This is really cool but it actually brings up a question I've had for a while: Is Firefox super slow with graphics? This was incredibly jittery on Firefox for me (my main browser), so I downloaded Chrome quickly to test there... and it ran super smooth. It also ran smooth on my iPad 2.

I'm asking this because I was getting into HTML5 canvas recently, and noticed on Firefox that even a very simple canvas animation is laggy. What's the deal?

Yes, it's laggy on Firefox compared to Chrome and eats all of the CPU (with two cores), so this shouldn't be used on any website. But it looks like it's just updating the positions of HTML elements and it's not using HTML5 canvas.
It was nice and fast for me on Firefox Nightly (31) but slow on the current release version.
For me it's super-slow in Chrome-based Opera, but fast in Chrome and Firefox Nightly on the same machine.

The page's performance might be very dependent on browser's heuristic for conserving memory vs using GPU accelerated layers.

The deal is firefox browser engine is slower than chrome's.Doesnt mean javascript slower per say,but the engine responsible for rendering anything on the screen is.And asmjs or whatever is not going to improve that.
I'm not using any special firefox, but I got a very smooth and slick experience.
Why is Firefox so shit?
