Firefox dev unable to display https://www.networkwestmidlands.com/
When visiting the above site in the latest version of Firefox Developer the page fails to render. However, when I view the page in Firefox (regular non-developer version) there are warnings regarding the site using an unsupported version of TLS. Here is the warning:
This site uses a deprecated version of TLS that will be disabled in March 2020. Please upgrade to TLS 1.2 or 1.3.
Will Firefox in the future drop support for TLS 1.1 and lower?
