Selenium Error: org.openqa.selenium.firefox.NotConnectedException

If you run you Selenium test and get following error message, you might have run into compatibility issues – most likely the driver version is incompatible with recently updated Firefox version.

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms

Either upgrade Selenium or downgrade Firefox. In case of local Selenium WebDriver – download most recent Selenium Client & WebDriver Language Bindings. In case of local Selenium Grid 2.0 – download most recent Selenium Server.

This should help!
