and when you need something between 1.25 and 1.5 available from UI, you can always do:

  document.getElementsByTagName('video')[0].playbackRate = 1.35

Nice hack. I always found 1.25 to be "too slow" for watching something but 1.5 to be way too fast and annoying.

I've as a habit downloaded videos manually just to speed them up. When watching a video for it's information, I can usually, and not uncomfortably listen to it at around 1.7-1.8 depending on speaker. It takes a little getting used to though. I'll say that.
