Because this is the definition of opt-in data collection ("can we collect
this data? Sure, I'm in!"), which has the data quality issues already
mentioned. Opt-out data collection means that by default we would be
collecting the data, unless the user goes to the preferences panel and opts
out of it (there is also a notification bar for every new installation to
remind users of this policy and how to opt out).
There is already both opt-out data collection going on (e.g. longest cycle
collection pause) and opt-in data collection (e.g. whether the device
supports touch input) in Firefox. The differential privacy approach of
RAPPOR we believe gives us the mathematical proof that we can collect some
of the more privacy-sensitive data in a way that doesn't reduce user
privacy.
And to reiterate the obvious: we don't collect user data to build user
profiles and we never want to. We are not in the advertising business, we
are a non profit working for the public benefit. We will always be
providing ways to disable data collection, even for the non personal
identifying information we need to collect in order to improve the browser.
We believe the academic research of the last few years on differential
privacy has figured out ways to collect data without infringing on user
privacy. Apple, Google and others are already using the fruits of this
research in their products. If there are reasons to believe these methods
aren't working well enough, we would very much like to know about them!
