I switched to Selenium 3 and started using Chrome instead of Firefox. I discovered that for Chrome I need to download a binary for WebDriver to handle the browser. For that to work I need to set absolute path to this binary as Java variable. If binary gets updated, I need to update that binary manually in my test framework - which takes time and is really annoying. I discovered a very neat Java library that does it for me: https://github.com/bonigarcia/webdrivermanager
