タイトルを並べるのに、小ウィンドウに依然入れたのがそのまま残っているのが気になる。
追加削除は設定から開いた大きな画面から出来るようにしてほしい。

Seems to work nicely. A nice addition would be to sort the names in the list by alphabetical order to easy find it back and remove it from the list. So also implement a save button to update the json file.

An app that actually works deserves five stars, after so much deception.

今まで YouTube の有害チャンネルのブロックには [Channel Blocker] と [BlockTube] が存在していました｡ しかし､ どちらも 2025年09月29日現在では正常に動作しなく成っていました｡ YouTube の仕様変更が原因と言われています｡ そのため､ YouTube の有害チャンネルをブロックできない状況が継続していました｡ そもそも YouTube 運営者が有害なチャンネルを削除するべきなのですが､ 全く仕事しない YouTube の運営を待っていても仕方有りません｡ そのため､ 即座に YouTube Channel Blocker を入れるべきです｡

Until now, [Channel Blocker] and [BlockTube] existed for blocking harmful YouTube channels. However, as of September 29, 2025, both had stopped functioning properly. This is reportedly due to changes in YouTube's specifications. Consequently, the situation where harmful YouTube channels couldn't be blocked persisted. While YouTube's operators should be removing harmful channels in the first place, waiting for YouTube's completely ineffective management is pointless. Therefore, you should immediately install YouTube Channel Blocker.

こまめなアップデート、お疲れ様です
とても助かります

After trying a dozen addons like this when youtube changed a few months ago and made them stop working, I found this one and its excellent. Does exactly what I want and hides channels I don't want to see. It stopped working a few days ago and was fixed in less than a day. Absolutely recommend this one, check it out.

edgeで非常に良かったのでfirefox乗り換え後も入れたのですが、firefoxだと何故かほんの少しだけページを広げるようで左右にスライダーが表示されます。
これのせいで矢印キーで早送りすると画面が動いて邪魔くさいです。

Thank you for making this extension

Fails to block some filtered titles even though the filter keyword is exactly as it appears in the title - case and all.

UPDATE:
It is possible that another extension (which I have since uninstalled) could have interfered with this, so I'll up my rating from 2 to 4 stars.
I stick to 4 stars and not 5 as the filtering is fairly limited compared to some other extensions I've used before but are sadly no longer being maintained. Regex filtering would have been awesome.

Works very well, thank you for your contribution...

Easy and explainable screenshot, and fast language shift to get ahead of the understanding.

Very well done <3

素晴らしいです！凄い快適に使えてます。
老舗のChannel Blockerが使えなくなった人は次はこれを使いましょう！
