when opening a new tab how can i get the Google search engine 

 

1. In the Location bar, type about:config and press Enter.
   
   • The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
2. Type browser.newtab.url in the search box.
3. Double-click the browser.newtab.url preference and change the url from about:newtab to about:blank. Alternately, you can change it to about:home for the Firefox Google home page, or type in your preferred home page, example Google.com.
4. Click OK and close the about:config tab.
