title: HTML5 input type number not working in firefox
body: <p>I am using <code>HTML5 input type=number</code>. Its working perfectly in Chrome browser, but its not working in Firefox and IE9.</p>
  
  <p>I want to increment the quantity by <code>one</code> i.e. <code>step=1</code> and also I have set <code>min=1</code>.</p>
  
  <p>I am using the following code:</p>
  
  <pre><code>&lt;form action="" class="cart" method="post" enctype='multipart/form-data'&gt;
      &lt;div class="quantity"&gt;
          &lt;input type="number" step="1" min="1"  name="quantity" value="1" title="Qty" class="input-text qty text" /&gt;
      &lt;/div&gt;
      &lt;button type="submit" class="single_add_to_cart_button button alt"&gt;Add to cart&lt;/button&gt;     
  &lt;/form&gt;
  </code></pre>
  
  <p>Is there any patch or hack to make it work in Firefox and IE9. Or else, what could be the possible solution for that.</p>
