Hi, I just got a new machine, moved my profile folder over, and installed the latest Thunderbird 78 before seeing the warnings about waiting. Oh well, done now.

Even if Thunderbird does not seem to require a restart, do it anyway. That minute or two it takes is well spent and might save you a lot of trouble later on. Open the TbSync account manager. In the Tools menu, you now have Synchronization Settings (TbSync) if your restart went properly. If not, go to add-ons and check for compatibility issues.

Synchronizes contacts & groups between Thunderbird and Google Contacts. Imports Facebook friends, contacts you follow on Twitter, and more. Place phone calls directly from Thunderbird's address book. Synchronize calendars, contacts and tasks to Thunderbird via Exchange ActiveSync or CalDAV/CardDAV. Converts telephone. Jun 24, 2020 Mozilla Thunderbird is an opensource email client with fantastic use cases. It got a lot of enticing features such as chat options, RSS feed reader, and newsgroup options. Plus, it offers better security and the provision to manage many email accounts seamlessly. Cannot Delete Messages. Users often find it difficult to delete messages in Thunderbird. Depending on the operating system you use, find the menu option Synchronization Settings (TBSync) Choose Account Actions, Add New Account, Exchange Activesync Choose Office 365. Enter a descriptive name (for example, “Argonne”) and your email address.

At this point, I just want to get my Google Calendar accessible. The settings seemed to move over with the profile, since it can be seen in the Calendar dropdown, but when I double-click the calendar the popup message is 'The provider for this calendar could not be found. This often happens if you have disabled or uninstalled certain addons.'
I tried unpublishing it to start over, but after every Thunderbird restart the greyed out Google Calendar is still there.
So instead I tried uninstalling and then reinstalling the following: ... -calendar/
However, when I then try to create a new calendar, choosing 'On the network' as I'm supposed to, there are only 'iCalendar' and 'CalDAV' options, not 'Google Calendar'. It appears this no longer works with Thunderbird 78. Nor does any other addon I tried. Help!
Any ideas on how to connect to my Google Calendar with Thunderbird 78?

If you want to see the comparison of LibreOffice suite vs. MS Office, see here: Feature Comparison: LibreOffice - Microsoft Office.


This page compares the features of Mozilla Thunderbird 60 (download) and Microsoft Outlook 2019. LibreOffice does not have a PIM⁠ module and therefore users looking for a suitable PIM⁠ software need to seek alternatives for email, calendars, contacts, tasks, and chat features. This comparison table has the objective to assist users in this search. Mozilla Thunderbird is a fully-featured PIM⁠ tool. Like LibreOffice, Thunderbird is a free, open-source, cross-platform program. There are alternatives to Mozilla Thunderbird available, such as Evolution⁠ and Kontact⁠.

Please note that neither the LibreOffice developer team nor the Document Foundation gives any official recommendation for a PIM software replacement for LibreOffice.

This table separates major and minor feature differences and also includes notes on Thunderbird add-ons. The comparison highlights differences and therefore does not display any features which are present in both PIM⁠ programs.

The feature comparison table is work in progress and currently incomplete.
This table is a compilation by users and not an official document by the Document Foundation or by the Mozilla Foundation⁠.
