Filing a bug, since we don't have one on file yet to track the addition of Telemetry probes for the new language switcher. This document collects the initial thoughts and feedback about the kind of telemetry data we'd like to collect https://docs.google.com/document/d/1Ad_QXuyy62WE1KX5oLUAOH0K7FW6IXX3HrLqaACPYlc
@Ben Any advice on what the next steps should be to define the data and start implementing these probes?
This sounds like a good candidate for event telemetry . I think a logical next step is turning the bullets in that doc into well-defined events and ensuring they are feasible to capture. Luca has been working on this for the add-on installation flow in Bug 1433335. Luca: what do you think?  https://firefox-source-docs.mozilla.org/toolkit/components/telemetry/telemetry/collection/events.html

Looking at the google doc attached to comment 0, it seems to me that Bug 1433335 should be able to cover the following ones: - "Time required to download language pack" - "Time required to download dictionaries" which should be covered by the `addonsManager.install` events for the objects "locale" and "dictionary" with the "download_started" and "download_completed" as their "step" extra var.
I suspect this is waiting on more of the UI to be switched over to Fluent, so marking P3 for now.
Priority: -- → P3
The feature that this telemetry is for is being added in 64, I'll take this.
The installs are already being tracked, but we'll want to set the source in the `getInstallForURL` calls. This should involve passing an extra telemetryInfo argument to the call  and we can test that it's set correctly by accessing the `installTelemetryInfo` property on the addon .  https://searchfox.org/mozilla-central/rev/1ce4e8a5601da8e744ca6eda69e782318afab54d/toolkit/components/extensions/parent/ext-management.js#200-205  https://searchfox.org/mozilla-central/rev/1ce4e8a5601da8e744ca6eda69e782318afab54d/browser/components/extensions/test/browser/browser_ext_management.js#73-76
Here's the data review request document for the UI interactions. I have another document for bug 1502921 that will be category 1, if it's easier to combine them let me know.

Comment on attachment 9021596 [details] data-review.txt Asking :liuche for data review. I think these events need another pair of eyes, especially when it comes to the identifiers "dialogId" and "installId"

Comment on attachment 9021596 [details] data-review.txt 1) Is there or will there be **documentation** that describes the schema for the ultimate data set available publicly, complete and accurate? Yes, in telemetry/Events.yaml 2) Is there a control mechanism that allows the user to turn the data collection on and off? (Note, for data collection not needed for security purposes, Mozilla provides such a control mechanism) Provide details as to the control mechanism available. Yes, can be turned off in Firefox data controls 3) If the request is for permanent data collection, is there someone who will monitor the data over time?** No, expiration in 70 4) Using the **[category system of data types](https://wiki.mozilla.org/Firefox/Data_Collection)** on the Mozilla wiki, what collection type of data do the requested measurements fall under? ** Type 2 - user interactions with dialog switcher 5) Is the data collection request for default-on or default-off? default on for release (opt-out), and beta, nightly 6) Does the instrumentation include the addition of **any *new* identifiers** (whether anonymous or otherwise; e.g., username, random IDs, etc. See the appendix for more details)? No, collecting action names 7) Is the data collection covered by the existing Firefox privacy notice? **If unsure: escalate to legal if:** Yes 8) Does there need to be a check-in in the future to determine whether to renew the data? (Yes/No) (If yes, set a todo reminder or file a bug if appropriate)** Expires in 70

We have an r+ but this hasn't landed yet. Also, what's the plan for bug 1502921?
