This is hands down one of the best extensions I have ever installed in any of my browsers. It's so good that I decided to write a review for it, which I usually don't care about doing for a browser extension.
I'm paying for Youtube Premium and it annoys the hell out of me that I have to watch sponsored stuff on the many channels I'm subscribed to. Well not anymore. I understand why content creators do these sponsored bits and I support them, but on the other hand f*ck that sh*t. This extension gives you the viewing experience you want.
I also like that it's people like you and me that watch videos, find a sponsored part, mark it and submit. When you come to a sponsored part you can give that someone a thumbs up for their work. It's just cool. Whenever I find a sponsored bit I always do the same. It's like a little game. You just want to find all that sponsored sh*t and let the rest of the world know.
Just download this extension and be a bro!
