User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0 Build ID: 20170824053622 Steps to reproduce: 1. connect 2 external monitors to a laptop, primary monitor (1) on the right side, secondary monitor (2) on the LEFT side. Laptop screen closed (off) 2. move firefox window on the higher (almost top) side of the secondary (left) monitor, without maximizing window: scroll works 3. move firefox window some 3-4 centimeters downwards and try to use scroll wheel again: scroll does not work anymore 4. move firefox window up again: scroll wheel works again Firefox 55.0.3 (32 bit) running on a DELL Latitude 7440 with two monitors LG 24MB35PY-B (Model 24MB35PYI) Actual results: scroll wheel not working for certain positions of the firefox window in the secondary monitor, if this is on the left side of the primary monitor, but working for other positions (upper side of the screen or maximized= working, lower position of the window=not working) The problem is not occurring on the primary (right) monitor, or in the case the secondary monitor is on the right of the primary monitor Expected results: scroll wheel shall always work, independently from the actual position of the firefox window within the secondary (left) monitor screen
