I am unable to log onto google/gmail from my laptop. Connection was interrupted. The site could be temporarily unavailable (NOT) Check your computer's network connection. If your computer is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. Please tell me specifically what to do to allow connection from laptop. It works on my ipad and my phone.
