Enabling mixed content in your browser

Last update: October 11, 2023

Mixed content occurs if the initial request is secure over HTTPS, but HTTPS and HTTP content is loaded to display the web page. HTTPS content is secure. HTTP content is insecure.

Modern browsers might block the display of a page or display warning messages if secure content is mixed with insecure content.

A warning message displays if the Visual Experience Composer (VEC) in Adobe Target tries to open a page containing mixed content. This message informs you how to disable blocking in your browser. Disabling blocking lets you open an HTTP site or a site that has mixed content (HTTPS and HTTP).

Mixed content warning

Previously, when mixed content was not allowed, you could still perform some actions in Step 1 of the three-step guided workflow when creating activities. Target now blocks actions in Step 1. When this message displays, you must enable mixed content before continuing creating the activity.

Your browser’s security settings might block mixed content or insecure (HTTP) content being loaded into a secure (HTTPS) page or frame (such as the VEC). If you don’t want to disable your browser’s security settings, you must have an HTTPS website.

If your website is running on an insecure (HTTP) domain, you are required to allow the VEC to load active mixed content.

IMPORTANT
Allowing mixed content affects the VEC only and not your live website.

For more information, see Mixed Content on the Mozilla Developer Network (MDN) website.

Enabling mixed content in Google Chrome

If you’re visiting a site via a secure connection, Chrome verifies that the content on the web page has been transmitted safely.

See “Manage warnings about unsafe sites” in Google Chrome Help.

If you are using the VEC with the latest version of Chrome (version 79.0.3945.117 or later), you must update your site settings. Visitors to your site do not need to complete these steps.

  1. Click the lock (caution) icon, then click Site settings.

  2. Scroll to Insecure content, then use the drop-down list to change “Block (default)” to “Allow.”

  3. Reload the VEC page.

Enabling mixed content in Mozilla Firefox

By default, Firebox blocks pages that mix secure and insecure content. You should permanently change this setting to use Target. Visitors to your site do not need to complete these steps.

  1. In Firefox, enter about:config in the address bar.

  2. Acknowledge the warning message displayed by Firefox.
