It seems to me the leaderboard considers only Stumbler users, while
I'd wager the vast majority of contributions come from Firefox for
Android users. There are more than 100 millions downloads of Firefox
for android. Even if only 1 out of 5000 users have opted in and still
use the app consistently, that's 20000 contributors.
