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!
