Then pls don’t. Fingerprinting test sites like Coveryourtracks can lead to wrong decisions for many reasons and their way of gathering statistical values is fundamentally flawed. It’s a problem that they don’t show a warning about this.
I get the urge of people to test their browser setup and help with their decision, especially considering the many different recommendations on privacy websites. And I don’t blame them for using these sites, but it’s just exhausting to educate people about the massive shortcomings of these test sites again and again. Coveryourtracks really did more harm than good by not making these clear to the users. It won’t give you a meaningful result about how easy you can be tracked through fingerprinting. And even if it did, it’s just one part of browser privacy and security.
