User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171112125346

Steps to reproduce:

Two monitors plugged into a Lenovo docking station with Notebook


Actual results:

When i have two different windows of firefox (version 57 quantum) on my two screens displayed, the new version of firefox shows some strange behaviours regarding the layout.

Sometimes it shows the layout of the old FF in the background. Another time it switches to Fullscreen, and overlaps my Taskbar in windows.
Please have a look at the attached screenshot

This looks like a duplicate of bug 1405593. What version of Windows 10 are you running? (You can check by going to the Windows settings, then System, then About (at the bottom of the left sidebar) and then the contents of "Windows specifications" (bottom of the main section)

Yes, this bug 1405593 looks exactly like my issue. I am using Windows version 1511 too. Will this problem be fixed in a later windows version?

I believe so. As far as I understand from bug 1405593 comment 31, Microsoft also no longer supports that version, so it'd be best to update if you are able to either way. Do let us know by commenting here or on bug 1405593 if, after an update to a newer version of Windows, you still see this issue.
