title: Zed Attack Proxy Dynamic Certificate Won't Import To Firefox
body: <p>The last time I did a scan (on OWASP 2.4.0 using Firefox version of the same timeframe), I was easily able to generate the dynamic ssl cert, save it (as a cer) and import it to Firefox. Now, with ZAP 2.7.0 and Firefox 51.0.1 it doesn't work. </p>
  
  <p>Now, Firefox is griping about "This personal certificate can’t be installed because you do not own the corresponding private key which was created when the certificate was requested." I am no ZAP, or certificate, expert, but shouldn't this work? Chrome and IE don't complain about the cert, but they do silently fail to import it. Which means I can't do the scans I needed to get done... By tomorrow...</p>
  
  <p>What am I missing?</p>
  
  <p>Thanks!
