[Windows:] Options are unreadable (black-on-black)

Border Colours 2021.4.1 Thunderbird 78.14 x64 Windows 10 Pro - 21H1 (2009: 19043)

When I set Thunderbird's theme to its default theme or to its inbuilt light theme or to its inbuilt dark theme, I see this:

I have not tried the addOn on an other operating system.

Hello there, that's not a useful options page to see! 🤦

Could you check if you have a color override in place in your Thunderbird configuration? See this comment

Right. Understood. Fixed. Thanks.
