Thunderbird has been working fine. This morning when opening Thunderbird I am asked. "Would you like a new e-mail address. "Gandi.net" At the bottom are two prompts. "Skip this and use my existing e-mail" or "I think I will configure my account later" Prompt #1 asked for e-mail address and password. Prompt #2 sends you back to the beginning. When choosing Prompt #1 it can't find your settings for your e-mail account. There is a control panel Incoming, Outgoing and username. The other prompt is get a new account. It was working fine, and now I cannot access my e-mail. I tried dragging Thunderbird to the trash and reinstalling. Same issue.
