Within the last month I began to get error messages whenever I tried to download mail from Comcast servers. It stated that my Comcast email password failed but I was able to log into Comcast using that password. After trying several times I finally deleted the Comcast account in Thunderbird and tried to reinstall it only to get rejected again at the Comcast login screen. I uploaded the screen images to this message. I have not had any issues with access to Gmail Thanks James Hays
