The svg file contains javascript which runs every 2.5 seconds. The javascript makes so many changes to the file that it takes more than 2.5 seconds to process the changes. So firefox is essentially running the script all the time which means you can't do anything else. Note that the script works completely differently for Opera (and any other browser that claims animation support). It does not use javascript to animate the drawing if the browser supports SMIL animation. There is not much that can be done specifically about this particular example. I expect if and when animation is completely implemented in firefox it will just work.
Something similar happens on both Windows and Linux.

Since Firefox 15 we've advertised that we support http://www.w3.org/TR/SVG11/feature#Animation which has fixed this testcase as it now uses the Firefox native SMIL engine rather than the javascript FakeSMIL library.
