Waterfox is similar, though it doesn’t install additional extensions but comes with a bit of look and feel customization options instead. It restores those non-floating tabs from quantum by default and is pretty speedy.
Waterfox is more for look and feel, whereas LibreWolf makes significant privacy improvements. You can choose for yourself. Btw: You can also customize the UI on LibreWolf, just enable userChrome.css customization under Settings -> LibreWolf -> ‘Allow userChrome.css customization’. Now, you can customize everything you want.
Well yes, Wolf is a lot more focused on privacy, but it’s also a secondary goal for Waterfox. In 6.0 they enabled DNS over Oblivious HTTP (no idea what that means but you probably do) by default and incorporated yokkoffing’s Betterfox preconfig of user.js. It’s for those who are concerned about privacy but not nearly as much as the privacy community. For me, I’d rather have cookies.

It’s basically the standard DNS-over-HTTPS functionality that is already present in almost every browser but routed over a special proxy server. Unfortunately though, Firefox uses Cloudflare services for this.
For me, I’d rather have cookies.
I also have LibreWolf configured to store cookies. It blocks 3rd-party cookies though.
