:atrif, if you think that's a regression, could you try to find a regression range using for example mozregression?

Desktop QA has been highlighting this defect as a known issue for several release cycles now, following regression testing. Tim, it would really help us if you set a priority on this bug — it will give us clarity on whether this issue is still worth mentioning in future test reports.

Redirecting this to Paul because he worked on the End Private Session button.

Backlog for now since the feature is not being shipped. At least I'm not aware of any concrete timeline.
