What is the string (about: config => prefs.js) for giving FF permission to save to external disk?

Hi, my updated Firefox (66.0.5 64 bit) can't save to external media (USB) and internal ntfs disks anymore - access denied...(Linux-Partitions work; as well as the USB-Sticks and the "Windows"(NTFS)-Partitions via file manager). Changed permissions (via software-panel) are not saved. I tried refreshing, reinstalling and other suggested solutions, nothing works. So i plan to override/complement the prefs.js with a (at the moment non-existant) user.js in the profile folder, but i cannot find the neccessary string to do this (i searched in about:config without success). Maybe changing its value in about:config would be enough.

Does anyone know how this string looks like?

Thanx in advance! Donnie_

External USB sticks (and possibly other partitions) are usually mounted with the owner as root and this would imply that you can't write to such a device (i.e. likely read-only) as a normal user. You would have to change the permissions and make sure that you have read/write permission.
