Comment 69 for bug 856072

Note that the Android Market gives us numbers of "Active Installs", which I believe counts devices that are active (i.e. still pinging the Market server) and currently have Firefox installed (i.e. have not uninstalled it).

This is very different from our own "Active Daily Users" metric based on blocklist pings, which only counts actual usage.

We currently have a total of about 2,700,000 "Active Installs" but only about 330,000 "Active Daily Users". Comparing usage metrics is impossible unless you actually specify which metric you are talking about.
