Hello, If there is an embedded video on a webpage, on my 21" iMac on Yosemite, if I resize the browsers window (the browser's window does not fill an entire screen) and click to maximize the player, the player maximizes to fill the webpage. On my 5K iMac, when I do the same, it goes into the full screen mode. In other words, it resizes the browsers window and fills an entire screen. Is there a way to make it behave like it does on the 21" iMac? Thank you.
