I am getting this error when trying to run a very simple selenium script via java. This gets thrown a while after trying to create a new FireFoxWebDriver()

I have seen similar errors posted but they are quite old and none seem to have good solutions. I am using selenium-java and selenium-firefox-driver both version 2.51.0. My firefox version is 43.0.2, the selenium site says they support the latest version of firefox, so I assumed this wasn't the issue.

Any help is much appreciated, thanks!

Check your transitive dependencies and make sure you're definitely using the version of Selenium you think you are (2.51.0)

Looking back through the history of FirefoxDriver, its call to connection.start() hasn't been on line 247 for a very long time (like, 2014). It's currently on 271.

I suspect you're on/around 2.40.0 due to another WebDriver component overriding your preferred version. In which case you probably are subject to the same problems that others have been in the past.

See: Why am I getting the selenium error 'firefox-bin quit expectedly' and unable to connect to host 127.0.0.1 on port 7055 et al.

Update: In fact, there's confirmation if you read 2/3rds of the way down:

Build info: version: '2.42.2', revision: '6a6995d31c7c56c340d6f45a76976d43506cd6cc'

The consensus seems to be that the problem is a version incompatibility, therefore you should upgrade to a recent WebDriver version.

If you are using selenium version 3: 

System.setProperty("webdriver.gecko.driver","C:\\Users\\vipin\\Downloads\\Compressed\\geckodriver.exe");

If the above property is not working or opening the application in your browser, then try the following: 

System.setProperty("webdriver.firefox.marionette","C:\\Users\\vipin\\Downloads\\Compressed\\geckodriver.exe");
