I think the behavior you propose would be reasonable, but I don't really see
any reason to consider the current firefox behavior a bug. In contrast, I
*do* think it's a bug that wireless passwords have to be decrypted with a
user password by default: I consider the random set of WEP keys that I've
stored in my laptop to be quite a bit /less/ sensitive than most of the
other stuff in my homedir, and I would hate to see this gratuitous use of
encryption wind up giving an attacker some known plaintext that helped in
cracking my GNOME keyring...
(Also buggy: network-manager for second-guessing permissions on files in
/etc/NetworkManager/system-connections, to the point that it *won't use*
profiles that are world-readable! Bug report filed, but still outstanding
Let's please not presume that making users use more passwords default is
going to make things more secure. When the encryption passwordis *expected*
to match the login password in the common case, the attack scenarios that
the added encryption protect against appear to be rather narrow, and IMHO
definitely don't justify a degraded user experience ("password fatigue").
Steve Langasek Give me a lever long enough and a Free OS
Debian Developer to set it on, and I can move the world.
