Follow the instructions below if you are receiving the "You need a browser that supports WebGL" error message when attempting to load your Shadow Health DCE assignments.
**If you do not feel confortable changing these settings, please contact support and we will be happy to assist.**
The first thing to check in Firefox is the status of the graphics driver. In the address bar, please type "about:support" (without the quotes) and press enter. Scroll down to the "Graphics" section.
In the WebGL 1 Driver Renderer section, you will likely see a message about the driver version being blocked or blacklisted. This means that the Firefox Crash Guard feature has determined that the graphics driver installed may not be stable and has automatically disabled it.
In the address bar, type "about:config" (without quotes) and press enter. On this page, click the blue "I accept the risk!" button. You will see a page that looks like the screenshot below.
Use the search box at the top of the list to find the settings listed below.
- webgl.force-enabled - set from false to true
- layers.acceleration.force-enabled - set from false to true
- gfx.direct2d.force-enabled (will only appear on Windows 7) - set from false to true
You can change the value of these items by double-clicking them.
After changing these settings, please close Firefox completely and then re-open it. Navigate back to about:support and find the Graphics section again. Now, it should no longer mention blocked or blacklisting the graphics driver for WebGL 1 Driver Renderer.
You should now be able to work on your assignment without receiving the WebGL error message.
**Please note that if you are on a work computer, your company's IT department may have policies in place that prevents these changes from resolving the issue.**
