Finally I found a extension that work to block youtube channels :'D

Amazing.
And it does not even requires the "access your data for all websites" permission.
Thank you very much amitbl.
Youtube, or Firefox, should hire you just to have this feature :)

When used with uBlock, blocking from the dropdown menu may not work work - the dropdown menu does not expand, depending on the filters enabled in uBlock. This is not the developer's fault, so please stop blaming him in the reviews.

Additionally, it works ok when channels are manually added on the settings page.

Works as advertised. Straight up blocks videos/channels right out of your eye holes.

It does what it says on the tin well, but doesn't do what I had intended to use it for well.
I had intended to use this to fine tune my recommended section in the home page, blocking the channels I was already subbed to (thinking they'd be left alone on the subscribed page), but this addon straight up removes everything without prejudice. I'm not faulting it for that, as it's doing what it's meant to be doing. I just wish there was a way to use this how I had hoped to. In any case, it'll work fine for blocking channels I have no intention at all to watch.

Works as expected

Works well since last year. Stopped working today.

Thanks to BlockTube I've been able to turn OFF AutoPlay & eliminate a couple of youtube channels I don't want to watch

Does not work.

Awesome work! Keep it up.
I have never rated anything pretty much, but I made myself a firefox account just to comment to you, that I really appreciate this extension.
Muuuuch appreciated!

Works GREAT!

Useful Add-on, works well for me, but it would be cool if different YT-accounts could block YTer, separate.

Simple, easy to use.

Im updated my review, this is essential addon for people watching a lot of videos on YouTube. When addon stopped working...well, glad it worked again.
