I find this highly improbable -- the current directory is a vnode
reference saved in the process structure. If it were changing behind
the process's back to some other vnode because of e.g. a refcounting
or locking issue, it's highly unlikely you'd see specifically the
previous-previous directory; you'd get some arbitrary directory or
strange behavior because a regular file got picked up instead.
Likewise for the chdir call retrieving and setting the wrong vnode.
(And if the pointer were getting arbitrarily corrupted, you'd be
It's much more likely that ff8 has a bug. It may not even be using the
current directory as such to manage the state for that file-save
dialog; I noticed with recent seamonkey that setting the cwd before
starting the browser no longer initializes the default file save path
