There is information on what it is and how to enable it here in the Help Center. The relevant bits on activation are: Turning Hardware Acceleration on in Chrome First, access your settings in Chrome, either by typing chrome://settings in the web address field, or selecting the three dots on the upper right of your browser and selecting Settings. From there, you can access the Hardware Acceleration toggle under the System category. Turning Hardware Acceleration on in Firefox First, access your settings in Firefox, either by typing about:preferences in the web address field, or selecting the three bars on the upper right of your browser and selecting Settings. From there, ensure the Use Recommended Performance Settings checkbox is unchecked in the Performance category, and the Use Hardware Acceleration When Available button is checked. It is a concern that you never got any response at all from the Help Center. Did you not even get the automated "we received your report" email?
