There is a free add-on available for Firefox called Password Exporter. Taken right from site:
This extension allows you to export and import your saved passwords and rejected sites between computers. Your passwords will be exported to an XML or CSV file and can be encrypted.
It works super well, too. You install it just like any other add-on. You can then use it to export your password list from the old browser installation and then import it into the new one.
The only catch I found was that where the site SAYS you can access it is not exactly where I found it. The site says “Tools -> Options -> Privacy (or Security) pane -> Import/Export Password button”. After installing this add-on, I did not have any button in that location. Now, I am using a Mac here and it is unknown whether that has something to do with it. Either way, you can still get to the same window by pulling up your add-ons list, highlighting Password Exporter and choosing “Preferences”.
Thanks go out to the add-on’s author, Justin Scott, for this fantastic time saver.

This is a great article on how to move your saved password, but also can be dangerous if you have someone who wants to take your passwords that is why I’d not install it on my system without quickly removing that from my system afterwards. This is what you call a bad IDEA to keep on your system, but it has a good idea for people who need to migrate over to another system.
