I have several Google accounts. For each one, the first time I checked my mail, I got a Thunderbird pop up saying "See, edit, share, and permanently delete all the calendars you can access using Google Calendar" and another Thunderbird pop-up saying "See, edit, download, and permanently delete your contacts", followed by two "Mozilla Thunderbird Email was granted access to your Google Account" emails to each account. And for all accounts but one, that was the end of it. But for one account, for some reason, I have to go through the whole authorization process again each time I start Thunderbird. I tried deleting the account, and Thunderbird still made me go through the whole authorization process -- for an account that no longer existed! I re-created the account. No change. Any idea what the problem is? It started after a Thunderbird update.
