Mozilla plans to implement a new version of the TLS specification in Mozilla browser. TLS 1.3 will go along with Firefox 52, which is scheduled for release in March 2017. Mozilla representative said recently that the company decided to include TLS 1.3 in Firefox 52. The new version of the TLS specification is designed to solve some of the problems with older versions and is more rapid.
TLS 1.3 is enabled by default in the next release of Firefox 52. TLS 1.3 was developed using the existing security.tls.version.max to control the maximum version. TLS 1.3 – a new version of the TLS, the protocol that protects the web.
It removes old and insecure cryptographic primitives, built using modern analytical methods, is always a step ahead in terms of security, to protect more data and faster than TLS 1.2. It also offers a mode 0-RTT, which removes the delay of handshakes.
Announcement of Mozilla came just a month after Cloudflare announced the inclusion of TLS 1.3 for all of its customers. The new version is more secure and faster than older versions.
TLS 1.3 supports the philosophy of “less is more” by removing support for older types of cryptography broken. You cannot turn a potentially vulnerable things, even if you try. List TLS 1.2 features that have been removed from the new version, it is very voluminous, many removed functions used for different attacks.
TLS 1.3 removes all the deprecated features, so this protocol is more resistant to various attacks. As a result, TLS 1.3 is easier to configure for server operations. The protocol can be even faster, resulting in a better experience of viewing sites.
