Add option to disable icon of private window on taskbar

[Progress2000]

Since updated Firefox beta to version 104, a new icon will pop up on taskbar when I open a new private window. I find this very inconvenient. Is it possible to add an option to disable this icon and return to the original behavior before v104 without using about:config?

I believe it's quite necessary feature now, to differ the context in an easy way to access from the taskbar.
