Firefox seems to be good enough - is there anyone who wants to fork Firefox out of a frustration over how it handles some web standard and a feeling that they could do it better?
Hard forking a browser and implementing all future features on your own is daunting enough that even Microsoft - a company with more engineering resources than all but a handful of others, and for whom having a branded browser is existentially important - decided not to do it and just to reskin Chrome.
So I expect that any truly new browser comes not out of a desire to improve Firefox or Chromium, but from an independent, not economically useful, hacker-driven desire to create something cool. Either Ladybird or someone's RIIR project.
