Not the developers fault. Youtube changed it's display system and broke this addon - but you can go under your icon on youtube in the upper right hand corner and change to old youtube view ... then this addon will work again. Hopefully the developer here will do an update for the new youtube view.

Used to work, then it stopped. Tried re-installing, and although there are no error messages, it does not seem to block anything even when I use the manual method, and even if I try each of the options. Can't find anything in community support about it either. Thanks, and I will check back from time to time to see if there is a new version.

I was under the impression that this worked. I was sadly mistaken. All I want is to block all videos with the keyword "react" in the title. Why hasn't anyone made something that works like this?

After youtube changed the viewing experience, at least after aug. 17, this stopped working.

I regret so much about making a lowest rate. Actually, one only needs to close the new features on YouTube to get it working. Besides, to import a list, one only needs to find the folder "jid1-3OQ5HY7YsLBV7Q@jetpack" in "\AppData\Roaming\Mozilla\Firefox\Profiles\ipma0ofh.default\browser-extension-data", and revise the file "storage.js" therein.

Thank so much for your hard work, and do excuse my previous rudeness.

UPDATED: it is claimed that both issues have been fixed in the latest Version 5.2.6. Will try it later.

Old review: I'm so sorry to give the lowest rate. It's only working for the first time and then doesn't work any more. I tried reinstalling it but it didn't help. And I can't even import the file, neither by the menu button or by the method suggested on their page.

It is also noted that it's been a year since last update. Is it because of the incompatibility of the firefox update? Could you help look into it?

Anyway, thanks for your effort.

+++++

I sure hope you get this working again. I had to block a heck of a lot of channels, often for click baiting and false information that I don't want to see again.

I've tried importing the "store.json" file several times and nothing is imported. Also, this add-on is still broken when trying to right-click on videos.

Program is awesome. I can barely browse Youtube anymore without this extension. So many shitty Youtube channels, it's nice to block all that garbage. Please... I beg you.... update this for the new Youtube.

Go to your account and turn off new youtube, extension works again! WOOHOO!

All you people giving it one star are total jackasses! It was working great, not his fault Youtube decided to overhaul their site.

Перестал работать, не добавляются каналы в блокировку. Ноль реакции.

Youtube switched up it's layout and no matter how much I press the "block channel" button on Youtube with my right click the app still won't work. It's just not the same constantly clicking "not interested" next to the videos. I want to block out annoying channels that are no longer useful or relevant to me.

I have tried & tried to get this program to work with no luck yet. It does nothing at all for me on Fire Fox. I just gave up on this program & I had to uninstalled it from my PC. Hopefully this gets fixed in an upcoming update for other people who want to use it.

This extension allows you to fully block channels that are bad or unneeded,but you cannot do that with the new youtube style,which is pretty bad. I did not check if you can with the channel manual add feature but it is still bad that you cannot do it as easily or ever on the new style.

What an add-on! One of the most useful add-ons I've ever found. Finally I can block spoilers in YT and can block unwanted annoying channels. But, it's not working with the newer look of YT. You have keep your YT look classic. And for the devs, please I beg to you, please make this add-on work for mobile Firefox, please, please. This add-on is so useful. Thanks a lot guys. :)

I don´t know what people are smoking here, but this is working for me on FF 54.0.1 x64, even while using "Enhancer for Youtube" at the same time.

At first I did try copying the Youtube address and add it to the filter, but that doesn´t work, you have to use the name channel, or just use the right click menu and add it, which is the easiest way to do it.

Absolutely no issues after using it for a month.

Thanks so much, Mr. Developer!

Excellent! Works for me. Where do I donate?

It would be amazing if I could block an entire topic (like 'Sports' or 'Comedy', using the topic tag in the video description) instead of just individual YouTubers. Do you plan a feature like that?

Besides that, it's a great add-on.

Just a heads up that the new YT interface pretty much breaks the add-on. All the stuff you had blocked is now back visible. Giving it a 5* just because it worked for me personally before this. Just hope it can be fixed.

i was relly need it

This used to work really well until a while back it quit working all together. Now it will block the first entry after you delete it and reinstall it, but that's it. Useless currently...

bullshit

I take back the nice things I said, this appears to be stuffed with malware that shows up after reboot. Affected both browsers i installed it in (firefox and chrome) and I haven't installed anything since. Loads a fake FLASH Update screen that takes me to some nefarious site. Uninstalled - Reboot - Ran Defender - Reboot - Problem solved I think.
Combined with troublesome UI and even spelling mistakes, I'm not giving this utility any more chances. I'm sure I can find another tool to do the job.

I tried this add-on version 5.2.5 and it works great! Not flawlessly strangely enough because doing it manually just doesn't work great. But for instance you look for the name of a channel you don't like, you right-click on the channel's name and select "Block videos from this channel" and then you refresh the page, they won't be showing up on the list anymore. It's just perfect. There's some YouTubers I can't stand so I think this add-on works great for that!

Simply does not function at all. Tried manually entering the channel name, and tried the click menu shortcut, and after refreshing the page, then closing FireFox completely, the channel's videos are still showing up in my search results.
