Used to work fine, but since update I can not use and am locked out of the sites I used it for..

I have no idea which update, I had not used my laptop for a while. All I know is when I tried to use this it says there are no sites configured. I am unable to access the sites I used it for. When I attempted to roll back to a previous version it removed the add-on completely from my browser. I am using Firefox 65.0 atm.

После ввода пароля на все действия, ввести код не успеваю. Пришлось откатиться на старую версию. Экспорт ключей со старой версией не работает. Не надо менять, то что работает.
