Prevents adding new users

This is not a question, just a report. After installing this plug-in, I could not add any new users. Every time I would try to add a new user, I would get a “Passwords don’t match” error, even though on the Add New User screen, there is only one field for entering a password. Also, the Show/Hide button for that one password field would not work. After disabling this plug-in, the Show/Hide button began working again, and I was able to add new users.
