Environment
===========
The environment consists of data that is expected to be characteristic for performance and other behavior and not expected to change too often.
Changes to most of these data points are detected (where possible and sensible) and will lead to a session split in the :doc:`main-ping`.
The environment data may also be submitted by other ping types.
*Note:* This is not submitted with all ping types due to privacy concerns. This and other data is inspected under the `data collection policy <https://wiki.mozilla.org/Firefox/Data_Collection>`_.
Some parts of the environment must be fetched asynchronously at startup. We don't want other Telemetry components to block on waiting for the environment, so some items may be missing from it until the async fetching finished.
This currently affects the following sections:
- profile
- addons

Settings
--------
defaultSearchEngine
~~~~~~~~~~~~~~~~~~~
Note: Deprecated, use defaultSearchEngineData instead.
Contains the string identifier or name of the default search engine provider. This will not be present in environment data collected before the Search Service initialization.
The special value ``NONE`` could occur if there is no default search engine.
The special value ``UNDEFINED`` could occur if a default search engine exists but its identifier could not be determined.
This field's contents are ``Services.search.defaultEngine.identifier`` (if defined) or ``"other-"`` + ``Services.search.defaultEngine.name`` if not. In other words, search engines without an ``.identifier`` are prefixed with ``other-``.
defaultSearchEngineData
~~~~~~~~~~~~~~~~~~~~~~~
Contains data identifying the engine currently set as the default.
The object contains:
- a ``name`` property with the name of the engine, or ``NONE`` if no
engine is currently set as the default.
- a ``loadPath`` property: an anonymized path of the engine xml file, e.g.
jar:[app]/omni.ja!browser/engine.xml
(where 'browser' is the name of the chrome package, not a folder)
[profile]/searchplugins/engine.xml
[distribution]/searchplugins/common/engine.xml
[other]/engine.xml
- a ``submissionURL`` property with the HTTP url we would use to search.
For privacy, we don't record this for user-installed engines.
``loadPath`` and ``submissionURL`` are not present if ``name`` is ``NONE``.
searchCohort
~~~~~~~~~~~~
If the user has been enrolled into a search default change experiment, this contains the string identifying the experiment the user is taking part in. Most user profiles will never be part of any search default change experiment, and will not send this value.
userPrefs
~~~~~~~~~
This object contains user preferences.
Each key in the object is the name of a preference. A key's value depends on the policy with which the preference was collected. There are two such policies, "value" and "state". For preferences collected under the "value" policy, the value will be the preference's value. For preferences collected under the "state" policy, the value will be an opaque marker signifying only that the preference has a user value. The "state" policy is therefore used when user privacy is a concern.
The following is a partial list of collected preferences.
- ``browser.search.suggest.enabled``: The "master switch" for search suggestions everywhere in Firefox (search bar, urlbar, etc.). Defaults to true.
- ``browser.urlbar.suggest.searches``: True if search suggestions are enabled in the urlbar. Defaults to false.
- ``browser.urlbar.unifiedcomplete``: True if the urlbar's UnifiedComplete back-end is enabled.
- ``browser.urlbar.userMadeSearchSuggestionsChoice``: True if the user has clicked Yes or No in the urlbar's opt-in notification. Defaults to false.
