Firefox location autocomplete without “Down” key (then enter)

Question

Here is the situation :

I type for instance "f" :

Then I should press the "Down" :

And finally press "Enter" to go to the website.

Instead, in Chrome, I have just to type "f" :

Then Enter and it go to the website.

How could I skip the "Down" key step?

(I very often use the location bar this way, and with a netbook it's even annonying)

Add Facebook to bookmarks; right-click the bookmark, click Properties, then enter f to the Keyword box.
