Can't start any server.

[rafaleo]

Hello. I use commands in exactly same way as before:

rS <- rsDriver(browser = "firefox", port = 4564L, version = "3.8.1")
rP <- rsDriver(browser = "phantomjs", port = 4567L)
rG <- rsDriver(browser = "chrome", port = 4568L)

but everytime I change driver or version I got error message and browsing is impossible. I did change anything since it worked few months ago or did I? Can you infer something from these error messages?

I found my old FF50+ was probably too old to start the server. It worked with new version, thanks to this post: https://github.com/ropensci/RSelenium/issues/156 However, I'd love to be able to work with my old FF because I have many useful addons which don't work with new versions.
