723758 - Firefox "reorders" windows when saving session

Status: RESOLVED DUPLICATE of bug 712763

(Firefox :: Untriaged, defect)

Description

[Jesus Cea]

User Agent: Mozilla/5.0 (Ubuntu; X11; Linux x86_64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1
Build ID: 20120117091224

Steps to reproduce:

1. Open a "clean" Firefox: no extensions, clean profile.
2. Configure it to restore session when starting.
3. Open a handful of windows, to different sites.
4. Select (move to front) a window to front. Choose a Windows from the middle. That is, if you open five windows, choose the window 2, 3 or 4.
5. Quit Firefox gracefully.
6. Restart Firefox.


Actual results:

The active window when you shutdown FF will be in the foreground. Good. But the windows in the taskbar/windows order, will have a wrong order. That is, you selected windows will be now the FIRST Firefox window. If you repeat the process a few times, your window order in the taskbar will be esentially random, defeating any muscular memory/spatial memory.


Expected results:

This is a problem introduced in FF 9.0.0. Previous versions of FF will keep the window order constant (the order you opened the windows originally), with the foreground window being the window in the foreground when you shutdown/crash.

Keeping the window order constant is intuitive and allows muscular/spatial memory. I don't have to look for the window I need, I "know" that it is the sixth. For years :-)

This can be reproduced under Linux and Mac. I didn't tried Windows.

Does it reverse the order like bug 712763?

Comment 2

No, it puts the foreground window as the "first" window in the session.


Reading that bug, this is a duplicate.
