OMG this, combined with uBlock Origin, makes Youtube actually bearable. THANK YOU SO MUCH!

No more james charles!! thank you!!!!

Edit: doesn't block things from showing on home page

It used to work nicely, but since the latest YT changes, the blocked channels show up in the trending section and whatnot. It's now nearly useless.

Super rozszerzenie,w końcu raz na zawsze można zablokować te gówniane kanały co mi się non stop wyświetlały

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.
