Where does mozilla sync / weave save its passphrase

Question

I've uninstalled the mozilla sync addon and forgot to save my passphrase. Maybe the passphrase is stored somewhere in the config files or the registry so I can recover my bookmarks. Does anyone know where mozilla saves the configuration for its addons?

Answer 1

Open Firefox's Error Console from Tools menu (or Ctrl + Shift + J).

Click on Clear and type in the following code inside the code box:

Components.utils.import("resource://services-sync/service.js"); Weave.Service.passphrase

When you hit Enter, your passphrase will appear. If you change "passphrase" to "password" and hit Enter again, then your password will appear.
