title: css media query that targets firefox pc only
body: <p>I want to add a specific style to my page but only on firefox running on a pc. I use this code to target just mac but what would be the windows equivalent? and Is there a way to do it with just media querys not javascript?</p>
  
  <pre><code>var FF = !(window.mozInnerScreenX == null);
  
  if(FF) {
      if(navigator.platform.indexOf('Mac')&gt;=0)
           {
              // is a mac and on firefox
           }
  </code></pre>
