Review for Dark Night Arcturus X by HackerKitty
Rated 5 out of 5 stars
I have been using Monterail theme for some years. Now it is no longer compatible with a newer version of Thunderbird. I tested several alternatives and found this theme quite similar to Montrail.
This review is for a previous version of the add-on (3.0).To create your own collections, you must have a Mozilla Add-ons account.
