Run Portable, Want To Quantum Desktop

I have been using Portable on a USB drive for some 6 months now, have configured it to my preferences. Thought this was the best way to get to know the new FF.

I will continue to use Portable when I travel on all my laptops, but want to add a permanent desktop version from Mozilla.

I have Waterfox (current) as my default, also have FF ESR (current) on my desktop, as well as Basilisk (Pale Moon derived, current). These were stop gaps while I played with Quantum.

Now, I want to use Portable to configure Quantum on my desktop.

I made some about: config changes around Tab Management, changes needed to play audio when I run Portable in Sandboxie, have the extensions I want, and etc.

What is the best way to install and configure desktop Quantum using Portable's preferences?

If I have to manually configure the desktop version from scratch, where do I see all of the about:config changes I made to Portable?

I really like Portable...A Lot!!

Thanks, in advance.
