Maybe if they replaced top Mozilla leadership. Apple had to reinvent itself back into relevance. Mozilla refuses to, and just keeps stagnating in a cesspool of rot and nostalgia. They're less a browser maker these days and more an ineffective think tank. I think Google keeps them around just as a "useful fool" so they can look less like a monopoly...
Probably better for a different org with different leadership to start over. I wouldn't count on Mozilla to miraculously reinvent itself.
