According to the new Windows Machine on AWFY and my personal tests on my Win 7, Firefox Nightly is faster than Chrome 32 on Richards.
But on the Mac machines on AWFY, Chrome is faster by a big margin.
Maybe there is a Mac specific problem?
IIRC, Chrome is still 32-bit on OSX, while Firefox is 64-bit on OSX, which could be a factor.
But then the results from Machine 11 (32 bit) would be different from Machine 12 (64 bit), right?

Richards on Machine 11:
Chrome ~25400
Firefox GGC ~20400
Firefox noGGC ~22000

Richards on Machine 12:
Chrome ~24500
Firefox GGC ~17000
Firefox noGGC ~19500

Firefox is slower on both cases, though on Machine 12 the results are worse.
