I am still setting up my new computer (Windows 7), and while my Mozilla settings transferred nicely, I was trying to delete some the the old *most visited* pages under the drop down menu of same name and must have inadvertently clicked somewhere I shouldn't have as my *Most Visited* tab is now absolutely gone and I have tried to restore default bookmarks but nothing seems to happen. *Most Visited* tab is such a nice feature and I don't wish to lose it. Thank you for any suggestions.
