I fail to understand how they haven’t figured out a way out of this seems to me they’re using all the money they from Google as if there is no tomorrow… Why on earth also if Firefox is so clearly their main product does it seem to not always be at the centre of their attention?
The answer to the second question is the answer to the first - there have been a ton of attempts at alternative sources of funding, but it’s hard to come close to the ~half a billion USD the default search deal provides. So far the branded services you’re calling for don’t seem to have been able to pull it off, and I haven’t seen any signs that donations would be able to either.
(Although as for email with Thunderbird…)
I don’t see how being a non-profit suddenly makes it cheaper to build a secure, modern and compatible browser. (Although I know lots of people underestimate how much effort that takes. But just consider that already Mozilla’s doing it for far less money than Google invests in Chrome, for example.)
