This is what you will need in your life tbh, it lets you not only get video's, but also get audio's.

Juhuuu

IT DOES NOT WORK!!

Worked fine for years, but now I'm getting ads about "Mac Virus & Adware Removal by www.y2mate.com" occasionally.

why this add-on collect all website data when it's should be only youtube website?

VERY GOOG.

Very good app

Fantastic addon. Adds a download button just below your video. Also allows you to select the quality you prefer to download. So you can download in 1080p. I have tested 4k or 8k yet.
