Google Chrome 21 Blocking Multimedia Content

(A captioned version of the video is available @

You may experience problems using Google Chrome version 21 with pages on websites that have security certificates installed (sites that have an “https” in the URL rather than just have “http”).  Or, you may hear from students unable to view videos or other content on your Blackboard or Moodle course site for the same reasons.

Google has started blocking content from sites that are “insecure” from being displayed on secure sites.  If you use Internet Explorer, you are probably familiar with the pop-up window that warns that not all of the content on the page is secure and wants you to afirm that you want the content displayed.  Google has taken this a step further by just blocking the content without warning.  This video demonstrates what is happening and how to work around it when you or your students are using Google Chrome.

Please note that content called insecure by Google is not necessarily harmful to your computer.   You have to consider the source of the content.  If the content is something you have embedded in your course then it should not cause a security issue.  So the the process demonstrated in the video should not provide any security risk for users.  However, please be aware of the content you are embedding in your courses.
