Have always like Noia. Description states a Black scheme option. How to install? Only see blue and gray options in Thunderbird. Thanks!!
This review is for a previous version of the add-on (2.1.3.1-signed).Thanks.
You cannot access to the black theme for Thunderbird. I have worked on it but there is still a lot of bugs. So this is the reason why this option is hidden.
To create your own collections, you must have a Mozilla Add-ons account.
