreferrer">https://dxr.mozilla.org/comm-central/source/mozilla/security/manager/ssl/nsSTSPreloadList.inc</a></li>
  </ul>
  
  <p>Does Safari or Opera use a HSTS preload list ? Which one ? What is the relationship between the 3 list cited above ?</p>
  
  <p>Thank you</p>
