Just what I was looking for, works great!

But now I'm left wanting premade/community blocklists, too :p

I wish i could block music videos based on the lyrics. I can't find an addon for that. :/

Doesnt work anymore and seems to be abandoned

Firefox 143.0.3 with 0.4.6 works fine.
It is a MUST add-on for FF browsing YouTube.
Thanks to developer for all the hard work.

Seems to work again after the recent update

Unfortunately has started blocking whole video pages when I try to watch something, had to remove it to be able to view some channels at all.

it worked for me, but now it can not filter subscriptions feed anymore

I can only block channels I've subscribed to.

Used to be great but has not been updated in quite a while and unfortunately no longer works.

No longer works

This add-on has deteriorated to the point it just flat-out does not work anymore. What a shame, since this was one of the best add-ons for making YouTube bearable.

works fine most of the time but seems to flag youtube's adblock detection recently, even if ad skipping is disabled

as others have said, this no longer works.

YouTube changed something, the extension no longer works

Used to work flawlessly to hide videos watched over a set percentage, but now it is non-functional. Big shame

RIP

Was working fine until a few days ago. Not anymore : (

why not remove it when not maintained
