User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

(Firefox 42.0 in Windows 7)

Open a window with and specify width, height, top and left specs.
Example:"/", "title", "width=500, height=200, top=50, left=100", false);

Example in (popups need to be allowed)

Actual results:

The properties of the popup window do not match the specifications passed to

I get: innerWidth 546 innerHeight 218 outerWidth 561 outerHeight 294 screenX 109 screenY 54

Expected results:

The properties of the popup window match the specifications, which is actually the case when you open the jsfiddle above in Google Chrome. It reports: innerWidth 500 innerHeight 200 outerWidth 510 outerHeight 260 screenX 100 screenY 50

I suspect I understand where this problem is in our code, but I want to be sure.

Reporter - are you able to reproduce if the window is in the "restored" state (so not maximized)? If you can't, but you can reproduce when maximized, then I understand how this bug works and can describe it here.

(Tested in Firefox 47.0.1)
(Assuming you mean that the invoking window should be in restored state, not the popup itself)

The restored/maximized state did not make any difference but the overall firefox configuration appears to play a role:

In a firefox started with a new profile I just created, running this jsfiddle reports:
  innerWidth 497 innerHeight 198 outerWidth 511 outerHeight 259 screenX 98 screenY 49
But this does not change with the restored/maximized state, nor does it when having multiple windows opened in different states.

Disabling all plugins in my normal profile did make a small difference to the original bug report:
  innerWidth 546 innerHeight 218 outerWidth 561 outerHeight 279 screenX 108 screenY 54
Still no change if invoking it in a restored or maximized window.
