I just got a new computer with Windows 8.1 on it. I downloaded Thunderbird 24.6.0 on it, however, the same thing is happening that was happening on my old computer with Windows XP. When I open an email that appears to have a live link on it, nothing happens when I try to go to the link. I can copy the link and paste it in my browser but cannot get there through Thunderbird. I have also noticed that I don't always get all of my mail. Thank you.
