I don't understand when it is necessary to add "http://" and when is it necessary to add "www." to the web address typed in the address bar? What does Firefox automatically fill in? Is there a way to configure what Firefox will autofill in the url?

When you request an incomplete URL from a server, it usually sends back a redirect to the correct address. Same if you request an insecure (HTTP) page on a server that wants you to use a secure (HTTPS) connection. Over time, these little delays add up, so if you are setting up a bookmark, your home page, etc., go ahead and use the full URL so you can avoid the extra step.

The www.prefix is part of the domain of a website and if the domain without this prefix doesn't exist (a DNS look up fails) then Firefox will automatically try another look up with the www. prefix.
The http:// prefix is the default protocol and uses port 80 to connect to the server.
