title: How can I hide a textarea scrollbar without using overflow:hidden?
body: <p>I want to display a textarea without a scrollbar while maintaining the scrolling behaviour. As the user types I just want the upper lines to disappear off the top of the text box.</p>
  
  <p>I can achieve this in IE and Chrome using overflow:hidden. However, when testing in Firefox 5 on Windows the textarea doesn't automatically scroll and the new text drops off the bottom of the textarea instead of the top.</p>
  
  <p>Using overflow:scroll works well but I need a reliable cross-browser way to hide the scrollbar. Any ideas would be much appreciated.</p>
