title: Promise.defer() browser support
body: <p>I am looking for a way to create deferred object which will be resolved outside the current scope. I like deferred objects and as I see <code>Promise.defer()</code> in Chrome 38 returns the deferred object.</p>
  
  <p>But in latest Firefox 34 <code>Promise.defer</code> is undefined as well in Safari 8.0.</p>
  
  <p>So I can't use <code>Promise.defer</code> everywhere now. What about future status? Will it be implemented in other browsers or will be removed as deprecated?</p>
