1066941 - Confirm close multiple tabs should consider tabs with content only

Status: RESOLVED DUPLICATE of bug 487166

(Firefox :: Tabbed Browser, enhancement)

Description

[Ed Avis]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:32.0) Gecko/20100101 Firefox/32.0
Build ID: 20140831201947

Steps to reproduce:

Start Firefox.  It appears showing a single tab.  Browse to some site with that tab.

Then hit Ctrl-T to open a new tab.  To start with, this new tab appears with title 'New Tab' and shows the thumbnails of commonly used sites.

Then, click the X icon in the Firefox window decorations to close Firefox.


Actual results:

A confirmation dialogue box appears asking if you want to close multiple tabs.


Expected results:

In this case, although there are two tabs open, one of them has never been used and so there is no work to be lost if it is closed.  Therefore Firefox should not prompt about closing multiple tabs in this case.

The warning should appear only if there are multiple tabs with content in them.  Blank or 'New Tab' tabs should not be included in the check, since it is always safe to close them.
