The latest versions of Google Chrome come with WebGL enabled by default.
To see what version of browser you're using, click the three dots menu at the top right of the browser and click Help. You can find information about your browser version in About Google Chrome. If there is a more recent version, you should update to it.
If this didn't solve the problem, try following these steps:
1. Go to system settings by entering chrome://settings/system into the address bar and pressing Enter.
2. Enable Use hardware acceleration when available.
3. Click the Relaunch button that appears to apply the settings.
You can also open system settings by clicking the three dots menu at the top right of the browser, going to Settings and selecting System.
