Firefox used to open full screen. Since last update I need to manually maximize the window. I have already changed the properties of the shortcut to Start Maximized (windows 10) Solution please to have Firefox start maximized.

Hi Testah2 I have since found the answer although how it happened is still a mystery. What I did notice is that the program appeared to not be full screen like the edges had been dragged in. So I tried dragging the edges of the program window out as far as I could on all 4 sides. Since then, the program now start in full screen mode. Like I said, I have no idea how it happened in the first place or any relevance to the update. Mystery!
