Don’t get me wrong; their “distractions” have given the world a lot of nice things (Rust comes to mind). But first and foremost, Mozilla’s mission should be to ensure a great, competitive browser, and they’re losing the competition badly. And imho they are prioritizing their resources badly as well.
The one reason that I don’t donate to Mozilla is simply because I feel that my money will be used for vanity ambitions, rather than to the core product. I wish there was a way to donate to Mozilla and say “only use this money for Firefox, because that’s the mission I support, and I don’t really care about the other 90% of the things you’re doing”.
