Thunderbird is often asking again to log into Gmail and Outlook accounts. A few days ago the accounts I have were "disconnected" and a few days later, randomly some accounts ask me again to log in and allow access to email. I have about 20 emails managed with Thunderbird and after a few versions (about 3-4 months) this problem started to happen. Has anyone else reported something similar? An observation is that I use MozBackup to make complete backups of emails (including login and password) and restore them after formatting the computer.
