Works pretty good for me so far, but the filtering can't catch a keyword if there is punctuation or emoji alongside the word. Certain punctuation can be added to keywords to get around this — such as (keyword) — but not all, and emoji always defeat the filter.

Please add a filter to filter ALL Brazilian Portuguese videos great extension I hope you get rich.

Dev is very active, which is AWESOME given how frequently youtube likes to release updates that break extensions like this

excellent, thanks for this it's exactly what I needed.
filters feed AND recommendations, perfect.
also if people read this, delete your youtube history on the youtube page itself, it helps a lot with getting rid of sh*t recommendations.

I feel this extension needs a good rating. I been looking for a simple, straight-forward keyword filter like this. Now I can finally filter out those damn reaction videos (that used to drive me nuts) I don't care about your reaction to something I like, and I definitely don't care about seeing your face in a click-baity thumbnail! Now thanks to this filter they never need bother me again. I tested it and it WORKS. Thank you so much!
