How do you delete a toolbar you dont want anymore?

i downloaded vuze but now im stuck with the toolbar and i said i didnt want it when i was downloading it. i have deleted all remnants of vuze and restarted computer 3 times and its still on my browser. i use google chrome and sometimes firefox. they both have it. i tried right clicking to get rid of it also, but i dont seem to be having any luck getting it off of the browser at all. can someone please help me with how to get it off of here??????
