Browsers leak a lot of data about your system and browsing activities. Below is just some of the common information that can be
captured and processed to create a unique id that follows you around the web. Clearing cookies does not wipe the information
and even using a VPN does not prevent this data from leaking.
While some browsers implement limited anti-fingerprinting capabilities, there is enough data still available that trackers are
able to create useful ids. Only using tools that fully deceive the trackers are able to break this powerful capability.
