Trying to make the bright white background, less bright. Cannot figure out how to change the brightness or contract...other then to change to a different color background. My eyes are sensitive to the brightness. I am a brand new user. Thank you

You can set font sizes (text/page zoom) and text colors on web pages with the NoSquint extension.

while holding down the "Fn" key, just to the right of the Ctrl key on the left side of the keyboard, tap the down arrow key as low as you like (or the up arrow key as bright as you like) see: http://www.ehow.com/how_4851634_adjust-screen-brightness-laptop.html
