Allow Mixed Content in Browsers

All new versions of browsers are set to block mixed (secure and insecure) content by default until you manually change the browser settings.  A secured website has https:// (s means secure) verse http:// (no s, therefore not secure).  This is due to the increase browser security settings to block viruses, non-secure websites or other non-trusted content from loading onto the screen.  Newer versions of Chrome, Firefox, and Internet Explorer browsers, will flag or not load secure and insecure content (mixed media-content) inside a secure BB course.

  • If a picture, presentation, audio track, or video is missing inside Blackboard, most likely the problem is the decision to embed HTTP (un-encrypted or unsecure) content into a HTTPS (secure) environment.
  • If you must embed HTTP (unsecure) content, it is suggested to link out to the content by opening in a new window.
  • If you need to embed the HTTP content in a HTTPS page, please have your students (and you) follow these directions below to allow mixed content on Firefox, Chrome, and IE (and Safari).

Please remember that to view HTTP content in a HTTPS environment, every student has to follow the directions, not just the author/instructor.
