384633 - Opening a folder of links is a destructive operation

Status: RESOLVED DUPLICATE of bug 300198

(Firefox :: Tabbed Browser, defect)

Description

[Robert Morelli]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2

When opening an entire folder of links, such as by middle clicking on a toolbar folder, all open tabs are closed and a new tab is opened for each menu item in the folder. As far as I can tell, there's no way to undo this action, so it must be considered a destructive action. If you have dozens of tabs open, it may in fact be a great deal of work to recover the state of the browser after such an operation. Moreover, it's easy to do this inadvertently. Firefox presents no warning before taking this highly destructive action and offers no way to undo it. I therefore consider this a serious bug in Firefox's design.
 
I am aware that you can change the behavior by toggling
browser.tabs.loadFolderAndReplace to false in about:config
but I still consider this a very serious bug, because that option is true by default, and some users may want to keep it to true even though they do not want to inadvertently lose a great deal of work when the action is invoked inadvertently.

Reproducible: Always

Steps to Reproduce:
1.Middle click on any toolbar folder
