Does anyone know if the PPA/Personal Pan Pizza Privacy/Whatever thing has an about:config entry or is it controlled from about:preferences#privacy?
EDIT: To answer my own question, the about:config entry is "dom.private-attribution.submission.enabled" which should be set to "false"; for those of us who use arkenfox, you should add this to your user-overrides.js file and then run the updater:
user_pref("dom.private-attribution.submission.enabled", false); // Disable Privacy-Preserving Attribution
This is correct AFAICT.
EDIT EDIT: Also, possibly naive question: Why can't Mozilla/Firefox just ask for donations like Wikipedia does instead of sneaking around, which they sort of seem to do once in a while?
