After downloading a custom theme for windows some firefox dark mode features stop working. For example when right clicking on anything the menu is now white instead of black and the minimize and close button changed from red to blue. Not sure if its my firefox theme that isnt supported. I would really like to keep using this windows theme but I would also like firefox to stay in dark mode.
