Notice the major scale only contains one tritone or augmented 4th. I find it's easiest to flatten the index finger and shift positions for each interval, but add the middle or ring finger for the tritone.

Very similar - only one tritone or diminished 5th (the fingering is the same as the example for 4ths). Again, it's easiest to use the index and ring fingers to make the perfect 5th shape and shift positions as you move up the fretboard, switching out the ring finger for the middle finger (or moving the ring finger back a fret) when you reach the tritone.
