501020 - Unexpected warning about closing tabs when Download form is open.

Status: RESOLVED DUPLICATE of bug 354894

(Firefox :: Tabbed Browser, defect)

Description

[Virtlink]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; nl; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.11 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; nl; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.11 (.NET CLR 3.5.30729)

When any non-modal dialog is open, Firefox will warn me when I want to close the last instance of Firefox. My tabs are saved (set in the preferences) as they should, but the warning is unexpected. When all of Firefox' forms have been closed, my tabs respawn as expected. However, opening a new instance of Firefox while not all forms are closed will cause my tabs to be lost. This may be two different but closely related bugs.

Reproducible: Always

Steps to Reproduce:
1. Open a new single instance of Firefox.
2. Set in the preferences that Firefox has to show the tabs of the previous session, and that Firefox has to warn when closing multiple tabs.
3. Open two or more tabs in the Firefox instance.
4. Open the Downloads dialog.
5. Close the Firefox main form (with the two tabs in them).
Actual Results:  
Firefox warns me that I am about to close multiple tabs.

Then, reopening an instance of Firefox (through the Firefox icon) before closing the Downloads dialog will cause me to lose the tabs from the previous session, and Firefox starts with the start page.

Reopening an instance of Firefox (through the Firefox icon) after closing the Downloads dialog will correctly show my tabs from the previous session again.

Expected Results:  
Firefox should not warn me when I save the tabs from the previous session. Firefox responds correctly (i.e. no warning) when no other dialogs (such as the Downloads dialog) are open.

Firefox should restore my tabs when reopening a Firefox instance, when no Firefox main forms are open, even tough any Firefox dialog (such as Downloads) is currently visible.

This doesnt look like a major issue. If someone can confirm this can move forward
