Firefox Autofill

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. Note: The credit card autofill feature is available starting in Firefox version 81 and is currently available only for US and Canada Firefox releases. Firefox lets you automatically fill in your saved credit card information on Web forms (for example, when you're ordering something online).

Firefox by default shares data to:

Improve performance and stability for users everywhere

Interaction data: Firefox sends data about your interactions with Firefox to us (such as number of open tabs and windows; number of webpages visited; number and type of installed Firefox Add-ons; and session length) and Firefox features offered by Mozilla or our partners (such as interaction with Firefox search features and search partner referrals).
Technical data: Firefox sends data about your Firefox version and language; device operating system and hardware configuration; memory, basic information about crashes and errors; outcome of automated processes like updates, safebrowsing, and activation to us. When Firefox sends data to us, your IP address is temporarily collected as part of our server logs.

Read the telemetry documentation for Desktop, Android, or iOS or learn how to opt-out of this data collection on Desktop and Mobile.

Set a default search provider

Location data: When you first use Firefox, it uses your IP address to set your default search provider based on your country. Learn more.

Suggest relevant content

Firefox displays content, such as “Snippets” (messages from Mozilla), Add-on Recommendations, Top Sites (websites suggested by Mozilla for first-time Firefox users), and Pocket Recommendations (which is part of the Mozilla family).

Location data: Firefox uses your IP address to suggest relevant content based on your country and state.
Technical & Interaction data: Firefox sends us data such as the position, size and placement of content we suggest, as well as basic data about your interactions with Firefox’s suggested content. This includes the number of times suggested content is displayed or clicked.
Webpage data for Snippets: When you choose to click on a Snippet link, we may receive data about the link you followed. This information is not associated with any other information about you. Learn more.
Webpage, Language, and Location data for Pocket Recommendations: We recommend content to you based on your browsing history, language, and country location. The process of deciding which stories you should see based on your browsing history happens locally in your copy of Firefox, and neither Mozilla nor Pocket receives a copy of your browsing history. To help you see relevant Pocket Recommendations based on your location, Firefox shares your language and country location with Pocket.
Mozilla and Pocket receive aggregated data about the recommendations you see and click. We also share aggregated data about the sponsored content you see and click with our third-party ad platform Adzerk so advertisers can see how many people click on their articles. This aggregated data does not identify you personally.
Location data and Interaction data for Top Sites: When you click the Amazon.com Top Site tile on New Tab, we share your country and the time you clicked with Amazon and AdMarketplace (a third-party referral platform) to verify you navigated to Amazon. Firefox does not share your IP address or any other information that could be used to identify you with either Amazon or AdMarketplace.
Add-on and Feature Recommendations: We recommend Add-ons in two places: the Manage Your Extensions Page (about:addons) and the Awesome Bar, where you search or type in URLs. We may also recommend Firefox Features in the Awesome Bar. We base the recommendations in about:addons on a cookie. We base the recommendations in the Awesome Bar on your interaction with Firefox. Mozilla does not receive your browser history. The process happens locally in your own computer’s copy of Firefox. Learn More about Awesome Bar recommendations or Extensions Page recommendations.

Improve security for users everywhere

Webpage data to DNS Resolver service: For some Firefox users in the United States, Firefox routes DNS requests to a resolver service that has agreed to Mozilla’s strict privacy standards for resolvers. This provides added protection from privacy leaks to local networks and also from certain DNS security attacks. System logs of your DNS requests are deleted from the service within 24 hours and are only used for the purpose of DNS resolution. Learn more or see our default DNS resolver service providers below:

Technical data for updates: Desktop versions of Firefox check for browser updates by persistently connecting to Mozilla servers. Your Firefox version, language, and device operating system are used to apply the correct updates. Mobile versions of Firefox may connect to another service if you used one to download and install Firefox. Learn more.

Technical data for add-ons blocklist: Firefox for Desktop and Android periodically connect to Mozilla to protect you and others from malicious add-ons. Your Firefox version and language, device operating system, and list of installed add-ons are needed to apply and update the add-ons blocklist. Learn more.

Webpage and technical data to Google’s SafeBrowsing service: To help protect you from malicious downloads, Firefox sends basic information about unrecognized downloads to Google's SafeBrowsing Service, including the filename and the URL it was downloaded from.Learn more or read Google’s Privacy Policy. Opting out prevents Firefox from warning you of potentially illegitimate or malicious websites or downloaded files.

Webpage and technical data to Certificate Authorities: When you visit a secure website (usually identified with a URL starting with 'HTTPS'), Firefox validates the website's certificate. This may involve Firefox sending certain information about the website to the Certificate Authority identified by that website. Opting out increases the risk of your private information being intercepted. Learn more.

Crash reports

By default on desktop versions of Firefox, we will ask you to share a report with more detailed information about crashes with Mozilla, but you always have the choice to decline.

Sensitive data: Crash reports include a ‘dump file’ of Firefox’s memory contents at the time of the crash, which may contain data that identifies you or is otherwise sensitive to you.
Webpage data: Crash reports include the active URL at time of crash.
Technical data: Crash reports include data on why Firefox crashed and the state of device memory and execution during the crash.

Firefox Accounts & Join Firefox

Registration data: Mozilla receives your email address and a hash of your password when you create a Firefox Account or sign-up to Join Firefox. You can choose to include a display name or profile image. Your email address is sent to our email vendor, Acoustic, which has its own privacy policy.
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.

Sync

Firefox Autofill Settings

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.

Location

Location data to Google's geolocation service: Firefox always asks before determining and sharing your location with a requesting website (for example, if a map website needs your location to provide directions). To determine location, Firefox may use your operating system’s geolocation features, Wi-fi networks, cell phone towers, or IP address, and may send this data to Google's geolocation service, which has its own privacy policy.

Learn more.

Website notifications

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).

Read the full documentation or learn more, including how to revoke website notifications.

Add-ons

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.
