How to change Firefox profile FOLDER name? (MacOS)

How do I change a profile folder's name without causing any problems? I'm on a Mac. I know I can change a profile's name for ''internal'' Firefox use (by going to '''about:profiles''' in the URL address section of the browser), but the cryptic folder names remain the same. I've read that you should never change a profile folder's name directly (inside ~/Library/Application Support/Firefox/Profiles/), so is there another way? I run both the standard version of Firefox and the developer edition on the same computer, so it would be nice to immediately see which profile folder belongs to which Firefox version by their names.
