My setup and workflow are unremarkable and will bore you to tears. Linux & Firefox on all my desktops. Firefox uMatrix'ed to within an inch of its life, and with one of those extensions that kill all cookies from a given tab as soon as you close it.. Every now and again I have to temporarily allow one access or another - some sites break if not allowed use of Google TagManager, for example. I keep a seperate profile for a few known sites which I occasionally must use, and which absolutely refuse to function without live access to all the evil empires of the world. My searches go through DuckDuckGo, with a detour to Startpage whenever things don't work out. Oh, and Youtube videos. I never stream. I go there, often via proxy, and I download the thing before watching. For mail, I run all the boring stuff via FastMail, and some personal correspondance through my own server, running on an old discarded thin client with a usb stick for storage. It's a good thing I don't really like the Go language, or I should find myself in a dilemma.
