firefox: automatically sends some data to Mozilla
Last modified: 2013-05-29 08:07:40 EDT
Description of problem:
Firefox displays the following message: "Firefox automatically sends some data to Mozilla so that we can improve your experience."
This is different from the previous prompt, which offered a clear yes/no choice the second time Firefox was started. (Upstream no longer prompts and enables exfiltration by default, it seems.)
Version-Release number of selected component (if applicable):
Unclear. I couldn't reproduce it in a sandbox.
Firefox suggest it shares data about my web surfing with Mozilla without my explicit consent.
Firefox does not share such data with Mozilla.
I tested some upstream versions and found this:
Firefox 21 automatically enables "Firefox Health Report" and "Crash Report", without prompting the user.
Firefox 20 only enables "Crash Report".
Firefox 19 was the last version that prompts on the second start, but it still enables "Submit crash reports" even if the user opted out. It's not clear to me if any data is sent for crash reports, sending SIGSEGV still results in a confirmation dialog.
As for the health report, see https://blog.mozilla.org/metrics/fhr-faq. You can control it by "datareporting.healthreport.uploadEnabled" or "datareporting.healthreport.service.enabled" preferences in about:config.
The crash report submit still has to be confirmed by user - so you can disable it.
Another thing is that we don't have check boxes for that in Preferences/Advanced as the upstream firefox - we should investigate it.

I'm still concerned that the message may give users the impression that Firefox sends data to Mozilla even if it doesn't (by default). We shouldn't claim that we have a privacy leak.
