Mozilla Firefox 74 released earlier this month dropped against TLS Support for 1.0 and 1.1 to encourage the transition to a safer system, but now parent company Mozila is changing its decision, so quick and decisive that the latest version of Firefox has also started back in support of TLS 1.0 and 1.1, because Mozilla wants to support the fight against the new coronavirus in this way.
The reason is simple: after Firefox updates to version 74, some sites that do not switch to TLS 1.2 or TLS 1.3 for a secure connection will no longer work. Given that many government websites provide the necessary information about a coronavirus outbreak pages still use the old TLS version, it is the right way to get the feature back to normal so that as many people as possible receive accurate information.
“The recovery time for this change has not been determined, which will give users better access to important government sites that share COVID-19 information,” Mozilla explained in the official release note for the latest Firefox version. “
However, this measure is temporary, and Mozilla explains that TLS 1.0 and 1.1 will still disable TLS again at some point in the future, most likely after the coronavirus outbreak.
The latest Firefox beta version has also restored support for the old TLS version. Mozilla will temporarily re-enable TLS 1.0 / 1.1 support in Firefox 74 and 75 Beta. Preference changes are applied remotely to the delivered Firefox 74 release. The changes involve all versions of Firefox, regardless of what computing platform you are using.
