Recently I tried to add a new favorite toan existing folder on a toolbar and nothing happen.
That is I click done to add the linkbut nothing happen, no message was given.
However I can add a favorite link to afolder that is not on the toolbar.
Just to note, my toolbar has 11 folderson Google chrome.
