How can I open Firefox using a specified Profile without it being the default profile?

I've searched help and community forum, but I cannot find any way to open Firefox using a specific profile other than the default profile. On about:profiles, under the desired profile, there is a button called "Launch profile in new browser," but the browser it opens does not actually have that profile's settings -- it opens a browser with the default profile's settings, and then changing anything in the newly opened browser actually updates the default profile . . . so I must conclude that the button simply opens another browser session in the default profile.

How can I get a browser window in a profile other than the default?

I am using Firefox Quantum, Extended Support Release, 60.6.1esr (32-bit) on Windows 10.

This is done by using the -no-remote command line switch. This is mentioned in the MDN article I posted above.

You would do so using command line options.

You could either use -P "profile_name" or you can use -profile "profile_path" when you launch Firefox.

You do this by appending the command line option to the end of the target value of your Firefox desktop shortcut (since I assume you aren't opening Firefox using the Windows Command Prompt).

Hope this helps.

Perfect! Thanks, Wesley, I'll give it a try.

Well, Wesley's answer got me only halfway to where I need to be. The command line option does not work if there is already a Firefox session open for another profile.

Is there a way to have different Firefox sessions open for different profiles simultaneously?
