Submit data is a Firefox OS feature that allows Mozilla to collect certain non-personal information such as application usage (active use time, counts of opens/closes/crashes and a list of uninstalled apps on Firefox OS devices) and search engine provider information (which search engine provided search results to the device). Firefox OS records this data on a daily basis and sends the data to Mozilla bi-weekly. This data helps us to improve search and performance, identify bugs, understand app usage and create better content offerings on Marketplace.

More specifically, app usage data collected through the Submit data feature will inform Firefox OS and Firefox Marketplace so that we may deliver:

• apps or web content more relevant to your app usage or app usage common in your region through improved content discovery features (such as new collections or featured apps);
• an improved search experience influenced by your app usage and use by region;
• an enhanced user experience of commonly used apps by prioritizing feature improvements and new developments based on the “Submit data” data;
• new content not seen by users before; and
• opportunities to influence the direction of Firefox OS or Firefox Marketplace based on end users’ usage of the phone with beta, A/B testing or prototyping activities.

Search engine provider information, collected through the Submit data feature, will inform Firefox OS so that we may deliver an improved search experience based upon usage trends, such as default search options sensitive to regions and geographies.
