CloseReview for Thunderbird Conversations by elhennig
Rated 3 out of 5 stars
The addon is really valuable but it quit working after an update to the latest version 52.6.0. It does not work together with the Provider for Google Calendar and as that is more important to me I had to disable the Thunderbird Conversations.
This review is for a previous version of the add-on (2.13.4).To create your own collections, you must have a Mozilla Add-ons account.
