Works great. All you need to do is just clicking the "X" that appears on the video thumbnail.

perfect for blocking unwanted youtube channels (https://tubularinsights.com/block-youtube-channels/)

f****** useless, does nothing!

Does absolutely nothing in Firefox.

It was hidding every video, so I reinstalled it and now it doesn't show the configuration section where I could import my block channels.

just doesn't work at all

Thank you very much for this great addon. Could you please add the option to enable/disable | on/off each filter (on the side of the filter) instead of deleting the filter. Thanks again :)

Like many others have stated, this just does nothing. You click "block videos from this channel" and nothing gets added to the settings of the extension.

Doesnt work, my video blocker list is still blank after blocking 10 channels

Review Updates 29/3/2020 - Despite supposedly being updated in February IT STILL DOES NOTHING!!

********

Does nothing but add a pointless item to the right-click menu - completely FAILS to block unwanted channels, and actually seems to cause offending content to be re-fed! Pointless! Don't waste your time!

Не работает чертовщина. Кто знает замену? Или придется самому написать что ли

NE bloque rien sur Firefox nigthly

Appears to no longer work.

Please update this. YouTube sucks ass without being able to block all the clickbait and filth.

Funktioniert nicht unter WIN10 und Firefox.

Несколько лет дополнение работало идеально, н данный момент не работает вообще. Замены нет.

the only blocker i've seen that works with classic layout, but can just randomly break, and delete all your blocked channels and keywords, has no auto-backup of course.
