Firefox Button Not in the Panel While Running?

[JakkHakk]

Why isn't there a panel button for Firefox while running? How can I make come to fruition?

You would need to use a panel button rather than a task manager Launcher:
Right click on Firefox in the menu and select Add to Panel.

Task Manager and Expanding Icons Task Manager Launchers expand the Icon into a Task Manager instance.
Icons-only Task Manager leaves the launcher icons unexpanded but still works the same way as a task manager instance would.
All of these stack the individual application instances or separate application windows.

To open a new instance of an application using an already used (expanded) launcher, you would need to right click on the Launcher (Firefox) in the task manager and select "Start New Instance".
