Works perfectly on: Webkit Nightly Safari 4 (and iPhone although the user-experience sucks) Icon magnification (animation) works as expected, but some CSS3 for UI are not supported on: Firefox 3.6 and 3.7 (Animation is a little janky) Chrome 5 Opera 10.5 and 10.6 No animation on: Firefox 3.5 and below Not supported: IE in all versions
