Moltres can't be found in Crystal. If you want it in Crystal, you'll have to use the Time Capsule or you could get it from an event in the past. You can find Moltres at Victory Road in Red/Blue/Yellow.
You can't find a Vulpix in Pokemon FireRed version. That pokemon is version-exclusive to Pokemon LeafGreen.
