Disabling YouTube Comments

So... I don't like having YouTube comments show up. So much noise, and almost no signal. It's a mental health nightmare in the best situations sometimes, and I don't want it. Since Google/YouTube won't give an option to turn them off across the site, I looked for a solution.

I found a solution, and I love that it does exactly what it says on the tin. Highly recommend anyone do the same if they want to keep their sanity.
