I just tested Acid test 3 on different browsers installed on my Windows 7. Only 3 browsers were able to pass acid Test 3 with 100 score.
1. Google Chrome 6
2. Opera 10
3. Safari 4
IE9 and Firefox 4 are currently in beta phase. Beta version of both browsers failed to score 100 / 100. I hope to see them giving 100 score in their final version.
