 Opening `about:support` on Windows results in the following output in the
 browser console:
 {{{
 Error: WebGL warning: Unable to restrict WebGL limits to minimums.
 Troubleshoot.jsm:525:18
 Error: WebGL warning: Failed to create WebGL context: WebGL creation
 failed:
 * Troubleshoot.jsm:525:18
 }}}
 The suggestion is that ANGLE is broken. (Reported in our blog:
