It's called 'Video Speed Controller'. I try to minimise addons but I couldn't get by without it. 'd' key speeds up by 0.25 and 's' slows down by 0.25. It works on videos on most sites, not just youtube. Also handy are Youtube default shortcuts: right arrow to skip 5 seconds forward and left arrow for back 5 seconds. Tap them a bunch of times to skip product placements or long intros. Just a warning when you use these a lot it will make regular TV unbearable (if it isn't already).
