Ad blockers :)

Why isn't there a browser which you can just install to have a good Internet experience? It would have to update itself every day with a new definition of "good" due to the arms race with advertisers.

It would have to block all ads and trackers and other bad JavaScript; automatically redirect YouTube to Invidious and so on, while seamlessly keeping all YouTube features; automatically open the chronological tab instead of the recommended tab on most social media; be blatantly illegal to possess; and update itself through Tor so nobody can do anything about it.
