Location data: For security purposes, we store the IP addresses used to access your Firefox Account in order to approximate your city and country. We use this data to 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 Firefox Accounts website, dashboards and menu preferences, what products and services you use in connection with your Firefox Account, and your interactions with our emails and SMS messages. We use this to understand your use of our products and services and to send you more useful Firefox Account Tips and in-product messages.
Technical data: To display which devices are synced to your Firefox 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 Firefox Account to log into other websites or services (such as AMO or Pocket), we receive the timestamp of those log-ins.

Synced data: If you enable Sync, Mozilla receives the information that you sync across devices in encrypted form. This may include Firefox tabs, add-ons, passwords, payment autofill information, bookmarks, history, and preferences. Deleting your Firefox Account will delete related Firefox Sync content. You can also read the documentation.
Technical and Interaction data: If you enable sync, Firefox will periodically send basic information using Telemetry about the most recent attempt to sync your data, such as when it took place, whether it succeeded or failed, and what type of device is attempting to sync. You can also read the documentation.
Learn more, including how to enable or disable sync.
Connection data: If you allow a website to send you notifications, Firefox connects with Mozilla and uses your IP address to relay the message. Mozilla cannot access the content of messages.
Interaction data: We receive aggregate data such as the number of Firefox subscriptions and unsubscriptions to website notifications, number of messages sent, timestamps, and senders (which may include specific website providers).
You can install Add-ons from addons.mozilla.org (“AMO”) or from the Firefox Add-ons Manager, which is accessible from the Firefox menu button in the toolbar.
Search queries: Search queries in the Add-on Manager are sent to Mozilla to provide you with suggested Add-ons.
Interaction data: We receive aggregate data about visits to the AMO website and the Add-ons Manager in Firefox, as well as interactions with content on those pages. Read about data practices on Mozilla websites.
Technical data for updates: Firefox periodically connects with Mozilla to install updates to Add-ons. Your installed Add-ons, Firefox version, language, and device operating system are used to apply the correct updates.
