Stop the Only Secure Content Is Displayed box in Internet Explorer 9 (IE9)

Learn how to set Internet Explorer 9 to automatically show mixed content on web pages.

When you visit a website that contains mixed content (encrypted https, and non-encrypted http) on the same page Internet Explorer 9 it warns you with a message.

What’s the risk of mixed content on a web page?

  1. Open Internet Explorer 9.
  2. Click the Tools icon (the gear) at the top right of Internet Explorer 9 and then select Internet options.
  3. Select the Security tab in the Internet Options window.
  4. Click the Custom level button in the Security level for this zone section.
  5. Scroll down to the miscellaneous section, set Display mixed content to Enable, and then click OK.
  6. Click Yes when the warning box appears.

What’s the risk of allowing mixed content on a web page?

When you allow mixed content to be displayed on a single web page you’re allowing encrypted and non-encrypted content to be displayed.

If a web page is encrypted no one can read any of the data being transfered between your computer and the server. It just looks like random characters that don’t make any sense. Encrypted pages on a website are usually protecting sensitive information like banking information.

If you’re on a secure web page that contains un-secure content, the un-secure content of the page can read and altar the secure content. For example; you’re on a website and you’re about to check out. The web page will most likely be encrypted to protect your banking information. If there is un-secure content (an ad for example) on the web page it could have code in it that is watching and/or stealing your information.

That’s why Internet Explorer shows the warning when you’re viewing a web page with mixed content.

    Great…this works,
    I’m also having trouble with explorer closing tabs for no reason, with a message along the lines of ‘a problem with this page has caused explorer to close and reopen’. Any suggestions?

    To tackle the problem from the other end, where can I find information on what is secure and what is insecure content on the web page in the first place. I’m trying to develop a secure site.
