Mozilla Thunderbird support so many different add-ons and it’s capable of updating them automatically. Using right add-ons you can have very unique features in Thunderbird, like Auto Sync of your address book with your Google Contacts and many more.
My recommended add-ons:
- Zindus: Sync Personal Address Book or another address book with Google. Manage your Gmail contacts from Thunderbird. And vice-versa.
- Lightning: Organize your schedule and life’s important events in a calendar that’s fully integrated with your Thunderbird email. Manage multiple calendars, create your daily to do list, invite friends to events, and subscribe to public calendars. You can configure this add-on to work with your Google Calendar.
