I am receiving the following exception. However, it does appear Firefox is installed in /usr/bin/.

The binary it can't find is geckodriver, not firefox. By default it looks for a binary named geckodriver in your PATH, but you can also pass an explicit location as the binary argument to Geckodriver.
