This article explains how to retain login information for users who experience issues when upgrading to Firefox 73 or above from older versions of Firefox.

Some users have experienced issues with the [[Password Manager - Remember, delete and edit logins and passwords in Firefox|Lockwise Password Manager]] not saving usernames and passwords when updating from an older Firefox version. This is due to a migration from using {filepath key3.db} (in older versions) to {filepath key4.db} (in current versions) where the decryption key is not migrated properly. This article describes how to safely migrate your login data for the latest version of Firefox. {note}'''Note:''' This issue has affected users updating from Firefox versions prior to 73. If you are migrating from a newer version, you may be experiencing a different issue and you should ask for help on the support forum. See [[Get community support]].
