245786 - The X to close the last tab should be disabled when only one tab is open

Status: RESOLVED DUPLICATE of bug 156082

(SeaMonkey :: Tabbed Browser, defect)

Description

[Niels Basjes]

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

Uncheck the checkbox at "Preferences" -> "Navigator" -> "Tabbed Browsing" ->
"Hide the tab bar when only one tab is open".

Now open the browser and make sure that only 1 tab is open (the content of that
window is irrelevant).
If you rightclick on the tab then the "Close Tab" menu item has correctly been
greyed out (i.e. inactive). 
On the far right hand side of the tab bar is a button with an X on it. This is
essentially the same action as the "Close Tab" menu item of the currently active
tab. 
However this button is NOT greyed out and continues to function, in this
situation it removes the entire Tab bar.

I think this button should be greyed out in sync with the "Close Tab" menu item.


Reproducible: Always
Steps to Reproduce:
As described above.
Actual Results:  
I can close the tabbar with the X button.

Expected Results:  
The X button should be disabled.

I've been able to reproduce this issue in exactly the same way with Mozilla 1.6
on both Windows 2000 and Fedora Core 2 (Linux).

seems to amount to a bug 129550 dupe

Jag, who implemented this behavior (in Bug 150099) had earlier held the same
view as the reporter of this bug (see Bug 109651, comments 12 and 13). Should
this be resolved as WONTFIX, or should the original solution return? Several
good reasons to go for the latter are given in Bug 150099, comment 28. It might
be a good idea to re-evaluate them.

[Prognathous]

Come to think about it some more, this is a dupe of 156082, as not hiding the
tab bar would probably mean reinstating the previous behavior (which this bug
asks for).

Sorry for the spam,
