Web browser doesn't open in RSelenium

问题

I'm trying to move my first steps with RSelenium so after setting up server I launched

 remDr <- remoteDriver(remoteServerAddr = "192.168.99.100", port = 4445L, browserName = "firefox")
 remDr$open()

Everything looks fine, I'me able to navigate and so on, unfortunately I can't see my session because browser doesn't open. How can I fix it?
