Ahahhaa! My error was in just trying it from the command line instead of piping the output of `firefox.exe` to make it output something: Without the pipe, it outputs nothing: `>"c:\Program Files (x86)\Mozilla Firefox\firefox.exe" --version` [download] With the pipe, it outputs the version information, as it should: `>"c:\Program Files (x86)\Mozilla Firefox\firefox.exe" --version \| more Mozilla Firefox 61.0.2` [download]	[reply] [d/l] [select]

`List form of pipe open not implemented` Yes, my update, which I made shortly after posting that node, mentions it: the list from of piped open wasn't implemented on Windows until Perl v5.22. I don't see where naveenp5 mentions that particular error, though? Update: Oh, I see it now (the URL of 902198). I understood that comment to refer to the string pipe, not the error message, but it is a hint that the OP may be on a Perl older than v5.22 - another reason to use a module instead `:-)`	[reply] [d/l] [select]

My perl version is "v5.10.0 built for MSWin32-x64-multi-thread". How do I get that firefox --version working in this older version ?	[reply]

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.	[reply]
