There are several types of Firefox user data that would be useful to help guide product decisions and provide visibility about how users customize Firefox. There are the following "per user" data sets:
- Static metrics [S] (e.g. current number of bookmarks)
- Dynamic metrics [D] (e.g. average number of search done per session)
- Web metrics [W] (e.g. number of images per page)
- Unique metrics [U] (metrics only a browser could figure out, e.g. how often a user encounters Flash)
- Trend data of static and dynamic metrics [T] (e.g. average number of open tabs across sessions).
In addition, aggregated metrics from all user data collected can be calculated.
- Average static metrics [aS]
- Average dynamic metrics [aD]
- Average web metrics [aW]
- Average trend metrics [aT]
Other stats include low/high values across all users.
