Does Firefox have a url autocomplete shortcut, like IE's shift+enter?
Internet Explorer has a handy feature when typing in url's. When you begin typing and the autocomplete drop-down box pops up, you can press shift+enter to automatically finish typing the top entry and go to that site. Does Firefox have that kind of functionality? I haven't been able to find it in preferences or about:config.

Yes, see https://support.mozilla.com/kb/Location+bar+search
It doesn't work anymore in Firefox 7 if there are multiple domains like support.mozilla
