1271319 - Measure the number of windows opened per "session fragment"

Status: RESOLVED DUPLICATE of bug 1271304

(Toolkit :: Telemetry, defect, P1)

Description

[Alessio Placitelli [:Dexter]]

This is about implementing the count of all windows opened in a session fragment.

Can be based on FX_NEW_WINDOW_MS: https://dxr.mozilla.org/mozilla-central/rev/e5a10bc7dac4ee2453d8319165c1f6578203eac7/browser/base/content/browser.js#3871

Independent window chrome counts as a window; full screen video should not be counted.

Would we need to exclude window open events that were not opened by user actions, say popups?
Or is that negligible for the questions being asked here?

Hmmm, I don't have strong feelings on this. I guess exclude them? Rebecca, do you have any thoughts?

Temporarily dropping this and bug 1271304 to add scalar type support (which would be used for the browser engagement measurements).

If we can count them separately, that could eventually be useful, but if we can only choose one I'd rather we focused on those measures that we can confidently assert came from deliberate user action.

Sorry for flagging you both, but I'm not sure who should answer.

Do we want to include the number of private windows opened in this count? (ditto for the number of tabs opened).

My gut feeling is that we really shouldn't. We're not doing that for the domain/URI count.

I think we probably need to include this. If we want to answers questions related to window usage etc. we should count all windows.
