address bar clearing

Greetings, fellow Piriformers!

This may be the only time I need to ask for help since the CCleaner (free version) is so easy to use, but I can't seem to format my program to delete address bar entries. It worked one time, but due to my inadvertently checking or unchecking certain options listed under the Windows and Applications tabs, the roster of entries remains, even after closing and logging on anew.

I'd appreciate any tips for what is, I'm sure, an easily solved problem. My operating system is Windows 7 Home Premium. Thank you!

address bar in? Explorer? Ie? Chrome? Firefox?

For a 3rd party web browsers it would possibly be the History option in CCleaner. For Internet Explorer I'd imagine it would be the Recently Typed URLs and possibly also the History.
