Unless Firefox opens sites instantly (instead of 1-2 sec wait) then I don't see any speed benefit.
I'm gonna go out on a limb and say that the author probably has a lot of heavy addons that do stuff that is not needed. Biggest example probably is AdBlock Plus which bogs down any browser considerably and poking around with family's and friends' Chromes I see that a lot of them have several ad blocking extensions as well as couple privacy extensions is it any wonder Safari or Firefox with no addons is faster?
