Maybe the ablocker is blocking something and YouTube is repeatedly trying to load it. Also you seem to have multiple youtube extensions, something must have tripped youtube.
You might want to isolate extensions and test if it's a browser problem.
how long did the high usage occur?
I'd also try disabling/removing that "youtube flash-html5" extension. I don't know what is for exactly but sounds like a useless thing.
