987017 - Javascript popups appear on wrong monitor in multi-display setup (3 displays)

Status: NEW

(Core :: Layout, defect)

Description

[Travis Evans]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release)
Build ID: 20140214013806

Steps to reproduce:

Using a triple-monitor setup on Arch Linux under KDE (one primary monitor at bottom-left, a secondary at bottom-right and a secondary at top-left), Javascript popups persistently open on an arbitrary display instead of the one the parent window is on. Internal Firefox dialogs and new windows opened with Ctrl+N do not exhibit this problem.

I retested with fresh user profile under a different system user account—still same problem.


Actual results:

I open Firefox on primary (bottom-left) monitor and go to http://www.i-am-bored.com/pop_up_blocker_test.html and click the “Click Here - You SHOULD get a pop-up window by clicking this” link. Popup appears on bottom-right display every time.

Or, I go to http://www.nws.noaa.gov/climate/index.php?wfo=ict and click the OK button under “4. View” and get a popup on the upper-left display every time (which is usually off, so I never see it and the site appears broken!).


Expected results:

Popups should have appeared on primary monitor, where the main window was.
