Mozilla Firefox will require user intervention to connect to websites using the TLS 1.0 or 1.1 protocol from March 2020 - and plans to eventually block those weak HTTPS connections entirely.
Web servers should really be using TLS 1.2 or 1.3 for their encrypted and secure HTTPS connections.
The PCI Data Security Standard for sites handling credit card transactions has required at least TLS 1.1 since 1 July 2018.
Will this cause problems? According to SSL Pulse, which gives TLS version stats based on the top 150,000 most visited websites, 96.8 per cent support TLS 1.2.
That said, 71.5 per cent also support TLS 1.1 and 61.5 per cent TLS 1.0 so it is possible, but optional, to connect using these older versions.
