I agree, but this limited to macOS and iOS. Not helpful to most people.

OP was asking for alternatives in funding, not just straight FF alternatives; I agree that Orion is not, at the moment, an alternative to FF!

/comment posted with FF on Windows

iOS only is for sure a limitation but I've been using it for a while and it's great! Chrome and FF add-ons on iOS including full uBlock Origin.

This is exactly the browser HN has been asking for: no ads, not funded by ads, fully funded by users directly paying them. Fully bootstrapped business with the only funding round they've ever taken coming entirely from their user-base.

Their planned features is a HN wishlist: https://orionfeedback.org/?secondaryTag=planned

I'm sure they're going to sell their default search engine slot to that soulless company Kagi. /s
