Firefox leaves opened browser windows and new tests fail due to connection problem

[Pieras2]

Hi.

I have problem when some tests failure:

• I see multiple opened firefox windows
• browser.end() in after() doesn't seem to close it
• trying to add browser.closeWindow() before end() doesn't help
• new tests fail to conduct due to firefox error that session is already created
  Can anyone help me understand what is wrong and how to make it be closed?

When I test my "tests" I do it on my PC using GUI mode, while on Azure I launch in CLI mode (GUI made problems and maybe the opened windows are the case). I wish tests were going fine in GUI and CLI mode.

I am using nightwatch 1.4.3 and

• code divided into sections, pageObjects
• using async/awaits
