Login addresses

Can anyone tell me how to delete addresses currently showing in the address bar. I have several which are no longer valid and would like to get rid of them but can't seem to be able to delete them.

Thanks.

choose "tool" -> "settings" in the menu. go to "history" in the appearing window. choose the adresses to delete in the list box and press the "delete" button or the "empty" button to delete all addresses from the history.

Thank you very much. Fixed my problem.
