😍 Oh, my.....you made this great grandma cry. I am so pleased you enjoy my work. I know Firefox keeps changing things and I have a hard time keeping up! I am trying to update all my themes now to highlight the open tab. But I don't have the choice of changing the drop down menus...I, too wish Firefox would try to integrate the background colors of the theme....hopefully they may with time. I must have some setting checked because I always use a darker theme because it is easier on my eyes. I just checked and my drop downs are black. You might want to check out some settings in Firefox to make them either dark or light at least. Thank you so much for the wonderful review and comments. Have a great autumn and stay safe!
