302649 - Closing a window incorrectly brings up "closing multiple tabs" warning if other windows have multiple tabs

Status: VERIFIED INVALID

(Firefox :: Tabbed Browser, defect)

Description

[Wayne Pollock]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

When closing a window with no tabs (just the one), the warning box about closing
windows with multiple tabs appears.  It shouldn't.  This behavior occurs when
another Firefox window does have multiple tabs.

Reproducible: Always

Steps to Reproduce:
1. Open Window
2. Create new tab
3. Open second window
4. Close second window

Actual Results:  
The closing window with multiple tabs warning appears.

Expected Results:  
Close the window.

This happened on 1.4 too, I never tried it on other versions but I bet it has
the same behavior.

I've only confirmed this bug on Windows platforms.

Works for me. Does this happen also if you run Firefox in the safe mode or with
disabled extensions?

The problem goes away in safe mode.  How do I selectively turn off (or on from
safe-mode) extensions, to track down the culprit?  I looked under help and
on the FAQ but didn't see how to do this.

I figured out that the problem goes away if I disable the "Duplicate Tab"
extenion, version 0.5.1.  I have filed a bug report for the extension
(#11146 at bugzilla.mozdev.org).  I guess this bug should be closed.
