title: Javascript Blob.slice method cross-browser?
body: <p>Doing a bit of learning about the <a href="http://www.w3.org/TR/FileAPI/#blob" rel="nofollow">Blob</a> type with File access in HTML5 capable browsers and I discovered that Chrome doesn't use <code>Blob.slice()</code> but <code>Blob.webkitSlice()</code>.  </p>
  
  <p>Does anyone know if there is a method for this that is accepted cross-browser yet or do I need to write my own?  </p>
  
  <p>If I need to write my own, can anyone guide me to where this method is defined in Firefox and IE9? (and probably Opera too)</p>
  
  <p><strong>EDIT</strong><br>
  Found the <a href="https://developer.mozilla.org/en/DOM/Blob" rel="nofollow">Firefox definition</a> and it appears that it used to use <code>slice()</code> but now uses <code>mozSlice()</code>.<br>
  So that leaves Opera and IE9+</p>
