Facebook compiles massive amounts of personal data for targeted advertising without granting users the option of objecting, the watchdog said. The regulator also accused Facebook of collecting data on users' browsing activity on third-party websites without their knowledge.
France first sent Facebook a formal notice about its concerns in January 2016 and also held a hearing about the issue in March 2017, before deciding to impose the fine.
France's investigations were carried out alongside probes by regulators in four other member states, including Belgium, Hamburg, Spain and the Netherlands.
Facebook didn't immediately respond to a request for comment.
