How to Make Yahoo My Home Page on My Computer
A Web browser home page is the page your browser opens to automatically when it is launched. It is also the Web page your browser will go to when you click the Home button. If you find yourself returning to the same page, such as the Yahoo homepage, every day when you first launch your browser, you should make it your home page by changing your browser preferences.
