I've been checking this out, and I was wondering if there was a way to run both a local and a portable version of firefox at the same time?

Nope. Youll have to delete the function in each one of looking for other firefox.exe processes. you can, as you are supposed to modify it without sharing it.
you can, if you read the readme in App\Other\Source then it will explain how. It is important to note however that this might leave files behind and is not supported.
