You can put a standalone portable in a system folder, but they can also be most other locations.
When you put a browser out of the system, it will commonly not run with restricted permissions, logically, when it will run as root.
That is just wrong. The permissions of a process depends on the user who started, not on the location (where is it stored).
Again, all of the processes inherit permissions/rights/ownership from the parent process (where they were started from). Only root has right to modify it. The location of the binary is completely irrelevant.
The access to any file/dir depends on the current user and group (of the process, which wanted to access it), and the access rights of the given path.
