Firefox died long ago.

It was an engine fight, and Mozilla decided not to participate.

The Kia Niro is pretty close, although if you’re really serious about making it dumb you’ll need to pull the cellular modem. It doesn’t depend on any internet services, but it does connect to the internet to get nearby charger data.

I’ve got a couple VPSes, hosting

• Mailcow, because email is identity.
• Asterisk, because phone #s are also identity.
• Matrix-Synapse, for personal messaging even though XMPP is probably better.
• ttrss, even though it’s junk software with a jerk developer.
• A bunch of self-developed web apps

Self hosting email is obnoxious, but it’s also one of the only remnants of the traditional distributed internet that’s still broadly accepted.
