I am setting up thunderbird on a new computer running Ubuntu 23.04. I can successfully connect to my gmail account in thunderbird but I cannot add a comcast gmail account. I get an error message "Could not get OAuth2 details for hostname=imap.comcast.net" I am using the correct username and password. I can connect to the comcast email account on this same computer through my web browser. I would like to be able to continue to use thunderbird for all my email accounts. Can anybody tell me what to look at to resolve this problem?
