The only public numbers are from the the previous Google search deal (the one from 3 years ago). It will be a long time until the details of this new deal are public. In the mean time I (as a Mozilla employee) can say that all of the options Mozilla had for the new search deal were better economically than the now-ending Google deal. This was really nice, because Mozilla got to make a choice that wasn't about money, but was about strategy and what we want in the web instead.
