Mozilla disables tls 1.0 and 1.1 in Firefox Nightly

Mozilla has disabled tls 1.0 and 1.1 in the Nightly version of its Firefox browser. The intention is that the outdated encryption standards will no longer work from March next year, in the stable version.

Mozilla had previously announced that it would disable tls 1.0 and 1.1 in its browser, and as of now, the test version of Firefox will not accept connections via the outdated standards. Users will then see an error message. The intention was that Firefox Nightly would disable tls 1.0 and 1.1 from October, but that happened a little earlier, Mozilla says.

Few problems are to be expected, as last year already 94 percent of sites were switched to tls 1.2 and 1.3, which continue to support all major browsers. Sites that aren’t over yet should do so soon. Tls stands for transport layer security and is a standard for the encryption of web traffic. The first version of tls dates from about twenty years ago. Besides Mozilla, other browser builders will also stop supporting tls 1.0 and 1.1, including Google, Apple and Microsoft.
