That would be a good thing. If Firefox is funded by donations, rather than by Google, it ensures there is no enshittification in the future. And yes, donations can fund a big project, as evidenced by Thunderbird and Ladybird.
Nobody uses Ladybird, at this point it's vaporware. And Thunderbird is still based on Firefox. The development of Firefox costs around $200 million per year. That's more than what Wikimedia can get from donations, and Wikipedia is a website that everyone uses. And you want to rely on donations from people that ad-block YouTube instead of paying for Premium. And let's say that it manages to bring those costs down to $…
I am betting this is really paying for the crappy side projects and HUGE pay for the Mozilla Foundation people (just like all the BS spending the Wikimedia foundation does) and has nothing to do with Firefox itself.
