Unable to execute scripts against Firefox in text execution pane

[osburn...@gmail.com]

I am able to execute scripts against firefox from the test plan module but executing the same script from test execution does not work.  If I set Marionette to false, an empty firefox browser is launched and displayed for 45 seconds before the script fails.  If I set Marionette to True in the configure browsers window for firefox, the script fails immediately. 

Console for marionette set to true shows:  "Unable to find a matching set of capabilities"

Console for marionette set to false shows:  "Timed out waiting 45 seconds for Firefox to start."

Please share following details,

- console log of execution

- firefox browser version

- gecko driver version used

How are you setting the Marionette driver here?
