Steps to reproduce:

2d canvas animations freezes while playing

For example, FLIF demo page, which uses canvas fallback to display FLIF images

I also making many banners in Animate CC using createJS which plays smooth in chrome and other browswes, but not on firefox, espacially "fluid" 100% width banners.

CPU load OVER 100%! Attached screnshot while playing banner

Actual results:

Rotating firefox logo freezes many times while rotate on http://flif.info/animation.html

Or go to one of my banner page to test http://ab.rfweb.ru/b/2016/08/290816/1/1000x90-2.html

I tested this issue on Mac OS X 10.10 with FF Nightly 51.0a1 and FF 48 release and I can't reproduce it. I used http://flif.info/animation.html and for me the Firefox logo plays smooth.
