Maybe if Mozilla wasn't so sedated by Google cash they'd be trying things that might disrupt Google's search dominance. There is an amazing germ of an idea in Brave where they push the cost of ownership of a browser from $0 down into the negatives to where you get paid as a user to use Brave. That is a very interesting idea; I'd like a chunk of that advertising money and I think a lot of other people might too.
Brave might not carry the idea to its eventual destination, but there are interesting thoughts there which is more than anything I've heard out of Firefox in the last decade.
