Too bad they don't show in the User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Would love to show the amount of visitors in Simple Analytics dashboards.

They seem to set something on `window.navigator._duckduckgoloader_` If you run `JSON.stringify(window.navigator)`, it only shows the _duckduckgoloader_ variable. Anybody knows why JSON.stringify behaves like that?

  JSON.stringify is outputting the "own, enumerable" properties. The default properties of window.navigator aren't enumerable and/or come through the prototype chain. The rules for JSON.stringify are actually pretty complicated: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#description https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

Brave does something similar. It just looks like a generic version of chrome

  It didn't always have a generic Chrome UA, if you go here[0] it had 'Brave' somewhere in the string, which you could fix by turning on fingerprinting prevention. Glad they fixed that. I don't want people to know I use Brave, although I'm sure there's ways to detect Brave with JS.

    You can do `await navigator.brave.isBrave()` to detect Brave. [1] https://github.com/brave/brave-browser/issues/24478 https://github.com/brave/brave-browser/issues/24478
