Works perfectly, exactly what i needeed, i recomend this add-on

A fantastic and vital add-on which has everything you want from a YT content blocker. I tried a number of blockers before, and this one is the best I have tried yet. It has one feature that I've never seen before: it shows you on the page that it blocked something, and why it blocked it. You can turn this "overlay" feature on or off, which I really appreciate. I am very grateful for the person who developed this tool. If you are reading this, thank you!

Fantastic, and practically necessary to wade through modern Youtube. Although, you will have to tweak it in options to get the most out of it. Most people should open the options, and go to the "Overlays" tab and uncheck "Show Overlays". You may also want to go to "Channel", and check off "Add block button next to channel names" for an easy way to block things.

Edit: Looks like youtube is on the warpath again. Much like Channel Blocker and Blocktube before it, the plugin is being supressed by youtube.

Youtubeの検索結果およびおすすめで表示して欲しくないチャンネルやジャンルというものがありますが、それらを幅広く一掃できます。
特定のワードを含む動画を一括処理したり、個別のユーザーを指定して消したりできるので便利です。
チャンネルや動画のみならず、コメントも上記のルールに従って非表示化できるのも素晴らしい。

Extremely useful. It can block channels from the search results.

Great extension, very useful.

This Addon seems to be working in filtering spam comments on youtube. Blocktube seems to no longer have this function and the last update was two months ago and Ublock origin hits the entire comments section instead of a specific comment. This addon has significantly improved my browsing experience and I would recommend this to anyone I talk to.
