Reason\r
======\r
-Selenium server does not know where to find the firefox binary (even though it is in ``$PATH`` and in the standard ``/usr/bin/firefox`` on Ubuntu 17.04)\r
+Selenium server does not know where to find the firefox *gecko driver* binary.\r
\r
-Solution\r
-========\r
-Pass the firefox path when starting selenium server::\r
-\r
- $ java -jar -Dwebdriver.gecko.driver=/usr/bin/firefox selenium-server-standalone-3.6.0.jar\r
+Note that you CANNOT simple use /usr/bin/firefox, you need https://github.com/mozilla/geckodriver/
