好吧，Firefox 40.0 中国版又给我加料了

Where does data sent to the Adjust backend go?

The Adjust SDK is hard-coded to send data to the endpoint https://app.adjust.com. The endpoint is defined by com.adjust.sdk.Constants.BASE_URL at https://hg.mozilla.org/mozilla-central/file/f76f02793f7a/mobile/android/thirdparty/com/adjust/sdk/Constants.java#l27.

The Adjust backend then sends a limited subset of the collected data – limited but sufficient to uniquely identify the submitting device – to a set of advertising network providers that Mozilla elects to share the collected data with. Those advertising networks then confirm or deny that the identifying information corresponds to a specific advertising campaign performed by Mozilla.

What data is collected and sent to the Adjust backend?

The Adjust SDK collects and sends two messages to the Adjust backend.  The messages have the
following parameters:

V/Adjust  ( 6508): Parameters:
V/Adjust  ( 6508):    screen_format    normal
V/Adjust  ( 6508):    device_manufacturer samsung

V/Adjust  ( 6508):    display_height   1184
V/Adjust  ( 6508):    gps_adid         

V/Adjust  ( 6508): Parameters:
V/Adjust  ( 6508):    needs_attribution_data 0
V/Adjust  ( 6508):    app_token        
V/Adjust  ( 6508):    environment      production
V/Adjust  ( 6508):    android_uuid     
V/Adjust  ( 6508):    tracking_enabled 1
V/Adjust  ( 6508):    gps_adid

Notes on what data is collected

The android_uuid uniquely identifies the device.

The gps_adid is a Google Advertising ID. It is capable of uniquely identifying a device to any advertiser, across all applications. If a Google Advertising ID is not available, Adjust may fall back to an Android ID, or, as a last resort, the device’s WiFi MAC address.

The tracking_enabled flag is only used to allow or disallow contextual advertising to be sent to a user. It can be, and is, ignored for general install tracking of the type Mozilla is using the Adjust SDK for. (This flag might be used by consumers using the Adjust SDK to provide in-App advertising.)

It is not clear how much entropy their is in the set of per-device parameters that do not explicitly uniquely identify the device. That is, it is not known if the device parameters are likely to uniquely fingerprint the device, in the way that user agent capabilities are likely to uniquely fingerprint the user.
