Firefox 3.1 Beta 1 Acid3 Results
After testing Firefox 3.1 Beta 1 on the Acid3 test, the new browser scores an impressive 89/100. This compares to other browsers as follows:
- Firefox 3 scores 71/100
- Opera 9.6 scores 85/100
- IE7 scores a dismal 12/100
- IE8 Beta 2 scores 21/100
- Safari 3.1.2 scores 75/100
- Safari 4 Beta 100/100
This is a great improvement and a step to being fully standards compliant. Mozilla still have some work to go to get to that magic 100 mark, but things are heading in the right direction.

I hope to put the browser through a few tests to see how it benchmarks in both Acid3 and JavaScript tests shortly. Stay tuned…
