controlling Firefox using Perl

Can anyone please point me to decent documentation for controlling 
Firefox using perl?

I am open to any solution, but I have already looked at both 
Selenium::Firefox, and Selenium::Remote::Driver.

I have Selenium::Firefox working on a Centos 7 box, but I can't find any 
documentation on how to use it. So far, all I have managed to do is open 
a web browser window, and get a web page and extract it's contents.

I also have a working Selenium::Remote::Driver setup with a perl script 
on a Centos 7 box controlling IE11 on a Win10 box.

I have spent all day going round in circles with Google finding out of 
date articles, and links pointing back to each other without success. I 
can't even find any doc's on using Selenium::Firefox on the cpan pages 
for the module.

I have gone through dependency hell installing Selenium::Remote::Driver 
on a new Centos 7 box.  I then  installed Java and 
selenium-server-standalone-2.53.1.jar. However, when I try to run a 
script to open a local Firefox window I get the error below on the 
selenium-server.

Again, most of the articles relating this problem are old, circa 2016, 
and refer to version compatibility issues.

Any advice welcome.
