CloseReview for Numix Blue by andrybak
Rated 5 out of 5 stars
Despite its name, this is the nicest Dark Grey menu bar theme for Thunderbird 68, where by default the menu bar is very bright.
This review is for a previous version of the add-on (1.2).To create your own collections, you must have a Mozilla Add-ons account.
