Firefox (at least for me) does the same thing and pushes search results before websites. I have to arrow or tab down 4-5 selections before I get to the first website result in the url/search bar.
Not sure why you were immediately downvoted. This is absolutely correct. Firefox only prioritizes websites over search when what you typed in the omnibar is an exact prefix match for a site.
Take a bookmark for mail.mycompany.com bookmarked as "Email" -- if you type "mai..." it will complete but if you type "emai..." it will search.
