It’ll be next to impossible when those websites are your bank and Netflix etc.

Time to De-Google I guess. I will keep using Firefox and if or when I come across any website pulling this crap I won’t hesitate to blast them to eternity. I suggest everyone else do the same please.

Google is actively trying to drive people like me away. I have been trying my hardest to keep using Android, if Google keeps this up I might have to unwillingly move to Apple. At least they do more than just pretend to care about their users’ privacy.

Yes, but the idea is that because the code is open source anyone can look at it and determine on their own whether it is in fact safe or not. Generally speaking the open source community is very good at figuring this kind of stuff out but I would say your fear is not necessarily out of place since nothing is 100% guaranteed. That said though, the more popular FOSS apps are quite safe.

Oh! true, completely slipped my mind. Install it in another PC or use an M.2 enclosure with USB C to partition it and clone the original.

I don’t own a Steamdeck myself but since it’s Arch Linux based there should be a partitioning tool like GParted built in.

You may want to check if it is partitioned.
