Mozilla recently launched a new add-on that would tell users which sites or services are tracking them every time they visit a website. Collusion, developed by Jono X and Dethe Elza, is an experimental browser extension for Firefox that provides information to users as it creates an interactive, real-time graph of all tracking and behavioral cookies downloaded by the browser as they browse from one website to another.
Behavioral cookies are ones that record links users have clicked on, contents they viewed as well as queries they made on the site. These information may not seem important to majority of internet users but they do matter a lot to advertisers and companies that offer optimization services online. You’ll be amazed to know that by visiting a website, there are around ten services tracking your activities.
If it matters to you how your data is being used, we do advise you to install the add-on. Then try visiting a website you used to browse. The graph Collusion presents will display clustered circular icons. The site you visited will be the one in the center represented by its favicon and surrounded by services being used in the site like social media networks, and Google services like Google Analytics and Google User Content.
As you try to browse various websites, the clusters of circles will grow bigger and more complicated. Hover your mouse over an icon and Collusion will tell you if it’s connected with other services other websites are using. So the more websites you browse, the bigger the network becomes. We are not sure how these information would matter to you but the number of circles you see, is the number of tracking or behavioral cookies a website uses.
