They've changed the behaviour of that in the address bar now. Perhaps I have done something wrong, but it appears that what you type in the address bar searches by the search bar's choice. So if I have Wikipedia selected, it searches on Wikipedia from the address bar. This behaviour was initially very confusing. At first I thought I had done something strange to my Firefox (on Linux), but then I noticed both on my workstation (Windows) at work, and on my laptop (Linux and Windows). I hope someone else can confirm this.
