Mouse help!

Hi all, here is sort of a trivial question but I have a multi-button mouse that I use, and I was wondering if there is any way to get the "back" and "forward" buttons on the side of my mouse to work for internet browser navigation? I've been using my MBPro for quite a while now and have always used the button on the browser itself or the multi-touche trackpad since the mouse didn't work but I would definitely like to know if there is a utility or built in feature I can use to utilize all buttons of my mouse?

Thanks guys and gals

 

Thanks for the heads up. Didn't know why I didn't think about that earlier - I downloaded the Logitech control center and figured out all my buttons. Thanks!
