Safari does not show a warning for normal mixed content websites. However, select site options (such as forms) may trigger a warning. If this is applicable to your operating system and version of Safari, use the steps below for configuration options.

1. Open the Preferences dialog by selecting "Preferences" from the "Safari" menu.





2. Select the "Security" icon near the top of the dialog.
3. Ensure that the "Ask before sending a non-secure form to a secure website" option is unchecked.
