Most of the Toolbar Icons at the top of my PC are missing. Also the information normally shown on the left hand column such as bookmarks, etc are also missing. All it shows is History and below it are months and dates. This happened after I started to delete "Ask" and some other unnecessary icons. Now the only thing appearing on the Top Toolbar are things such ReferenceBoss, Reference, Dictionary, Thesaurus, Wikipedia and such, and two Search bars. Any help is appreciated.
