Mozilla has never used the data you upload/send via Firefox to non-Mozilla websites (as it should be), and they shouldn't have that permission just as Epson the company shouldn't have the right to use for any purpose a paper marked as classified just because some fed employee sent a digital copy of it to an Epson printer.
Just read the terms rather than spread misinformation. That data doesn't leave the user's computer.
Do you just not care what happens to Mozilla? How does it help to spread misinformation about them?
> Mozilla processes certain technical and interaction data, such as how many searches you perform, how many sponsored suggestions you see and whether you interact with them. Mozilla's partners receive de-identified information about interactions with the suggestions they've served.
> Depending on your location, Mozilla derives the high level category (e.g., travel, shopping) of your search from keywords in that query, in order to understand the types and number of searches being made.
> Mozilla may also receive location-related keywords from your search (such as when you search for “Boston”) and share this with our partners to provide recommended and sponsored content.
Your claim "That data doesn't leave the user's computer" is simply not true. Mozilla isn't selling empty files to their advertising partners. The only true and valid defense you've put up for Mozilla in the past week is that they're trying to anonymize the data before they sell it, but that's not nearly as strong an argument as you seem to think it is.
You are focused on some concept of perfect confidentiality, which is not how real engineering or confidentiality works.
I'm not interested in your personal comments. Keep them to yourself.
You said "That data doesn't leave the user's computer". It does. You may not consider it personal or valuable and may trust Mozilla's anonymization to be sufficient, but well-written privacy laws rightly do not grant Mozilla (or anyone less trustworthy than Mozilla) that kind of wiggle room.
