Browser Security Settings

G&C Mutual Bank understand that some of our members may be experiencing issues connecting to Online Banking. This is because your browser may have the old security settings. It is crucial to optimise your browser security while using Internet securely and privately. Failing to correctly set up your browser's security features can put you at a higher risk of malware infections and malicious attacks.

We have recently upgraded our Online Banking security protocol TLS 1.0, which helps provide stronger ciphers and encryption methods.

Please check your browser settings following the simple steps which can greatly increase the security of your web browser:

Internet Explorer

    • Launch “Internet Explorer”.
    • Go to “Tools” > “Internet Options”, and click on “Advanced” tab. Internet Explorer

















    • Scroll down the list to uncheck “Use SSL 3.0” and check “Use TLS 1.0”.
    • Click on “OK” to save the settings.

    Note: If you have an older version of Windows, such as Windows XP, make sure it is at least patched with SP3 to be able to access sites with SSLv3 disabled.

    Mozilla Firefox

    You can upgrade to Firefox version 34 (or above) which disables SSL3 by default, or alternatively, you may change the configuration of your browser as follows:

    • Launch “Mozilla Firefox”.
    • Type “about:config” in the Location Bar (also known as address bar) and press Enter.
      Mozilla Firefox1








    • If you see the following prompt, click “I’ll be careful, I promise!”.
      Mozilla Firefox2









    • Search for “security.tls.version.min”, double-click it.
      Mozilla Firefox3









    • Change the value to “1” and click “OK” to save changes. This setting will make TLS 1.0 the minimum required protocol version.
