Rated 5 out of 5 stars

Makes Thunderbird worth using. Now my various email accounts are in one place, and my google calendar is there too. My laptop now pops up mail and calendar notifications from all of these accounts via Thunderbird - couldn't do that from a web browser. And I can still get to all of it via a web browser if I don't have my own laptop handy.

My laptop is starting to be handier than my phone again.

This review is for a previous version of the add-on (68.2.1).
