Firefox worked great for a few months after the big fuss over Quantum coming out and then went right back to just being a browser for enthusiasts and privacy activists. And that's after that whole dumb advertising push they did with billboards reading scary stuff like "Big Browser is watching."
If anything, Firefox is a good example of why it's probably better for aspiring browser competitors to start off by just spinning off from Chromium like Brave did. Not that Brave is perfect either, especially not on desktops, but the saved resources let them focus on finding ways to surpass the competition like improving the mobile ui.
