While we know that the Firefox OS is coming to smartphones in 2013, what we hadn't seen up to this point were accurate images of what it looks like.
TechWeek Europe, however, has recently shown off a number of screenshots, which it says are the genuine article and representative of the final version.
It's a fairly clean and simple-looking OS. The home screen features tiles rather than icons (nine of them per screen; we're reminded of Windows Phone, but only a little), plus what looks like a notifications bar at the bottom. The camera, messaging and phone apps are totally stripped back.
One interesting shot shows a web browser settings screen showing that Firefox OS will support the same "Do Not Track" private browsing feature as the Firefox desktop web browser.
As we say, look out for Firefox OS next year, but it may well launch in developing countries before heading to Australia, Europe and the US.
