Comment 6 for bug 874936

Please do auto-close. I don't have a Unity install to test this on, 2D or otherwise. I don't plan on using community-supported Unity, partly because I think there were other reported bugs that I didn't hear anything about.

Also, it looks as if the root issue is fixed for new Firefox profiles. *If* I create a new profile, then the default folder when creating a bookmark is "Other Bookmarks" (heh). So you don't end up with thousands of items in the Bookmarks menu. Unless you deliberately asked for every one of them.

I wouldn't say the occurrence was a one-off, seems clear from comments that it was consistent. :-P.
