8 months ago, the add-on stopped working, then the authors worked tirelessly to fix it. It seems that youtube/google/alphabet just can't stand the idea of people having control over the endless disgusting slop oozing out of their website, because an update to youtube has broken this add-on once again.

I see some people saying that only the context menu has broken, but for my part, the entire add-on no longer functions at all. Oddly, the mobile version appears to still be working...

At this point, I wouldn't blame the contributors for giving up on this sisiphean chore. I certainly hope not! I want to stress how good this add-on is, WHEN it's working, in that youtube is so much more tolerable when you aren't being bombarded with gross-out bait videos, propaganda, or 'exclamation and arrow' spam. Sometimes you don't hate a channel, but get nothing but recommendations for that person... and you just want to filter your search results temporarily.

This tool is amazingly versatile, and I think indispensable in taming our increasingly corporatized internet.
