Great, would love the ability to hide mixes, and have more videos per column if possible.

love it, the only thing it needs is to change how many videos on the homepage, now that youtube only shows 3 per row (I know this is something available in other addons but why install something else...?)

The extension is chock full of useful features, and they work as advertised. The downside is it causes firefox to have a memory leak when viewing certain pages.

Great extension, i have just one problem, I don't know what I did to the codecs option, but I can't get 1080p for every video anymore.
Whatever option I pick between AV1/VP9/H.264, all of them, none of them, I have some videos stuck at 720p, I have to change and refresh to find the good setting, and then other videos are stuck at 720p...

Almost too good to be true. But so far, it seems it is.

The main reason I wanted this extension was to make Youtube stop spamming already watched videos, random playlists and useless shorts.
1) It doesn't block already watched videos, it just makes them less visible by hiding the thumbnail and dimming their links;
2) Sometimes it marks random videos as watched, but I never even clicked their links, even less watched them;
3) It cannot block playlists, as far as I used it;
4) It blocks shorts successfully AND entirely (not just dim their links).
