This document describes what user data goes to Mozilla and Mozilla's commitments regarding that data. In order to determine how and how often our users use this addon, we send the currently-selected search engine and the method chosen (menu, context-menu, global search, or clicking a link) over secure channels to a Mozilla server. This data is retained by Mozilla in its original form for 10 days for debugging purposes only. After that, it is retained in aggregate form only. We may release reports containing aggregated, anonymized summaries of the data to the community to aid in product & design decisions.
