How To Backup Your Saved Passwords In Firefox

To install Password Exporter, click on Install Now
follow the instructions, and restart Firefox after the installation has
completed. When Firefox has restarted, you can access Password Exporter
from Tools Options and select the Security Tab.

Look for the Import/Export Passwords button in the Passwords section:

Once saved, you can back it up or import it to another Computer running Firefox with Password Exporter installed.

NOTE
: The “encryption” feature is mainly to prevent casual
users from stumbling upon your passwords. It will not stop someone who
actually wants to see them, as they could just import your file anyway.
Use good judgment when exporting your passwords.
