How to Change the Homepage on a Firefox Browser
As with other Web browsers, the Firefox Web browser gives users the ability to set a homepage for the browser. This homepage will be the website that appears each time that you open the Firefox browser or click the “Home” button that is found at the top of the browser. Firefox comes with a default homepage but you may wish to change the homepage to your favorite search engine, email page or other website.
Open a Firefox browser.
Click the “Tools” menu. Select “Options.” A window will open.
Select the “General” button (“Main” button if you're using Firefox 3.5 or higher) at the top of the window.
Enter the link for the desired homepage in the “home page” text box located inside of the window.
Click the “OK” button positioned at the bottom of the window.
