Bookmarks should delete properly but sometimes there may be problems, but may I ask some other questions first so that I may try to give the correct advice. *Are you trying to delete every bookmark you have ? <br />or just some of them ? * Has it they been ok when deleting bookmarks before ** yes/no, not tried before * May I ask any particular reason you wish to delete these bookmarks ? **Is it just because you do not wish them to show in the address bar,and the addressbar listing ? <br />(You may prevent that but keep the bookmarks) **SEE [[Remove websites from the Awesome Bar suggestions]] It would help to have similar information about History. Note also the private browsing option that prevents History etc being saved for a particular Window. * [[Private Browsing - Browse the web without saving information about the sites you visit]]
