I am currently using a portable installation of Firefox 3.6.13, set to save passwords for some sites, using the Master Password feature.

Now, I would like to move all my saved passwords to another Firefox portable installation (4.x Beta). How can I do this?

EDIT: If you suggest alternatives, please suggest solutions that implement the concept of Master Password. This has to be requested every time I launch Firefox, before allowing usage of saved passwords.

Have you tried the "Password Exporter" add-on with 4B? – Tog Feb 11 '11 at 8:09

You could sync both instances using the Firefox Sync Addon Here

You can also use Xmarks to synchronise Bookmarks, Passwords, Open tabs, etc.

You can use LastPass to accomplish this.

One notable advantage of LastPass is that you can access your passwords through a Web interface.
