The purpose of this prototype is to gather as much feedback as possible, to help us decide whether this feature would work well in Thunderbird, so we will be sending a ping to our servers letting us know which search engine you used, and how you accessed the search feature. To provide further feedback, please leave comments letting us know what you think at http://mzl.la/aNUawh
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.
