when I start up Firefox on Macbook Pro, Version 10.12.6, Firefox does not cover entire screen; it leaves 1 1/2 inches on right and on the bottom still showing the blue background of the Mac's home page. How do I make Firefox cover the entire screen?

When I enter a Password, I'm offered the choice of Save PW, Never Save PW. If I click on Never Save, the next time I enter this password, I must again click on Never Save.
