What does the "loginto" choice do? & other questions

Login enters my username, but what is "login to"?

Is automation supposed to work for Firefox? It's not, & it's very cumbersome.

(not that it's working on IE 7 either, but that concerns me less than Firefox.) The boxes show yellow, I have chosen silent entry, but nothing appears. Diablo shows as active on my add-ins.

Is there a secure way of copying a password or list of passwords created on one user account to another? I might need to login to a help site occasionally while trouble-shooting as an admin, but in general I prefer to read online as a user. I also need to copy to another password utility (for thumbdrive.)

How can I import passwords created with another utility into ivault?
(such as created on the fly using thumbdrive).

Is the master password encrypted as I enter it, or can a keylogger access it?
