They fixed some things partway through the process with the compact theme - the address bar is now shorter while the tabs + their padding is taller than the tabs in old compact mode. I haven't done a side by side but I think compact -> compact ends up being a wash in vertical real estate. There were some older images where new compact was taller than old normal and new normal was taller than old touch when it was in firefox beta however.
