I am running some Selenium-Tests. When I start them directly from Eclipse everything works fine. But when I Start them through Maven there the following Exception occurs:
If you've updated both Firefox and Selenium to the latest versions in trying to fix this issue, and you are still facing the problem, you may have updated Firefox using "Restart to update".
Shutdown Firefox and ensure that the Firefox executable is no longer running. Then try your test. It should work now.
I'm guessing this is related to when exactly the Firefox binary is updated when you use "Restart to Update"
