As usual, Firefox performance on the v8 benchmark is pathetic where Chrome is more than 10 times faster.It is 24% faster than version 3.5.4 in V8 but it is clearly not enough. In the sunspider test, chrome is 2 times as fast as firefox. In this test, 3.6 is 17% faster than 3.5.4. Safari too comfortably beats Firefox in both these benchmarks. In fact, Safari is running neck-to-neck with chrome on the sunspider.
