Dear all, Regardless of the theme in Thunderbird I choose, whenever I open a message the background color of the messages is light yellow, what is quite awful and often prevents some message from been read because of the lack of contrast. I can't find a way to change that. Is there a way to change that, for instance by editing the contents of the XPI of the theme I use? What should be the CSS code used for that? thanks a ton for you attention!, best
