Librewolf does this. It's a patchset for Firefox that removes all the bad stuff and makes a bunch of security/tracking improvements. It fakes your agent, timezone, screen resolution, disables a bunch of APIs that can be used to track you, etc. It _does_ break some websites, but I just use another browser for those one-offs.
