You can use your account recovery key to sign in to your Mozilla account to regain access to your data in case you forget your password.

Why does resetting my password reset my data?

Mozilla accounts uses your password to encrypt your Sync data (like bookmarks, passwords and settings) on Mozilla’s servers. If you forget your password and have to reset it, this data will be erased for security – unless you have a recovery key. A unique account recovery key allows you to reset your password without losing synced encrypted data.
