You're a legend for making this! Can finally block annoying channels :-) thank you!

Amazingly efficient. Finally can get rid of the Tsunami of shit results in Youtube's terrible Search.
Thanks so much !

good good

Started using this to block every garbage YouTuber being recommended by YouTube.

It works, is definitely needed. Hope the developer keeps this updated and not give up on it.

YouTube is busy promoting their special YouTubers and pushing even those you subscribe to, below.

FREAKING AWESOME!! Thank you...

素晴らしいです｡ YouTube の不具合 [チャンネルをブロックできない] を見事に解決しています｡ インポート､ エクスポート､ も可能なので､ [ブロックした特定のチャンネルを解除したい] という場合も簡単です｡

========================================

This extension [Channel Blocker] is wonderful. This extension solves YouTube malfunction that "User cannot block channels". Moreover, this extension can import and export a setting file. With that, user can delete channels (that already blocked) easily.

Save me from those irritating youtube recommendations, thanks.

Great addon. Was down for about a day because youtube updated their frontpage, but works again now with latest update.

Thank you so much for this, I've been blocking all of those disgusting stupid comments about Jackscepticeye's dad and all the bots that leave links to random videos, and it's wonderful, thank you so much

OMG. Why didn't I find this addon sooner? I absolutely HATE, HATE those stupid fake movie trailers that keep showing up. It is always the same people, so the ability to block a Channel is AMAZING!!! Now I never need to see "SirMarvel" or any of those other hacks again, so automatic 5 stars. Definitely use this in conjunction with "YouTube Watchmarker", because people should not be getting multiple views unless intentional.

Flawless. If you are sick of seeing certain YouTube channels, give this extension a try.

It works, perfectly. Just what i wanted, you just enter the channel you wanna' block, and that's it, it's blocked until you wanna' unblocked it.

Até agora está ótimo (FF87 64bits). Coisa chata o Bostatube ficar sugerindo coisas de canais que pedi para não sugerir o canal.

😭 😭 It Just STOPPED WORKING !!! 😭 😭
Last FF update started conflicting ( often showed message "extension "ChanelBlocker" is slowing browser") and then suddenly the "X" button beside channels just disappeared 😟
Now all BS from SeweryTube just flooding all kind of trash to my "suggested" column and there's no my main instrument for kicking them out of my eyes... 😭😭😭
I found in "about:config" this bold new mark:
"gfx.blacklist.direct2d.failureid FEATURE_FAILURE_DL_BLOCKLIST_g984"
