That really doesn’t solve the problem, like every other Firefox fork they’re completely dependent on Firefox. You can’t just make a new webbrowser just like that, and while third party developers can certainly disable some anti-features, there are limits to that and they can definitely not do the basic work that the Firefox devs do (or could do, if Mozilla had different priorities).
Look into Waterfox instead.
