Acid3 Test

Posted in Technicalon Mar 5, 2008

The Acid tests are various tests for web browsers to see how well they can adhere to standards. If a web browser was a computer science project, these would the tests the teaching assistant would run on your project to see how well you did and to assign you a score.

The Acid3 test was recently released, and I ran it on a few web browsers I had installed here. Here is how they performed:

  • Firefox on Windows: 49/100
  • Safari 3.0.4 on Windows: 38/100
  • Opera 9.26 on Windows: 46/100
  • Internet Explorer 7.0.5730.13: 12? (It was so screwed up I couldn’t hardly see the score)
  • Flock 1.1 (based on Firefox) on Windows: 52/100
  • Firefox on Linux: 50/100

I also ran it against Konquerer on Linux, but it kept crashing. Other people are reporting other various scores with various versions.

Update March 7. I’m a little confused about how the tests work. For example, I’ve run it multiple times on the Flock browser, but I’ve seen three different scores come out. I’m confused how the same test can yield different results at different browsers on the same browser. I want things to be more deterministic.

Update March 25. I ran the tests against the new Safari 3.1 on windows, and it scored an impressive 75/100.

Update March 26. Firefox on Windows scored for me today a 53/100.

Firefox 3 beta 3 on my MacBook got a grand total of 59/100, and none of the boxes had any color. Safari 3 got 39/100 and looked totally broken. Opera 9.24 crashed once, and got a very ugly 46/100 the second time I tried. Is there any hope for a browser that actually implements the spec?
