(Reply after actually double-checking, also heavily edited) I just went to getfirefox.com, ran the download, and this URL was displayed within tab 2 next to the 'Welcome to Firefox' tab (unfortunately I didn't record which tab was given initial focus) when Firefox started for the first time: https://www.mozilla.org/en-US/privacy/firefox/#firefox-by-default-shares-data-to https://www.mozilla.org/en-US/privacy/firefox/#firefox-by-de... Effective September 28, 2017 [...] Firefox by default shares [...] Interaction data [...] Technical data Since the page you linked was "Last edited 3 years ago" I'm going to specifically contradict what you re-emphasized as fact by stating: telemetry, the feature, has been changed to currently (Sep 2017-present [as of Dec 2017]) be _opt-out_, unless the development of ancient feature capital-T Telemetry somehow still exists separately from contemporary lowercase-t telemetry (per this link also referencing the telemetry documentation). This conversation/investigation/out-of-date documentation reinforces what I see as a very recent trend where Mozilla/Firefox is heading in the wrong direction, basically spending/burning the political capital/trust they've earned while (perhaps unintentionally) deceiving even their most technically adept defenders. I would love to investigate how this approach took root; how it was finally given the official green light; and how its ongoing escalation has affected rank-and-file Mozilla developers, supporters, and the various categories of users. In my opinion, the "spirit of Mozilla" is changing ever so slightly (eerily similar to Google's pro-marketing turn away from "don't be evil" culminating in merging of all collected data). My biggest beef with this is that Mozilla has pushed its public branding further laying claim to protecting privacy, but this could be tempered somewhat with a comparison to Signal's inclination toward practicality rather than perfection. I would be interested to hear how you feel after doubling down on this, since it appears to have indeed changed from opt-out to opt-in without your knowledge. Further, if you did not originally opt-in on install long ago I would be curious to hear what the current value of the setting is now. (Was a previous non-opt-in "default" updated to the new non-opt-out "default" at any point? I hope not!) It goes without saying that you should feel no obligation to invest the time to respond, especially to these last unnecessarily detailed and specific interests.
