Firefox 2 vs Firefox 3 beta 5
May 13th, 2008

| Test #1 | Test #2 | Test #3 | Test #4 | |
|---|---|---|---|---|
| Firefox 3 beta 5 | 15.3 | 51.3 | 135.9 | 48.3 |
| Firefox 2 | 184.5 | 782.8 | 909.6 | 828.2 |
I decided to give a try to Firefox 3 beta 5 and did some JavaScript performance comparison to see how faster it is. I used my own test script that performs object instantiations.
For a more thorough benchmark I recommend using SunsSpider JavaScript benchmark.
