What search engine does Firefox use?
Firefox doesn't have its own search engine and it uses google as its search bar.
The address bar makes it easier for you to find what you’re looking for. Enter search terms or a specific web address to get search suggestions, your top sites,bookmarks, history and search engines — all within the same field.
You can also update Firefox or fix performance issues right from the search results. On occasion, you may see a tip from Firefox on how you can save time while searching.

Searching with the default search engine
When you search using the address bar, this will use your default search engine. Simply type your search term in the address bar and press Enter.
To change your default search engine, see Change your default search settings in Firefox.
Access Top Sites from the address bar
Top Sites are a combination of your most recently and frequently visited sites, as well as the sites you’ve pinned. You can access your top sites from the drop-down list that appears when you click the address bar. If you’ve installed Firefox for the first time, it suggests top-ranked sites by default.
