Firefox 143.0.0 with TEMP FIX 0.4.6 works fine.
It is a MUST add-on for FF browsing YouTube.
Thanks to developer for all the hard work.
Hope will be updates very soon.

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.

Worked perfectly until it didn't. Has been broken now for many weeks, last code change was eight months ago in December 2024. No communication from devs since then. Project seems to be abandoned.

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

Doesn't work anymore

It doesn't work. You put things in the filters and its like nothing changed at all. Those things you tried to filter still show up in the feed. Useless extension.

no longer works

Used to work, then only kinda worked, now doesnt work *at all*

used to be great but it hasn't worked for a couple of months... which sucks because being able to curate my experience on a website deadset on making my recommended page a psychological minefield really did wonders. youtube really does want the user experience to be as trash as possible.

Used to be great, hasn't worked for months, no apparent updates incoming. Time to find a different extension.

Just completely stopped working for me out of the blue.

Is a must have for me, but out of nowhere stopped working
