457783 - When closing the only tab that is open, the entire browser closes

Status: RESOLVED DUPLICATE of bug 456405

(Firefox :: Tabbed Browser, defect)

Description

[Matthew Knowlton]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b1pre) Gecko/20080925033548 Minefield/3.1b1pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b1pre) Gecko/20080925033548 Minefield/3.1b1pre

Instead of going to the about:blank that the browser should go to when the last open tab is closed, the browser just completely closes. Saw this begin happening with this version of Minefield. Earlier released versions of Firefox would just pull up an about:blank

Also noteworthy is that if you try to reopen the browser real quick after it closes it says that it is still open but not responding, but after waiting a few moments you can open it back up.

Reproducible: Always

Steps to Reproduce:
1. Close all but one tab
2. Close that one tab now
Actual Results:  
Browser vanishes and closes, no crash window though.

Expected Results:  
should bring up an about:blank

Matthew: Please see Bug 392870#c47, I think this might explain what you are seeing. As the commenter notes, the browser does not close when you are running on Mac.
