when i searched for " WebglAllowWindowsNativeGl:false restricts context creation on this system " in google, without quotes, i saw that at certain firefox version it has become disabled. but there is no explanation, why it was disabled. https://support.mozilla.org/en-US/questions/1334668 "WebGL stopped working after the Firefox 88 upgrade" https://www.reddit.com/r/firefox/comments/ky3m4l/accelerated_graphics_stopped_working_after_an/ "Accelerated graphics stopped working after an update ... firefox 84.0.1-2 -> 84.0.2-1" somebody answers that users can enable it from about:config. i am responsible if i manually enable it. i want to know, why it become disabled.
