For some reason when I upload a file as a Yahoo mail email attachment either Yahoo Mail or Firefox does not open the directory I last used to upload a file. Instead it seems to have got stuck on some arbitrary directory. This is SO annoying as I generally have multiple files to upload usually from the same directory, which means, now, that each time I have change from that arbitrary directory to the directory I want to upload from. How can I get Yahoo Mail/Firefox to behave as it always has? Which was, that when I uploaded a file as a Yahoo mail email attachment, it opened the directory folder I last used to upload from.
