All the stuff at the top of my screen, print and icons are too small. How do I enlarge the bar on the top of my screen?.

Can you give us a screenshot? Is anything else too small? Other apps?

You can set layout.css.devPixelsPerPx to 1.0 (default is -1) on the about:config page. Adjust its value in 0.1 or 0.05 steps (1.1 or 0.9) until icons or text looks right. Modifying layout.css.devPixelsPerPx affects user interface and web pages (global zoom). You can use an extension to correct the appearance of web pages.

You can look at the Zoom Page WE extension to set a default font-size and page zoom for web pages.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

You might find 1.0 to be smaller than what Firefox was using before. That's because the value Firefox uses when it is set to -1 (the default value) is the Text Size setting in Windows 7. So if you normally have Windows 7 set to a Text Size of 125%, the numeric value to match that in this Firefox preference is 1.25 (150% => 1.5, etc.).
