Firefox achieves 314 and nine bonus points. Safari demonstrates 252 and two bonus points for fourth place, while IE9 is in last place with a score of only 141 points and five bonus.

FutureMark Peacekeeper 2.0 HTML5 Capabilities
FutureMark's new version of Peacekeeper also has an HTML5 conformance measurement, known as HTML5 Capabilities. The maximum score is seven, and Google Chrome is the only browser from either platform to earn a perfect score, sealing its victory. Firefox attains a six out of seven to place second, while Opera manages a score of five, putting it in third place. IE9 comes in fourth place with a score of three.
Although Safari for Windows only gets a single point, Safari for OS X earns four.
Google Chrome once again tops the conformance composite with the only A (minus) grade out of the bunch. Firefox 9 lands a solid B grade, while Opera shoots up to a B-. Both IE9 and the Windows version of Apple Safari land an embarrassing failing grade, although Safari manages a C- on OS X.
