Hello! See the screenshot please: so, I downloaded à pay-bill, with Firefox (under ubuntu), in private navigation, and I get the file with a padlock-symbol at the end. What means that? What means that for me (on my computer), what means that for à friend, when I sent him the pdt-file (can he open it?). Nota: I understood that I can choose between "delete downloads when closing the privat window" or not. And I choosed not to delete them (but there appears this padlock-symbol). Thanks for your help!
