Rated 5 out of 5 stars

After a couple of years of using a competing (Arch Linux) app I'm returning with a new (Windows) device and downloaded Thunderbird 78.9.0 complete with Lightning calendar integration. Blimey the Thunderbird Project has advanced so much. Exciting for all open source. This latest version of the add-on 'Provider for Google Calendar' has just blown me away. I used to spend hours getting this achieved and I genuinely can't believe how seemless getting it setup was. Outstanding work.

This review is for a previous version of the add-on (78.0.1).
