SVG animation ball bounce Mozilla FireFox 3.7 alpha 5 safe

Many of my previous experimentations in SVG animation which run in Opera and Google Chrome are not operational in Mozilla Developer Preview 3.7 alpha 5. The support introduced for animateMotion brings path animation to FireFox. Attempts to use keyTimes and quadratically spaced data points to achieve acceleration failed and yielded a far more complex file. To rerun the animation, reload the page.
