think the new option is actually gfx.webrender.all set to true, at least in nightly. edit: just tested http://output.jsbin.com/surane/quiet http://output.jsbin.com/surane/quiet in 61, doesn't seem to be enabled, going to try 62. Pretty sure they would have announced if it had been in 61, it's a huge addition, and it's probably coming in 62 when it's stable. edit2: neither is it enabled in 62 (beta), also tried with the gfx.webrender.enabled option set to true just in case.
