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.
1. Firefox Browser
- In Firefox, go to the (URL) address bar and type in "about:config" and press the Enter button on keyboard
- Inside the "about:config" window screen, click on the 'I'll be careful, I promise!' button
2. Firefox - changing the mix media settings
- After the Clicking I'll be careful, I promise!, a list will appear and in the Search box, type in mixed to bring up search results.
- Locate and click on the "security.mixed_content.block_active_content" line.
- To set "security.mixed_content.block_active_content" to false by right clicking on the line and selecting the Toggle option.
- Please continue to log into Blackboard, all the mixed media (HTTPS and HTTP) content will be viewable
3. Google Chrome Browser (2 possible screens)
- When a website page has insecure content, the following shield icon will appear in the address bar and click on the shield icon to ope the menu options.
- At this point, there could be 2 different messages: "Load Anyway" or "Load unsafe script". Click on either 'Load Anyway' or 'Load unsafe script' links to successfully load the video or other media content.
- Click on the Done button to exit menu.
NOTE: The URL in the address bar will show a line though HTTPS:// to indicate that the page is not fully secure, but the webpage will load the content.
4. Internet Explorer Browser
- Open Internet Options and click on the Security tab
- Click on the Custom level...button
- In the new window, scroll down to the Miscellaneous area, and under the Display mixed content option, click on the enable option to display mixed content.
- When finished, click on the OK button
- You will need to restart IE to completely enable the new settings. Now, nonsecure content (http://) used inside Blackboard courses will always be displayed on your screen.
5. Safari Browser
Safari browser has different security settings, the embedded content should load without any issues.
- If the embedded video loads slowly then stops or freezes, please click on the Browser's Refresh or Reload the browser webpage/screen.
- If the embedded video loads slowly then stops or freezes, please click on the Blackboard Course's Refresh or Reload inside Blackboard webpage/screen.
- Refreshing the webpage/screen, will make the embedded video reload and successfully load/play.
