The following image says it all really:

These past few days there’s been a flurry of WebKit posts over at Surfin’ Safari about its ACID3 performance. I guess when dealing with bugs, and given the fact that Microsoft typically needs around 5 years before simple CSS1 bugs are fixed (as an aside the first and only version of Internet Explorer to date that passes ACID2 is 8 Beta 1, released a couple of weeks ago), I was surprised to see how fast the WebKit developers worked towards passing the ACID3 test. Between 20:22 and 03:51 another three ACID3 bugs were fixed, taking the score to 99/100. I guess by tomorrow WebKit will officially be ACID3 compliant. Woohoo!

By comparison, Firefox 3.0 Beta 4 that I’m using to write this post in Ubuntu Hardy Heron Beta1 scores a somewhat respectable 68/100, although I don’t think they’ll pass ACID3 before the final version is out.
