Ask HN: What would be a better business model for browsers?

Mozilla published about $500M in royalties revenue "earned through Firefox web browser search partnerships and distribution deals around the world" [1] in 2016 against ~900M active clients [2]. Which means browsers as a business model currently approximately monetize at around $0.55/user/year. This is done by search engine partnerships, default bookmarks and distribution deals. Is this good or bad? What if you wanted to build a browser around speed, privacy, ad/tracking blocking features?
