For the second time in the past month, I'm getting a mysterious message every time I open Thunderbird. I'm getting the following message: "Warning: Potential Security Risk Ahead Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details." In addition, I'm unable to send or receive anything to my gmail addresses. On the other hand, my earthlink addresses are working fine. The last time this happened, eighteen days ago, the problem mysteriously disappeared ten minutes later. No such luck this time; it's now been about twenty minutes and no sign that the problem is going away. Help, help, help!!!
