selenium-firefox-issue

There seems to be an issue with Firefox in combination with Selenium Docker grid. This repo shows the issue. Clone it, run npm install and then:

1. Run npm test to run using local browsers on the local machine. If you have all browsers installed (Edge requires manual installation), the test should pass on every browser.
2. Now run npm test:grid to run the same test on the same browsers but on the Selenium Grid. For me the Firefox one is failing.

I tried adding some console.log statements and the point it fails is in the driver.quit() command. I normally use WebdriverIO and there I see that something seems to goes wrong in the DeleteSession command.

I hope this helps.
