Firefox is opening but terminating immediately when we launch using Selenium WebDriver

When I open Firefox manually, it is opening correctly and functioning as expected but when I try to launch the same Firefox using Selenium WebDriver, code:

WebDriver driver = new FirefoxDriver(); 

Firefox is launching and after few moments am getting error "Firefox has stopped working" with the 2 options:

1. Check online for a solution and close the program
2. Close the program

Please try to resolve this issue as my many of the applications runs on Firefox.
