Screen Shots
These were done with browsercam, so the test may or may not have fully run its course by the time the 15 second delay was up. Still, it’s not like any of these browsers were close, so a few seconds isn’t going to save them if, in fact, they were cut off before the rendering was over.
As a note, I tried to do the Capture in Konqueror and it pretty much made Browsercam cry and/or vomit (“Do NOT Try The Capture Again!”) I’m going to log in shortly to see what the actual damage is.
[update]It’s a known bug and some commentors were gracious enough to take screen shots with updated versions.[/update]

Now, the press release:
Acid3: Putting Browser Makers on Notice, Again. – The Web Standards Project
Acid3: Putting Browser Makers on Notice, Again.
Released: 3 March 2008 | Author: The Web Standards Project
The Web Standards Project (WaSP) today announced the release of Acid3, the latest in a line of tests designed to expose flaws in the implementation of mature Web standards in Web browsers. By making sure their software adheres to the test, the creators of these products can be more confident that their software will display and function with Web pages correctly both now and with Web pages of the future.
The Acid3 Test is designed to test specifications for Web 2.0, and exposes potential flaws in implementations of the public ECMAScript 262 and W3C Document Object Model 2 standards. Collectively known as DOM Scripting, it is these technologies that enable advanced page interactivity and power many advanced web applications such as web-based email and online office applications.
As a series of 100 mini-tests, Acid3 has already been found to expose flaws in all tested browsers, including Internet Explorer, Firefox, Opera, and Safari. WaSP hopes that Acid3 will prove useful to browser makers during the development of future versions of their products.
WaSP has a history of such initiatives. In 1997, emeritus member Todd Fahrner, together with a group of crack Web developers dubbed the “CSS Samurai,” created an “Acid Test” that highlighted shortcomings in browser support for CSS. The Acid Test was instrumental in moving the industry much closer to the goal of consistent rendering of Web pages in different browsers. This was followed by Acid2 in 2005, designed to expose flaws in the implementation of mature Web standards such as HTML, CSS, and PNG. Acid3 builds on and extends this legacy to web applications in 2008.
Acid3 can be found online at http://www.webstandards.org/acid3/

Thanks for posting these. That is some massive fail.
By rob March 4, 2008 - 1:50 pm
No problem. I’m glad to share this kind of thing.
As an update, Hixie mentioned that Safari 3 is now scoring 87/100 on its nightly builds.
By codist March 4, 2008 - 4:00 pm
The latest webkit nightly gets 87/100. I tried it this morning.
By rob March 4, 2008 - 4:04 pm
Yeah, as I mentioned in #2 Hixie wrote about that when unleashing acid3 on the world. I need to source a screen shot and update the post…

By Chris Pine March 5, 2008 - 11:24 am
Maybe try Opera 9.5? It fares better.
By rob March 5, 2008 - 11:35 am
I’m swamped today, but I’ll check out Opera 9.5 today if I get the chance. right now I’m working off of browsercam, but I’m more than happy to expand this beyond the walls of browsercam’s test suite if it’s possible for me to do so.
By Wes Kroesbergen March 5, 2008 - 12:48 pm
The latest WebKit gets 90/100 here.
By Kroz March 5, 2008 - 2:21 pm
Where’s Konqueror?
By rob March 5, 2008 - 2:33 pm
As I mentioned (right before the screen shots start), unpatched, Acid3 kills Konqueror.
It’s a known bug ( http://bugs.kde.org/show_bug.cgi?id=155451 )
I don’t have access to a Linux machine running KDE ( outside of the one at Browsercam) at present, so I can’t do the test myself with a patched version. If anyone wants to contribute a screen shot of a patched version of Konqueror I’ll gladly post it.
By chip March 5, 2008 - 6:09 pm
not mentioned yet, but Internet Explorer 8 beta 1 (released today) for Vista fails at 17/100.

Wow, just more proof IE is the worst main stream web browser out there. I still don’t get why it’s still the most popular.
By Henry 'Pi' James March 7, 2008 - 11:41 am
Does anyone else find it problematic that the official “reference rendering” is not an image, but itself a HTML page? What if a browser fails the reference rendering — but in the same way it fails the Acid3 test?
Theoretically a new web browser can be created in five minutes which passes the test: It renders any given web page to a blank white canvas. The Acid3 will “look exactly, pixel for pixel, like the reference rendering”, as the requirement reads.
By LOL March 7, 2008 - 12:33 pm
one thing i can say – these tests are bullsh*t
By Evan March 7, 2008 - 1:31 pm
Gee, a very early beta (IE8) gets a low score… what a mark against it.
Fizzycakes:
It’s most popular because it’s the default browser for windows.

For what its worth I got a score of 39/100 running Safari on an iPhone with 1.1.4 firmware. While very impressive, this is not terribly surprising since it is after all running pretty much the same Mac OS X and Safari (and webkit) code as on a Mac.
Safari 3.0 under Mac OS X 10.4.11 also gets the same 39/100 score (as previously reported for Mac OS X 10.5).
I also tried a Nokia N95 mobile phone but it completely failed to run the test. This was a surprise since it is supposed to use webkit (like Safari), it failed due to a lack of Javascript support.
A Palm TX running the Blazer browser seemed to get a bit further than the Nokia but also failed to score anything.
Finally, just for laughs I tried Internet Explorer 5.2.3 under Mac OS X 10.4.11 (the last ever version of IE for the Mac) and it also failed to run the test and scored nothing.
I would guess Safari 3 beta for Windows would be scoring the same as the Mac version, anyone tried it?
By rob March 11, 2008 - 8:50 am
I just tested it. Safari 3 Beta for Windows scores the same.
By John Lockwood March 12, 2008 - 12:49 pm
Thanks for the response rob regarding Safari on Windows.
It just goes to show that Apple deliver equally good software for all the platforms they develop for, while Microsoft insist on pushing deliberately inferior versions on anything other than Windows (e.g. MS Messenger, Office, RDC Client, etc. etc. etc. for Mac).
By Greg Haines March 18, 2008 - 2:07 pm
The just released Safari 3.1 scores a solid 74/100 (and says ‘LINKTEST FAILED’). I believe Safari now has the highest score of the Big 3!

Yeah, actually I do too. I’ll have to check the version I tested on at work. They have been adjusting the test over the past few days so maybe we’re seeing a byproduct of that.
