Risky Bulletin: New fingerprinting technique can track Tor users

Researchers at Fingerprint discovered a vulnerability in Firefox's IndexedDB API that enables tracking of users across browsing sessions, including in private browsing mode and across separate Tor sessions. The flaw allows threat actors to fingerprint and follow users despite privacy protections. Mozilla and Tor Browser users are being advised to apply the latest security patches to address the issue.

Why it matters: This vulnerability bypasses privacy modes in Firefox and Tor, directly compromising tracking protection; patching is critical for users relying on these browsers for anonymity.
