Firefox Scores 100/100 on Acid3 Test
Ian Hickson, the creator of Acid3 test, recently made few changes in the test, which resulted 100% score for the open source browser. Hickson posted about Acid3 updates on Google+:
As the Web matures, we have made a concerted effort to improve the precision of Web technology specifications. . It started with CSS 2.1, and then we really ramped things up with the new HTML spec, and now we have broadened the effort to include core DOM features, including DOM Events, DOM Range, and related APIs.
As part of this, we’re trying to simplify parts of the platform that still haven’t received broad use; for example: changing how exceptions in the aforementioned DOM Range specification work, by merging them into the regular DOMException mechanism; making Attr objects not be Node objects; possibly dropping or simplifying SVG Fonts and SVG SMIL animation; dropping XLink; making DocType nodes work more like other nodes rather than being special.
[…] we have updated the Acid3 test by commenting out the parts of the test that might get changed in the specs, including everything I listed above.
Due to this update, Firefox 6.0.2 (most recent release), Firefox 9 nightly, Google Chrome 15.0.874.15 and Safari 5.1 score 100/100 in the Acid3 test. To test it yourself, users can simply visit this page. Remember that the browser must use its default settings to get accurate result, so you should consider trying with a fresh user profile.
With the older version of Acid3 test, Firefox was not able to score 100% as explained here.
