D2L Best Practices: Opening Content Outside of the Desire2Learn Content Viewer

When linking to outside websites and to some documents in your files area in Desire2Learn, it is a best practice to have that content open in a new browser tab or window. There are a couple of reasons for this.

  • First, web browsers often block or give warnings when you try to open “mixed content” on a single webpage. (Mixed content blocking or warnings happen when you are on a secure site–one with a secure certificate and an “https” in the URL–and some elements displayed on that page are from a “non-secure” site–or one that does not have an “s” after the “http” in the URL.) Both FireFox and Chrome browsers block this kind of content by default. (See the links below for more information on these browsers.)
  • Second, documents (Word, PowerPoint, and PDF formats) with active hyperlinks in them have the links blocked by the Desire2Learn content viewer.  This post addresses this issue specifically.

The video below shows how to open items in a new browser window to avoid these things from happening.
