Why can't I change my homepage in Firefox?

Episode 1315 (45:19)

Ed from Lyle, CA

Every time Ed opens up Firefox, it goes to Google. He keeps changing it to another page and it goes back to Google every time he opens it. Leo says it sounds like it's been changed in the settings by an extension or toolbar. Many companies make money by having their extension on your browser. Ed should right click the icon and select Properties. He should look to see what the shortcut is. He should try resetting his browser.
