[已解決] Firefox 進不了Yahoo首頁??

用火狐上yahoo首頁時
出現:

Sorry, the page you requested was not found.

Please check the URL for proper spelling and capitalization. If you're having trouble locating a destination on Yahoo!, try visiting the Yahoo! home page or look through a list of Yahoo!'s online services. Also, you may find what you're looking for if you try searching below.

但是非首頁卻可以正常連上

IE測過是可以的

為什麼呢??
