I have several Tampermonkey scripts to keep Youtube useable: 
Additionally uBlock, and a plugin to alter the number of results per row (so I don’t wind up with gigantic tiles/icons on a large monitor).
It’s a complete disaster without these. :/
I had one recently that (when changing / creating the password) would allow you paste into the “new password” field but not the “confirm password” field. Super annoying.
I just opened dev tools, pasted it into the “value” property for the control, and kept on truckin’. Just nuts that had to be done though.
Oh man, you’d love this one: https://www.youtube.com/watch?v=PEfNeUdq_C0
