A fantastic app. It saves your preferences across all embedded video formats too (bar a very select few - looking at you Crunchy Roll) which means which means you don't need to reset your speed to 2x every time you delete your cookies/cache, or visit a new website!
I watch all my videos at 2x speed now and I was shocked how much time I saved. It no longer takes me most of the night to work through my YouTube notifications, and has left me so much more time for project work during the week.
Because there are other options like switching off one tab when you start video in another tab, overlay if you scroll down, default quality (I have to be on 144p because of bandwidth constraints)
You can use console in browser to control playback rate:
1. select video element with: $('video')
2. than set playbackRate property on it
example write in console: $('video').playbackRate = 3; (and playback rate would be 3x) Works with rates between 0.0625 - 16.0(tested in Chrome and FF).
