plain and simple.. 1 problem now after today's update Autoplay option dont recognize youtube as Video/Audio website.. so if i visite website (it wont show Autoplay icon in address bar) and i click on any video (it still wont show Autoplay icon in address bar) it will open up this video and start playing it... but if i refresh that page with that video i clicked on... then firefox suddenly recognize it as a Video/Audio website and show you an icon and not gonna Autoplay it.. all other websites working just fine as before.

2 problem now after today's update when you click on Address bar it only show top websites.. no History no Bookmarks even tho they are marked in settings.. if you turn off option to show Top sites then it will show you nothing at all in there..
