EBlog recently showed the Mozilla blog some Sunspider results that show them currently ahead of Firefox. Below are the results that the Mozilla blog guys got when they ran the test.

The graph basically shows Firefox is a shade faster as of now, and they claim to be working on more fixes to increase the speed further. However, as you can see, Chrome/Chromium is still ahead of the pack. The main goal of Chrome seems to be to increase the speed of browsing on the web.
