Disable WebGL in Google Chrome and Firefox (Quick tips)

A recent report by the independent information security consultancy Context reveals that the new graphics engine WebGL, which is enabled by default in Firefox 4 and Google Chrome, opens the browsers to serious attacks, including the remote execution of malicious code.
Based on this report, the US Computer Emergency Readiness Team (US-CERT) advice users to review the report and disable WebGL in their browsers to help mitigate the risks.

For your information, WebGL is a new web technology that brings hardware-accelerated 3D graphics to the browser without installing additional software. It is enabled by default in Firefox 4 and Google Chrome and is included in Safari and Opera.

    The Google Chrome steps are incomplete and I know of no workaround. This only disables WebGL if you launch Chrome from those icons/shortcuts. If you instead launch Chrome by opening a favorite, url shortcut, link within another document (email, pdf, word, etc.), it will launch Chrome from settings in the Windows registry and therefore NOT see the command line flag. It will unfortunately launch with WebGL support.

    No known fix.
