There seems to be a hype around websites which provide no controls except scrolling like this http://www.mozilla.org/de/firefox/os/

This is a terrible user interface. It is basically a video where you have to scroll for it to play. You keep ending up with half complete animations all the time and sometimes it is really hard to see that you even can scroll. (The above site even provides helpful blinky downwards arrows at times.)

Can anybody tell me what the merit of this method is? Is it just designers trying to show off?

And when did the firefox turn into an actual fox instead of a red panda?
