<p dir="auto">I just downloaded the most current version of Firefox, it seems the ripple effect of buttons is not working.</p>
<p dir="auto">Just browse to <a href="http://www.material-ui.com/#/components/raised-button" rel="nofollow">http://www.material-ui.com/#/components/raised-button</a> with Firefox, you will see it. The behavior is similar on IE11.</p>
<p dir="auto">On MS edge, the ripple effect works but not very smooth when the React component is updated.</p>
<p dir="auto">I am using Firefox 45 on Linux, and the demo app at <a href="http://www.material-ui.com/#/customization/themes" rel="nofollow">http://www.material-ui.com/#/customization/themes</a> (version 0.14.4) shows that the ripple effect works well for everything but the buttons.</p>
<p dir="auto">That includes the Tab headers, which I suspect are buttons as well.</p>
<p dir="auto">The problem is present with alphas for 0.15 as well</p>
