Considering how little they invest into their core product compared to all the other shit and how much money the top brass earns despite declining market share, I don’t think they’re hurting for money that much.
They are investing a lot in their core product. Problem is that you can’t really monatize it. You want Firefox to be paywalled?
Some of their I initiatives are good, like the built-in local translation tool we now have.
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).
