By default, whenever you type anything in address bar and hit enter or press the GO button, Firefox checks whether the entered string is valid address or not. If it’s a valid address Firefox tries to load corresponding site for you. Now, if the entered string is an invalid URL, it will be submitted to Google Search and search results are returned.
What if you want to change the Default search engine? Of course, Google is everybody’s first choice search but having said that it depends on person to person. Or, if you have Google Toolbar (that provides inbuilt google search box) installed then you may want to configure the address bar with some other Search Engine.
