ZAProxy Jenkins plug in how to configure browser for ajax spider
<p>I recently started using the Zap proxy plug-in for Jenkins. I am using ZAP version 2.5.0. I have managed to configure this plug-in in Jenkins. Is there any way I can choose a different browser for the AJAX Spider URL(instead of default Firefox)?
    In the standalone version of Zap, there is an option to choose different browsers.</p>

<p>If I use Firefox(version 49) I am getting the following error. So while running from Jenkins I am planing to use phantomjs or htmlunit.</p>
