Mozilla's Updated ToS: We Own All Info You Put Into Firefox 98

        Pale Moon isn't great, to be honest. They insist on sticking with the old XUL based add-on system, so the whole browser has to be single threaded and slow. It's also a huge security issue, because as well as making it impossible to sandbox parts of the browser like FF and Chrome do, it means that every add-on is also a potential security vulnerability as well because it runs in the browser context.

    It seems ridiculous and invasive on the face of it but I'm guessing Mozilla's lawyers are looking at the UK Online Safety Act, similar bills introduced into US state legislatures with a non-zero chance of enactment, and talk in the US Congress of repealing Section 230 and telling their executives that the operation of the browser - which by nature does see and pass all the information the user exchanges to/from the rest of the world - could be construed as being an accessory to violation of those laws and upcoming laws. A more extreme version of photosharing sites needing some sort of license to your work to be able to display it.

      That's what I was thinking too.

      It doesn't help that ToS documents are written in 'legalese' which means they always use awkward and annoying language. Hopefully someone will learn from the uproar and use plain language instead. Like:

      When you enter or upload information in Firefox, the browser only uses it to help you browse the web, like finding and showing websites based on what you do in Firefox. This does not grant us any ownership or broader rights over your information.

      The first part is pure bullshit, the second part is hilarious. I suggest you read their "privacy note", which starts with "we can't do bad things, unless it's specified in there" and then goes on specifying it in there.

    Quite a while ago I configured my firefox up to a squid server. I polled the logs for mozilla addresses. Every now and them I will just fire up firefox and let it sit idle. If any of its many telemetry calls are not blocked I add it to my custom pfblockerng block list. I got tired of them deciding I needed to restart and crashing my tabs. Now it only updates when I update the machine. Along the way I blocked all the addresses it attempts to contact. Same with google. Sure its requires maintenance but at the end of the day I block anything on my machine I dont want from accessing the internet. No pocket or any of that crap. At one time I had the addresses for the addons blocked. Don't give them an option.
  • Mozilla is supposed to be the champion of data privacy. Why in the world would they put this into their clause? This literally means that they can take data from your account as well as passwords and use them indiscriminately. I'm cancelling my mozilla account and switching browsers and you should too.

    UPDATE: We’ve seen a little confusion about the language regarding licenses, so we want to clear that up. We need a license to allow us to make some of the basic functionality of Firefox possible. Without it, we couldn’t use information typed into Firefox, for example. It does NOT give us ownership of your data or a right to use it for anything other than what is described in the Privacy Notice.

    We’re introducing a Terms of Use for Firefox for the first time, along with an updated Privacy Notice.

    Why now? Although we’ve historically relied on our open source license for Firefox and public commitments to you, we are building in a much different technology landscape today. We want to make these commitments abundantly clear and accessible.

    While for most companies these are pretty standard legal documents, at Mozilla we look at things differently. We lay out our principles in our Manifesto:

    Your security and privacy on the internet are fundamental and must not be treated as optional.
    You deserve the ability to shape the internet and your own experiences on it — including how your data is used.
    We believe that practicing transparency creates accountability and trust.

    Firefox will always continue to add new features, improve existing ones, and test new ideas. We remain dedicated to making Firefox open source, but we believe that doing so along with an official Terms of Use will give you more transparency over your rights and permissions as you use Firefox. And actually asking you to acknowledge it is an important step, so we’re making it a part of the standard product experience starting in early March for new users and later this year for existing ones.

    In addition to the Terms of Use, we are providing a more detailed explanation of our data practices in our updated Privacy Notice. We tried to make these easy to read and understand — there shouldn’t be any surprises in how we operate or how our product works.

    We have always prioritized user privacy and will continue to do so. We use data to make Firefox functional and sustainable, improve your experience, and keep you safe. Some optional Firefox features or services may require us to collect additional data to make them work, and when they do, your privacy remains our priority. We intend to be clear about what data we collect and how we use it.

    Finally, you are in control. We’ve set responsible defaults that you can review during onboarding or adjust in your settings at any time: These simple, yet powerful tools let you manage your data the way you want.

    You deserve that choice, and we hope all technology companies will start to provide it. It’s standard operating procedure for us.

    I've been using my firewalls as a form of mitigating control to keep Firefox from leaking anything. Once I download Firefox and get my extensions loaded, I block everything mozilla and log all other requests. I'm using host based firewalls (little snitch), and the firewall functions in my ubiquiti router. They can try to collect data but won't be able to exfiltrate it.

    When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox.
