This case concerns:

Over the last decade, the company tracked millions of users using Android apps to listen on localhost ports, allowing them to link web browsing data to user identities and bypass typical privacy protections without its users’ knowledge or consent. These practices, which impacted millions of users, allowed Meta to bypass common privacy safeguards like cookie clearing, Incognito Mode, and Android's app permission system, at the expense of Quebec residents’ contractual, statutory, and human rights.
