I consider the internet in 2025 to be more or less unusable without adblock. uBlock Origin is the best I know of, by far. And since Google has forced it to shut down in Chrome (see antitrust), that means I only use Firefox. But even then, the regular uBlock Origin lets a lot of first-party spam through, especially on sites like Youtube. So here's a list of custom rules for uBlock Origin that I use to make Youtube more tolerable. These will remove chat, comments, reels, shorts, and other promoted content unrelated to your actual query.

And some for LinkedIn, now that LinkedIn is mostly promoted content. These remove all promoted and shallow content, so all I get is actual posts by connections, rather than an instagram-like feed of things connections "liked".
