Description

[Ryan Li]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2a1pre) Gecko/20090304 Minefield/3.2a1pre
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2a1pre) Gecko/20090304 Minefield/3.2a1pre

When there's only one tab left, I cannot close it and return to a blank page, as firefox 3.0 does.

Reproducible: Always

Steps to Reproduce:
1. Open any web page in a tab.
2. Try to close it
Actual Results:  
Nothing happens, and the button is gray, firefox prevents you from closing the last one!

Expected Results:  
Close the tab as it used to do, or provide an option for user to choose which way firefox should behave.

Middleclicking the last tab replaces it with a blank page for me

@Mardeg:

Maybe this behaviour is Linux-only?
Can anyone confirm this?

Windows Vista, latest trunk, new profile: 
When I middle click on the last tab, nothing happens.
With the old setting still present in my default profile I get a blank tab.

Maybe caused by Bug 456382? Will try to check later.

I get no button with one tab open, this is the new expected behavior. (I recall beltzner talking about it)

But I think that should be a choice? Since I am quite used to the old behaviour.

[Mike Beltzner [:beltzner, not reading bugmail]]

This is working as expected on Linux, OSX and Windows, fwiw:

 - the close button isn't shown on the last tab
 - the middle mouse button doesn't close the last tab
 - ctrl+w on the last tab closes the entire window

(see bug 392870 and dependencies such as bug 348031 and bug 456405 for original rationale as to why we do this)

See bug 455852 - browser.tabs.closeWindowWithLastTab exists for this purpose.

I am using the old behaviour (pre 2) with browser.tabs.closeButtons set to 3, if i use it on the last tab, the whole windows closes, too.

Stefan, if you think this is a bug (I think it is because it is unexpected given the recent change), please file a new bug.
