ups, sorry @OSUblake ... the rgba was a test The original was in rgb, just forgot to delete the 'a' when I reverted tp rgb values. And yes, backgroundColor works fine. Thank you

Hi, As the title says, just before starting the tween the background colour flashes to white. Only on Firefox. I've tried to '.set' and also '.fromTo' to 'force' the starting colour of the background but no avail. Browser: Firefox 55.0.3 (64-bit) Os: OsX 10.11.6 Device: MacBook Pro (Retina, 13-inch, Early 2015) Thank you
