• Stronger site security: We now enforce Certificate Transparency. Sites must prove their certificates were publicly logged before we trust them. This applies to certificates issued by CAs in Mozilla’s Root Program.

• Smarter, faster protection: Firefox now uses CRLite to check certificate revocation on your device. Pages load faster with less data shared and stronger protection against bad certificates.

• Future-ready encryption: Added support for ML-KEM (mlkem768x25519) in TLS 1.3 and HTTP/3, a next-generation approach built to defend against future quantum attacks.

• Lighter translations: Local translation models are compressed with Zstandard, reducing download sizes and storage use.

• Better translation flow: Improved results when translating between languages that read in different directions.

• Smoother, more efficient browsing: Firefox now uses a modern Rust-based networking stack for QUIC and HTTP/3, bringing faster, more reliable connections and improved overall performance on Android.
