What every Browser knows about you

Today, as developers, we have many great features built into the browser. On the darker side, many of the features are affecting privacy and security of the user, as a site can read most of the information available even without user noticing anything. A demonstration shows what information a site can get about you without your confirmation. An eye-opener to re-think browser UIs and how much responsibility we, as developers, have to do the right thing. Be it educating the product owners or your own product where you voluntarily display a dialog to give a choice and notice about sending such data to your servers, we should embrace ethics. As a user, I tried to access the demo with a default Chrome setting (revealing horribly much sensitive data) and Firefox with Strict Tracking Protection, uBlock Origin, Disconnect and 3rd party cookies disabled. Despite all blockers, the latter reveals ‘only’ the data about my browser, its active plugins, my hardware and my local and public IP address.
