New Profiles attaching to a Current Profile
II'm using Win 10 Pro and am having an issue with adding new FF profiles.
I have a shortcut icon in the (bottom) Win 10 taskbar. I've created new FF profiles with unique names and paths, etc. But when I open FF as one of those profiles the open window(s) "attach" to an icon / shortcut in the taskbar, even tho' that icon / shortcut has a completely different target (i.e., path for starting FF).
I don't want windows from Profile New 1 or Profile New 2 to look as if they are for Profile Icon_in_the_Taskbar.
I hope this makes sense. I've created profiles in the past and didn't run into this problem so perhaps it's me. But I also don't believe I'm doing anything different than before.

For taskbar icons to be grouped separately, you need to go to about:config in both profiles and create taskbar.grouping.useprofile (Boolean) with value true and also set browser.startup.blankwindow to false. Pin the resulting taskbar icons and edit the command line parameters by holding down the Shift key while right-clicking > Properties.
