My browsing is dpme with a very obsolete version of Firefox running under ArcaOS (OS/2), and no add-ons. I don't think anything like that would even work on this system.
Also, older browsers without modern defenses are subject to fingerprinting, and for your browser in particular fingerprinting is better than a cookie tracker because your setup is so unique.
