SponsorBlock does exactly what it claims to, plus it has settings for pretty much everything if you don't like the defaults.

i love you

An excellent extension that has saved me full days of time I would have otherwise wasted on listening to perpetual requests to subscribe and sponsors I'm never gonna buy from.

this extension blows my mind

My old review complained about hooks vs previews/recaps being misused and the devs have made changes to address it. Kind of still wish I could block specific submitters but I can see the effort and improvements.
