First of all, if someone can access your registry files via a
javascript, you have worse problems to deal with.

The storing of the mail password in the registry was mentioned in a post
of mine that can be found at:
http://geek-girl.com/bugtraq/1998_4/0344.html

The password is *still* in the registry after you close netscape,
keeping netscape open is not required.  If they could access your
registry files to begin with, why not save the trouble of digging it out
and just snag prefs.js / preferences.js?

Anyways, my 2 cents..
