Mozilla Firefox stores your website browsing history by default, displaying it under the address bar as suggestions when you start typing a new address. To protect your privacy, erase the Web browsing history. Note that you can't recover the data after you erase the history. You may still see your bookmarks -- identified by a blue star -- in the list of suggestions after you erase the history; you can delete them later if you wish.
