when doing tracing and jit, firfefox js is faster than other js engines, however, when tracing fails, tracemonkey (firefox's current js engine) falls back to pretty old fashion way which is quite slow.
Mozilla is now working on JaejerMonkey, which will supposedly take advantages of tracing, plus generic approach as observed in other engines.
We shall see.
At this time, Opera 10.5 seems to have find a secret of js performance and its js is absurdly fast, I would be interested to compare the two when JaejerMonkey lands.
