An honest question: we're seeing many "independent" browsers that are basically a wrapper around Chromium (Brave, Vivaldi, even Edge now) -- does anyone know why there aren't any (that I know of) similar initiatives based on Firefox?
Mozilla doesn't support embedding Gecko these days: https://developer.mozilla.org/en-US/docs/Mozilla/Gecko/Embed...
>Embedding of Gecko is no longer supported. If you currently embed Gecko, you should use an alternate solution, because you will not be able to pick up new security improvements.
They are supporting GeckoView[1], but that's android only.
