Firefox Portable is a 3rd party build that has its own way of launching multiple instances, far different that the official Firefox builds do.
Support for Portable is over here:

That said, Firefox doesn't need to have multiple different Firefox program installations to be able to launch multiple, simultaneous Profiles. That's been a standard feature in Firefox for a number of years now.
