Telemetry takes care of doing the right thing for histograms, scalars & events internally. The opt-in for additional Telemetry data went away instead we always collect less data on Firefox release.įor most Firefox development, nothing should change. What does this mean for me?įor Firefox users, there is no significant change the data upload setting users chose is respected as before. While this has broader technical impact on Firefox data collection, the changes we landed should make this work mostly seamless. (For some specific features or studies there may still be explicit opt-in notifications, but this covers all standard Firefox data collection.) So for Firefox we now just differentiate between “release data” and “prerelease data”. Individual measurements are now collected from either all users or prerelease users.

There is just one control for data upload for Firefox, which is on by default.

Turning off “opt-out” Telemetry also turned this off.

“opt-in” or “extended” Telemetry: This was off by default on Firefox release and on by default on prerelease channels.

“opt-out” or “base” Telemetry: This was on by default on all Firefox channels.

Previously we had two different sets of data we collected: However, it does have some technical consequences for Telemetry that we landed in Firefox 58.

There is a new control for SHIELD studies, which i won’t detail here.Īs detailed in another post, this doesn’t change anything about the type of data being collected while it makes the data controls less confusing.

There is only one control now for Firefox data submission.

There are two notable changes here to previous versions: How the new Firefox data preferences look.
