Hey Dev, this isnt working at all as it used to. I searched for a term and I got some result which I didnt want so I tried 3 dot and block the channel but nothing happened, refreshed the page, nothing happened, tried blocking the video, refreshed the page, nothing happened. Please look into this ASAP. Also, add sync cloud backup with firefox account as I lose my local backup and with FF account, it will be one list across devices.

Update - Tried checking this on my edge browser (not available on edge addon store so installed from chrome addon store), and it doesnt block anything there also.

So sad. Very useful. Not working anymore.
