Earlier quoted context omitted.
You're not wrong, even if it is an unpopular opinion. It's really sad to me as an early internet user. Their side projects have all seemed to fail, and Firefox has never been further behind. I don't see them as being solvent in as little as a few years.
That's too harsh IMO. FF is working absolutely great on my desktops, phone, and as dev browser. And Rust seems extremely popular with a vocal minority on HN at least. But yeah, I'm concerned as well - Mozilla should focus on producing a good browser rather than pouring energy into side projects such as Rust and especially WASM which do not contribute to that goal.
It would be a real shame to lose it.
