This is the second time my Thunderbird stopped receiving e-mails and both was after I tried to put on a spam blocker. Every time I open my Thunderbird it tries to receive e-mails. I see the line in the lower right working. Then it times out. My inbox screen halts 3/4 the way down not at the last e-mail. That has happened each time this has happened. All the things on line don't work. Reinstalling, Stop Norton, troubleshoot, clear cache. It seams that my password was changed or something like that. My phone, my other computers all still work. The last time it fixed itself I tried to put Mailbird on my computer. When Mailbird asked for info from Thunderbird to work. Thunderbird sent over incorrect log in info. I corrected it and then Mailbird and Thunderbird then worked. There must be a fix that Mozilla can help me with. Thanks.
