META AND YANDEX ARE DE-ANONYMIZING ANDROID USERS' WEB BROWSING IDENTIFIERS

Summary from the TLDR newsletter

Meta and Yandex Are embedding tracking code into millions of websites to de-anonymize visitors. The code abuses legitimate Internet protocols, causing browsers to send unique identifiers to native apps installed on a device. It bypasses core security and privacy protections provided by the Android operating system and the browsers that run on it. Currently, the only way to protect against the tracking is to refrain from installing the Facebook, Instagram, or Yandex apps on Android devices.
