CloseReview for Provider for Google Calendar by Tomas
Rated 3 out of 5 stars
Great add-on, I've been using it for years. Unfortunately, with the new Thunderbird (102+) the synchronization stopped working. Please correct it.
This review is for a previous version of the add-on (102.0.0).To create your own collections, you must have a Mozilla Add-ons account.
