Status: RESOLVED DUPLICATE of bug 433675

(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)

This bug has been fixed for the browser main window, but apparently it hasn't been fixed for other types of FireFox windows.

Pressing <Windows>+<TAB> when only the Download Manager window is visible, the Download Manager window gets minimized and is moved to x = y = -32000.

Reproducible: Always

Steps to Reproduce:
1. Open FireFox
2. Open Download Manager window
3. Close FireFox main window
4. Press <Windows>+<TAB>
Actual Results:  
Download Manager window gets minimized and moved to x = y = -32000.

Expected Results:  
The Download Manager window should keep its position.

The Download Manager window can manually be retrieved back to visibility by pressing <CTRL>+<J> twice (hiding it and show it again).

Here's the resulting element from the localstore.rdf file:

<RDF:Description RDF:about="chrome://mozapps/content/downloads/downloads.xul#downloadManager"
                   sizemode="normal"
                   screenX="-32000"
                   screenY="-32000"
                   width="160"
                   height="38" />

I can't reproduce a problem, at least not on Vista.

Download Manager is not moved to a different position on the screen.
Can you retest with the latest version and a new profile:

I can reproduce this behaviour with FF 3.5.3 on Windows 7 every time:

Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.1.3) Gecko/20090824
Firefox/3.5.3

It's now not even possible to re-maximize the window because Windows 7
implements a new Jump List feature, disabling the usual context menu.

Steps to reproduct:

* Have only FF window opened.

* Hold the <FLAG> key pressed and quickly press <TAB> twice.
