Why do some pages open in a new browser window?

Browser restrictions prevent unsecure content (served over http) from being embedded within a secure page (served over https). Since many hosted learning management system (LMS) instances are served over https, any external sites displayed in a learning path cannot be directly embedded in the path, and are served in a new window.

To minimize the number of browser windows that open, any external links should be added as https links whenever possible.
