In IE8 under the options->complete there is an autocomplete settings button. Once clicked there are various check boxes for autocomplete. However, ccleaner has only the checkbox for autocomplete forms and none of the others under address bar including the usernames & passwords, The same for firefox there is no option to clear the address bar history which would be set as favorites, address bar or nothing. These fall under options->privacy-> location bar.
I can't find the equivalent under chrome although it saves address bar info and is displayed to to the user under the drop down arrow.
Thus, ccleaner latest version needs a fix to remove all this history that is stored in the address bar of the varous browsers.
The same probably is true for in privacy filtering too.....
