My perl version is "v5.10.0 built for MSWin32-x64-multi-thread".

Please note that Perl 5.10.0 is more than 10 years old, I recommend considering an upgrade.

How do I get that firefox --version working in this older version ?

As I said, I strongly recommend using one of the modules I mentioned. Yes, even you can use CPAN, and at least Strawberry Perl 5.10.0 includes IPC::Run3.
