So simple, so effective, no more spam or repetitive junk in my youtube searches. I can enjoy youtube without having to search and search through irrelevant videos and clickbait, or 30 different news channels uploading the same story. Just right click the video, and right there at the bottom, it says "block videos from this channel" so I just click it and done! No more CNN! Hurray!!
It doesn't work with the new youtube layout, but that's okay, because some of my other add-ons don't either, so I had to revert to old youtube anyway.
Also, my CPU and internet signal are crap, and this add-on doesn't affect it a bit. That was the 5 star kicker for me. Very impressive. Thank you so very, very much developer.
