    Other Web Browsers

    Mozilla Firefox (http://www.firefox.com)
    Google Chrome (http://www.google.com/chrome)
    Opera (http://www.opera.com)


    For Network Administrators

    Internet Explorer 9-11 can be configured to accept TLS 1.1 and TLS 1.2 communications network wide by using a group policy. This group policy setting is available on all domains set to 2008 R2 functionality and up.

    Please also check your firewall / proxy server supports TLS 1.1 and TLS 1.2. Just enabling the browser does not fix the firewall. A browser will use the highest TLS it can communicate on and if your Firewall / Proxy Server only supports TLS 1.0 then the browser will try to communicate on TLS 1.0.

    For Microsoft Windows based proxy servers, please make sure you server is running as least Microsoft Windows Server 2008 R2. Any server version below including Microsoft Windows Server 2008 does not support TLS 1.1 or TLS 1.2 communications. You can enable higher TLS communications on the servers by using a free third party program called IIS Crypto. You can find the program at https://www.nartac.com/Products/IISCrypto.
