title: Disable cross domain web security in Firefox
body: <p>In Firefox, how do I do the equivalent of <code>--disable-web-security</code> in Chrome. This has been posted a lot, but never a true answer. Most are links to add-ons (some of which don't work in the latest Firefox or don't work at all) and "you just need to enable support on the server".</p>
  
  <ol>
  <li>This is temporary to test. I know the security implications.</li>
  <li>I can't turn on CORS on the server and I especially would never be able to allow localhost or similar.</li>
  <li>A flag, or setting, or something would be a lot better than a plugin. I also tried: <a href="http://www-jo.se/f.pfleger/forcecors">http://www-jo.se/f.pfleger/forcecors</a>, but something must be wrong since my requests come back as completely empty, but same requests in Chrome come back fine.</li>
  </ol>
  
  <p>Again, this is only for testing before pushing to prod which, then, would be on an allowable domain. </p>
