Settings not visible/readable in dark mode

[yokuha]

This is TB 115 on macOS – cannot configure as I cannot read settings and info.

This is true for every addon, not only this one. It's a problem of Thunderbird itself

Also, in settings you can force Thunderbird to have white background and dark text and then it will be visible again, configure addon, and remove enforcement.

Settings->General->Fonts and colors -> Click colors
change background to white and text to black,
in the bottom there is override section, select "always" from the menu
accept settings
