Nowhere there does it say 3.6.6 either. It says 3.6b6pre, which means it's a pre-release version of 3.6 beta 6. The reason it's called Namoroka is because it's not an actual (beta) release of Firefox and is considered unstable (like alphas, but unlike betas). What you're running is not a release, it's a nightly build. Nightly builds are compiled, well, nightly! They are NOT releases.
If they were, they'd be in the releases folder, not the nightly one.
I realize this may be confusing. Also, you shouldn't be running a nightly build in the first place. The only reason you should run a nightly build is if you're a Firefox (or Firefox add-on) developer or are checking for a specific bug.
