hi guys,need help with firefox and tor.

i had tried to install the latest tor release,but it didn't install properly over my current one,so i uninstalled it,along with privoxy and my firefox browser,in an attempt to start affresh.

but now when i reinstall firefox after uninstalling it fully as well as deleting wots left after,it still has all my plugins there.something appears to be left of tor as well because whenever i tried to reinstall that and restarted my system,it would say that something was already using the ports that i think privoxy uses.

how do i get rid of this crap n start again,as i have some stuff on my hard drive i'd rather not lose and have no discs left....sorry if this is in the wrong place but i'm kinda desperate.
