title: how to use -moz-focus-inner in ADF to remove dotted outline of button in firefox
body: <p>Here I am using Oracle ADF.
  My button is styled as follows:</p>
  
  <pre><code>af|commandButton:text-only {
      background-image: none;
      width: auto;
      height: 30px;
      border: 1px solid #c4ced7;
      border-radius: 2px;
      font-size: 12px;
      font-weight: bold;
      color: #000000;
      text-align: center;
      padding: 2px 10px 3px 10px;
  }
  
  af|commandButton:text-only:focus {
      background-image: none;
      width: auto;
      outline: none;
      height: 30px;
      border: 1px solid #c4ced7;
      border-radius: 2px;
      font-size: 12px;
      font-weight: bold;
      color: #000000;
      text-align: center;
      padding: 2px 10px 3px 10px;
  }
  </code></pre>
  
  <p>Removed focus outline using "<strong>outline:none;</strong>" as specified in the CSS snippet.
  Now, focus outline is removed in all browsers except firefox.
  As per the diagnosis I found that firefox uses "<strong>-moz-focus-inner</strong>" to render outline.</p>
  
  <p>I tried the following two ways in CSS but no luck.</p>
  
  <p>First way:</p>
  
  <pre><code>button::-moz-focus-inner {
      border: 0;
  }
  </code></pre>
  
  <p>Second way:</p>
  
  <pre><code>af|commandButton:text-only:focus::-moz-focus-inner,
  af|commandButton:focus::-moz-focus-inner {
      border:0;
  }
  </code></pre>
  
  <p>How to specify styles for "-moz-focus-inner" in  ADF ?</p>
