When you first installed Mozilla Firefox, you were given the option to add an icon on your desktop to launch the program. If you elected not to select this option or if it has been deleted, you need to use the Windows Start menu to load the application. You can quickly add or restore the Mozilla Firefox icon on your desktop by creating a shortcut to the program.
Click the Windows "Start" button.
Type “Firefox” in the Search box. This will display Mozilla Firefox in the list of search results.
Right-click “Mozilla Firefox.” Click “Send To,” and then click “Desktop (Create Shortcut).” An icon you can use to launch Mozilla Firefox is now located on your desktop.
