Using Firefox here since nearly forever, save for a short time with Chrome many years ago, and have never been happier. As for services, YMMV, but Fastmail, DuckDuckGo, Startpage, are widely considered good alternatives for email and search. Other more specific services might be harder to swap with others, but it all depends on which services and how they're used.
