Internet Explorer 8 is the last version of Internet Explorer by Microsoft support that works in Windows XP. Its successor, Internet Explorer 9, works in Windows 7 support and Vista. Internet Explorer will interrupt a download when using HTTP based resources on a secure HTTPS page by displaying a security warning. You might be getting this warning message because the website relies on non-secure images, CSS or JavaScript. You will be prompted whether you want to view only the Web page content that was delivered securely. However, you could easily get rid of that warning pop-up for good.
Steps:
2. Select the "Security" tab. Click on the "Custom Level" button toward the bottom. The Security Settings dialog appears.
3. Scroll down to the "Miscellaneous" section. From the "Display mixed content" option, click the radio button next to "Enable." The security warning box will no longer prompt you.
