That doesn’t address the larger complaint your parent commenter is making that Mozilla dropped the ball on Firefox development.

It partially addresses it, because it shows there's a way to save the software Mozilla develops from itself. In other words, I couldn't give a damn if Mozilla keeps misunderstanding it's market if there are open source forks of its software that undoes Mozilla's bad decisions and keeps the parts worth keeping. I'm not sentimental about Mozilla, Mozilla can continue to become irrelevant as long as competition in the browser space continues. New funding models can be developed to support forks of Firefox.
