What is set in your Firefox configuration in the variable security.tls.version.max? (about:config, then search for security.tls.version.max)
What TLS versions does your server deliver? (# plesk sbin sslmng --show-config)

As both configurations seem to match there is some likelihood that your computer is infected with malware that is redirecting browser requests to a third-party.
