Bulk Stored Password Changer per Dmitry Karasik

In our corporate network we are obliged to use common authentication to access many of the company internal web sites. While under Windows that works seamless with its domain-based Kerberos tickets, Linux integration is not that smooth, and Firefox asks for a password each time it interacts with another internal site. Worse, the password is changed each three months, so it is a never stopping process of entering password again and again.

Since the password is the same anyway for all sites, I wrote this addon which asks for the old password, the new password, and replaces one with another in one go.
