title: Firefox automatically choose certificate, without ui dialog
body: <p>Is there a way to choose the specific default client certificate for authentication on web-resources? In the prefs.js in firefox app data folder, there is a line:</p>
  
  <p><code>security.default_personal_cert</code></p>
  
  <p>I changed its value to:</p>
  
  <p><code>Select Automatically</code></p>
  
  <p>And now it is selecting the first certificate for site avaliable. I want basically to automatate this process (with imacros and few other tools). Is there a way i can set a <strong>SPECIFIC certificate as default client certificate?</strong> Maybe i have missed somethign else?</p>
