Viewing Course Content and Browser Security
Websites that ask for sensitive information, such as usernames and passwords, often use secure connections to transmit content to and from the computer you're using. If you're visiting a site via a secure connection, some browsers such as Mozilla Firefox and Google Chrome will verify that the content on the webpage has been transmitted safely. If it detects certain types of content on the page coming from insecure channels, it can automatically prevent the content from loading and you'll see a shield icon appearing in the address bar. By blocking the content and possible security gaps, some browsers protect your information on the page from falling into the wrong hands.
Parts of the page may not display when browsers blocks the insecure content. You can choose to override the alert for the page by temporarily or indefinitely disabling the protection. The browser you are using will refresh the page and load its content, including any insecure content. The URL in the address bar may show to indicate that the page is not fully secure.
To allow insecure content to be displayed for all secure pages, enter about:config in the address bar and double-click on this preference, to toggle it from true to false: security.mixed_content.block_active_content
You can also use this add-on instead, to toggle the preference:
You may want to do this only for the current session, then reset the preference back to "true" and check back with the site to see whether it's been fixed, since this is a global setting that exposes you on all sites, not just the one you care about.
When trying to view an embedded video using Chrome, the video will not play. For security reasons, Chrome flags the video as unsafe and a shield icon will appear at the end of the address bar.
To fix: Click on the Shield, then click Load Anyway.
