Works great! I seem to have mixed results, like it works and sometimes it doesn't, when adding the channel ID or channel name, but I play around with it and it eventually works between the 2. Just erase the text that's there and push enter for the next line of whatever word/channel ID you put for blocking and "save". Thank goodness! Thank you! You have restored relief when browsing videos!

no longer works

Great extension for pc and mobile, however as of recently youtube has done something and the block channel or block video options on mobile are no longer available. PLEASE FIX

Doesn't work with shorts and there is no way to block a channel from the channels page, which means you can't block channels that only have shorts.

doesnt seem to work that consistently (god know why, check the github personally) but it works with another blocker extension so ive just been using this to block spam comments it works flawless for that job

ChannelNameでブロックした文字がコメント欄にまで影響を及ぼす余計な挙動を採用している。
（例："Hik"をブロック対象文字にした時＋チャンネル主がコメ欄で使う名前をHikakinにしており更にコメ欄に何か書き残している場合、その名前がブロック対象とされコメ欄全体や返信欄のローディングがいつまでも終わらなくなる）

これがところどころで悪さをし、非常に使いづらい。

本当にありがたい拡張機能です
PC版サイトだとコメントの3点リーダーにブロックする項目がないのだけ気になりますが本当に助かっています

It does it's job.

Extremely useful and works great for the most part. The advanced blocking seems to break whenever there are certain special characters like pipes "|" in the video titles though; I'd like to see that fixed if possible.

Lightweight, doesn't slow my browser down and generally works well. If it supported blocking videos by categories and tags, it would easily be a 5 star add-on. Even in its current form, it's still pretty good.

I deeply appreciate this extension. I use it regularly and it's been a fantastic addition. My only gripe is I can not find the list of blocked things. It would be great if I can look over them and unblock something if I blocked it on accident. (Which occurs periodically when I'm trying add a vid to my playlist.) Please consider or make clearer instructions on how to do so.

Works perfectly as of feb 28th 2026. Thank you so much for making this addon

Worked for a while. Stopped a week ago after a Firefox update. Developer hasn't fixed anything

Stopped working after a week.

I think there is a bug where when you load a page the addon would not. You have to switch it off/on and it would work.. sometimes.

What a shame coz when it works it works great.

As of 21.01.26 will trigger the youtube ablock detection, must be disabled to view videos

Ein Stern für die gute Idee funktioniert leider gar nicht. Ich habe über die erweiterten Optionen versucht, Kanäle mit null Views bzw. wenig Views zu blocken, aber das funktioniert gar nicht über JavaScript. Hab dann testweise allen Inhalt geblockt, das funktioniert, aber bleibt dann erhalten, bis man die Erweiterung komplett deinstalliert, selbst wenn man die erweiterten Optionen ausschaltet. Also komplett unnütz.

Please add an option to sync the blocked channels and videos across devices to android. The extension otherwise works really well.
