I have linux (mint 18) and Thunderbird 60.2.1 and got it working following this steps: 1. Delete lighning extension 2. Install package: xul-ext-lightning: sudo apt install xul-ext-lightning 3. Open Thunderbird again and calendar should be there. Thunderbird 3 has carried Thunderbird 4 in the cargo bay, seen in Deep Search. The TV-21 contains the most powerful thruster that Brains has built and is capable of reaching a top speed of 15,300 mph, 300 mph faster than Thunderbird 1. However, Thunderbird 3 can reach a top speed of 25,200 mph, thanks to its ion engine, which the TV-21 lacks.

Thunderbird is an email client from Mozilla, the organisation better known for the Firefox web browser which has a great deal to offer. In addition to handling multiple email accounts, the program can also be used to subscribe to RSS feeds and access online newsgroups and a new tabbed interface makes it easy to jump between individual emails or different aspects of the program.
There are new tools available to make it easier to manage a burgeoning inbox Email archival makes it possible to remove messages from your main inbox while retaining them for future reference, and the advanced search facility takes the hard works out of tracking down messages using a keyword filtering and timeline system.
As is the case with Firefox, Thunderbird supports addons can be used to customise and extend the features of the program. Getting started with the email client has been greatly simplified thanks to automatic account setting detection and nice touches such as the appearance of a warning if an email is written which includes the word 'attached' but no attachment is added make Thunderbird a joy to use.
With advanced security, phishing protection and automatic updating, coupled with countless other features which are simply not found in other email clients, Thunderbird is the ideal program to handle your email correspondence and much more.
Verdict:
Evolution rather than revolution is the buzzword for Thunderbird, but all the improvements are welcome, nonetheless.
Thunderbird 3.1 4.6
The team behind the Thunderbird email app has released version 78.4.1. This is a maintenance release with a number of important fixes. Also, there is a new minor feature that changes how Thunderbird works with an Address book entry with multiply email addresses.
Thunderbird 3.1
Thunderbird is my preferred email client of choice. I use this app on every PC and on every operating system I use. It is stable, contains all the features you need, supports add-ons and also comes with a useful RSS reader. I am using Thunderbird for many years and never felt the need to look for an alternative.
Thunderbird 78 doesn't support classic XUL add-ons any more, but includes some of their features natively. E.g. on Windows you can minimize the app to the system tray.
The following changes have been made in versions 78.4.1
