It was at the Securedrop website. How did I end up there ? I read something about Sequoia and encryption and then wanted to see what Securedrop entailed.

Meanwhile I’ve raised the security settings. Still, today someone in this community (?) mentioned that Tor browser does not protect the remote to check for the OS, and now this. Color me surprised.

    Here some proof of my claim that Tor browser useragent string is Windows : https://wiki.archlinux.org/title/Firefox/Privacy#Change_user_agent_and_platform

    Tip:

    The value Mozilla/5.0 (Windows NT 10.0; rv:102.0) Gecko/20100101 Firefox/102.0 is used as the user agent for the Tor browser, thus being very common.

    From five years ago, afaik suggesting Windows is the default : https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/26146

      Tor browser from the arch repos is not stock torbrowser. Add repos for torproject/guardian project/whatever it’s called now, or use the torproject.org installer.

        Are you saying that Arch Linux is providing Tor browser with a different useragent string ?

          I believe that is the case, if you inspected the HTTP headers and found if to show Linux instead of Windows. my last experience with that would have been years ago. Arch does like to compile things from source instead of using binary blobs, and compilers and configs can undo a lot of the work the torproject has done to combat fingerprinting, which is why it’s recommended to run the pre-built binary and install no plugins. However it’s important to note that it ALSO gives you a unique JavaScript fingerprint every time, when tools use as much information as possible to generate a fingerprint, because it generates new information on every reload. That’s why OPSEC is important and for can’t help you if you use it wrong. If you login to 2 different unlinked sites in the same session, and you don’t want them to be linked, too bad now they’re linked via JS fingerprinting. JavaScript is more or less a programming language within the browser, and you’ll never escape JavaScript fingerprinting. Which is why it’s important to learn how to use tor properly, and leave JS disabled as much as you can.

          One thing you can do with your arch build is use the fingerprinting tool to see how unique you are, then get a new identity, then go back and do it again. Does it now say you’re one of 2 people who have used the tool, or does it show you’re (again) unique? If the latter, then it’s working (at least enough) properly.

            Interesting. I would have expected the useragent string to be part of the user configuration files that are automatically created in the browser profile directory. I’ve not used Tor browser package from Arch yet but curious to do some testing.
