The screeshots shows functionality that the current profile/profile launch UI already has. Choose, create, ask on startup.
Right now it's hidden behind a startup parameter. But honestly, I would prefer a UI between the current one and the new one. That screenshot looks like it would reduce usability through big spacing and suboptimal alignment. At least judging by my preferences.

I guess adding a picture is nice. But does it have to be that huge and prominent?
This only works on Windows. For Macs and maybe Linux, you have to run this command to bring up a different profile:
/Applications/Firefox.app/Contents/MacOS/firefox -p
As best I can tell, there's no way to make this into a shortcut that you could just click on. This change will be good and allow me to launch them without invoking that command in terminal several times after rebooting my computer.
In Windows it's the same. Though the parameter is
-P(uppercase) not-p. That's why the comment said "it’s hidden behind a startup parameter".I dont know about Mac, but in Linux you can just manually make a
.desktopfile to have as a shortcut to callfirefox -P, or better a shortcut to a specific profile withfirefox -P <profile>. Though what I often do is keep a bookmark toabout:profilesand open a new window from there.I might try this next time I launch. Just launch one, go into profiles, and launch the second one.
