title: firefox: how to see text in input fields with black background set in preferences?
body: <p>Input fields don't take over the text color from preferences. The text stays black and so cannot be seen on black background.</p>
  
  <p>It is reported that something like</p>
  
  <pre><code>@-moz-document url-prefix(http) {
      input {
           color: #FF0000 !important;
      } 
  }
  </code></pre>
  
  <p>in ~/.mozilla/firefox/.../chrome/userContent.css should change the text color of input fields, but Firefox 21 has changed userContent.css location. Where is it now on Linux and will this still work?</p>
  
  <p>Recently I found that the Stylish add-on allows to add user styles and adding the above worked. I can use firefox as main browser again. Still the question is, how to do it without Stylish.</p>
