if it has "disabled" under available by default, it means you do have support for it, buts its forced disabled. if you have no disabled at all, then its enabled.
you can force enable it via
and if you want to know if you have webrender enabled:
Code:
about:support X11_EGL = available by default
you can force enable it via
Code:
about:config gfx.x11-egl.force-enabled
Code:
about:support Compositing = WebRender
