1582161 - Firefox processes not grouped in Windows 10 task manager

Status: UNCONFIRMED

(Toolkit :: Performance Monitoring, defect, P5)

Description

[Jesse Roland]

Attachment: Firefoxtask.PNG

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

1.) Use Firefox as normal.
2.) When first started all Firefox processes are grouped in Task Manager.
3.) After using Firfox for at least several minutes processes begin to uncouple from task manager making it difficult to monitor for memory and CPU usage through Windows.

Actual results:

1.) Not all processes grouped under task manager.
2.) This appears to regroup after a certain period of time.

Expected results:

1.) All Firefox processes should stay grouped under task manager so that we can accurately track CPU and Memory usage.
2.) Image is not an accurate representation of the issues as when filing the bug the processes rejoined as they should have been.

Hi @Jesse Roland, cannot reproduce- I've tried on Windows 10 using nightly 71.0a1, beta 70.0b8, release 69.0.1. If you have any other info to provide please add them. Further, I will add a component, if isn't the proper one please fell free to change it.
Regards,
Liviu

It happens intermittently, I have to keep Task Manager open and check intermittently to see the issue.
