Error FF Browser not working for Selenium test after update

0 votes

On my Ubuntu Desktop 16.04, Selenium WebDriver cannot open browser for testing. Before updating, it was all fine, but after updating Firefox I get the following error:

Traceback (most recent call last):
  File "test.py", line 6, in <module>
    driver = webdriver.Firefox()
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 81, in __init__
    self.binary, timeout)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/extension_connection.py", line 51, in __init__
    self.binary.launch_browser(self.profile, timeout=timeout)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser
    self._wait_until_connectable(timeout=timeout)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 98, in _wait_until_connectable
    raise WebDriverException("The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

Since Firefox's latest update to version 47.0, a new driver must be used. Probably because of Mozilla updating their terms and policies of use. To get things running, either use: 

1. Marionatte driver which is an extension to the Firefox browser

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
Webdriver driver = new FirefoxDriver(capabilities);

2. Use Gecko driver which is the driver provided by Firefox for selenium tests

system.setproperty("webdriver.gecko.driver","path to geckodriver.exe");
WebDriver driver = new FirefoxDriver();
