Firefox has long FOUC on master branch #8328

I believe Firefox is, unlike other browsers, not treating CSS as a render-blocking resource, so it will happily start rendering before the CSS loads...at least if there's no script element following them. Moving a script below the CSS links causes FF to stop and wait for the CSS.
@stevesouders have you written about this? I surely got this trick from you.
