I have had this trouble a while now, it happens on most games I try to play. The game loads ok, but the game window only opens to a value of 739.702x447.761, regardless of the display size of the game, rendering the majority or games unable to be played due to loosing the bottom and right hand side of the game screen, often where controls for the game are placed. Sometimes a game will have the right click option to "view all" in the zoom menu, but when this is clicked it re-sizes the click field layer of the game to the game window size, but not the graphical layers.
How can I fix this? Is this a problem with Firefox or the website itself, as some games (i.e. Clicker Heroes and BloonsTD 5) resize the game window to reveal the full game interface, allowing play.
