Browser does not fill screen on startup

Hello All,

My browser does not seem to want to fill the screen on startup.

I do not want it to go into "full screen" mode, just to fill the whole screen so I do not have to drag the edges every time. The browser does not seem to remember that it was expanded to fill the whole screen when it closed down.

Does anyone know how to fix this?

Screenshot attached.

Regards, Harrison
