With tab drag & drop, the new window appears off-screen


(Firefox :: Tabbed Browser, defect)

39 Branch
Not set





(Reporter: vincent-moz, Unassigned)


User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150630154324

Steps to reproduce:

1. Open Firefox in safe mode.
2. Open a new tab.
3. Drag & drop this tab inside Firefox (to open it in a new window).

Actual results:

The new window appears completely off-screen. It is not possible to use it at all. I need to quit Firefox and restart it.

For instance, the geometry of this new window (as output by the xwininfo utility with the id obtained from the window list given by the FvwmWinList module of my window manager Fvwm): 2093x1773+3568+520 on a 3200x1800 screen.

Expected results:

The new Firefox window should appear within the screen limits.

Note: if I use the "New Window" function from the Firefox menu, there's no such problem because my Fvwm configuration lets me position the window if there isn't enough room (ActivePlacement feature).

I can no longer reproduce this bug, but the window can appear slightly off-screen (still under Debian/unstable with the FVWM2 window manager). I wonder whether Firefox mishandles/ignores the size of the window decorations (title bar and window borders), as some other GTK-based applications have a similar issue when remembering the position of windows.
