I can install the add-on and configure it, but it does not copy anything on quit. Neither can I install an 'export' button in the toolbar, there is no such button available when I select 'customize toolbar'.

Esta valoración es de una versión anterior del complemento (0.3.2). 

mozilla has changed the structure. so i have to change the overlay.
with the next version it will work.
