dedicated profiles per channel (bug 1373244), hopefully in Firefox 59,
to help address profile corruption issues our users can encounter when
using a profile previously used on a later version.<br></div>Once it
gets implemented we'll have more profiles on telemetry and it probably
impacts the interpretation we have of our telemetry data. A solution may
be to implement a correlation ID between different profiles although
current datasets and analysis would likely be impacted.<br></div><div><br>If there are specific concerns about this please let me know since we’re still at scoping stage.<br><br></div><div>Thanks,</div>Romain</div>
