Thay đổi Search Engine mặc định trên Address Bar của Firefox và Chrome


 When Firefox performs a search from the Address Bar, it queries the search engine string you have setup within Firefox. If it’s using Yahoo, you can switch to Google. Don’t like Google? Use DuckDuckGo. Here’s how to switch which search engine Firefox searches when you use the address bar to search.

1. In Firefox type about:config in the address bar and press ENTER.

2. Locate and double-click the entry for keyword.URL

3. Set the value based on which search provider you would like to use for your address bar searches. Here are a few search strings you can use.

  5. In the Search Engines dialog that appears, select the search engine that you’d like to use from the list.
  6. Click the Make Default button that appears in the row.
