A suggestion: Don't put anything on your desktop. Your computer will run smoother if you keep your desktop completely clean (reason: everything in the Desktop folder has to be placed visually in a specific spot on the display, which means the computer has to track where that spot is, and it uses RAM, as well as CPU cycles, though less significantly, which will bog down the computer). Any browsers or other programs that place items automatically on the desktop, change their settings to use the Downloads folder or some other location on the computer. That way you can just put that in the Dock and have quick access to it.
