CloseReview for Thunderbird Conversations by Skribbles32
Rated 4 out of 5 stars
Functionality is amazing, much needed feature for Thunderbird; just one problem. This add-on is incompatible with dark mode add-ons, so I suggest a dark mode toggle is added to it.
This review is for a previous version of the add-on (4.2.1).To create your own collections, you must have a Mozilla Add-ons account.
