Are you having playback issues due to Digital Rights Management in your free Internet browsers? If you need to enable DRM, the below information should be helpful. I am a Hackintosh user who operates macOS, Ubuntu, and Windows daily and loves watching Amazon Prime Video on Ubuntu so I have seen the issue many times and have safely and successfully corrected it in the past.
Enable DRM in Chrome
To enable DRM in Google Chrome, search for “protected content” under chrome://settings and enable it. By default, it is enabled but an extension may have turned it off for your privacy. For a list of Chrome URLs, see the accompanying page.
Enable DRM in Edge
To enable DRM in Microsoft Edge, search for “protected content” under edge://settings and enable it. By default, it is enabled but an extension may have turned it off for your privacy. For a list of Chrome URLs supported in Edge, see the accompanying page.
Enable DRM in Firefox
The Firefox browser will provide a one-click button for you to enable DRM so you do not have to hunt through all of the settings. To check to see if DRM is enabled, go to Amazon Prime Video and try to play any content. If you close it accidentally or need to adjust it manually, search for “DRM” under the setting page.
Enable DRM in Opera
Getting DRM in Opera to work will depend on if you are running Windows or an alternate Operating System such as Linux. You can, however, search for “protected content” under opera://settings/ and enable it.
