Current Firefox nightlies have support for the bleeding-edge CSS transitions specification. […] CSS transitions make it easy to smoothly animate changes to CSS styles, instead of changes taking effect instantly.

Great news! I don’t think there’s a site I’ve done in the last year that doesn’t feature some CSS transitions – which up till now have been Webkit only. I’m less thrilled though about having to add -moz duplicates for all of them though; not great having to write all this fancy new CSS3 4 times over (Webkit, Gecko, Opera and without prefix just in case).
