Firefox introduced a feature in Firefox version 80 to let you import login information from a .csv (comma separated values) file.

This feature is currently disabled by default, due to performance issues.

You can also import other data, such as browsing history and saved passwords, from another browser. See Import data from another browser.

Note: Firefox does not save or sync login data from another browser or file unless you choose to import it. This data is stored locally in a readable form on your computer by the other browser.

Import file format

The .csv file to be imported should follow this structure: "url","username","password","httpRealm","formActionOrigin","guid","timeCreated","timeLastUsed","timePasswordChanged"

This should be the default format when you export login data from another browser or from a login export from Firefox.
