great, but why not open source ?

It makes it possible for me to hear! They have helped the hearing impaired be able to watch YT. Thanks guys!

Suuper duuper amayzing

EXCELLENT

me gusta, agrega funciones y tiene opciones para las opciones de la pagina de youtube y por ejemplo; si tenemos musica podemos amplificarle el volumen

Extensão maravilhosa. Acabou-se os anúncios infernais! Nota 1.000

The best so far. I've being using it for a very long time and I do think it's a great one. Thank you! <3

How many YouTube things have I installed over the past decade. Ad blockers, other YouTube things and then someone mentioned this tool. It has mostly everything I am looking for. I am using Firefox now, have been a Chrome user for a long time but I am so done with Google and their constant tracking and wanting payments so people can still tell me all about their sponsor. Great extension, I find new things almost every week. I love the picture scaling while reading through the comments for instance.

It's not open source...
