Title: Improve use of scenes in /firefox/new.

See bug 919788.

This makes a few changes:

* if you arrive on the page directly from #download-fx the animation is suppressed.
* dowload is initiated in an iframe so current page CSS images don't get cancelled before loading.
* scene2 is suppressed on Android
* fixed bug in IE < 9 going directly to #download-fx
* improve inline commenting
* use LESS-CSS mixin for transitions in CSS.
