If you're visiting a site by entering the address (as opposed to using search or a bang command on DuckDuckGo or using a bookmark/history entry), then you'd also appreciate the following shortcuts:

Ctrl+Enter (Cmd+Enter on Mac) for "www." prefix and ".com" suffix on the domain. Eg: type "google" <Ctrl+Enter> (or Cmd+Enter) to go to www.google.com

Shift+Enter for "www." prefix and ".net" suffix on the domain. Eg: type "jsfiddle" <Shift+Enter> to go to www.jsfiddle.net

Ctrl+Shift+Enter (Cmd+Shift+Enter on Mac) for "www." prefix and ".org" suffix on the domain. Eg: type "wikipedia" <Ctrl+Shift+Enter> (or Cmd+Shift+Enter) to go to www.wikipedia.org

In my knowledge, the www.<domain>.com autofill with Ctrl+Enter was pioneered by Internet Explorer, but Firefox is the only browser that took it to the next level as a built-in feature.
