So this nightly uploaded Build 2 is close enough to RC3 and thus very close to Final...?
Mozilla does true candidate builds. As in they'll spin RC3-build2. If they like it, then RC3-build2
is RC3 (they don't make a new build after they sign off on it--that specific candidate build is RC3. And if they find no showstoppers in RC3, then RC3
is Final. You'll notice that nowhere in RC3 does it say "RC3" because if RC3 looks okay after a period of time as a candidate, it will become Final. Once again, they don't go and spin another build--that specific RC3 build
is final.
Not everyone does it this way (any software maker whose RCs say "RC" need to respin for Final to, at the very least, remove the "RC" from the version string), and every time there's a new major release of Firefox, a lot of people try to upgrade from RC and Final, not realizing that the are literally the same bits.
So
IF no major showstopper comes out, RC3-build2 is literally, bit-for-bit, Final.
