From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; 0.8.1) Gecko/20010310 BuildID: 2001031008 In the sidebar bookmarks manager, if one selects a folder, drags it around, decides to put it back, and accidentally puts it "in itself", it proceeds to disappear. Reproducible: Always Steps to Reproduce: open sidebar bookmark tab select a folder drag it around, then back on itself (not above or below) release mouse Actual Results: The folder is gone. I can't find it anywhere. Expected Results: Something should kick in to tell mozilla to just keep the folder in place instead of trying to put it inside itself, which causes a rip in the space-time continuum and sucks in my poor bookmark folder.
