By far the most useful feature of Firefox was being able to type in a general term for a web site and being taken straight to that web site. Say I wanted the BBC webiste I simply typed "BBC" into the address bar and hit enter and it would take me straight to "www.BBC.co.uk". Now, with version 4.0, I get the highly irritating AVG search powered by google and I simply can't get rid of it. I don't have AVG installed, I've disabled all add-ons and started Firefox in Safe mode and its still doing it. Please tell me how I can get back the best feature Firefox had over its competition?
