No more of those useless unwanted Youtube channels pretty effective.

Works well. Feature request for advanced mode: Support regex for whitelisting. There are so many garbage channels that excluding all except your whitelist is the answer.

FINALLY! After trying out every single channel blocker above this one on the search list, I finally found one that works. now, let's see how LONG it works; before YouTube breaks it.

Just found out it's not compatible with the "restore old theme of youtube" addon. That will break it! "youtube classic" works though.

11/11/2019 The new YouTube update broke it and now the red x isn't showing up.

11/12/2019 Problem solved! Thank you so much to the devs at Time Machine Develpment for taking care of that so quickly.

12/24/2019 A script in the addon is causing firefox to lag. Irritating, but not game-breaking

"X" button does not show up at all

great replacement for video blocker but the only problem is that their is no way to import the 2000 channel i blocked from video blocker to this so i have to block one by one from the beginning

Stopped working for some unknown reason, but now it works after reinstalling

Great add-on. Browsing youtube is fun again.
It's super simple to use and the x buttons are nicely integrated in the site.

Doesn't work ..

Doesn't work most of the times. Sometimes it does, sometimes it doesn't. I just wanted to block videos to certain games that I wanted to play for myself without getting spoiled by some videos (titles and such).

Barely works, completely stopped allowing me to block channels or videos and I was still able to access so-called "blocked" channels. Rubbish.

Works fine on new Youtube but, it doesn't work with Classic Youtube add-on, which makes it pretty useless for me.

its great. my home page looks absolutely amasing ive blocked nearly every talk show host childrens channle and shitty clickbait trash channles and my recommendations have become cleaner

Perfect. I can finally get that cunt Afro's playlist off of my sidebar. After two months, blocking his channel didn't work, reporting and disliking the videos didn't work. But an add-on that puts a simple "X" over the playlist, that fixed it.

Excellent addon. Never had a problem with it, and it nicely cleans up all the stupidity in youtubes recommended algorithm.

5/5 so far for me. However I would like to make a small suggestion. It would be great if exclusions could also be done by video title. There are channels I'm not interested, but I might still enjoy a video they release of a specific subject

This is a great extension so far. Works great !

Not much use... Worked for a day, next morning when the machine was re-booted offending videos/channels were back and the 'X' had stopped working! - It was there, it had just stopped doing anything other than flickering when clicked! - It's also not easy (or maybe not possible) to get it to just tackle YouTube's recommendations without completely blocking channels! - Just, no good... What I really need is a one-click blocker that also sends YouTube the 'not interested' message - and doesn't die after 24 hours!

does not work with classic layout
otherwise would probably be 6+ out of 5
