SUMMARY

the pinned icon behavior of the firefox icon in the icon only task manager is not as expected after a firefox update, and subsequent reboot... the previously pinned icon no longer groups new windows and it can no longer be shorted manually by dragging... and if unpinned, leaves behind a generic icon image rather than going away.

instead, after an update and a new window is opened, a new icon appears that collects and groups all the new windows, leaving the previously pinned icon abandoned.

to resolve, unpin all the icons, close firefox, navigate to the firefox app in the apps menu and pin to taskmanager... from there the icon can sorted, used to launch firefox and collect new windows (until the next firefox update).

STEPS TO REPRODUCE
1. pin firefox icon to the taskmanager
2. open firefox and use until an update is ready
3. close firefox to accept the update and reboot after update is completed.

OBSERVED RESULT
previously pinned icon no longer behaves normally and a new (duplicate icon) appears in the task manager.

EXPECTED RESULT
previous icon would remain associated with the updated version of firefox and behave normally for sorting and grouping functions.

Unfortunately this was caused by metadata changes in Firefox's own packaging that caused the Task Manager to identify it as a new app after the update. It's super annoying because there isn't anything in KDE we can do to make it better for people who already had the "old" Firefox pinned to their Task Manager. Unpinning the old one and re-pinning the new one is unfortunately the expected way to proceed here.
