Well, due to some issue, users are recommended
to update Portable Firefox by new installation.
But which directory should be selected during update installation?
Portable Apps->Firefox Portable?
Or some other in the pen-drive directory tree?
By default Portable Firefox installation selects "\FirefoxPortable"
as the installation folder. What is the root of this path?
To the pen-drive's root? Or C:\Program Files?
What if more than one pen-drives are mounted?
