Python selenium does not work with Firefox 47.0

OS : Ubuntu 14.04 64bit selenium 2.53.5 $ firefox --version Mozilla Firefox 47.0

After upgrading Firefox from 46.0 to 47.0 via apt-get, a slenium script does not work with FF47. This script worked well with  FF 46.0.

$ python /home/hattori/Python_works/selenium_Test06.py E ====================================================================== ERROR: test_selenium_Test02 (__main__.SeleniumTest02) ---------------------------------------------------------------------- Traceback (most recent call last):  File "/home/hattori/Python_works/selenium_Test06.py", line 20, in setUp    self.driver = webdriver.Firefox()  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 81, in __init__    self.binary, timeout)  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/extension_connection.py", line 51, in __init__    self.binary.launch_browser(self.profile, timeout=timeout)  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser    self._wait_until_connectable(timeout=timeout)  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 98, in _wait_until_connectable    raise WebDriverException("The browser appears to have exited " WebDriverException: Message: The browser appears to have exited before we could connect.

Here is a temporary solution I found.

remove firefox $ sudo apt-get purge firefox install FF46.0 $ wget https://sourceforge.net/projects/ubuntuzilla/files/mozilla/apt/pool/main/f/firefox-mozilla-build/firefox-mozilla-build_46.0.1-0ubuntu1_amd64.deb $ sudo dpkg -i firefox-mozilla-build_46.0.1-0ubuntu1_amd64.deb $ firefox --version Mozilla Firefox 46.0.1 $ sudo apt-mark hold firefox $ python /home/hattori/Python_works/selenium_test06.py . ---------------------------------------------------------------------- Ran 1 test in 40.916s OK
