How to get a normal window screen
when i click on to Mozilla Firefox the screen goes black for about 10 seconds, and then when it does come on everything on the screen is enlarged. When i sign off, the screen goes black again to go back to the opening window, with everything there in normal proportions. How do i correct it?
