My speculation is that this is a compromise in some sense. The change here aligns with what private session is supposed to be. Private browsing will(1) start out with no sessions (none from normal browsing mode), (2) provides automatic tracker protection, and (3) will clear sessions (cookies and history) on exit leaving no trace. Private browsing is great for a number of use cases such as debug/test web app with a new session, visit NSFW, or hide the fact you watch cat videos on your puppy-lover friend's computer. So it makes sense to hide the referrer in private sessions opt-in automatically. As for the normal browsing, you can disable referrer. See [1]. I would like to see more privacy and security options to be shown in the preferences UI. about:config is "okay" but it feels like Windows registry, not good for user experience, even by developer standard when one just want to toggle on/off privacy and security settings.
