  <p>This is an secured page that I need to access. But I don't know how to obtain its certificate file. I tried to use Firefox, but it says couldn't get any ssl certificate once the url is entered.</p>

  <p>The server is definitely reachable from my laptop. Once I get the certificate file, I assume I can then import it to Firefox and then use my credentials to pass the authentication (I already got the username/password).</p>
  
  <p>Sorry I am no expert in security at all. Is there anything else I can try?</p>
  
  <p>Many thanks in advance. </p>
