IIRC there's an option to enable tracking protection in normal browsing on desktop. It's enabled by default in private browsing. (I can't check right now though - it's possible it's just an about:config option too.)
Firefox iOS (on iOS 11+) definitively offers those options, on Android it's private browsing only by default and I don't think there's an option to enable it in normal browsing.
