Running Firefox, most webpages I access don't open properly on a 27-inch screen. They don't size properly, for example nytimes.com only opening 9" horizontally, with 6-plus inches of white space left and right. On Google Chrome, which I no longer want to use, pages open full size, full screen, sized appropriately for a large screen. I realize I can use "Command +" to increase page size, but would need to do that each time I reopen the browser or a new page. Can this issue be resolved so that the pages default to appropriate size. Any help greatly appreciated.
