Even if the Mozilla foundation went bankrupt tomorrow, Firefox would persist. It might not be as quick to update, but it’s an open source project that people will keep working on, regardless of the money.
I've always been curious how many lines of code in Chromium and Firefox are from salaried software engineers, and how many are from community contributions
I just don't like that we're relying on the goodwill (or need for token "competition" to try to avoid antitrust) of Google for Mozilla to stick around, an ad company shouldn't be de facto controlling almost every single browser
I'm afraid to say that there are no such thing as "gratis" software. I guess as firefox user we have to pay a significant amount of money, but I guess that's a dream in open source software community, and the most obvious consecuense is that they are going to find a sponsor
