Not sure what you mean. I've tested transitions in Firefox 3.6 and they are not supported - http://jsfiddle.net/qPdeV/ http://jsfiddle.net/qPdeV/

  3.6 doen't support transitions at all, correct. 4 supports transitions, including on ::before and ::after.

    Right. But Firefox 4 is still in beta, making it a bit misleading to say "Gecko is just fine".
