We all know that cookies help companies to track your behaviour, preferences and interests throughout the internet – but there is much more that your browser tells about you. Fingerprints of your browser.
Those fingerprints are more than just the cookies. Whenever you visit a website you submit information about your device timezone via the HTTP headers. The browser window size you use which can give information what screen resolution and size you use – when JavaScript is activated. The font you use, some information about your hardware configuration etc.
All this combined provides an unique fingerprint of your device that you use on the internet – if you are looking for an anonymous use of the internet, you should make sure this fingerprint is not to unique, but common.
There is a great page to check the uniqueness of your browser. A project by the Electronic Frontier Foundation (EFF).
