title: Alternative to window.crypto.signText in firefox 33
body: <p><code>window.crypto &amp;&amp; window.crypto.signText</code></p>
  
  <p>Since firefox 33 , Mozilla no longer supports this feature.</p>
  
  <p>However there's almost no information about the alternative to <code>window.crypto.signText</code> on the web or is there any at all?</p>
  
  <p>Does anybody have a clue on this matter, appreciate the kind help?</p>
