Filter out the YouTube videos by the channels you don't like even when you are not signed in to YouTube!!
Just feed in the name of the channel and it will remember to keep the videos out of your sight.
You can always un-filter or unblock the videos by just clicking "Remove" button in the plugin popup. Extremely easy!
This plugin does not track or store any kind of data, user or otherwise, at remote servers!
Remember to turn it on in incognito/private mode!
