Indeed, all of these are in Firefox, in Nightly at least. Though console.profile and console.profileEnd didn't seem to work? I'm sure someone from FF dev tools will turn up in this thread to clarify.
time/timeEnd, profile/profileEnd all work in Firefox up to Aurora -- current nightly has a new performance tool that will support profile/profileEnd in a few days, and will most definitely have it before uplift to Aurora https://bugzil.la/1077464
