Firefox not opening to full screen

My Firefox browser used to open in full screen but for the last 2-3 months it only opens about 2/3 of the screen. Pressing F11 does not work. It only works if I press the centre icon in the upper right corner of the browser.

This happens every time I open the browser. I have looked on Google but nothing works for me. It used to work fine and I do not know what has happened. Another browser works fine but Firefox does not. Any assistance is greatly appreciated. Kind regards
