Status: RESOLVED DUPLICATE of bug 440895

(Firefox :: Session Restore, defect)

Description

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0

If I have multiple windows open in different Spaces, on shutdown and restore each window will restore into the currently active Space.

Reproducible: Always

Steps to Reproduce:
1. Enable OS X's Spaces feature with at least 2 open Spaces.
2. Create a session with windows spread across multiple Spaces.
3. Shutdown and restore the session.
Actual Results:  
If you don't switch Spaces during the restore, all windows are restored into the currently active Space.

Expected Results:  
Windows are restored to their original Spaces.

This may obviously be useful for other OSes with virtual desktops, but I've no idea how difficult they may be to implement. There's the question of how to handle a Spaces configuration change in between close and restore, but (IMO) an adequate solution would simply be to attempt to restore a window into the correctly-numbered Space, then into the nearest number Space if the original is not available.
