Browser Update:

Due to some security vulnerabilities in certain older browser versions, Bank of O'Fallon's Internet Banking can no longer support Internet Explorer version 8 or older. The most current version of Interent Explorer is IE 11. If you are using this version you should experience no issues. Also, the latest versions of Chrome, Firefox and Safari are supported and users should see no difference in their Internet Banking experience.

If you are unsure what browser you are using, click on the "Help" button in the browser toolbar. The current browser information is available there.

Any users that are using IE 9 or 10 will need to follow the instructions below for enabling TLS 1.2, if they have not already done so.

1. On the Internet Explorer Tools menu, click Internet Options.
2. In the Internet Options dialog box, click the Advanced tab.
3. In the Security category towards the bottom, check "Use TLS 1.1" and "Use TLS 1.2"
4. Click OK.
5. Exit and restart Internet Explorer.
