It’s curios if you used Prometheus as well

you would. the alternative would be a vpn when you’re on the go

travel router. I use this one. Though the right travel router will depend on your home network configuration.

Privacy is about reducing your footprint, not erasing it. We’re not spooks. If you use the internet in any kind of capacity, for content, or shopping…there will be some kind of record of you. You just want to reduce it.

Get rid of noscript. 99% of the internet needs javascript to work. Stick with Librewolf or some kind of Firefox based browser using UBlock Origin. If your super strict Librewolf settings are breaking certain sites, ease up on them until you find it tenable. You don’t need Tor. Tor has always been slow.

Get an extension called Privacy Badger.

Two things you should do that wasn’t mentioned in your OP:

1. Manage your own DNS. I use Technitium, but AdGuard and PiHole are 2 other options that do the same thing. Managing your own DNS is a big privacy win especially when you’re not on a VPN.
2. Buy a domain to manage your email. Using the same email address on different accounts is a big privacy issue. Companies hash emails and pass them around. So if you use your email address for an account on Company X site, and also on Company Y. Y can send X a hash of your email, and they can see that you have accounts on sites X & Y. And then boom, serve you ads related to them.

If you have an domain associated with an email, you can create addresses at will when you make accounts. So in this scenario, you’d have companyX@mydomain.com, and companyY@mydomain.com. The hashes wouldn’t match. And if you only use that email for that one site, you’ll never be cross-referenced.

Would a Roku work? Forgive my ignorance, not sure if they count as android based

Per an article from last week, she hasn’t “ruled it out” but hasn’t committed to it either.
