Obviously Ublock origin, the graal of extensions. Otherwise, the only way I can use youtube these days is with the following extensions: "Hide shorts for youtube", "Youtube search fixer", "Replace youtube's home with subscription". Also "return youtube dislike" and "blocktube" (to block stupid channels youtube keeps recommanding" are cool.

One more general level: I still dont care about cookies, darkreader, bitwarden (password manager), detrumpify (replace trump with a random insult), google sign-in pop-up blocker, flagfox, and many more lol.
