What is a Redirect Tracker?

Firefox being serious about privacy offers features that can block Redirect Trackers making sure you are not tracked and profiled. Available under Enhanced Tracking Protection 2.0, the browser clears such cookies, which cleans the state for the user. Firefox’s ETP 1.0 is used to block trackers from using cookies in a third-party context.  However, it allowed them to use cookies as first-party as it was necessary for the websites. Redirect Trackers took advantage of this flaw. You can call them an intermediate website whose sole job is to make the browser feel like it’s coming from first-party. So when you click on a link that should take you to a retail website, it instead momentarily pass you through a redirect, and then to the retail website. This allowed trackers to be loaded as first-party and were allowed to store cookies. What happens now is the concern. It can access its cookies, which have all information from where you are coming and where you might end up. The result is that using this method, you will be easily tracked across the internet.
