I want to run portable apps like Firefox on a separate storage drive;
such as a USB, HDDrive, SSDrive.
Gentoo, Debian, and RPM distros run portable apps on separate storage drives.
It is not running for me on Slackware Distros.
Here is a link to portable "self-contained" Firefox.

I do not want to run it on the same partition and drive as the OS/Slackware.
