When Mozilla ships Firefox 52, on or around March 7, 2017, the browser will come with the cryptographic protocol TLS 1.3 on by default.
Martin Thomson, a principle engineer at Mozilla broke the news Wednesday in an email to Mozilla Development Platform members.
“TLS 1.3 removes old and unsafe cryptographic primitives, it is built using modern analytic techniques to be safer, it is always forward secure, it encrypts more data, and it is faster than TLS 1.2,” Thomson wrote.
