changing search engines in firefox?

[Cameryn]

I wanna know how i can change the google search engine in firefox, the instructions said to go to about:config and type "keyword.URL" but when i type it in it yields no results, why?
it's like there's not keyword.URL?

Here's a much easier way. On the search bar in Firefox, find the icon on the left side of the search bar. My default search engine is google so it's a g. Click on that. You'll have a dropdown menu and can pick a new search engine.

On the top right search bar you will find "g" dropdown button. There you can select which one you want.
