You are sooo right, Myrillya. I am happy you notified me. I am in the process of "trying" to update my themes because of this change someone decided was a good idea. I have changed several but just a fraction of my 20,000 themes. I have submitted a"fix" and it has been approved. It is at: https://addons.mozilla.org/en-US/firefox/addon/aqua-floral/

I posted on my blog yesterday: https://madonnaspersonas.blogspot.com/ for anyone to notify me if they have a specific theme they want changed. If this does not work for you, please let me know!
