Perfect. Should be built in to Firefox and Thunderbird! Prevents the appearance of lots of password prompts at startup, which is a real problem if you have Google Calendar sync and Google Contacts sync with multiple Google accounts.
Note if you cancel the password prompt that this add-on shows, you get exactly the behaviour you'd get if you didn't have the add-on. No drawbacks.
