Cannot Find Firefox Binary when running Selenium Grid2 on Amazon EC2

Question

I've setup my Amazon EC2 instance and I'm able to run my tests and connect successfully, however, I'm unable to run tests for FireFox.

I get the following error...

[remote server] org.openqa.selenium.firefox.internal.Executable(Executable.java):53:in `<init>': Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: LINUX (Selenium::WebDriver::Error::UnknownError)

I've installed XVFB, FireFox, etc.

Answer 1

Solution is to add FireFox location to PATH.
