Acid2 Test – Firefox 3 Beta 1 vs Phoenix 0.1, Firebird 0.6 and Firefox 2

Have you ever heard of the Acid test for browsers?

Acid 2 is the worst case senario to test web standards compliance. Looking at the source code, it’s by far one of the most convoluted (yet perfectly web compliant) pages I’ve ever seen. I was digging around the Mozilla ftp site and found a really old version of Firefox, called Phoenix and snagged that as well as Firebird.

Phoenix begot Firebird, and Firebird begot Firefox – the browser we all know and love.

Let’s take a look at the results:

Finally, a browser that passes! It’s only been 5 years since Phoenix was initially released, but well worth the wait.
