Status: RESOLVED DUPLICATE of bug 222316

(SeaMonkey :: Tabbed Browser, defect)

Description

[Alex Shapiro]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113

If browser is instructed to warn when closing a window with multiple tabs still
open, a confirmation dialog pops up. Clicking Cancel or closing the dialog
window alltogether has the same effect as the other option - closes browser.

Reproducible: Always

Steps to Reproduce:
1. Make sure that browser.tabs.warnOnClose = true in about:config
2. Open a few tabs
3. Close the browser window, a confirmation dialog pops up
4. Click Cancel / the system menu's X button

Actual Results:  
Mozilla closes down the browser window and the tabs.

Expected Results:  
Cancel the closing procedure, leave the browser window open, as if nothing happened

I've only seen this with the downloadbar from mozdev.org installed. Do you have
that add-on, or others, installed?
