Your quoting does not match how the Windows shell (cmd.exe) processes quotes.

cmd.exe does not recognize a backslash before a space as the intention to quote that space. A working invocation of firefox.exe could be:

my $ff_exe = q{C:\\Program Files\\Mozilla Firefox\\firefox.exe};
my @cmd = ($ff_exe, '--version');
my $shell_command = join " ",                    # separate by spaces
                    map { /\s/ ? qq{"$_"} : $_ } # enclose in double q
+uotes if needed
                    @cmd;
print $shell_command;

Note that under Windows, the --version command line switch does not output anything.
