如果Firefox無法連結網站，但是其他瀏覽器可以，請按照以下的流程。

更新Firefox後無法連結網頁

If you were able to load websites until you updated Firefox, your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) is likely preventing Firefox from connecting to the Internet. Some Internet security programs can block Internet access even when they are in a "disabled" state.

一版來說， you should remove Firefox from your program's list of trusted or recognized programs, then add it back. For instructions on how to configure some programs, 請參閱 設定防火牆使 Firefox 能夠存取網際網路 。
