For example, my screen is 1920x1200, and my dad's is probably 1920x1080, but pages such as this only use about 3/5 of the width (left to right) of the screen (on 1920x1200). Firefox 4 uses the entire screen size. I'm thinking there must be a way to get Pale Moon 4 to use the entire screen for web-page viewing when the screen is bigger than the default size for the particular page. How do I do this if at all possible? I've done a number of Scroogle searches and haven't been able to find out yet.
Best regards,
Steven.
