This happens during ´tearDown´ when ´close_all_tabs´ from the WindowManager class is called. The ´close´ method itself checks that there is a contentBrowser available and fails the assert:

Something which is strange in that test when we open this new tab:

There is another listener with id 2147483687 registered, but it never appears as window handle. 

Anyway, we switch to handle 2147483684, clicking on close window, and return immediately because no page load activity has been detected. A further call to get window handles still returns our two tabs:

[task 2017-08-24T01:55:07.496839Z] 01:55:07     INFO -  1503539707493	Marionette	TRACE	262 <- [1,30,null,{}]
[task 2017-08-24T01:55:07.512690Z] 01:55:07     INFO -  1503539707508	Marionette	TRACE	262 -> [0,31,"getWindowHandles",{}]
[task 2017-08-24T01:55:07.516315Z] 01:55:07     INFO -  1503539707514	Marionette	TRACE	262 <- [1,31,null,["2147483649","2147483684"]]
[task 2017-08-24T01:55:07.533496Z] 01:55:07     INFO -  1503539707522	Marionette	TRACE	262 -> [0,32,"switchToWindow",{"focus":true,"name":"2147483684"}]

So it would mean that click() returned too early.
