The website may try to fallback to TLS 1.0 in a way that is no longer allowed in current releases or may be using a deprecated cipher suite.

You can open the about:config page via the location/address bar and use its search bar to locate this pref:

  • security.tls.insecure_fallback_hosts

You can double-click the line to modify the pref and add the full domain to this pref. If there are already websites (domains) in this list then add a comma and the new domain (no spaces). You should only see domains separated by a comma in the value column.

Maybe this works but it is such an awkward and messy "solution" that it doesn't really qualify.

The real issue here is that FireFox developers have become arrogant and ceased to take note of what users do and need as opposed to their latest fancy theories.

I mostly prefer to use FireFox but if developments continue as at present - lots of unnecessary eye-candy and visual changes but no improvements in the fundamentals such as proper support for multi-processing - then Chrome is what I will have to use.

The add-on works as expected.

Thank you for your help.
