I may burn a lot of reputation with my comment ahead, but: I'm a bit tired of privacy-focused web browsers. As you just said, it's not the only use case there is.
What's the differentiation among all of these smaller niche browsers? Can't we escape sameness?
More context: It's not that I don't care about privacy, I do. I'm just fine with some defaults. I don't need (or want) something like Tails. There's some level of privacy that becomes unwieldy to manage.
