- No, it doesn't need any environment variable: https://www.maketecheasier.com/enable-csd-support-firefox-for-linux/ and Firefox 66 will use CSD by default on Linux (https://www.omgubuntu.co.uk/2019/01/firefox-66-csd-by-default)
This content should be clarified.
gfx.webrender.all = true only works on Firefox Nightly (https://mozillagfx.wordpress.com/2019/01/17/webrender-newsletter-36/)
To enable WebRender on Firefox Stable the process is different (https://wiki.mozilla.org/Platform/GFX/Quantum_Render#Testing).
These environment variables have to be created:
echo 'pref("gfx.webrender.program-binary", true);' >>$HOME/.mozilla/firefox/<default-profile>/user.js echo 'pref("gfx.webrender.program-binary-disk", true);' >>$HOME/.mozilla/firefox/<default-profile>//user.js
