I wonder if there's a security (not privacy) focussed fork of Firefox?
The wikipedia page for Zen Browser, LibreWolf, and GNU Icecat mention security so they'd be a good start. I don't have the technical knowledge to investigate them. I think I'll change to a de-googled Chromium browser when visiting shady sites but stick to a Gecko-based browser for anything mainstream (including Lemmy).
I should probably also do all my banking on mobile and make my security settings on Proton Mail stricter.
Do VPN's actually protect against any of that? They're basically only useful if you want to get around your country's internet filters, log into a website that has blocked your IP, or hide your traffic from the government (and in the latter's case, Tor is probably a better pick).
I guess it may help with tracking, but there are so many ways in which your tracked, is your IP even one of them?
