In the world of security, everything is important. Even a single leakage can lead to a deadly, heinous attack. That’s why security researchers are always in pursuit to develop the perfect system that’s free of vulnerability. Although that’s not achievable, it keeps the trend moving forward. It’s the reason the internet is nearly safe now. In this process, Mozilla is gradually enabling TLS 1.3 in Firefox.

TLS (Transport Layer Security) 1.3 has improved a lot than its predecessor – TLS 1.2. The newer version offers better encryption, faster negotiation with servers and contains new & powerful features like Zero Round Trip Time (0-RTT) and TLS False Start etc. Moreover, it’s even more powerful to prevent various types of attacks by default.

Firefox users, you can easily enjoy TLS 1.3 in your browser right away. Mozilla is pushing the update via system add-ons. The add-on that’s enabling the change is called “TLS 1.3 gradual roll-out 8.0”.

How to check & manually enable TLS 1.3

Firefox users, you’re free to enable TLS 1.3 manually. Of course, it’s nice to have the latest version for better security.

  • Start Firefox.
  • Go to “about:config”.

  • Search for the entry “security.tls.version.max”.

If the value is “4”, then TLS 1.3 is active. If not, it’s not. To manually active TLS 1.3, double-click on it and set the value 4. Then, click “OK”.

Once enabled, enjoy the improvement of life with TLS 1.3.
