Whenever I type something in my address bar (other than a url), Firefox automatically uses Google search to give me results for it. Where can I change this behaviour in Firefox? I'm using Ubuntu 12.04 Gnome classic.
Edit 1: Changing the behaviour as in, making another search engine as the default one.
Edit 2: What I want is: While typing in the address bar, it should use a search engine of my choice to search. However, I want the search engine text box (the text box to the right of the address bar) to use google itself if I type something in there.
