title: Turning off auto-complete for text fields in Firefox
body: <p>Am supposed to be learning French at the moment, but rather than learning any vocab, I've been mucking around with a rails app that tests vocab - so it displays a word, and I have to type its translation.</p>
  
  <p>Unfortunately, Firefox remembers everything I've already type there, so which diminishes its usefulness somewhat.</p>
  
  <p>Is it possible, through the options for form_for or otherwise, to turn this normally useful behaviour off?</p>
