Comment 244 for bug 193141

Same with control-click:

Steps:
- Use the bookmark organizer to make a folder under the bookmarks toolbar folder and populate it with a couple of individual bookmarks.
- Control click on a folder in the bookmarks toolbar (under the address bar)

Actual (FF3):
- The folder opens as if an unmodified left click had been made

Expected (and FF2 behaviour):
- Each bookmark in the folder is opened as a tab.

The above is also valid if "control-click" is replaced with "middle-click".
