What every browser knows about you

A browser reveals more information about you then you probably know: location, software versions, currently logged in services,...

You will be really astonished how much information this is.

Browsers like Firefox, Chrome, Safari and Brave have plugins that help with blockers and cookie control, these may help you.

  • Try to use the same link with a browser in privacy modus (in Firefox: Ctrl+Shift+P) and you will see the difference. However your IP-address and therefore your location is still transmitted.
  • Even if you have installed privacy protection add-ons in your browser, the combination of your operating system + browser + configuration settings are probably unique.  Therefore you are still identifiable.
  • Panopticlick (from the Electronic Fronteer Foundation) shows you how unique you are: https://panopticlick.eff.org/
  • http://webkay.robinlinus.com/
  • Another website does something similar: https://amiunique.org/fp

You can protect your browser by installing a plugin:

  • FireFox: NoScript
  • Chrome: Safescript
