Comment 9 for bug 1017828

This bug went away when I disabled the Global Menubar Integration extension/add-on. However, even though I still have the Global Menubar Integration extension disabled, it has now returned with a new version of Firefox as a result of recent updates to 12.04. I note that the Global Menubar Integration is no long shown in Firefox's list of add-ons (obtained using men item Tools>Add-ons).

PS I had the Global Menubar Integration extension disabled because it caused delays in displaying the contents of Bookmarks folders as well as causing this bug.
