Mac OS X Browser Comparison, Take 2

It’s time for a refresh of the four main browsers on Mac OS X: Chrome, Firefox, Opera, and Safari. These tests will be with the latest browsers as of date of testing as well as the most recent version of Mac OS X.

Test Date: March 29, 2013
Mac OS X Version: 10.8.3 (Mountain Lion)
Chrome Version: 26.0.1410.43
Firefox Version: 19.0.2
Opera Version: 12.14
Safari Version: 6.0.3

Part 1 – HTML5 Compliance

  • Remember, this is not a performance test but simply a test to see how well each browser supports the various HTML5 elements.
  • Compliance is not necessarily something expected to increase in the small .xx releases. This is the case for Opera but surprisingly Safari does manage to make an increase worth mentioning. Even more surprising is that in a whole version release Firefox did not increase its compliance at all. Chrome continues to dominate this realm but increasing an impressive 20 points in compliance rating.

Part 2 – Peacekeeper Test

** The tide has completely turned on this one. Safari showed a strong increase in performance but whatever the folks on the Chrome for Mac team are doing over at Google they should just keep on doing it. Chrome version 26 is a monumental jump forward.

Part 3 – Acid3 Test

  • All four browsers score a perfect pixel-for-pixel result in the Acid3 test.
