FireFox Search HiJacking

when I was messing around with ICQ 6 I installed it with all the bells and whistles, as such it nabbed Google away from my default FireFox address bar search replacing it with ICQ Search :

to restore order...
in the FireFox address bar type about:config
in the Filter field type keyword.URL
double click the entry and replace ICQ search with
http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q=
click OK and you're done :)
