Uninstallation problem with Mozilla Firefox

I have installed Mozilla firefox web browser on my home computer,and now wanted to switch over to Opera, for that I uninstalled firefox but After uninstalling Firefox I can't get it removed from the Common file directory. It's in the Mozilla shared folder and no matter how many times I delete but it it still comes back. The main file in "Programs" gets deleted when removing using remove programs in control panel and there is nothing else in the program listing. My firewall keeps telling me it has stopped Firefox from connecting to the internet but it's now getting to be a pain. Mozilla just refer me to the windows removal system which I've already done.

I'm running windows XP SP2. please help.

Thanks
