Regarding to Google, "Google Chrome is a browser that combines a minimal design with sophisticated technology to make the web faster, safer, and easier". Unfortunately, Google Chrome is using a client_id variable which is unique for every Chrome user, and which can be used to create exact user profiles of a user's actions while using Google Chrome.
Chrome Privacy Protector is a FREE tool that automatically deletes the unique Client ID before each run of Google Chrome.
To protect your privacy and remove the unique ID from your computer, please launch Chrome Privacy Protector, and then close all Google Chrome windows now in case that it is currently launched, and then click the "Remove unique ID now" button to anonymize your Google Chrome.
