title: transition for background-image in firefox?
body: <p>I am trying to find an alternative for this: </p>
  
  <p><code>"transition:background-image 1s whatever"</code> </p>
  
  <p>in <strong>firefox</strong> since it only works on webkit browsers. </p>
  
  <p>I already tried the opacity alternative but thats not an option for me since i have content on the background container which will disappear along with the background if using opacity.</p>
  
  <p>Thank you.</p>
