This theme Windows XP Modern – Get this Theme for 🦊 Firefox (en-US) doesnt follow the theme from firefox. I have the light theme but the theme now display the dialog boes in black color. Hold Ctrl + Shift + Del to see this when the theme is installed. I tried to contact the author but the email/reddit links are dead. Reporting this add-on as non-working to mozilla didnt do anything. How can i find him or convince mozilla to fix this.?
