How do I get rid of google search?

As of the last update, my search engine changed to google. I've disabled google search in tools and have yahoo listed as first and duck duck go as 2nd. Still, in the search bar, all I get is google as the search engine. I've tried all the 'fixes' I've found on the web and none have worked. There's not a way to get rid of google in the list Mozilla tools/search gives.
