Status: RESOLVED DUPLICATE of bug 411029

(Firefox :: Tabbed Browser, defect)

Description

[J. Barry]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

Previously (2.0.0.16 and older).  When I middle mouse clicked on a tabbed folder, Firefox would open all the bookmarks in that folder.  Now, since 3.0.1,
Firefox will open the bookmarks, but will add an unwanted "(Untitled)" tab.  This seems to only happen when I open a new Firefox session.  Firefox will not create the "(Untitled)" tab if there is an open web page.

Reproducible: Always

Steps to Reproduce:
Open Firefox browser.

1. Create a "Mail" folder in bookmarks
2. Create 2 bookmarks.  ie AOL mail and Yahoo! mail.
3. Middle mouse click "Mail" folder tab.

Actual Results:  
Three tabs will opened, "Untitled", "AOL" and "Yahoo!"

Expected Results:  
Two tabs should open "AOL" and "Yahoo!"

That's no extra tab that's added, the blank tab is the one you seen before opening the bookmarks group. The only difference to Firefox 2.0 is that middle-clicking a bookmark folder no longer overwrites already open tabs (although keeping the blank tab around doesn't make too much sense in this case).
