title: Cannot disable CORS policy in Firefox - RHEL5
body: <p>I am running some javascript in my web tool which is using ajax to retrieve some data but I always get 401 Unauthorised error. The server has disallowed cross-origin requests and I do not have access to the server. Now on chrome I can disable the web-security and it works fine. But I mainly need to accomplish this on <code>RHEL5</code> I am running on my machine which has only Firefox since I am unable to install chrome. <br>
  I have tried disabling the <code>security.fileuri.strict_origin_policy</code> and also tried installing <code>cors-everywhere</code> extension. Nothing seems to work. If anyone has any experiece with this please help.</p>
