1845338 - Switching channel from esr to release triggers a default prefs reload in post-update processing that creates a new legacy Telemetry client ID

Status: RESOLVED FIXED

(Firefox :: Distributions, defect)

Description

[Mike Kaply [:mkaply]]

We're looking at the migration of Win 7/8 users to the ESR and discovered that a new client ID gets created when migrated.

We think it's related to distribution.ini, not the channel switch.

For the record: this ticket and (we believe) the underlying issue is unrelated to distributions and distribution.ini.

We verified that for release builds Fx 115 the clientID is no longer changing (remains the same) after the migration happens between release and esr for all the platforms affected by this (Windows 7 32/64bit, Windows 8 32/64bit, Windows 8.1 32/64bit, Mac 10.12, Mac 10.13 and Mac 10.14). As per slack, there is no easy way for us to also verify this for Fx 116 and Fx 117 so we can consider this as verified for 115 from QA perspective. If it is required to also verify this for 116 and 117 we can do that but would need the tools to do so. I'll remove the qa-verify+ for now but feel free to re add it if any intervention from QA is required here.
