Why Firefox 4 won’t score 100 on Acid3

Mythbusting: Why Firefox 4 won’t score 100 on Acid3 — Alexander Limi.

Acid3 made waves back when being a standardisa often meant being a bit (too) zealous about validation and the like. It was often used as a solid benchmark for browser compliance, and many times I’ll still see references to a browser’s Acid3 score before and after an update.

Firefox has received a slew of slack on this particular issue for quite some time now. It’s great to uncover the truth about it and spread the word about those browsers that do in fact score 100 on Acid3.

There’s something to be said about conforming to test requirements if it means putting real world experience aside and implementing for the sake of the test. Quite an interesting read.
