WebKit becomes first browser engine to fully pass Acid3

“Today we would like to announce that WebKit is the first browser engine to fully pass Acid3. A while back, we posted that we scored 100/100 and matched the reference rendering,” Maciej Stachowiak reports for Surfin’ Safari.

“Now, thanks to recent speedups in JavaScript, DOM and rendering, we have passed the third condition, smooth animation on reference hardware,” Stachowiak reports.

“To try it for yourself, grab a nightly,” writes Stachowiak.

MacDailyNews Take: Congrats, WebKit team!

MacDailyNews Note: WebKit is an open source application framework that provides a foundation upon which to build a Web browser. WebKit was originally derived by Apple Inc. from the Konqueror browser’s KHTML software library for use as the engine of Mac OS X’s Safari web browser. The framework is now used by Omniweb, Shiira, iCab, Adobe AIR, Google Chrome, iPhone (Safari), iPod touch (Safari), Nokia’s Series 60 browser and Google’s Android platform. Nightly builds of WebKit are provided for testing purposes only.


  1. Downloaded webkit. Tried the test. The app crashed. Said something like, “can’t use Safari extensions. please disable them.” Looked and looked, can’t figure out what the heck that means.

    It was fast, though.

    Guess I’ll wait for the next Safari version.

    MW: without (how does it know?)

  2. I’ve been downloading the nightly builds for a couple of months now and only now and again will I get the notification of having an extension installed (Safari AdBlock). I just ignore it and keep on going. I drag the WebKit Safari icon (bronze colored ring around it) into the Dock and launch it. Never had it fail and, yes, it does ace the Acid3 test, especially since SquirrelFish Extreme has been included in it. Such SNAPPINESS has never been seen in Safari before!!!!!!

  3. @JES42…. just downloaded the nightly webkit prog, seems to run a bit snappier.

    Lol about pogo – it must be just me. When I open a chess room they crash about half the time.

    Now, back to my meeting. “Hello – My name is Jim – TIV and I’m a confirmed computer nerd!”

  4. Make Safari skinnable? Why? Just USE it, dammit!

    Geee, if that happened how long before the first all black/completely unusable skin appears? I’m taking bets, BTW.

    I installed XP using VirtualBox the other day. (UGH, I HAD to!) Internet Explorer is so horrible looking, I immediately downloaded and installed FireFox. The FireFox fugliness was too much to bear, so I installed Safari.

    Safari’s damn purdy compared to those dogs. It’s a great browser. Why’d you wanna pollute it with some icky skin?

    Seriously check out some of these interface “improvements” people cook up. Yuck!

  5. The one feature I can’t seem to live without now that I’ve used FF 3 for the last couple of months… is page zoom. Glaringly absent from every other browser. It works in both Mac and Win versions, although FF3 for Mac is every bit as nice looking as Safari, maybe even more modern – a vast improvement over their old cartoonish UI. It uses OS native graphical elements now, so naturally the Mac version looks better than the Win version, but both are still leading the pack IMO (extensions… extensions… extensions)
