Open research, stronger privacy: Making Firefox users harder to fingerprint

Mozilla Security Blog feed covering Firefox privacy and security initiatives, Web PKI policy updates, release-signing key changes, responses to certificate-key compromise, and prior in-the-wild exploit remediation. The most significant incident is the compromise of private keys associated with eight eMudhra intermediate certificates, which could enable unauthorized certificate issuance and browser trust abuse; Mozilla responded with protective measures. The feed also references a Firefox exploit exploited in the wild, but provides no CVE identifiers.
