The following has been tested with Netscape Communicator 4.0 on NT 4 an=
d
4.0b4 on Linux with the same results :

Problem :

  The plaintext password for a machine accessed through FTP is
  displayed by Communicator in some cases :


Method for reproduction

1. start NS Communicator
2. enter a URL of the form =AB ftp://user@host =BB
3. fill in the password in the box that Communicator pops up
4. when the file list is displayed, follow the =AB Parent Directory =BB=
 link
5. click =AB back =BB (seems to be optional in Linux)

The password is now plainly visible in the URL field :
    =AB ftp://user:passwd@host =BB

This is of course a bad thing especially since JavaScript programs can
access the history list.  I haven't had time to experiment with
JavaScript regarding this but I'm certain someone will :)

This has interesting potential.

Netscape has been notified of the problem.
