Firefox 23 – Mixed Content Handling

Mozilla recently released Firefox 23 which introduced a new way of handling “mixed content”.  Due to this change, you may experience issues viewing some content that is available in your D2L courses.

What is “mixed content”? Whenever you visit a secure webpage (served over HTTPS), the connection between your computer and the webpage is encrypted to secure your information.  When the secure webpage attempts to load content that is not delivered over an encrypted channel – such as images, audio files, video files, and other media – the browser will detected this as “mixed content” and will not display it on the webpage.

How do I disable “mixed content”? When the browser detects “mixed content”, you will notice a “shield” icon that will be displayed directly to the left of the webpage address.

Simply click on the “shield” icon, click the arrow on the drop-down menu and choose “Disable Protection on This Page”.

The “mixed content” will now be displayed correctly.  Anytime you load the webpage, you will see a “warning” icon.  This simply means that “mixed content” is now being displayed on the page.
