Firefox tracks you with “privacy preserving” feature
Today, noyb filed a complaint against Mozilla for quietly enabling a supposed “privacy feature” (called Privacy Preserving Attribution) in its Firefox browser. Contrary to its reassuring name, this technology allows Firefox to track user behaviour on websites. In essence, the browser is now controlling the tracking, rather than individual websites. While this might be an improvement compared to even more invasive cookie tracking, the company never asked its users if they wanted to enable it. Instead, Mozilla decided to turn it on by default once people installed a recent software update. This is particularly worrying because Mozilla generally has a reputation for being a privacy-friendly alternative when most other browsers are based on Google’s Chromium.
Firefox follows Google? With a recent Firefox update, Mozilla seems to have taken a leaf out of Google’s playbook: without directly telling its users, the company has secretly enabled a so-called “Privacy Preserving Attribution” (PPA) feature. Similar to Google’s (failed) Privacy Sandbox , this turned the browser into a tracking tool for websites. The idea: instead of placing traditional tracking cookies, websites have to ask Firefox to store information about people’s ad interactions in order to receive the bundled data of multiple users.
