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.
