title: Twitter Bootstrap Collapse / Responsive Nav not working in FF / Chrome
body: <p>I made a simple responsive page using Twitter Bootstrap: <a href="http://jsfiddle.net/5YNmm/3/" rel="nofollow noreferrer">http://jsfiddle.net/5YNmm/3/</a></p>
  
  <p>The responsive Nav and any collapse toggles work only once in FF and Chrome.
  In IE they work perfectly.</p>
  
  <p>The collapse example is copied from the bootstrap site:</p>
  
  <pre><code>&lt;button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo"&gt;Press me to toggle&lt;/button&gt;
  &lt;div id="demo" class="collapse in"&gt; Collapsible Content, initially shown &lt;/div&gt;
  </code></pre>
  
  <p>Since i don't include any other js, it shouldn't be the error here <a href="https://stackoverflow.com/questions/11959501/bootstrap-nav-collapse-toggles-once">Bootstrap nav-collapse toggles once</a> or here <a href="https://stackoverflow.com/questions/12231095/twitter-bootstrap-collapse-stops-working-after-first-click">twitter-bootstrap Collapse stops working after first click</a>, where $.support.transition gets overridden by another library.</p>
  
  <p>Many thanks in advance for any advice!</p>
