I run Firefox in portable mode in Windows 10. It works wonderfully. However, when i click on web links outside of FF, it loads Chrome. So in FF I go to options and set it as a default. In "default apps" it shows up there. But Because I am running FF portable, by setting it as default browser, it creates a new profile on c:\users\username . And loads a whole new instance of FF. That is not what I would like to happen.

Is there a way to set it up so that when I click a link in an email, it will load the FF from the portable instance? using the profile within the portable directory. Usually I always have FF open. It is never closed.
