This addon is great, it uses true black, unlike the official "dark" theme from Thunderbird, which is more gray. This addon works on one of my computers, but on the other one, it creates a WHITE background instead of black. It also happens with all the other custom themes. I have the latest version of Firefox (91.12.0). Can anyone help me get this extension to work? The default "dark" theme does work properly, but it's grey instead of black, so I don't like it as much as this one. Thanks!
