Please help!

Hi Santi,

I am using this implementation in JAVA, with latest version of Selenium and Firefox. It works fine in Chrome, but
I am getting the below error in firefox -

org.openqa.selenium.UnsupportedCommandException: Unrecognized command: POST /session/fd481a91-f664-114b-8363-f4a64ee30518/file

Can you help me out?

This procedure fails for me when the file in question is large. In my case, it's ~1.6GB. When I do this to a remote Selenium grid I have, it get an error that Java is out of heap space. Not sure how to fix that since I've already given both the hubs and the nodes a 16G max heap.

file_detector needs updated to str if File.exist?(str) and File.file?(str) to follow a bug with string "." being treated as a folder
