Problem installing contacts sidebar in Mozilla Thunderbird

more options

I have downloaded the add-on: Contact Sidebar to my hard drive but am unable to install it into my Mozilla Thunderbird. What do I need to do to install it? If there is an alternative to using contact sidebar to direct my emails (without an add on) I would like to try it. I have had trouble with this for a few weeks now so I would very much appreciate any help you can give me.
