This addon used to be pure gold, however, YouTube must've changed something as it just spontaneously stopped working.
The guy below must be on an ancient version of YouTube.

Massive performance issues that cause constant browser slowdown, and the addon often fails to block content effectively. Genuinely not worth using unless you absolutely have to.

This extension is good for managing youtube channels/videos. Works well.

~ Sometimes channel names aren't recognized and fail to be blocked. This can happen if the name has spaces.

~ Attempting to block a channel while viewing one of its videos often fails. Blocking a channel needs to be done from outside of the channel content to get results.
