Firefox Suggest Telemetry ========================= This document describes the telemetry that Firefox records for the Firefox Suggest feature. That is, it describes Firefox Suggest telemetry recorded on the client. It also discusses the data that Firefox sends to the Merino service. For information on other telemetry related to the address bar, see the general address bar :doc:`telemetry` document. For information on all telemetry in Firefox, see the toolkit :doc:`/toolkit/components/telemetry/index` document. .. toctree:: :caption: Table of Contents firefox-suggest-telemetry Histograms ---------- The following histograms are recorded for Firefox Suggest. For general information on histogram telemetry in Firefox, see the :doc:`/toolkit/components/telemetry/collection/histograms` document. FX_URLBAR_MERINO_LATENCY_MS ~~~~~~~~~~~~~~~~~~~~~~~~~~~ This histogram records the latency in milliseconds of the Merino source for suggestions, or in other words, the time from Firefox's request to the Merino server to the time Firefox receives a response. It is an exponential histogram with 50 buckets and values between 0 and 30000 (0s and 30s). Changelog Firefox 93.0 Introduced. [Bug 1727799_] .. _1727799: https://bugzilla.mozilla.org/show_bug.cgi?id=1727799 FX_URLBAR_MERINO_LATENCY_WEATHER_MS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This histogram records the latency in milliseconds of weather suggestions from Merino. It is updated in addition to ``FX_URLBAR_MERINO_LATENCY_MS`` and has the same properties. It is an exponential histogram with 50 buckets and values between 0 and 30000 (0s and 30s). Changelog Firefox 110.0 Introduced. [Bug 1804536_] .. _1804536: https://bugzilla.mozilla.org/show_bug.cgi?id=1804536 FX_URLBAR_MERINO_RESPONSE ~~~~~~~~~~~~~~~~~~~~~~~~~ This categorical histogram records a summary of each fetch from the Merino server. It has the following categories: :0 "success": The fetch completed without any error before the timeout elapsed and it included at least one suggestion. (Before Firefox 110.0, this category meant simply that the fetch completed without any error before the timeout elapsed regardless of whether it included any suggestions.) :1 "timeout": The timeout elapsed before the fetch completed or otherwise failed. :2 "network_error": The fetch failed due to a network error before the timeout elapsed. e.g., the user's network or the Merino server was down. :3 "http_error": The fetch completed before the timeout elapsed but the server returned an error. :4 "no_suggestion": The fetch completed without any error before the timeout elapsed and it did not include any suggestions. Changelog Firefox 94.0.2 Introduced. [Bug 1737923_] Firefox 110.0 Added the ``no_suggestion`` category. The meaning of the ``success`` category was changed from "The fetch completed without any error before the timeout elapsed" to "The fetch completed without any error before the timeout elapsed and it included at least one suggestion."

It is updated in addition to ``FX_URLBAR_MERINO_RESPONSE`` and has the same categories. :0 "success": The fetch completed without any error before the timeout elapsed and it included at least one suggestion. :1 "timeout": The timeout elapsed before the fetch completed or otherwise failed. :2 "network_error": The fetch failed due to a network error before the timeout elapsed. e.g., the user's network or the Merino server was down. :3 "http_error": The fetch completed before the timeout elapsed but the server returned an error. :4 "no_suggestion": The fetch completed without any error before the timeout elapsed and it did not include any suggestions. Changelog Firefox 110.0 Introduced. [Bug 1804536_] .. _1804536: https://bugzilla.mozilla.org/show_bug.cgi?id=1804536 FX_URLBAR_QUICK_SUGGEST_REMOTE_SETTINGS_LATENCY_MS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This histogram records the latency in milliseconds of the remote settings source for suggestions, or in other words, the time from when Firefox starts fetching a suggestion from remote settings to the time the suggestion is retrieved. It is an exponential histogram with 50 buckets and values between 0 and 30000 (0s and 30s). Note that unlike Merino, fetches from remote settings happen entirely on the client, so remote settings latencies are expected to be much smaller than Merino latencies. Changelog Firefox 94.0.2 Introduced. [Bug 1737651_] .. _1737651: https://bugzilla.mozilla.org/show_bug.cgi?id=1737651 Scalars ------- The following scalars are recorded for Firefox Suggest.

The pref can be toggled in the following ways: - The user can toggle it in the preferences UI. - The user can toggle it in about:config. The event is also recorded when the user opts in to the online modal dialog, with one exception: If the user has already enabled data collection using the preferences UI or about:config, then the pref's user value is already true. Opting in doesn't change the user value, so no event is recorded. The event's objects are the following: :enabled: Recorded when the pref is flipped from false to true. :disabled: Recorded when the pref is flipped from true to false.

In other words, it is recorded in two cases: - The user picks a Firefox Suggest suggestion or a related UI element like its help button. - While a Firefox Suggest suggestion is present in the address bar, the user picks some other row. The event's objects are the following possible values: :block: The user dismissed ("blocked") the suggestion. :click: The user picked the suggestion. :help: The user picked the suggestion's help button. :impression_only: The user picked some other row. The event's ``extra`` contains the following properties: :match_type: "best-match" if the suggestion was a best match or "firefox-suggest" if it was a non-best-match suggestion. :position: The index of the suggestion in the list of results (1-based). :suggestion_type: The type of suggestion, one of: "sponsored", "nonsponsored", "dynamic-wikipedia" :source: The source of suggestion, one of: "remote-settings", "merino" Changelog Firefox 101.0 Introduced.

The event's objects are the following possible values: :hit: Recorded when an impression cap is hit. :reset: Recorded when a cap's counter is reset because its interval period has elapsed. The implementation may batch multiple consecutive reset events for a cap in a single telemetry event; see the ``eventCount`` discussion below. Reset events are reported only when a cap's interval period elapses while Firefox is running. The event's ``extra`` contains the following properties: :count: The number of impressions during the cap's interval period. :eventCount: The number of impression cap events reported in the telemetry event. This is necessary because the implementation may batch multiple consecutive "reset" events for a cap in a single telemetry event. When that occurs, this value will be greater than 1, ``startDate`` will be the timestamp at which the first event's interval period started, ``eventDate`` will be the timestamp at which the last event's interval period ended, and ``count`` will be the number of impressions during the first event's interval period. (The implementation guarantees that reset events are batched only when the number of impressions for all subsequent interval periods is zero.) For "hit" events, ``eventCount`` will always be 1. :eventDate: The event's timestamp, in number of milliseconds since Unix epoch. For "reset" events, this is the timestamp at which the cap's interval period ended. If ``eventCount`` is greater than 1, it's the timestamp at which the last interval period ended. For "hit" events, this is the timestamp at which the cap was hit. :impressionDate: The timestamp of the most recent impression, in number of milliseconds since Unix epoch. :intervalSeconds: The number of seconds in the cap's interval period. For lifetime caps, this value will be "Infinity". :maxCount: The maximum number of impressions allowed in the cap's interval period. :startDate: The timestamp at which the cap's interval period started, in number of milliseconds since Unix epoch. :type: The type of cap, one of: "sponsored", "nonsponsored" Changelog Firefox 101.0 Introduced.

The timing of the event depends on the experiment and branch. There are two Nimbus variables that determine the timing of the event: ``experimentType`` and the deprecated ``isBestMatchExperiment``. To determine when the exposure event is recorded for a specific experiment and branch, examine the experiment's recipe and look for one of these variables. Listed below are the supported values of ``experimentType`` and ``isBestMatchExperiment`` along with details on when their corresponding exposure events are recorded. :experimentType = "best-match": If the user is in a treatment branch and they did not disable best match, the event is recorded the first time they trigger a best match; if the user is in a treatment branch and they did disable best match, the event is not recorded at all. If the user is in the control branch, the event is recorded the first time they would have triggered a best match. (Users in the control branch cannot "disable" best match since the feature is totally hidden from them.) :experimentType = "modal": If the user is in a treatment branch, the event is recorded when they are shown an opt-in modal. If the user is in the control branch, the event is recorded every time they would have been shown a modal, which is on every startup where another non-Suggest modal does not appear. :isBestMatchExperiment = true: This is a deprecated version of ``experimentType == "best-match"``. :All other experiments: For all other experiments not listed above, the event is recorded the first time the user triggers a Firefox Suggest suggestion. Changelog Firefox 92.0 Introduced. The event is always recorded the first time the user triggers a Firefox Suggest suggestion regardless of the experiment they are enrolled in. [Bug 1724076_, 1727392_] Firefox 99.0 The ``isBestMatchExperiment = true`` case is added. [Bug 1752953_] Firefox 100.0 The ``experimentType = "modal"`` case is added. ``isBestMatchExperiment = true`` is deprecated in favor of ``experimentType = "best-match"``.

Along with remote settings on the client, it is one of two possible sources for Firefox Suggest. When Merino integration is enabled on the client and the user has opted in to Firefox Suggest data collection, Firefox sends everything the user types in the address bar to the Merino server. In response, Merino finds relevant search results from its search providers and sends them to Firefox, where they are shown to the user in the address bar. The user opts in to Firefox Suggest data collection when they either opt in to the online modal dialog or they enable Firefox Suggest data collection in the preferences UI. Merino queries are not telemetry per se but we include them in this document since they necessarily involve data collection. Merino API ~~~~~~~~~~ Data that Firefox sends to the Merino server is summarized below. When Merino integration is enabled on the client and the user has opted in to Firefox Suggest data collection, this data is sent with every user keystroke in the address bar. For details on the Merino API, see the `Merino documentation`_. .. _Merino documentation: https://mozilla-services.github.io/merino/api.html#suggest Search Query The user's search query typed in the address bar. API parameter name: ``q`` Session ID A UUID that identifies the user's current search session in the address bar. This ID is unique per search session. A search session ends when the focus leaves the address bar or a timeout of 5 minutes elapses, whichever comes first. API parameter name: ``sid`` Sequence Number A zero-based integer that is incremented after a response is received from Merino. It is reset at the end of each search session along with the session ID. API parameter name: ``seq`` Client Variants Optional. A list of experiments or rollouts that are affecting the Firefox Suggest user experience. If Merino recognizes any of them, it will modify its behavior accordingly. API parameter name: ``client_variants`` Providers Optional. A list of providers to use for this request. If specified, only suggestions from the listed providers will be returned. Otherwise Merino will use a default set of providers. API parameter name: ``providers``
