Title: Restore screenshot based app open/closing transition, with mozbrowserfirstpaint \o/

Fix #4367, require Gecko version includes https://bugzilla.mozilla.org/show_bug.cgi?id=787378

The dark semitransparent div which covers the cached screenshot will slow down the transition -- we might need alternative solution for that.
