I love the feature that Firefox searches my history and bookmarks when I start typing in the address bar.
However since recently, Firefox also suggests URLs of the form <host>/ when I start typing parts of a host name, although I neither have visited nor bookmarked that exact URL. This is quite annoying because there are a lot of servers (especially company-internal ones) which don't respond on these URLs. Typically, they require a special port (and I have the right one in my history), but Firefox still tricks me into using the wrong, default port.
So, how can I disable the host completion feature and make Firefox only propose the exact URLs that I have visited or bookmarked?
EDIT to clarify the expected behaviour: When I start typing a host name in the address bar and hit enter, I want Firefox to open the first element of the history/bookmark search results shown below the address bar, and not the URL which consists just of the host name, which is shown in the address bar. Is this possible?

I just found out that the feature I am not quite happy with is the inline auto-complete option of the location bar (which is one of multiple auto-complete options). Apparently, it is not possible to change the behaviour of inline auto-complete so that only full URLs from the history are proposed.
But it already helped me to disable the option (by setting
browser.urlbar.autoFilltofalseon the about:config page). In this way, I still need to press down and enter to select the first matching history entry, but at least I am no longer tricked into trying to open URLs that will show an error page.
