Btw how the cookie hunting going? You really should follow what Rusbernd wrote and see what content doesn't get deleted when you clear the cache.
Write "about:cache" into the address bar. There click on the "List Cache Entries" under the "disk" option. You're gonna see a list of links with other data, so you can tell which website left that crap on your machine, how large is the size of the data, how many times were dl-d, when was the last time, etc.
