HTML5Test is exactly what its name says. We saw no version number, though a perfect score is 555.

For this benchmark, a higher number is better.

Chrome Canary loves HTML5:

html5test_chrome_canary

Firefox Nightly does as well:

html5test_firefox_nightly

Microsoft Edge is getting there:

html5test_edge

Nobody got a perfect score, though Chrome came the closest.

html5test_beta_browsers

Browser standards are a moving target, though this benchmark does show that Google is pushing the envelope.
