Sure, there are forks such as LibreWolf. I understand the reservations regarding Mozilla Foundation, although I generally like what they've been doing. Every org has people with stupid ideas. However, the way I see it, it's unlikely that the community will be able to produce a competitive browser in a broader sense (stability, performance, security, cross-platform...), meaning that the likelihood of Firefox being still around ten years from now is significantly higher than that we build and maintain a comparable browser ourselves. Then come the evolving web standards and lobbying power...
