But my whole point was that they wouldn't be hosting content. The users would be hosting it themselves, on their local computers, serving it via their browser. Mozilla would just have to provide a way to give users a stable base URL (linked maybe to Firefox accounts) that they could give to other people.

Ah... I see, but I don't think it will help that much.

Actually making it work requires proxies and other complexities to cover any reasonable number of users. Those hosted tools take on a lot of the liabilities of user content even if the content isn't directly served.

The limitations will be hard to explain, content disappearing when your computer goes to sleep, or when your browser restarts for an update, or your firewall rules update, etc.

It's also open to abuse without the user's consent, and so Mozilla could become the conduit for hackers, phishing, etc.

Like crypto, I think this is just a dodge. Shifting responsibility to users who don't understand the responsibility they are given isn't an answer. This is hard work.
