One of the most impressive features in Google’s open source Chrome web browser is V8, a high-performance JavaScript virtual machine that was developed by a team of specialists in Denmark. Although Chrome’s performance beats the current stable version of Firefox, benchmarks show that Mozilla’s next-generation JavaScript engine actually outperforms V8.
i'm still not convinced of FF3, the interface runs much slower and i sometimes get "hang times", split seconds, where i cannot click or do anything, it seems that the application has crashed. though on linux, it works nicely.
