Started to get this message when accessing Reddit. I use LibreWolf as a browser, which does indeed provide a more generic user agent to combat fingerprinting, but nothing out of the ordinary either (Mozilla/5.0 (Windows NT 10.0; rv:109.0) Gecko/20100101 Firefox/119.0). Anyone else experiencing this?

Edit: seems to have resolved itself. Thanks for confirming I wasn’t doing anything wrong. Let’s hope this isn’t some new algorithm to test if for insufficient fingerprinting so Reddit can kick ad-resistant users.

    It also tells the website the OS you’re running, as well as the browser, and various version numbers of stuff

    While it’s true that many browsers choose to follow a convention that includes that info, User-Agent is just a string, so something like fuku is a legitimate UA

    curl -vA fuku example.com 2>&1 | grep -E '^[<>] (User|HTTP)'
