In previous releases when you clicked a file(group) bookmark, it opened all sub bookmarks in a new tab, and any presently open tabs were reused/replaced. As of 1.1 the new tabs created by the group bookmark are just added to the current window! (and will continuously append new tabs every time you click the bookmark) This is very frustrating because the first window (which must always remain open otherwise mozilla/browser closes altogether) is just wasted, its content never changes when opening group bookmarks/tabs.

Duplicate. Won't Fix. This is the intended behavior.

Do you have a link to the original bug? Why is the behavior of 1.1 preferred?

bug 134800 a quick search of browser:tabbed browser, changed in 60 days, resolution:invalid, wontfix, duplicate would have led you to the bug.
