218517 - Pref needed: tabbed browser window 'Are you sure?' close confirmation dialog box when multiple open tabs are going to close preference

Status: RESOLVED FIXED

(SeaMonkey :: Tabbed Browser, enhancement)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624

There should be a preference (default: enabled, IMO) to enable an 'Are you
sure?' confirmation dialog box when a window is closed that has multible tabs
open.  

For the umpteenth time, I closed a window when I meant to close a tab.  Arrgh!  

Lost posts I was in the middle of editing, forms I'd partly filled,...

Reproducible: Always

Steps to Reproduce:
Open a window with several tabs, close the window.
Actual Results:  
The window and all the tabs close. 

Expected Results:  
Confirm that I really wanted to close all the tabs.

I've looked through about:config and
http://www.mozilla.org/unix/customizing.html#prefs
and don't see an extant pref.
The UI would probably go in 
In Preferences...Navigator...Tabbed Browsing

Perhaps 
browser.tabs.confirmMultiTabClose boolean?  
(or something more generic - browser.confirmClose: 0= confirm nothing; 1=
confirm MultiTabClose; 2= confirm all manual closures) 

This bug is causing me to lose data, but the fix is an enhancement; I'll leave
it as severity normal as a compromise?

This already exists. Try a newer build.

<Posting collision; thanks Andrew!  Here's my post:>

Bug 191578 is related (but NOT a dupe), and a proposed fix to it uses/creates
pref browser.tabs.warnOnCloseOther.

http://bugzilla.mozilla.org/show_bug.cgi?id=103354#c9 suggests this bug be fixed
too, with many people piping up in that bug's comments that the closely related
'close other tabs' feature it too easy to activate, and providing workarounds.

I find it very difficult to unlearn the deeply ingrained behaviour of clicking
the window close box to close what I'm looking at, and posts to the mentioned
bugs show MANY others would not have lost data if this bug was fixed. I love
tabbed browsing.

Marking fixed: read http://bugzilla.mozilla.org/show_bug.cgi?id=108973#c161
(OT: Now I just have to decide whether to switch to wamcom, 1.5b, Thunderbird
and Firebird, or a nightly... or wait!)

Reopening, clarifying summary: It's not fixed in the UI; there's room in
Preferences...Navigator...Tabbed Browsing to toggle the browser.tabs.warnOnClose
pref.

The Dialog that is available in 1.5b 2003082704 is ok, it only should have the
button: 'Close only current tab' on it, because this is probably what the user
wanted.

Ivar, you're right.  Undoing my changes. Back to fixed, old Summary.
