Hi All,

While trying to run the selenium java script I am getting the following error each time it is trying to launch Firefox.
[b:1mfge9x4]Note[/b:1mfge9x4]: I have already run so many scripts and it was launching firefox successfully.I have not made any changes in any of the settings also. But, now all of a sudden it is throwing error.
Please help asap.

Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

Hi,

I reinstalled firefox and problem persists. My code had worked a few times and then suddenly it stopped working. It never works now. I have just a simple program from module 11. Code:

import org.openqa.selenium.firefox.FirefoxDriver;
public class BrowserTests {

public static void main(String[] args) {
FirefoxDriver fd = new FirefoxDriver();
fd.get("http://www.bbc.com");
fd.getTitle();

}

}

My Browser info:
Build identifier: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0

Note:
while uninstalling, I had also manually deleted mozilla folders and mozilla/firefox entries from windows registry

use firefox version 42

Reverting to firefox version 42 did the trick!

When firefox opens it initially says that the URL is not valid (like it did before), but now, that message is overlaid by the URL (http://www.bbc.com) and in Eclipse console, the messages are correct.

Thank you so much!
