Firefox Privacy Notice

Mozilla Accounts Privacy Notice

In this Privacy Notice, we explain what data Mozilla collects and shares about you. We also adhere to the practices outlined in the Mozilla Privacy Policy for how we receive, handle and share information we collect when you have a Mozilla account. Additional information may be collected and shared by the different products and services you have access to with your Mozilla account. Read the full documentation or learn more, including how to manage your Mozilla account data or our data practices for websites and email. You can also read the Privacy Notices for our Mozilla account connected services, which are:

Things You Should Know

Registration data. Mozilla receives your email address and a hash of your password when you sign up for a Mozilla account. You can choose to provide your age, as well as to include a display name or profile image. Your email address is sent to our email vendor, Braze, which has its own privacy notice; we use Braze’s services to communicate with you.

Location data. We use the IP address in order to approximate your location for fraud and abuse prevention purposes across our products. We will send you email alerts if we detect suspicious activity, such as account logins from other locations.

Interaction data. We receive data such as your visits to the Mozilla accounts website, dashboards and menu preferences, what products and services you use in connection with your Mozilla account, and your interactions with our emails and SMS messages. We use this to understand your use of our products and services so we can improve them, and to send you more useful Mozilla account tips and in-product messages. Learn more about the Interaction Data we collect in the Glean Dictionary and our Data Documentation.

Technical data. To display which devices are synced to your Mozilla account and for security functionality, we store your device operating system, browser and version, timestamp, locale, and the same information for devices connected to your account. If you use your Mozilla account to log into other websites or services (such as Pocket or Mozilla VPN), we receive the timestamp of those log-ins.

Other Information You Should Know

You can learn more about managing your data and how to enable or disable sync. Also, much of the information that we store about our Mozilla account users is easily accessible by signing in to your account, where you can also update your data sharing settings. To make requests regarding your personal data, please contact us through our Data Subject Access Request Portal.

If you have any other questions regarding personal data or our privacy practices, please contact us at We respond to all requests we receive from individuals wishing to exercise their data protection rights in accordance with applicable data protection laws.
