Remove Yahoo Search from Firefox

Hi Friends,

Yahoo messenger sometimes installs yahoo search in firefox. And when we search something from address bar, it displays yahoo search results. I never want so.. I wanted google back and here it is how to do so..

1. Open about:config in firefox. Just type about:config in address bar.
2. It will ask whether you will be careful or not.. say I'll be careful, I promise!
3. In the search bar search for keyword.url
4. Modify the value to your favorite search engine. I wanted google so I modified the value to
http://www.google.com/search?q=
Now it will be searching google only.. enjoy!!!
