I'm running a browser extension (or should I say "add on"?) which requires the presence of a so called "companion app".
In a non-portable environment such an app has to be installed in the main OS, as well as the browser itself.
I'm wondering whether there is a way to "install" such an app inside the FF Portable's folder, in order to carry it around together with the browser, in a USB key or similar device.
PS. I searched, before posting, for similar questions but did not find any.
