Firefox Lite Privacy Notice

Improve performance and stability for users everywhere

• Interaction data: Firefox Lite sends data about your interactions with Firefox Lite to us (number of webpages visited; and session length) and Firefox Lite features offered by Mozilla or our partners (such as interaction with Firefox Lite search features and search partner referrals).

• Technical data: Firefox Lite sends data about your Firefox Lite version and language; device operating system and hardware configuration; memory, basic information about crashes and errors; outcome of automated processes like updates, and activation to us. When Firefox Lite sends data to us, your IP address is temporarily collected as part of our server logs.

Suggest relevant content

Firefox Lite displays content, such as Top Sites (websites suggested by Mozilla for first-time Firefox Lite users).

• Technical & Interaction data: Firefox Lite sends us data such as the position, size and placement of content we suggest, as well as basic data about your interactions with Firefox Lite's suggested content. This includes the number of times suggested content is displayed or clicked and time spent engaging with suggestions. This also applies to “Life Feed” which is non-targeted localized news, games, deals and more offered by our partners in certain countries. See here for more details.

• Content data: Some partners of suggested content send us aggregate metrics on the types of content people engage with, for example, sports or news.

Measure and support our marketing

• Referral and Campaign Data: To help improve our marketing campaigns, Firefox Lite may use “Referral Data” such as the website domain or advertising campaign that referred you to download and install Firefox Lite. This data is kept by our analytics vendor and provided when you start Firefox Lite, and also includes a Google advertising ID, timestamp, country, locale, operating system, and app version. We may also use third party vendors to manage referral programs and handle any data that you choose to submit.

Improve our product

To help us improve performance, support crashes, offer new features, and understand your experience with Firefox Lite and improve the user experience through A/B testing and in-product messaging, Firefox Lite uses Google’s Firebase platform, which receives data from your device. Learn more about Firebase data collection or turn off “Send Usage Data” in your Settings.

Search

You can perform searches directly from the search bar in Firefox Lite. Mozilla does not receive your search queries. Query data is sent to your search provider, which has its own privacy policy.

• Search Suggestions: Firefox Lite by default sends search queries to your search provider to help you discover common phrases other people have searched for and improve your search experience. These data will not be sent if your selected search provider does not support search suggestions.

Location

• Location data to Google's geolocation service: Firefox Lite 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 Lite 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.
