Mozilla re-enables support for the outdated tls 1.0 and TLS 1.1 protocols in Firefox after removing it previously. In this way, the company wants to keep government websites accessible during the corona pandemics that still use the old protocols.
Mozilla will implement the changes the release notes of Firefox 74.0. That version came out a week and a half ago. It was the first version of Mozilla to disable support for tls versions 1.0 and 1.1. Websites that use older protocols than tls 1.2 and 1.3 could no longer be visited in Firefox from that moment on. Users were then presented with an error page with a button to force newer tls versions. That change has since been reversed, says Mozilla. “We are doing that indefinitely to improve the accessibility of government websites that post covid-19 information,” the company writes.
TLS 1.0 and TLS 1.1 have long been obsolete. The protocols are now more than ten years old. Earlier this year, in addition to Mozilla, Apple, Google and Microsoft also decided to phase out the protocol in browsers Safari, Chrome, and Edge. It is not known which government websites currently use TLS 1.0 and 1.1. The protocol is still rarely used. In Firefox would still 1.2 percent use all https connections of the protocols.
