It randomly stops working. I had to reinstall the extension to fix this. Also it grants you very little assurance the video/channel you blocked won't appear again in the form of a reupload or in a clickbait nature.

If you could add the option to black list words maybe this problem would be fixable. For example I keep asking Youtube to NOT show me 'deep house ibiza mixes', I've classified it as non interesting to me, but Youtube doesn't seem to learn I don't care. I use your extension and for a while I don't see those type of videos (because I've manually removed them). Three or four days later there they are again uploaded through other channels. It's useless to use your extension if this hole is present. I imagine this can't be easy to fix but I hope you find a way to manage this issue.

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.

Does not work properly, doesn't filter out recommends or the "explore" section. Kinda pointless now. :/

this addon works, but its UX is poor - you cannot block a channel from the Trending / Main page

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"

thanks for making this, i like to watch military stuff and it has a flood of fake generated videos with robotic voices. thanks for saving my sanity.

I simply cannot understand how YT recommends content for me to watch. Gender reveals, cartoons, football, kardsah!an clan, channels in a foreign language... aargh! Most irritating to scroll through the suggested videos.

And YT itself does honor my choosing not to see these channels anymore.

Well, this extension is the best one I have tried that manages to block suggested channels. I have blocked multiple channel by name, blocked by keywords, and happily report that there is no noticeable slowdown. Most importantly, YT is now watchable again. Well done to the developer, a 5 star rating is deserved.

couldn't imagine youtube without this blocker!
thank you for saving us from evil and bad channels

Edit: Note some channels this add-on wont block you have to type channel name manually!

Works perfectly again, thanks for keeping this extension up to date!

Works as intended. I love how my fan ramps up when I open the homepage of youtube. I even received the "this extension is slowing down firefox" notification once. Watching recommendations disappear one by one is fun. Wish youtube added the block feature. Great job, wish there was not a need for it. Also the ability to sync block list with firefox account would be great, I dualboot and use multiple pcs, I have to sync them up once a week to get rid of what youtube thinks I'd watch that week

Наконец нашел расширение для блокировки каналов без в хода в акаунт! Всем рекомендую!

Thank you so so much!!! I've been looking for a way to hide a user from search results cause it was seriously annoying me due to the way she titles her videos. Finally she is gone.

Needs updating. Stopped working on recommended video list in right-hand column - now only works on Home and Trending pages (neither of which I use). Presumably youtube made some changes that broke it. Now effectively useless for me. Hope they make the necessary upgrades.

only 4 star because unable to toggle it on and off and X button suspiciously missing on "for you" tab

Has started having issues giving you the option to remove a channel on search pages.
