  • I'm not disputing the results, but this appears to be checking calls made by Firefox's website (https://www.mozilla.org/en-US/Firefox/) and not Firefox, the web browser application. Just because an application's website uses Google Analytics does not mean that the application shares user data with Google.

    • What do you think what googleanalytics and googletagmanager do and who logs this datas? Only Mozilla? And yes, as said before, Firefox is OK, but not so with an Mozilla account, with which Google said "come to Daddy". I hope that Mozilla, as promised, can end this year the contract with Google.

      • I don't understand what point you are trying to make. Mozilla has several privacy policies that cover its various products and services which all seem to follow Mozilla's Privacy Principles and Mozilla's overarching Privacy Policy. Mozilla also has documentation regarding data collection.

        The analytics trackers that you mentioned would fall under Mozilla's Websites Privacy Policy, which does state that it uses Google Analytics and can be easily verified a number of ways such as the services you previously listed.

        However, Firefox sync uses https://accounts.firefox.com/ which has its own Privacy Policy. There is some confusion around "Firefox Accounts" as it was rebranded to "Mozilla Accounts", which again has its own Privacy Policy. There is no indication that data covered by those policies are shared with Google. If Google Analytics trackers on Mozilla's website are still a concern for these services, you can verify that the Firefox Accounts and Mozilla Accounts URLs do not contain any Google Analytics trackers.

        Firefox has a Privacy Policy as well. Firefox's Privacy Policy has sections for both Mozilla Accounts and Sync. Neither of which indicate that data is shared with Google. Additionally, the data stored via the Sync service is encrypted. However, there is some telemetry data that Mozilla collects regarding Sync and more information about it can be found on Mozilla's documentation about telemetry for Sync.

        The only thing that I could find about Firefox, Sync, or Firefox Accounts/Mozilla Accounts sharing data with Google was for location services within Firefox. While it would be nice for Firefox not to use Google's geolocation services, it is a reasonable concession and can be disabled.

        Mozilla is most definitely not a perfect company, even when it comes to privacy. Even Firefox has been caught with some privacy issues relatively recently with the unique installation ID.

        Again, I'm not saying that Mozilla is doing nothing wrong. I am saying that your "evidence" that Mozilla is sharing Firefox, Sync, or Firefox Accounts/Mozilla Accounts data with Google because of Google Analytics trackers on some of Mozilla's websites is coincidental at best. Without additional evidence, it is misleading or flat out wrong.

        • Don't get me wrong, Mozilla does a lot for user privacy and is certainly one of the most reliable alternatives for a user among the existing browsers. I'm just seeing that Mozilla has unfortunately made a contract with the Devil that prevents it from having the full freedom of protection that it would like. Mozilla deserves the independence of this company, which, at the moment, it does not have, which is why I said that I wish it could end this contract.

          I use several browsers, but the list of existing ones with certain capabilities and functionalities is getting small.

          • Edge is technically a good browser, but certainly not recommended for those who appreciate privacy,
          • Chrome users could ask Google to write their resume directly,
          • Opera is perhaps the worst, using trackers that distribute your data to half the internet,
          • Safari It is not much better either and it is also becoming the new IE with its desire to stay with an engine that is becoming obsolete,
          • Brave is unreliable due to its business with shady crypto companies and the intentional redirections to them and excluding investors from the protections against trackers, Facebook among them,
          • Otter is an alternative, but fighting for its survival, which makes it not very reliable in the long term,
          • the same with some Gecko and Chromium marginal forks, which either lack sufficient equipment for sufficient maintenance, They are directly outdated or lack a consistent support community, - Mullvad browser is very private, yes, but it completely lacks the minimum functions for customization or modification, practically a Firefox left in its bones with 4 sections in the settings.
          • SSuite Netsurf, very fast and beautiful, but not very configurable, it does not even allow you to change the Groot search engine, which on the other hand is good and private, it also does not have extensions, only an Adblocker that it incorporates and it is also only for Windows, the only plus its extraordinary speed and that it works even on very old Windows (>XP) with few resources.

          Well, there's not much left, Firefox, Vivaldi, maybe Otter (if you want speed) and Mullvad, to choose from. The big companies are really destroying a free internet in their greed to control everything and using the user as raw material and merchandise for this. Tough times if we don't manage to stop them. More than 70 browsers have already fallen by the wayside, discontinued and abandoned in this "browser war"
