Selenium web driver 2.48.2 does not locate firefox in the default directory.

Package 2.48.2 does not locate the firefox.exe in the default directory any more. It could be relatated to (issue 1287)[https://github.com/SeleniumHQ/selenium/issues/1287]

I have verified this on two different machines, both running studio 2015.1 / Win10. Firefox newly installed in the default location, namely "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"

My suite of tests, which passed recently, are now unable to locate firefox. Firefox is version 42. The latest.

Here is the stack trace:

Try removing com.google.guava_1.6.0 if that is included in your libraries and it should work

I have fixed it by downgrading Firefox from version 43 to 42 and then upgrading it to v.43 again.
