Features & Capabilities

YouTube Channel Blockerは、YouTubeのおすすめ欄や検索結果から特定のチャンネルや動画タイトルに基づいて自動的に動画を非表示にする軽量なChrome拡張機能です。チャンネル名でのブロック、タイトル内のNGキーワード指定、チャンネル名横の×ボタンからの即時追加、ON/OFF切替、非表示リストの編集・削除・エクスポート・インポートといった主要機能に対応。日本語と英語のUIをサポートし、切り抜きまとめや不快なサムネ、子どもに見せたくないチャンネルの管理に便利です。

Privacy-first design: all data is stored locally using chrome.storage.local — there is no communication with external servers, no tracking, and no collection of personal information. The extension’s source code is available on GitHub for transparency and issue requests. Perfect for users who want a simple, private way to clean up YouTube recommendations and protect their household viewing experience.

User Reviews

Users broadly praise YouTube Channel Blocker for reliability and a rich feature set, including powerful regex/unicode filtering and multiple blocking options (channels, titles, hidden comments, shorts). It’s seen as effectively addressing harmful-channel issues and is actively maintained. Common requests focus on UI/UX improvements for list management (sorting, saving) and minor filtering edge cases (potential misses or extension conflicts). Overall, it’s viewed as a highly capable tool for YouTube content control.

Pros

Extremely reliable and effective at blocking channels/videos, praised as the most dependable filter.
Rich feature set includes Channel Block Filter, Title Block Filter, Hidden Comment User List, Export/Import, and Short Video Filter.
Powerful regex/unicode language filtering enables blocking content across multiple scripts/languages.
Helps address harmful-channel issues on YouTube and cleans up the feed for a better viewing experience.
Active maintenance with frequent updates and quick fixes when issues arise.

Cons

UI/UX could be improved for easier list management (need alphabetical sorting, easier add/delete, and a save/update option).
Filtering isn’t always perfect and can be affected by other extensions, leading to occasional misses.
Some language filtering limitations remain (e.g., Chinese content can be harder to filter) according to user feedback.

Recent reviews

Is YouTube Channel Blocker Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YouTube Channel Blocker requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

YouTube Channel Blocker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
