Panopticlick recommends installing Privacy Badger to Tor users

[ghostwords]

We should not be recommending Privacy Badger to Tor users:

It is strongly discouraged to install additional add-ons, and the Tor Project will not offer support for these configurations.

We're going to simplify the results page in an upcoming iteration. This should show all positive results for Tor Browser, since Tor Browser users are not really trackable due to the implementation of robust fingerprinting protection and first-party isolation. Changing the results page to all-positive results will also remove any recommendations.

@Hainish Here's the code to test for Tor Browser:

function isTorBrowser() {
  return (
    /firefox/i.test(navigator.userAgent) &&

    // Test for presence of anti-fingerprinting features built into Tor Browser

    // Tor Browser rounds the window size down to the nearest number divisible by 100,
    // and also makes the outer size equal to the inner size

    innerWidth === outerWidth &&
    innerHeight === outerHeight &&
    innerWidth % 100 === 0 &&
    outerHeight % 100 === 0 &&

    // Test for time zone hiding (Tor Browser always reports the time zone as UTC+0)

    new Date().getTimezoneOffset() === 0
  );
}
