Google Chrome verifies that the website content you view is transmitted securely. If you visit a page in your Canvas course that is linked to insecure content, Chrome will display a shield icon in the browser address bar.
You can choose to override the security restriction and display the content anyway by clicking the shield icon and then clicking the “Load unsafe script” button.
By default, Mozilla Firefox prevents insecure content from running or displaying right away. This means it will only show secure content unless you change the default security settings.
If you are expecting to see media content on a page but only see a blank space, take the following steps to allow insecure items to run or be displayed.
