Importing and Exporting Firefox passwords can be useful if you use Firefox on more than one computer, e.g. a laptop and a desktop PC, or want to migrate to another browser or password manager.
I guess we all found ourselves in a situation where we were working on a secondary computer trying to remember the password of a website that we wanted to visit.
Update: Please note that you can use Firefox Sync to synchronize password and account credentials across Firefox versions. Another option that you have is the use of an online password manager such as LastPass, which stores the information online for you. All you need to do here is to install the LastPass extension and connect it to your account to access all credentials and other information.
Firefox supports password imports natively but there is no native option to export passwords stored by the browser.
To import passwords at any time after installation (you are prompted during installation to import data from other browsers):
While Firefox does not support the exporting of saved passwords, users on Windows may use the free software Password Fox to extract the saved passwords and export the data to different formats.
Note: Password Exporter is not compatible with Firefox 57 or newer. There is no extension available that you can use to export passwords locally. You could install a cloud-powered password manager such as LastPass, however for that.
Firefox Password Exporter exports all passwords to an XML or CSV file with the option to encrypt the file to increase security (The file can still be imported to Firefox where all passwords are visible).
The very same file can then be used on another computer to import the passwords into Firefox's default password manager. All websites saved this way can be accessed without having to remember the password.
I would like to remind everyone again to set a master password in Firefox if other users have access to the computer. If you do not have a master password everyone with access may export the password list from your account or look up the password directly in the web browser.
If a master password is set it will ask for that password before starting the password export. The extension can be accessed by clicking on the button Import / Export Passwords under Options > Security, or by opening the add-ons manager and selecting options there.
Besides offering to export and import passwords, the extension can be used to export and import the list of disabled hosts. These hosts will never save your password due to policies.
The extension can be useful if you do not want to use Firefox Sync or an online password manager to synchronize account credentials. If you want to be in full control, you may use the Password Exporter extension for that instead as it does not require an Internet or network connection to work properly.
