Scope and site identity
This Privacy Policy applies to firefoxappx.com itself. The site publishes independent information about Firefox, including product features, download links, troubleshooting guidance and browser comparisons. It is not an official Mozilla Foundation, Mozilla Corporation or Firefox website.
Because of that distinction, this page only describes data that may be processed when you visit firefoxappx.com. If you install or use Firefox, sign in to a Mozilla account, enable Firefox Sync, install add-ons, use AI features or interact with other Mozilla services, those activities are governed by Mozilla's own privacy notices and service terms.
Site data we may process
When you visit firefoxappx.com, the site's hosting, CDN, security or infrastructure providers may automatically process basic technical information such as:
- Access and network data: IP address, browser type, device or operating-system information, request time, requested URL, referrer, response status and similar server or security-log data.
- Necessary site-state data: cookies, local storage or similar technologies used to remember language, page state, security controls or other necessary site behavior.
- External-link activity: when you follow a link to Mozilla, Google Play, the App Store, social platforms or another third-party service, further data handling is controlled by that destination.
- Information you submit voluntarily: if the site later adds contact, feedback or form features, information you choose to submit would be processed for the purpose shown with that feature.
firefoxappx.com does not operate Mozilla accounts, Firefox Sync, Firefox telemetry or Firefox crash-reporting infrastructure, so those product datasets should not be described as data collected by this site.
Cookies, logs and external services
Site logs, cookies or local storage may be used where needed to deliver pages, maintain security, troubleshoot errors, remember language or interface state, and detect abusive or abnormal requests.
- Serve pages, static assets and other necessary site functionality;
- Detect malicious requests, attacks, abuse or abnormal automated traffic;
- Investigate loading failures, broken assets, infrastructure problems or compatibility issues;
- Complete normal redirects when you choose to visit Mozilla, an app store, a social network or another third-party service.
If firefoxappx.com later adds analytics, advertising, user accounts, forms or other features that materially change data processing, this policy should be updated to explain those changes. Third-party cookies, pixels or tracking technologies used after you leave this site are governed by the destination's own privacy and cookie notices.
Mozilla and Firefox data boundary
Firefox product data is governed by Mozilla's Firefox Privacy Notice, currently effective May 4, 2026. That notice covers categories such as technical and settings data, interaction data, system performance data, and additional information processed for specific Firefox features.
Mozilla distinguishes between data that normally stays on your device and data that may interact with Mozilla or service providers. Browsing history, form data, cached web content and cookies often remain local, while technical and interaction data, New Tab features, crash reports, add-on updates and some optional features may involve Mozilla or third-party services.
Mozilla accounts and Firefox Sync have their own privacy rules. Mozilla's current Mozilla Accounts Privacy Notice was updated August 10, 2026. If you enable Sync, Mozilla receives synced data in encrypted form; supported data can include tabs, add-ons, passwords, autofill information, bookmarks, history and preferences. Mozilla states that Sync uses end-to-end encryption and that Mozilla cannot decrypt the synced content.
For Firefox product data, review the official Mozilla Firefox Privacy Notice. For account and Sync data, review Mozilla's separate Accounts Privacy Notice.
Security and data retention
firefoxappx.com may use reasonable technical and administrative safeguards to reduce the risk of unauthorized access, misuse, disclosure or destruction. No method of internet transmission or online storage, however, can be guaranteed to be completely secure.
Retention periods for server logs or infrastructure data may depend on the site's host, CDN, security provider and operational needs. Data should not be kept longer than reasonably necessary for security, troubleshooting, compliance or site operations, while third-party providers follow their own retention policies.
Your choices and rights
Your controls depend on whether the data belongs to firefoxappx.com or to Mozilla's Firefox products and services.
- Clear cookies, local storage and cached site data through your browser settings;
- Choose whether to follow links from firefoxappx.com to Mozilla, app stores, social platforms or other third parties;
- Manage Firefox technical and interaction data, crash reporting, New Tab features and other configurable product settings inside Firefox;
- Use Mozilla's privacy and account channels for requests involving Mozilla accounts, Firefox Sync or other Mozilla-controlled data.
Depending on the law that applies to you, you may also have rights to access, correct, delete, restrict, object to or export personal data. Requests about firefoxappx.com should be directed to this site; requests about Mozilla-controlled data should be directed to Mozilla.
Contact, third-party notices and updates
Questions about data handled by firefoxappx.com should use the contact method published by this site. Questions about Firefox, Mozilla accounts, Firefox Sync, technical and interaction data, crash reports, AI features or add-ons should be directed to Mozilla's privacy and support resources.
This policy may change when site functionality, infrastructure, third-party services or applicable requirements change. The 'Last updated' date on this page will be revised when the policy changes materially.
